  • How can I tell what command is running on the remote end of an ssh connection?

    - by user268385
    Tl;dr - how do I find the name of the command (eg $BASH_COMMAND) running on the remote end of an ssh connection? ... My example setup is two tmux vertical panes, LH pane runs a local vim session with vertical split, RH pane runs an ssh session running vim, again with a vertical split. Using tmux-navigator I can navigate from left to right over the first 3 vim buffers, but the 4th (far right hand one) is inaccessible. The reason for this is that tmux-navigator tests the value of 'pane_current_command' and compares it to 'vim' before deciding which keystrokes to dispatch. On the right hand tmux pane, the current command is 'ssh' and not 'vim'. What I want to do is test for (pane_current_command =~ 'ssh'), and if so, examine the command that is running on the far side of the connection? I cannot find a way to get hold of this, so any suggestions would be welcome? For information, the problem is almost the same as this one, but without the nested tmux sessions: https://github.com/christoomey/vim-tmux-navigator/issues/12

  • Is there a way to get x-mouse-type scrolling under the cursor for child windows within one program window?

    - by eigor40
    I've been messing with X-mouse setups, to enable scrolling for whatever is under the cursor, regardless of whether it has the focus or not. I've found several ways to get this to work between various 'parent' windows (Win7's built-in mouse options, WizMouse, etc), but I've found nothing that will do the same thing with (for example) several child windows with spreadsheets, open at the same time in one parent Excel window. I have the spreadsheets set up so that two are visible in the window at the same time, but I always have to click on either one to scroll it up and down. I'd love to be able to scroll these just by moving the mouse and doing the scroll, without the extra focus-change-click. I am not a big fan of running separate parent windows for each spreadsheet, which I realize would be something of a workaround. I'd rather keep the single parent Excel window, but still have X-mouse functionality within it. Anyone know of any way to achieve this? I'd call it "XMouse for Child Windows".

  • Need help with Android TableLayout alignment

    - by Ben L.
    I'm trying to build a calculator layout using TableLayout, but the last two rows aren't aligning with the rest of the layout. Is there something wrong with my layout XML? What I'm trying to do would be easier to accomplish in HTML (<td> with colspan or rowspan), so should I try converting this into a WebView? Code is as follows: (Screenshot) <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" /> <TableLayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:stretchColumns="*"> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> <Button android:id="@+id/Button08" android:textSize="16pt" android:text="^" android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="wrap_content" /> <Button android:id="@+id/Button09" android:text="÷" android:textSize="16pt" android:layout_height="fill_parent" android:layout_weight="1" android:layout_width="wrap_content" /> <Button android:id="@+id/Button10" android:text="×" android:textSize="16pt" android:layout_height="fill_parent" android:layout_weight="1" android:layout_width="wrap_content" /> <Button android:id="@+id/Button11" android:textSize="16pt" android:text="-" android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="wrap_content" /> </TableRow> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="2"> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1"> <Button android:id="@+id/Button01" android:text="7" android:textSize="16pt" android:layout_weight="1" android:layout_height="wrap_content" android:layout_width="fill_parent" /> <Button android:layout_height="wrap_content" android:textSize="16pt" android:text="4" android:id="@+id/Button05" android:layout_weight="1" android:layout_width="fill_parent" /> </LinearLayout> <LinearLayout android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1" android:layout_width="fill_parent"> <Button android:id="@+id/Button02" android:layout_height="wrap_content" android:text="8" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" /> <Button android:layout_height="wrap_content" android:textSize="16pt" android:text="5" android:id="@+id/Button06" android:layout_weight="1" android:layout_width="fill_parent" /> </LinearLayout> <LinearLayout android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1" android:layout_width="fill_parent"> <Button android:id="@+id/Button03" android:text="9" android:textSize="16pt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" /> <Button android:textSize="16pt" android:text="6" android:id="@+id/Button07" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" /> </LinearLayout> <Button android:id="@+id/Button04" android:text="+" android:textSize="16pt" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1" /> </TableRow> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="2"> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="2"> <LinearLayout android:layout_weight="1" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/Button02" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="1" /> <Button android:textSize="16pt" android:id="@+id/Button06" android:layout_weight="1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="2" /> </LinearLayout> <Button android:id="@+id/Button01" android:layout_height="wrap_content" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" android:text="0" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1"> <Button android:id="@+id/Button03" android:textSize="16pt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:text="3" /> <Button android:textSize="16pt" android:id="@+id/Button07" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:text="." /> </LinearLayout> <Button android:id="@+id/Button04" android:textSize="16pt" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1" android:text="=" /> </TableRow> </TableLayout> </LinearLayout>

