  • How can I fix a shaky touchpad cursor in Ubuntu on my hp pavilion laptop?

    - by Vindiggity
    I recently installed Ubuntu 12.04 on my laptop and it works great, except after the initial reboot my touchpad cursor shakes violently when I hold my finger completely still on the pad.It works fine with a regular mouse plugged in. I couldn't find much scouting around the internet except that it might be that my touchpad doesn't have any dead zones? I am very new to Ubuntu and am fairly computer savvy, but I don't know a lot about using the terminal or anything like that, so if you could dumb down a fix for this as much as possible for me, I'd greatly appreciate it.

  • Problems with input and suspend(separately)

    - by VaultPrisoner
    I'm still very new at Ubuntu/any other linux OS, so this might be an easy fix for most. I installed Ubuntu 14.04 a few days ago, it's dual-booted with Windows 8.1 and I'm using a Toshiba laptop. Whenever I suspend/close my computer, and then open it again, the front LEDs will light up telling me that it's running, but the screen will not do anything. I can hear the fan spinning, but it's almost like the screen doesn't power on like it should. Also, another problem I'm having, is that ~60% of the time, my trackpad and keyboard do not work at all, this starts as soon as Ubuntu boots up. To fix it, I just turn it off and back on until it works. My USB mouse does work no matter what though. Both problems are only present in Ubuntu and not windows 8.1.

  • Scite Lua - escaping right bracket in regex?

    - by ~sd-imi
    Hi all, Bumped into a somewhat weird problem... I want to turn the string: a\left(b_{d}\right) into a \left( b_{d} \right) in Scite using a Lua script. So, I made the following Lua script for Scite: function SpaceTexEquations() editor:BeginUndoAction() local sel = editor:GetSelText() local cln3 = string.gsub(sel, "\\left(", " \\left( ") local cln4 = string.gsub(cln3, "\\right)", " \\right) ") editor:ReplaceSel(cln4) editor:EndUndoAction() end The cln3 line works fine, however, cln4 crashes with: /home/user/sciteLuaFunctions.lua:49: invalid pattern capture >Lua: error occurred while processing command I think this is because bracket characters () are reserved characters in Lua; but then, how come the cln3 line works without escaping? By the way I also tried: -- using backslash \ as escape char: local cln4 = string.gsub(cln3, "\\right\)", " \\right) ") -- crashes all the same -- using percentage sign % as escape chare local cln4 = string.gsub(cln3, "\\right%)", " \\right) ") -- does not crash, but does not match either Could anyone tell me what would be the correct way to do this? Thanks, Cheers!

  • button inside table view cell shows highlighted state on tapping on cell

    - by Vivek Dandage
    Hi there! I have an issue with the background image of button which is dependent of button state. I have a button inside customized table view cell and i have set different images for button's different states. Please look into the code below. [btnNow setImage:[UIImage imageNamed:@"now_norm.png"] forState:UIControlStateNormal]; [btnNow setImage:[UIImage imageNamed:@"now_focus.png"] forState:UIControlStateHighlighted]; Whenever i tap on the actual button this works great but if i tap on area outside of button but which is still inside that same cell then this button changes its background image from UIControlStateNormal to UIControlStateHighlighted. If i remove background image from UIControlStateHighlighted state then this issue doesn't exists but i need pressed state of the button. Please help me out. Thanks in advance! Vivek Dandage.

