  • Does UIScrollView have a special content view for making the scrolling possible?

    - by mystify
    I wonder if UIScrollView has got an "hidden" subview acting as an container for the content. If I scroll a scroll view, is that content view moved up/down in the scroll view? Or is the scrolling offset applied to the bounds of that UIScrollView instance? Or: Does UIScrollView use an additional view as container, or is all content added directly to the view? The documentation doesn't tell much about wether it has a content container or not.

  • enable all touchpad functions

    - by user118136
    When I had been using Windows 8 my touchpad had multiple gestures: 2 fingers direction top-bottom = vertical revers scrolling(if I scrolled top than page have scrolled bottom); 2 finger direction left-right = horizontal revers scrolling zoom in and zoom out like smartphones with 2 fingers 2 finger rotation = rotate image in image viewer (+ 90 deg or -90 deg) place a finger in the left edge and drag it to right = change windows application, in Ubuntu I want to change the active program to left like Ctrl+Shift+Tab place a finger in the right edge and drag it to left = open right menu and select the option moving finger on direction top-bottom, in Ubuntu I want to change the active program to right like Alt+Tab I succeed enable 2 finger vertical scrolling of System Setings, but I want that it do not work in revers sense. Do it exist a method to enable the rest of gestures and revers the vertical scrolling? edit: It's a Synaptics touchpad.

  • How can I set `less` or `more` max lines (scrollable height) limit/boundary in linux?

    - by Rudie
    (Sorry for the title. Any suggestions?) I've set my commandline PS1 to cover 3 lines: white space user, server and pwd $ or # to input I think less (or more?) is configured to break after window's height - 1, because when I do a $ git log, the first two lines are invisible at the top of the window and the rest is scrollable. I'm not sure who handles this scrolling and its configuration, but I assume GIT uses less/more. Where can I configure that my scrollable window is window height - 3 lines and not window height - 1? More info: If I cat lines.txt | less with a 23 line file, it shows the entire file and no scrolling. If I do the same with a 24 line file, it doesn't show line 1 (and no scrolling). With 25 lines: doesn't show lines 1 and 2 (and no scrolling). With 26 lines: shows line 1 and scrolling! The less breakpoint is at the wrong height...

  • WiX built-in WixUI Dialog Sets have horizontal lines that are just a little too short (picture inclu

    - by Coder7862396
    I am creating an installer for my program using WiX (Windows Installer XML). I have used the following code to begin using the built-in WixUI Dialog Sets: <Product ...> <UIRef Id="WixUI_FeatureTree" /> </Product> This, however, creates a dialog set with horizontal lines that are just a little bit too short on every dialog as shown here: I understand that I could create my own set of dialogs to use instead by using software such as SharpSetup and WixEdit but I like the dialogs that WiX creates and only want to make a very small change to them. Is my best option to download the WiX source code and try to modify it? Is there a more simple solution? Perhaps I should contact the developers of WiX to list it as a bug? Maybe they like it that way though. I however think it looks out of place and would like to change it. I am using the latest weekly release of WiX 3.5.

  • How to make header row of a table (with horizontal and vertical scrollers) fixed ?

    - by understack
    I've this sample table and I want to make header row of table visible all the time. Header row should scroll with horizontal scrollbar and shouldn't scroll with vertical scrollbar. table: <div style="width:800px; height:150px;overflow:scroll;margin:50px auto;"> <table style="width:1600px" border="1"> <thead style=""> <tr> <th style="width:800px">id_1</th> <th style="width:800px">id_2</th> </tr> </thead> <tbody style=""> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> </tbody> </table> </div> How can I do this with css only? Suggestions in this and this thread didn't seem to work, possibly due to presence of scrollbars.

  • How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

    - by bentsai
    I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?

  • How can I create an HTML text field that has scrolling background images before it is clicked?

    - by Jeffrey
    I'm looking to add a textbox on my website that captures a single email address. Behind it, I would like a scrolling (or sliding) images to be a "hint" for what the field should be. Example: http://steamboat.com/ - the "Newsletter sign up" toward the top of the page. I can find plenty of jQuery plugins that provide a plain text "hint". Where should I start looking to add this additional affect. Note: I do not want to add any flash elements on the page.