  • jQuery gallery scrolling effect with ease

    - by Sebastian Otarola
    So, I got this page from a friend and I think the gallery is amazingly done. Too bad it's in Flash ; http://selected.com/en/#/collection/homme/ Now, I'm trying to replicate the effect with jQuery. I've made all the loco searches on google one could think of. Zooming the picture is not a problem, the problem lies within the scrolling, how they come together at the ease part. I'm looking for solution in how to make the thumbnail animate when you scroll the page, they drag behind and infront of each other in a very subtle way - I've got (With a lot of help from Whirl3d in the jQuery-irc channel) this for the scrollup/down part of the mouse but the scrolling goes haywire; I Thought I post it here where I've come many times to get answers to a lot of questions and code-errors. This is my first post in stackoverflow and I know you guys are geniuses! Give it a shot! Thanks in advance! jQuery Part $(document).ready(function() { var fronts=$(".front"); var backs=$(".back"); var tempScrollTop, currentScrollTop = 0; $(document).scroll(function () { currentScrollTop = $(document).scrollTop(); if (tempScrollTop < currentScrollTop) { //Scroll down fronts.animate({marginTop:"-=100"},{duration:500, queue:false, easing:"easeOutBack"}); backs.animate({marginTop:"-=100"}, {duration:300, queue:false, easing:"easeOutBack"}); console.log('scroll down'); } else if (tempScrollTop > currentScrollTop) { //scroll up fronts.animate({marginTop:"+=100"},{duration:500, queue:false, easing:"easeOutBack"}); backs.animate({marginTop:"+=100"}, {duration:300, queue:false, easing:"easeOutBack"}); console.log('scroll up'); } tempScrollTop = currentScrollTop ;}) ;}); The HTML <html> <head> <link rel="stylesheet" type="text/css" href="style.css" /> <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script> <script type="text/javascript" src="http://www.paigeharvey.net/assets/js/jquery.easing.js"></script> <script type="text/javascript" src="gallery.js"></script> <title>Parallax testing image gallery</title> </head> <body> <div class="container"> <div class='box front'>First Group</div> <div class='box back'>First Group</div> <div class='box front'>First Group</div> <div class='box back'>First Group</div> <br style="clear:both"/> <div class='box front'>Second Group</div> <div class='box back'>Second Group</div> <div class='box front'>Second Group</div> <div class='box back'>Second Group</div> <br style="clear:both"/> <div class='box front'>Third Group</div> <div class='box back'>Third Group</div> <div class='box front'>Third Group</div> <br style="clear:both"/> </div> </body> And finally the CSS Part .container {margin: auto; width: 410px; border: 1px solid red;} .box.front{border: 1px solid red;background-color:Black;color:white;z-Index:500;} .box.back {border: 1px solid green;z-Index:300;background-color:white;} .box {float:left; text-align:center; width:100px; height:100px;}