  • Mismatched coordinate systems in LWJGL with Mouse and Textures

    - by Braains
    I'm not really sure how to expand on this other than to say that it appears that my LWJGL seems to have different coordinate systems for the Mouse and for painting Textures. It seems that Textures have the usual Java2D way of putting (0, 0) in the upper-left corner, while the Mouse goes by the more sensible way of having the origin in the lower-left corner. I've checked my code a bunch but I don't see anything modifying the values between where I read them and where I use them. It's thrown me for a loop and I can't quite figure it out. I'll post all the code that involves the Mouse input and Texture painting for you guys to look at. private static void pollHelpers() { while(Mouse.next()) { InputHelper.acceptMouseInput(Mouse.getEventButton(), Mouse.getEventX(), Mouse.getEventY()); } while (Keyboard.next()) { if (Keyboard.getEventKeyState()) { InputHelper.acceptKeyboardInput(Keyboard.getEventKey(), true); } else { InputHelper.acceptKeyboardInput(Keyboard.getEventKey(), false); } } } public static void acceptMouseInput(int mouseButton, int x, int y) { for(InputHelper ie: InputHelper.instances) { if(ie.checkRectangle(x, y)) { ie.sendMouseInputToParent(mouseButton); } } } private void sendMouseInputToParent(int mouseButton) { parent.onClick(mouseButton); } public boolean checkRectangle(int x, int y) { //y = InputManager.HEIGHT - y; See below for explanation return x > parent.getX() && x < parent.getX() + parent.getWidth() && y > parent.getY() && y < parent.getY() + parent.getHeight(); } I put this line of code in because it temporarily fixed the coordinate system problem. However, I want to have my code to be as independent as possible so I want to remove as much reliance on other classes as possible. These are the only methods that touch the Mouse input, and as far as I can tell none of them change anything so all is good here. Now for the Texture methods: public void draw() { if(!clicked || deactivatedImage == null) { activatedImage.bind(); glBegin(GL_QUADS); { DrawHelper.drawGLQuad(activatedImage, x, y, width, height); } glEnd(); } else { deactivatedImage.bind(); glBegin(GL_QUADS); { DrawHelper.drawGLQuad(deactivatedImage, x, y, width, height); } glEnd(); } } public static void drawGLQuad(Texture texture, float x, float y, float width, float height) { glTexCoord2f(x, y); glVertex2f(x, y); glTexCoord2f(x, y + texture.getHeight()); glVertex2f(x, y + height); glTexCoord2f(x + texture.getWidth(), y + texture.getHeight()); glVertex2f(x + width, y +height); glTexCoord2f(x + texture.getWidth(), y); glVertex2f(x + width, y); } I'll be honest, I do not have the faintest clue as to what is really happening in this method but I was able to put it together on my own and get it to work. my guess is that this is where the problem is. Thanks for any help!

  • Making an owner-draw button transparent against its arbitrary background in WINCE

    - by EndsOfInvention
    Hi I am trying to place an owner-draw button transparently onto a background. I have no trouble doing this when the background is a solid colour but if the background is an image I cannot seem to get the correct HDC (handle to device context) to Bitblt() the area that button covers. The HDC that is passed as part of the DRAWITEMSTRUCT gives me a button-default-grey area. If I attempt to get the parent of the HWND and then the device context of that i.e pdc = GetDC(GetParent(hWnd)); then the background that gets BitBlt'd is the background of the last painted window. I hope this question makes sense. this is the code I have: pdis = (LPDRAWITEMSTRUCT)(lParam); hdc = pdis->hDC; button = pdis->CtlID - IDC_BUTOFFSET; //pdc = GetDC((hWnd)); pdc = GetDC(GetParent(hWnd)); hbm = CreateCompatibleBitmap(pdc, Buttons_[button]->bc.Size.cx, Buttons_[button]->bc.Size.cy); SelectObject(hdc, hbm); BitBlt(hdc, 0, 0, Buttons_[button]->bc.Size.cx, Buttons_[button]->bc.Size.cy, pdc, Buttons_[button]->bc.Position.x, Buttons_[button]->bc.Position.y, SRCCOPY); TIA Best regards Ends

  • Multiple jQuery UI buttons with same ID

    - by Mark Nolan
    There might be a really simple solution to this question, but i just don't see it! I have a page with a list of items. every item has the same jquery ui button (its inside a dialog and adds that item to a list). i identify the item via the parenting DIV holding the DB id. So far so good... The Problem is only the first button on the list works! The second, third etc. buttons don't show any reaction at all. The buttons all have the same id - as the list is dynamic and the same action is triggered with every click. Only the parenting ID changes. Heres the display part: <div id="2"> <div id="56"> <button id="add-audio-file" class="ui-button ui-state-default ui-corner-all">betty_2.mp3</button> </div> </div> <div id="2"> <div id="57"> <button id="add-audio-file" class="ui-button ui-state-default ui-corner-all">betty_3.mp3</button> </div> </div> And here comes the js Part: $('#add-audio-file').click(function() { assetID = $(this).parent('div').attr('id'); pageID = $(this).parent('div').parent('div').attr('id'); $.post( "modules/portfolio/serialize.php", {id : pageID, assetid : assetID, do : "add-audio-file"}, function(data, textStatus, xhr) { $('#dialog-add-audio').dialog('close'); } ); }); I am using jquery 1.4.2 and jquery ui 1.8rc3 Any ideas?

  • applying css to dijit button

    - by peirix
    I have the following HTML and CSS: <button id="myBtn" dojoType="dijit.form.Button">Testing</button> #myBtn { margin-left: 100px; } The CSS is supposed to push the button in 100px. But since dijit applies some extra layers of HTML around the button, the button gets a 100px padding. JSbin to show the problem edit: Found one (not IE6-compatible) solution: [widgetid=myBtn] { margin-left: 100px; }