  • How to increse performance of raster scrolling on Mac ?

    - by Max
    I have a game with a big raster map Now we are using jpeg (4900x4200) And durring the game we need to scroll through this map. We use the following: Class Map extends mx.containers.Canvas and mx.controls.Image on it In constructor we have: public function Map() { super(); image.source = ResourceManager.interactiveManager.map;//big image addChild(image); ...... } for scrolling we are use: if(parentAsCanvas==null){ parentAsCanvas = (parent as Canvas); } parentAsCanvas.verticalScrollPosition = newX; parentAsCanvas.horizontalScrollPosition = newY; In windows, we have very good performance. In Linux and Mac in flashplayer we have a good performance too. But in browsers performance is quite slow! What can we do to resolve it?

  • Mouse Wheel Scroll - How can I capture the time interval between start and stop of scrolling?

    - by Rahat
    Is there any way to capture the time interval between mouse wheel scroll start and stop? Actually I want to capture the interval between the scrolling start and stop when I very quickly scroll the mouse wheel. I have already looked at MouseWheel event but it don't fulfill my requirement. In senes that it always gives a value of Delta 120 or -120 but i want to call a function depending on the speed of the mouse scroll for example when i scroll the mouse normally i want to perform function 1 and when i scrolled the mouse very quickly i want to perform the function 2. In other words is there any way to distinguish between the mouse scroll high and normal speed. Any advice will be appreciated.

Here is the JS that I have in the head of my html: <script src="js/jquery-1.2.6.min.js" type="text/javascript" charset="utf-8"></script> <script type="text/javascript" charset="utf-8"> $(function(){ $("#page-wrap").wrapInner("<table><tr>"); $(".post").wrap("<td>"); });</script> There is also of course the other script file, but its huge so I'm not going to post it here.

  • UITableView with dynamic cell heights -- what do I need to do to fix scrolling down?

    - by Ian Terrell
    I am building a teensy tiny little Twitter client on the iPhone. Naturally, I'm displaying the tweets in a UITableView, and they are of course of varying lengths. I'm dynamically changing the height of the cell based on the text quite fine: - (CGFloat)heightForTweetCellWithString:(NSString *)text { CGFloat height = Buffer + [text sizeWithFont:Font constrainedToSize:Size lineBreakMode:LineBreakMode].height; return MAX(height, MinHeight); } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { NSString *text = // get tweet text for this indexpath return [self heightForTweetCellWithString:text]; } } I'm displaying the actual tweet cell using the algorithm in the PragProg book: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TweetCell"; TweetCell *cell = (TweetCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [self createNewTweetCellFromNib]; } cell.tweet.text = // tweet text // set other labels, etc return cell; } When I boot up, all the tweets visible display just fine. However, when I scroll down, the tweets below are quite mussed up -- it appears that once a cell has scrolled off the screen, the cell height for the one above it gets resized to be larger than it should be, and obscures part of the cell below it. When the cell reaches the top of the view, it resets itself and renders properly. Scrolling up presents no difficulties. Here is a video that shows this in action: http://screencast.com/t/rqwD9tpdltd I've tried quite a bit already: resizing the cell's frame on creation, using different identifiers for cells with different heights (i.e. [NSString stringWithFormat:@"Identifier%d", rowHeight]), changing properties in Interface Builder... If there are additional code snippets I can post, please let me know. Thanks in advance for your help!

  • How to know which image is being viewed in UIScrollView? Also, is it possible to loop scrolling for

    - by bruin
    This is what I'm trying to do, and I'm not sure if it's possible using UIScrollView. First, I don't care about zooming, all I care is that the user is able to scroll through images just like the Photo App, this I got. But how do I know which image he is viewing while using UIScrollView? For instance, if he stops on the 3rd image out of 10 images in the view, how do I know he's on that image? I can't find a way to access the index (is this accessible)?? Also, bonus question, once the user scrolls to the last image, I don't want the scrolling to stop but I want it to loop so that image 1 comes after image 10. And vice versa, if you scroll left passed image 1, you'll see image 10. I'm not asking for the logic, I can do this in an array very simply, I just don't know how to access (if it's even possible) the indexing of the images in the scroll view. If it's not, does anyone have a solution to do this? thanks in advance!