  • Day 2 - Game Design Documentation

    - by dapostolov
    So yesterday I didn't cut any code for my game but I was able to do a tiny bit of research on the XNA Game Development Technology and the communities out there and do you know what? I feel I'm a bit closer to my goal. The bad news is today I didn't cut code either. However, not all is lost because I wanted to get my ideas on paper and today I just did that.  Today, I began to jot down notes about the game and how I felt the visual elements would interact with each other. Unlike my workplace, my personal level of documentation is nothing more than a task list or a mind map of my ideas; it helps me streamline my solutions quiet effectively and circumvent the long process of articulating each thought to the n-th degree. I truly dislike documentation (because I have an extremely hard time articulating my thought and solutions); however, because I tend to do a really good job with documentation I tend to get stuck writing the buggers. But as a generalist remark: 'No Developer likes documentation.' For now let's stick with my basic notes and call this post a living document. Here are my notes, fresh, from after watching the new first episode of Merlin second season! Actually, a quick recommendation to anyone who is reading this (if anyone is): I truly recommend you envelope yourself in the medium or task you're trying to tackle. Be one with moment and feel it! For instance: Are you writing a fantasy script / game? What would the music of the genre sound like? For me the Conan the Barbarian soundtrack by Basil Poledouris is frackin awesome. There are many other good CD's out there, which I listen to (some who even use medival instruments, but Conan I keep returning to. It's a creative trigger for me. Ask yourself what would the imagery look like? Time to surf google for artist renditions of fantasy! What would the game feel like? Start playing some of your favorite games that inspire you, be wary though, have some self control and don't let it absorb your time. Anyhow, onto the documentation... Screens, Scenes, and Sprites. Oh My! (groan...) The first thing that came to mind were the screens, I thought the following would suffice: Menu Screen Character Customisation Screen Loading Screen? Battle Ground The Menu Screen Ok. So, the thought here is when the game loads a huge title is displayed: Wizard Wars. The player is prompted with 3 menu items: 1 Player Game, 2 Player Game, and Exit. Since I'm targetting the PC platform, as a non-networked game to start, I picture myself running my mouse over each menu option and the visual element of the menu item changes, along with a sound to indicate that I am over a curent menu item. And as I move my mouse away, it changes back, and possibly an exit mouse sound. Maybe on the screen somewhere is a brazier alit with a magical tome open right beside it, OR, maybe the tome is the menu! I hear the menu music as mellow, not obtrusive or piercing. On a menu item select, a confirmation sound bellows to indicate the players selection. The Esc key will always return me to the previous screens or desktop. The menu screen must feel...dark, like a really important ritual is about to happen and thus the music should build up. 1 Player Game - > Customize Character(s) 2 Player Game - > Customize Character(s) Exit - > Back to Windows Notes: So the first thing I pick up here are a couple things: First and foremost, my artistic abilities suck crap, so I may have to hire an artist (now that i've said that, lets get techy) graphical objects will be positioned within a scene on each screen / window. Menu items will be represented grapically, possibly animated, and have sound / animation effects triggered by user input or a time line. I have an animated scene involving a brazier or fire on a stick IF I was to move this game to the xbox, I'd have to track which menu item is currently selected (unless I do a mouse pointer type thing.) WindowObject has a scene A Scene has many GameObjects GameObject has a position graphic or animation MenuObject is a GameObject which has a mouse in, mouse out, and click event which either does something graphically (animation), does something with sound, or moves to another screen.  Character Customisation Screen With either the 1 or 2 player option selected, both selections will come to this screen; a wizard requires a name, powers, and vestements of course! Player one will configure his character first and then player two. I considered a split screen for PC but to have two people fighting over a keyboard would probably suck. For XBox, a split screen could work; maybe when I get into the networking portion (phase 2 blog?) of this game I will remove the 2 player option for PC and provide only multiplayer and I will leave 2 player for xbox...hmm... Anyhow...I picture the creation process as follows: Name: (textbox / keyboard entry) - for xbox, this would have to be different. Robe Color: (color box, or something) Stats: Speed, Oomph, and Health. (as sliders) 1 as minimum and 10 as maximum. Ok, Back, and Cancel buttons / options. Each stat has a benefit which are listed below. The idea is the player decides if he wants his wizard to run fast, be a tank and ... hit with a purse.Regardless, the player will have a pool of 12 points to use. Ideally, A balanced wizard will have 5 in each attribute. Spells? The only spell of choice is a ball of fire which comes without question. The music and screen should still feel like a ritual. The Character Speed Basically, how fast your character moves and casts. Oomph (Best Monster Truck Voice): PURE POWAH!!! The damage output of your fireball. Health How much damage you can take. Notes: I realise the game dynamics may sound uninteresting at the moment; but I think after a couple releases, we could have some other grand ideas such as: saved profiles, gold to upgrade arsenal of spells, talents, etc...but for now...a vanilla fireball thrower mage will suffice for this experiment. OK. So... a MenuObject  may need to be loosely coupled to allow future items such as networking? may be a button? a CharacterObject has a name speed oomph health and a funky robe color. cap on the three stats (1-10) an arsenal of 1 spell (possibly could expand this) The Loading Screen As is. The Battleground Screen For now, I'm keeping the screen as max resolution for the PC. The screen isn't going to move or even be a split screen. I'm not aiming high here because I want to see what level of change is involved when new features / concepts are added to game content. I'm interested to find out if we could apply techniques such as MVC or MVVM to this type of development or is it too tightly coupled? This reminds me when when my best friend and I were brainstorming our game idea (this is going back a while...1994, 6?) and he cringed at the thought of bringing business technology into games, especially when I suggested a database to store character information and COM / DCOM as the medium, but it seems I wasn't far off (reflecting); just like his implementation of a xml "config file" for dynamic direct-x menus back before .net in 1999...anyhow...i digress... The Battle One screen, two characters lobing balls of fire at each other...It doesn't get better than that. Every so often a scroll appears...and the fireballs bounce off walls, or the wizard has rapid fire, or even scrolls of healing! The scroll options are endless. Two bars at the top, each the color of the wizard (with their name beside the bar) indicate how much health they have. Possibly the appearance of the scrolls means the battle is taking too long? I'm thinking 1 player controls: up, down, left, right and space to fire the button. Or even possibly, mouse click and shift - mouse button to fire a spell in the direction they are facing. Two player controls: a, s, d, f and space AND arrows (up, down, left, right) and Del key or Crtl. The game ends when a player has 0 health and a dialog box appears asking for a rematch / reconfigure / exit. Health goes down when a fireball (friendly or not), connects with a wizard. When a wizard connects with a scroll, a countdown clock / icon appears near the health bar and the wizard begins to glow. For the most part, a wizard can have only scroll 1 effect on him at a time. Notes: Ok, there's alot to cover here. a CharacterObject is a GameObject it travels at a set velocity it travels in a direction it has sounds (walking, running, casting, impact, dying, laughing, whistling, other?) it has animations (walking, running, casting, impact, dying, laughing, idle, other?) it has a lifespan (determined by health) it is alive or dead it has a position a ScrollObject is a GameObject it carries a transferance of points "damage" (or healing, bad scroll effect?) (determinde by caster) it carries a transferance of "other" it is stationary it has a sound on impact it has a stationary animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by game) it is alive or dead it has a position a WallObject is a GameObject it has a sound on fireball impact? it is a still image / stationary it has an impact animation / or transfers an impact animation it is dead it has a position A FireBall is a GameObject it carries a transferance of poinst "damage" (or healing, bad scroll effect?) (determinde by caster) it travels at a set velocity it travels in a direction it has a sound it has a travel animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by caster) it is alive or dead it has a position As I look at this, I can see some common attributes in each object that I can carry up to the GameObject. I think I'm going to end the documentation here, it's taken me a bit of time to type this all out, tomorrow. I'll load up my IDE and my paint studio to get some good old fashioned cowboy hacking going!   D.

  • ScrollViewer.EnsureVisible for Windows Phone

    - by Daniel Moth
    In my Translator By Moth app, on both the current and saved pivot pages the need arose to programmatically scroll to the bottom. In the former, case it is when a translation takes place (if the text is too long, I want to scroll to the bottom of the translation so the user can focus on that, and not their input text for translation). In the latter case it was when a new translation is saved (it is added to the bottom of the list, so scrolling is required to make it visible). On both pages a ScrollViewer is used. In my exploration of the APIs through intellisense and msdn I could not find a method that auto scrolled to the bottom. So I hacked together a solution where I added a blank textblock to the bottom of each page (within the ScrollViewer, but above the translated textblock and the saved list) and tried to make it scroll it into view from code. After searching the web I found a little algorithm that did most of what I wanted (sorry, I do not have the reference handy, but thank you whoever it was) that after minor tweaking I turned into an extension method for the ScrollViewer that is very easy to use: this.Scroller.EnsureVisible(this.BlankText); The method itself I share with you here: public static void EnsureVisible(this System.Windows.Controls.ScrollViewer scroller, System.Windows.UIElement uiElem) { System.Diagnostics.Debug.Assert(scroller != null); System.Diagnostics.Debug.Assert(uiElem != null); scroller.UpdateLayout(); double maxScrollPos = scroller.ExtentHeight - scroller.ViewportHeight; double scrollPos = scroller.VerticalOffset - scroller.TransformToVisual(uiElem).Transform(new System.Windows.Point(0, 0)).Y; if (scrollPos > maxScrollPos) scrollPos = maxScrollPos; else if (scrollPos < 0) scrollPos = 0; scroller.ScrollToVerticalOffset(scrollPos); } I am sure there are better ways, but this "worked for me" :-) Comments about this post by Daniel Moth welcome at the original blog.

  • Resultant Vector Algorithm for 2D Collisions

    - by John
    I am making a Pong based game where a puck hits a paddle and bounces off. Both the puck and the paddles are Circles. I came up with an algorithm to calculate the resultant vector of the puck once it meets a paddle. The game seems to function correctly but I'm not entirely sure my algorithm is correct. Here are my variables for the algorithm: Given: velocity = the magnitude of the initial velocity of the puck before the collision x = the x coordinate of the puck y = the y coordinate of the puck moveX = the horizontal speed of the puck moveY = the vertical speed of the puck otherX = the x coordinate of the paddle otherY = the y coordinate of the paddle piece.horizontalMomentum = the horizontal speed of the paddle before it hits the puck piece.verticalMomentum = the vertical speed of the paddle before it hits the puck slope = the direction, in radians, of the puck's velocity distX = the horizontal distance between the center of the puck and the center of the paddle distY = the vertical distance between the center of the puck and the center of the paddle Algorithm solves for: impactAngle = the angle, in radians, of the angle of impact. newSpeedX = the speed of the resultant vector in the X direction newSpeedY = the speed of the resultant vector in the Y direction Here is the code for my algorithm: int otherX = piece.x; int otherY = piece.y; double velocity = Math.sqrt((moveX * moveX) + (moveY * moveY)); double slope = Math.atan(moveX / moveY); int distX = x - otherX; int distY = y - otherY; double impactAngle = Math.atan(distX / distY); double newAngle = impactAngle + slope; int newSpeedX = (int)(velocity * Math.sin(newAngle)) + piece.horizontalMomentum; int newSpeedY = (int)(velocity * Math.cos(newAngle)) + piece.verticalMomentum; for those who are not program savvy here is it simplified: velocity = v(moveX² + moveY²) slope = arctan(moveX / moveY) distX = x - otherX distY = y - otherY impactAngle = arctan(distX / distY) newAngle = impactAngle + slope newSpeedX = velocity * sin(newAngle) + piece.horizontalMomentum newSpeedY = velocity * cos(newAngle) + piece.verticalMomentum My Question: Is this algorithm correct? Is there an easier/simpler way to do what I'm trying to do?

  • Having to check collisions twice per game tic

    - by user22241
    I have vertically moving elevators (3 solid tiles wide) and static solid tiles. Each are separate entities and therefore have their own respective collision routines (to check for, and resolve, collisions with the main character) I check my vertical collisions after characters vertical movements and then horizontal collisions after horizontal movements. The problem is that I want my platform to kill the player if it squashes him from the top, and also if he's on a moving platform (that is moving up) that squashes him into a solid block. Correct behaviour, player on solid blocks being squashed from above by decending elevator Here is what happens. Gravity pushes character into solid block, solid block collision routine corrects characters position and sits him on the solid block which pushes him into the moving elevator, elevator routine then checks for collision and kills player. This assumes I am checking solid blocks first, then elevator collisions. However, if it's the other way around, this happens.... Incorrect behaviour, player on accending elevator gets pushed into solid blocks above Player is on an elevator moving up, gravity pushes him into the elevator, solid block CD routine detects no collision, no action taken. Elevator CD routine detects character has been pushed into elevator by gravity, corrects this by moving character up and sitting him on the elevator and pushes him into the solid blocks above, however the solid block vertical routine has now already run for this tic, so the game continues and the next solid block collision that is encountered is the horizontal routine. This detects a collision and moves the character out of the collision to the left or right of the block which looks odd to say the least (character should get killed here). The only way I've managed to get this working correctly is by running the solid block CD, then the elevator CD, then the solid block CD again straight after. This is clearly wasteful but I can't figure out how else to do this. Any help would be appreciated.

  • Why is Desktop Unity using the global application menu?

    - by Kazade
    It was announced in another question that the desktop version of Unity will keep the global menu by default. Here are the facts: The global menu was introduced into UNE to save vertical screen space because at Netbook resolutions the vertical space is limited. On a modern desktop with a high resolution, there is ample vertical space making this unnecessary On the announcement of UNE global menus, Mark Shuttleworth himself said the following: "There are outstanding questions about the usability of a panel-hosted menu on much larger screens, where the window and the menu could be very far apart." The benefits of a global menu don't seem to carry across to a high-resolution desktop and instead seem to bring draw backs (increased mouse travel, large distance between the menu and its associated window). The other worrying factor is that applications seem to be moving away from having a menu bar, and instead of innovating on this and defining new guidelines for moving away from the menu, we are giving it prime place right at the top of the desktop. If applications continue moving away from the desktop we will have an inconsistent experience concerning where to locate application related options/tools depending on which app you are using (e.g. Chrome). Finally, the current global menu bar implementation doesn't work for all apps, and doesn't even work for all apps in the default install. This means that the default desktop implementation will be inconsistent. So, there are a bunch of reasons why moving to a global menu is a bad idea, so we need some pretty convincing arguments for why it is a good idea. What are the reasons for the global menu implementation in the desktop version of Unity?