  • How to make div follow scrolling smoothly with jQuery?

    - by Martti Laine
    Hello I'm creating a blog layout, which has an sidebar. In sidebar there are sections/boxes, but the last one of these boxes should follow scrolling when none of the other boxes are visible. So, when user scrolls down, he sees a normal sidebar, but when user has went down enough, sidebar ends but the last box starts to follow on the top of the screen. I have seen this a lot on different kind of sites. So hard to explain with my english. I already made it to follow screen smoothly with animate() but couldn't get it like this. Hope you understood. I already tried in Google for almost an hour but couldn't figure out any keywords (due to my bad english). EDIT: My code at the moment: $(window).scroll(function(){ $.each($('.follow-scroll'),function(){ var eloffset = $(this).offset(); var windowpos = $(window).scrollTop(); if(windowpos<eloffset.top) { var finaldestination = 0; } else { var finaldestination = windowpos; } $(this).stop().animate({'top':finaldestination},200); }); });

  • How do I make a full screen scrolling messagebox or window?

    - by chobo2
    Hi First let me start of saying I know absolutely nothing about c++ and I am really just more interested in getting this to work then learning c++(I got enough on my plate to learn). So basically I am trying to make a terms of service for my windows mobile 6 professional application but it seems I need to use c++ to do it. After hours of searching I found a solution but it developed for windows mobile standard. So they somehow used c++ to make a message box and on standard devices(ie non touch screen phones) the message box can have like scrolling. For some reason this is not the case with professional devices(touch screen devices). So my message box goes off the page and you can never accept or decline the terms. So your stuck and on the screen forever till you do some sort of soft restart. http://www.mobilepractices.com/2008/10/setupdll-sample-and-walkthrough-terms.html The above link is the tutorial but here is the actual file that seems to display the message. #include "stdafx.h" #include "ce_setup.h" // This is a variable containing the text to be displayed // in the Terms & Conditions dialog TCHAR Message[] = _T("TERMS & CONDITIONS\r\n ") _T("Selecting YES you're accepting our terms & conditions.\r\n") _T("This is just a sample application.\r\n") _T("From http://www.mobilepractices.com\r\n") _T("You can replace this text with your own.\r\n") _T("We're using a setup.dll to show this dialog.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Last line.\r\n") ; // This function will be called when the user // tries to install the cab. According to its return // value the installation continues or is cancelled. // As this could be called more than once // (i.e. if there is not enough space on the target) // we should take care about fFirstCall parameter // to show the dialog only once. codeINSTALL_INIT Install_Init( HWND hwndParent, BOOL fFirstCall, BOOL fPreviouslyInstalled, LPCTSTR pszInstallDir ) { if (!fFirstCall || ::MessageBoxW(0, Message, _T("SplashScreenSample") , MB_YESNO) == IDYES) return codeINSTALL_INIT_CONTINUE; else return codeINSTALL_INIT_CANCEL; } So I want to change this to something that can scroll. Can I use like a panel control since I know what has scroll or something else? Thanks

  • How to get Mac OS X Terminal.app and screen/vim scrolling to play nice?

    - by rustychains
    OSX 10.6.3 Terminal.app Am a pretty dedicated screen user. Terminal.app line buffer and/or scroll does not seem to work for me. That is while in screen anything that goes past the top of the frame is gone, can't scroll back to. This seems to work ok in other terminal apps gnome, cygwin. Perhaps this is a shell env, config, or command? .screenrc: startup_message off autodetach on shell -$SHELL vbell off defutf8 on caption always caption string "%{= wk}%w" I have tried using defscrollback here with different values, but doesn't have an effect. some .bashrc settings: set -o physical export TERM=xterm-color shopt -s checkwinsize