  • Center content of UISCrollView when smaller

    - by hgpc
    I have an UIImageView inside a UIScrollView which I use for zooming and scrolling. If the image/content of the scroll view if bigger than the scroll view everything works fine. However, when the image becomes smaller than the scroll view, it sticks to the top left corner of the scroll view. I would like to keep it centered, like the Photos app. Any ideas or examples about keeping the content of the UIScrollView centered when smaller? I am working with iPhone 3.0. The following code almost works. The image returns to the top left corner if I pinch it after reaching the minimum zoom level. - (void)loadView { [super loadView]; // set up main scroll view imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [imageScrollView setBackgroundColor:[UIColor blackColor]]; [imageScrollView setDelegate:self]; [imageScrollView setBouncesZoom:YES]; [[self view] addSubview:imageScrollView]; UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"WeCanDoIt.png"]]; [imageView setTag:ZOOM_VIEW_TAG]; [imageScrollView setContentSize:[imageView frame].size]; [imageScrollView addSubview:imageView]; CGSize imageSize = imageView.image.size; [imageView release]; CGSize maxSize = imageScrollView.frame.size; CGFloat widthRatio = maxSize.width / imageSize.width; CGFloat heightRatio = maxSize.height / imageSize.height; CGFloat initialZoom = (widthRatio heightRatio) ? heightRatio : widthRatio; [imageScrollView setMinimumZoomScale:initialZoom]; [imageScrollView setZoomScale:1]; float topInset = (maxSize.height - imageSize.height) / 2.0; float sideInset = (maxSize.width - imageSize.width) / 2.0; if (topInset < 0.0) topInset = 0.0; if (sideInset < 0.0) sideInset = 0.0; [imageScrollView setContentInset:UIEdgeInsetsMake(topInset, sideInset, -topInset, -sideInset)]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return [imageScrollView viewWithTag:ZOOM_VIEW_TAG]; } /************************************** NOTE **************************************/ /* The following delegate method works around a known bug in zoomToRect:animated: */ /* In the next release after 3.0 this workaround will no longer be necessary */ /**********************************************************************************/ - (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale { [scrollView setZoomScale:scale+0.01 animated:NO]; [scrollView setZoomScale:scale animated:NO]; // END Bug workaround CGSize maxSize = imageScrollView.frame.size; CGSize viewSize = view.frame.size; float topInset = (maxSize.height - viewSize.height) / 2.0; float sideInset = (maxSize.width - viewSize.width) / 2.0; if (topInset < 0.0) topInset = 0.0; if (sideInset < 0.0) sideInset = 0.0; [imageScrollView setContentInset:UIEdgeInsetsMake(topInset, sideInset, -topInset, -sideInset)]; }

  • Help trying to get two-finger scrolling to work on Asus UL80VT

    Multi-touch works fine on Windows 7 with: two-fingers scroll vertical and horizontally, two-finger tap for middle click, and three-finger tap for right click. However with Ubuntu, I've never been able to get multi-touch to "save" and work, I was able to get it to work a few times but after restarting - it would just reset back. I have the settings for two-finger scrolling on: Mouse and Touchpad Touchpad Two-finger scrolling (selected) Enable horizontal scrolling (ticked) The cursor stops moving when I try to scroll with two fingers, but it doesn't actually scroll the page. When I perform xinput list, I get: Virtual core pointer id=2 [master pointer (3)] ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ETPS/2 Elantech ETF0401 id=13 [slave pointer (2)] I've tried to install some 'synaptics-dkms' bug-fix (from a few years back) but that didn't work, so I removed that. I've tried installing 'uTouch' but that didn't seem to do anything so removed it. Here's what I have installed now: dpkg --get-selections installed-software grep 'touch\|mouse\|track\|synapt' installed-software libsoundtouch0 --- install libutouch-evemu1 --- install libutouch-frame1 --- install libutouch-geis1 --- install libutouch-grail1 --- install printer-driver-ptouch --- install ptouch-driver --- install xserver-xorg-input-multitouch --- install xserver-xorg-input-mouse --- install xserver-xorg-input-vmmouse --- install libnetfilter-conntrack3 --- install libxatracker1 --- install xserver-xorg-input-synaptics --- install So, I'll start again, what should I do now to get two-finger scrolling to work and ensure it works after restarting? Also doing: synclient TapButton1=1 TapButton2=2 TapButton3=3 ...works but doesn't save after restarting. However doing: synclient VertTwoFingerScroll=1 HorizTwoFingerScroll=1 Does NOT work to fix the two-finger scrolling.

  • How to Speed Up Any Android Phone By Disabling Animations

    - by Chris Hoffman
    Android phones — and tablets, too — display animations when moving between apps and screens. These animations look very slick, but they waste time — especially on fast phones, which could switch between apps instantly if not for the animations. Disabling these animations will speed up navigating between different apps and interface screens on your phone, saving you time. You can also speed up the animations if you’d rather see them. Access the Developer Options Menu First, we’ll need to access the Developer Options menu. It’s hidden by default so Android users won’t stumble across it unless they’re actually looking for it. To access the Developer Options menu, open the Settings screen, scroll down to the bottom of the list, and tap the About phone or About tablet option. Scroll down to the Build number field and tap it repeatedly. Eventually, you’ll see a message appear saying “You are now a developer!”. The Developer options submenu now appears on the Settings screen. You’ll find it near the bottom of the list, just above the About phone or About tablet option. Disable Interface Animations Open the Developer Options screen and slide the switch at the top of the screen to On. This allows you to change the hidden options on this screen. If you ever want to re-enable the animations and revert your changes, all you have to do is slide the Developer Options switch back to Off. Scroll down to the Drawing section. You’ll find the three options we want here — Window animation scale, Transition animation scale, and Animator duration scale. Tap each option and set it to Animation off to disable the associated animations. If you’d like to speed up the animations without disabling them entirely, select the Animation .5x option instead. If you’re feeling really crazy, you can even select longer animation durations. You can make the animations take as much as ten times longer with the Animation 10x setting. The Animator duration scale option applies to the transition animation that appears when you tap the app drawer button on your home screen.  Your change here won’t take effect immediately — you’ll have to restart Android’s launcher after changing the Animator duration scale setting. To restart Android’s launcher, open the Settings screen, tap Apps, swipe over to the All category, scroll down, and tap the Launcher app. Tap the Force stop button to forcibly close the launcher, then tap your device’s home button to re-launch the launcher. Your app drawer will now open immediately, too. Now whenever you open an app or transition to a new screen, it will pop up as quickly as possible — no waiting for animations and wasting processing power rendering them. How much of a speed improvement you’ll see here depends on your Android device and how fast it is. On our Nexus 4, this change makes many apps appear and become usable instantly if they’re running in the background. If you have a slower device, you may have to wait a moment for apps to be usable. That’s one of the big reasons why Android and other operating systems use animations. Animations help paper over delays that can occur while the operating system loads the app.

  • Android ScrollView Not Scrolling Correctly

    - by user3133534
    I've been making my way through thenewboston's android tutorials and I'm stuck on number 35. There is supposed to be a scroll bar that takes up a weight of 30 at the top of the app. There are 6 textview/edittext field groups in the code, but I deleted 5 for simplicity. My problem is that all of the text and text boxes appear on the page and are not confined to the given weight (they all just show up on the page). Has anyone else had this problem or know how to fix it? Please, I'm new to stackoverflow. If you think this is a stupid question, please explain to me why and how I can ask it better. Here is what it looks like: http://imgur.com/gJmOgqk <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:weightSum="100" > <ScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:layout_weight="30" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView" /> <EditText android:id="@+id/editText1" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" > </EditText> </LinearLayout> </ScrollView> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_weight="40" android:orientation="vertical" > <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_weight="30" android:orientation="vertical" > <AnalogClock android:id="@+id/analogClock1" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> </LinearLayout>

  • Flex chart axis title blinking on resize

    - by Anoop
    I am having a chart with titles for horizontal and vertical axis. the verticalAxisTitleAlignment property of the vertical axis renderer is set to vertical. The application is a portal sort of thing and this chart is placed inside a small window. on click of the window am resizing the parent of the chart. but at that time the title of the axis is blinking and it provides a feeling that the resizing is not smooth. I dont understand why this happens? does the tile renders each time when the component is maximized? is there any way to stop that? Thanks in Advance, Cheers, PK This is the code am using to draw the title : <mx:horizontalAxis> <mx:LinearAxis id="haxis" title="Share" interval="5"/> </mx:horizontalAxis> <mx:verticalAxis> <mx:LinearAxis id="vaxis" title="{'Aided'+ '\n'+ ' awareness'}" interval="5"/> </mx:verticalAxis> <mx:horizontalAxisRenderers> <mx:AxisRenderer axis="{haxis}" axisStroke="{axisStroke}" tickPlacement="none"/> </mx:horizontalAxisRenderers> <mx:verticalAxisRenderers> <mx:AxisRenderer axis="{vaxis}" axisStroke="{axisStroke}" verticalAxisTitleAlignment="vertical" tickPlacement="none"/> </mx:verticalAxisRenderers>

  • problems with scrolling a java TextArea

    - by Jonathan
    All, I am running into an issue using JTextArea and JScrollPane. For some reason the scroll pane appears to not recognize the last line in the document, and will only scroll down to the line before it. The scroll bar does not even change to a state where I can slide it until the lines in the document are two greater than the number of lines the textArea shows (it should happen as soon as it is one greater). Has anyone run into this before? What would be a good solution (I want to avoid having to add an extra 'blank' line to the end of the document, which I would have to remove every time I add a new line)? Here is how I instantiate the TextArea and ScrollPane: JFrame frame = new JFrame("Java Chat Program"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Container pane = frame.getContentPane(); if (!(pane.getLayout() instanceof BorderLayout)) { System.err.println("Error: UI Container does not implement BorderLayout."); System.exit(-1); } textArea = new JTextArea(); textArea.setPreferredSize(new Dimension(500, 100)); textArea.setEditable(false); textArea.setLineWrap(true); textArea.setWrapStyleWord(true); JScrollPane scroller = new JScrollPane(textArea); scroller.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS); pane.add(scroller, BorderLayout.CENTER); Here is the method I use to add a new line to textArea: public void println(String a) { textArea.append(" "+a+"\n"); textArea.setCaretPosition(textArea.getDocument().getLength()); } Thanks for your help, Jonathan EDIT: Also, as a side note, with the current code I have to manually scroll down. I assumed that setCaretPosition(doc.getLength()) in the println(line) method would automatically set the page to the bottom after a line is entered... Should that be the case, or do I need to do something differently?

  • How to make a UITextField move up when keyboard is present

    - by philfreo
    EDIT: Over 1k views with 3 upvotes? If this question is helpful, vote it up :) With the iPhone SDK: I have a UIView with UITextFields that brings up a keyboard. I need it to be able to: Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up Automatically "jump" (by scrolling up) or shortening I know that I need a UIScrollView. I've tried changing the class of my UIView to a UIScrollView but I'm still unable to scroll the textboxes up or down. Do I need both a UIView and a UIScrollView? Does one go inside the other? [EDIT: I now know that you want a UIView inside of a UIScrollView, and the trick is to programatically set the content size of the UIScrollView to the frame size of the UIView.] Then what needs to be implemented in order to automatically scroll to the active text field? Ideally as much of the setup of the components as possible will be done in Interface Builder. I'd like to only write code for what needs it. Note: the UIView (or UIScrollView) that I'm working with is brought up by a tabbar (UITabBar), which needs to function as normal. Edit: I am adding the scroll bar just for when the keyboard comes up. Even though it's not needed, I feel like it provides a better interface because then the user can scroll and change textboxes, for example. I've got it working where I change the frame size of the UIScrollView when the keyboard goes up and down. I'm simply using: -(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height - 215 + 50); //resize } -(void)textFieldDidEndEditing:(UITextField *)textField { //keyboard will hide scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height + 215 - 50); //resize } However this doesn't automatically "move up" or center the lower text fields in the visible area, which is what I would really like.

  • Android: Creating a Scrollable Layout

    - by MD
    I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now. The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application. Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through. I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful. EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)

  • Codeigniter image manipulation class rotates image during resize

    - by someoneinomaha
    I'm using Codeigniter's image manipulation library to re-size an uploaded image to three sizes, small, normal and large. The re-sizing is working great. However, if I'm resizing a vertical image, the library is rotating the image so it's horizontal. These are the config settings I have in place: $this->resize_config['image_library'] = 'gd2'; $this->resize_config['source_image'] = $this->file_data['full_path']; $this->resize_config['maintain_ratio'] = TRUE; // These change based on the type (small, normal, large) $this->resize_config['new_image'] = './uploads/large/'.$this->new_file_name.'.jpg'; $this->resize_config['width'] = 432; $this->resize_config['height'] = 288; I'm not setting the master_dim property because the default it set to auto, which is what I want. My assumption is that the library would take a vertical image, see that the height is greater than the width and translate the height/width config appropriately so the image remains vertical. What is happening (apparently) is that the library is rotating the image when it is vertical and sizing it per the configuration. This is the code in place I have to do the actual re-sizing: log_message('debug', 'attempting '.$size.' photo resize'); $this->CI->load->library('image_lib'); $this->CI->image_lib->initialize($this->resize_config); if ($this->CI->image_lib->resize()) { $return_value = TRUE; log_message('debug', $size.' photo resize successful'); } else { $this->errors[] = $this->CI->image_lib->display_errors(); log_message('debug', $size.' photo resize failed'); } $this->CI->image_lib->clear(); return $return_value;

  • Problem with UIScrollView

    - by leon
    Hi, Sorry for long winded post. I am trying to understand UIScrollView and running into very simple problem. I am creating a scroll view I am making this view 1.5 size larger then normal size Using UIScrollView I expect to see some edge elements of view out of bounds, but should be able to pan the view therefore bringing missing elements back to the visible area. However I am seeing that I can't just pan/scroll view anyway I want, instead view always wants to scroll up, as soon as move away my finger from the screen (touch end event). I am not handling any touches, etc - I just want to understand why does not scaled view stay put where I scroll it? CGRect viewFrame = self.view.frame ; viewFrame.size.width *= 1.5; viewFrame.size.height *= 1.5; CGSize mySize = viewFrame.size; [ ((UIScrollView *) self.view) setContentSize: mySize]; self.view.transform = CGAffineTransformMakeScale(1.5, 1.5); What I really trying to accomplish is something similar to Number on iPad (the same code will work on iPhone): There is a view with lots of controls on it (order entry form) User can zoom into the entire form so all elements look bigger user can pan the form therefore bringing various elements into the visible area of the screen. It seems that UIScrollView can should be able to handle zoom and pan actions (for now I am using Affine Transform to zoom in to the order entry form and iPad) Thanks

  • Scrolling down to next element via keypress & scrollTo plugin - jQuery

    - by lyrae
    I am using jQuery's scrollTo plugin to scroll up and down my page, using UP arrow and DOWN arrow. i have a bunch of div with class "screen", as so: <div class="screen-wrapper">...</div> What I am trying to do is, when i press UP or DOWN, the window scrolls to the next, or previous div with class of "screen". I have the keypresses taken care of. According to the plugin docs, to scroll a window, you use $.scrollTo(...); Here's the code I have: $(document).keypress(function(e){ switch (e.keyCode) { case 40: // down n = $('.screen-wrapper').next() $.scrollTo( n, 800 ); break; case 38: // up break; case 37: // left break; case 39: // right break; } }); And if it helps, here's the HTML div. I have a few of these on the page, and essentially, am trying to scroll to next one by pressing down arrow: <div class='screen-wrapper'> <div class='screen'> <div class="sections"> <ul> <li><img src="images/portfolio/sushii-1.png " /></li> <li><img src="images/portfolio/sushii-2.png" /></li> <li><img src="images/portfolio/sushii-3.png" /></li> </ul> </div> <div class="next"></div> <div class="prev"></div> </div> And also if it needed, I can provide a link where this is being used if it'll help someone get a better idea. edit And, i forgot to mention what the real question here is. The question/problem is that it won't scroll down past the first element, as seth mentioned.

  • Add double tap action (presentModalViewController) to UISCOLLVIEW

    - by R.J.
    I have been wrestling this issue for a while now and cannot seem to get the following "touchesEnded" method to execute within a UISCROLLVIEW. I have read on many of the forums that UISCROLLVIEW will take control of all touch events unless it is subclassed, but I cannot seem to get the code right (still new to the SDK). Basically I have a scrollview made uo with several UIIMAGEVIEW's and currenlty have scrolling with paging (much like the photo app). I have been studying the SCROLLING MADDNESS example without success. All I want to do is anywhere in the UISCROLLVIEW have the user double tap to presentModalViewController back to my info page (i.e.) (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSSet *allTouches = [event allTouches]; switch ([allTouches count]) { case 1: {// One finger touch UITouch *touch = [[allTouches allObjects] objectAtIndex:0]; if ([touch tapCount] == 2) {InfoButtonViewController *scroll = [[InfoButtonViewController alloc] initWithNibName:nil bundle:nil]; scroll.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:scroll animated:YES]; [scroll release]; } } } } Any code assistance would be greatly appreciated. The UISCROLLVIEW is implemented as follows (let me know if I need to provide additional details). Thank you in advance... MyViewController.h @interface MyViewController : UIViewController { } @end

  • QT: custom widget in QScrollArea

    - by slimscsi
    I am attempting to create a custom widget. My Widget renders itself unless it is inside a scroll area. The code below works. If I change the if(0) to an if(1) inside the MainWindow constructor, it will not render the "Hello World" string. I assume that I must (re)implement some additional methods, but so far I have not been able to find the correct ones with trial and error. // hellowidget.h #ifndef HELLOWIDGET_H #define HELLOWIDGET_H #include <QtGui> class HelloWidget : public QWidget { Q_OBJECT public: HelloWidget(QWidget *parent = 0); void paintEvent(QPaintEvent *event); }; #endif // HELLOWIDGET_H // hellowidget.cpp #include "hellowidget.h" HelloWidget::HelloWidget(QWidget *parent) : QWidget(parent) { } void HelloWidget::paintEvent(QPaintEvent *event) { QPainter painter(this); painter.drawText(rect(), Qt::AlignCenter, "Hello World"); } // mainwindow.h #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QtGui> class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0); ~MainWindow(); private: }; #endif // MAINWINDOW_H // mainwindow.cpp #include "mainwindow.h" #include "hellowidget.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { HelloWidget *hello = new HelloWidget; QWidget *central = hello; if( 0 ) { QScrollArea *scroll = new QScrollArea ; scroll->setWidget(hello); central = scroll; } setCentralWidget( central ); } MainWindow::~MainWindow() { } // main.cpp #include <QtGui/QApplication> #include "mainwindow.h" int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w; w.show(); return a.exec(); }

  • jQuery code working in Safari and Chrome but not Firefox

    - by Chris Armstrong
    I'm got a site that has a long list of tweets, and as you scroll down the right column follows you down, showing stats on the tweets. (See it in action at http://www.grapevinegame.com . Click 'memorise', then 'skip' to get to the list page. Works in Safari and Chrome). I'm using jQuery to update the top-margin of the right column, increasing it as I scroll down. It seems to be working fine in webkit-based browsers, but doesn't budge in Firefox. Heres the code, the right column element is a div with id = "distance". // Listen for scroll function $(window).scroll(function () { // Calculating the position of the scrollbar var doc = $("body"), scrollPosition = $("body").scrollTop(), pageSize = $("body").height(), windowSize = $(window).height(), fullScroll = (pageSize) - windowSize; percentageScrolled = (scrollPosition / fullScroll); var entries = $("#whispers-list > li").length; // Set position of distance counter $('div#distance').css('margin-top', ($("#whispers-list").height()+$("#latest-whisper").height()+33)*percentageScrolled); // Update distance counter $('#distance-travelled').text(Math.round(distanceTravelled*(1-percentageScrolled))); $('#whispers-list li').each(function(index) { //highlight adjacent whispers if ($('#whispers-list li:nth-child('+(index+1)+')').offset().top >= $('#distance').offset().top && $('#whispers-list li:nth-child('+(index+1)+')').offset().top <= $('#distance').offset().top + $('#distance').height()) { // alert("yup"); $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 1); } else { $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 0.5); } }); }); Appreciate any help or advice!

  • Automatically grow document view of NSScrollView using auto layout?

    - by Monolo
    Is there a simple way to get an NSScrollView to adapt to its document view changing size when using autolayout (the Lion feature)? I have tried to call both setNeedsUpdateConstraints: and setNeedsLayout: on the document view, the clip view and the scroll view, without any results. fittingSize of the document view reports the correct size. An NSPopover in conjunction with an NSViewController handles this nicely, with the popover growing and shrinking as needed, and I was hoping to get a similar simple and robust behaviour with the scroll view. I have checked the documentation for scroll views, but they don't seem to be updated to use autolayout. Edited to clarify: The problem I experience is that the document view, which holds subviews, is not re-sized when the subviews change their size, even if they call invalidateIntrinsicContentSize. The contents of the document view are hence clipped to the original size of the document view as they grow. The document view is created in a nib and set as the scroll view's document view in an awakeFromBib method. What I hoped to obtain was that the document view frame would automatically be adjusted to when its fittingSize changes, and the scrollbars updated accordingly. NSPopover does something similar - provided that the subviews of the content controller's view have the constraints set right and various content hugging values are high enough (higher than the hidden popover window's hight constraint priority, for one).