  • Cant display button on specific rows of UITableView properly for iPhone

    - by varunwg
    Hi, I am trying to have a button for selected rows of my table. Here is the example code I am using: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *ControlRowIdentifier = @"ControlRowIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:ControlRowIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:ControlRowIdentifier] autorelease]; } if ([indexPath row] > 5) { UIImage *buttonUpImage = [UIImage imageNamed:@"button_up.png"]; UIImage *buttonDownImage = [UIImage imageNamed:@"button_down.png"]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0.0, 0.0, buttonUpImage.size.width, buttonUpImage.size.height); [button setBackgroundImage:buttonUpImage forState:UIControlStateNormal]; [button setBackgroundImage:buttonDownImage forState:UIControlStateHighlighted]; [button setTitle:@"Tap" forState:UIControlStateNormal]; [button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside]; cell.accessoryView = button; } NSUInteger row = [indexPath row]; NSString *rowTitle = [list objectAtIndex:row]; cell.textLabel.text = rowTitle; return cell; } This code works absolutely fine when loaded for 1st time. So, as per the logic it shows 'Tap' button for all rows greater than 5. Problem occurs when I scroll up and down. Once I do that it just starts putting that button at any random row. I dont understand why it does that and it'll be really helpful if someone can give some tips on this. Thanks.

That should get executed and then the button should be disabled

  • Magento - Add a button to system.xml with method attached to it

    - by vrnet
    Hi, I have created a module that has an "export like" method running regularly as defined in my module's cron area of the config.xml file. But I'd like to give the user the ability to run this export method on demand by adding a "Run now" button in the system configuration, thus using the system.xml file. It seems that the "frontend type" button may be working as I've tried and it adds a tiny clickable button in the config section. But I am not able to attach a method nor a label on the button itself. I thought about adding a button in the "Grid.php" file of the module but this not what I'd like to do as it does fit with my acl. Below is my system.xml file with the "button" frontend type. Does anyone have a clue on how to : add a label/value to the button add a class to the button add a method to call when the button is clicked Many thanks for your help ! <?xml version="1.0" encoding="UTF-8"?> <config> ... <fields> ... <run translate="label"> <label>Run now</label> <frontend_type>button</frontend_type> <backend_model>SOME BACKEND MODEL</backend_model> <sort_order>20</sort_order> <show_in_default>1</show_in_default> <show_in_website>1</show_in_website> <show_in_store>1</show_in_store> </run> </fields> ... </config>

  • Floating an inline element to the right of a div

    - by Rajat
    I want to right-align an inline element to the right of a div. I have seen float="right" applied on a span to right align it but it seems semantically incorrect to me as floats are supposed to move "boxes" or block elements to the right or left of a container element. Is my understanding of Float wrong or is there another way of right-aligning inline elements in a container DIV.

  • Enabling all buttons in a repeater except for the clicked one

    - by NewAmbition
    I have a Repeater Control with various buttons in it. When the button gets clicked, it needs to disable itself so it cant be clicked again. Working. However, when I click that button, it needs to enable any other button but it. So, When I click on it, it needs to disable. When I click on another one, the previous button must enable, and that one must disable. So for I've tried: Button btnLoad = (Button)e.Item.FindControl("btnLoad"); foreach (Button b in e.Item.Controls.OfType<Button>().Select(c => c).Where(b => b != btnLoad)) { b.Enabled = true; } btnLoad.Text = "Currently Viewing"; btnLoad.Enabled = false; But it isnt working. Depending on where I put it, its either leaving all the buttons enabled (But still changing its text), or not doing anything at all. What do I need to do to make this work?

  • Beginner Scoring program button development in Java [migrated]

    - by A.G.
    I'm trying to add a "green team" to an example scoring GUI I found online. For some reason, the code compiles, but it runs with only the original two teams. I've tried playing around with the sizes/locations somewhat clumsily, and since no change was observed with these modications (NO change at ALL), I admit that I must be missing some necessary property or something. Any help? Here's the code: import javax.swing.*; import java.awt.Color; import java.awt.event.ActionListener; import java.awt.event.ActionEvent; public class ButtonDemo_Extended3 implements ActionListener{ // Definition of global values and items that are part of the GUI. int redScoreAmount = 0; int blueScoreAmount = 0; int greenScoreAmount = 0; JPanel titlePanel, scorePanel, buttonPanel; JLabel redLabel, blueLabel,greenLabel, redScore, blueScore, greenScore; JButton redButton, blueButton, greenButton,resetButton; public JPanel createContentPane (){ // We create a bottom JPanel to place everything on.

    Basically I'm looking for an application. I know it's slightly off topic, but I'm looking for it to record a series of tutorials for a program I wrote. It's important to show the actions like mouse click, mouse right click, and all what's coming out from the keyboard. In the similar way to this video http://www.flickr.com/photos/jannis/3246408003/ which is made using OSX and ScreenFlick http://www.araelium.com/screenflick/ Is there such an option? Thanks

  • Will not POST with a USB mouse or keyboard plugged in

    - by Thomas O
    I have an Abit KN9 motherboard, and a USB keyboard and mouse. The computer will not POST with the keyboard or mouse plugged in, but they can be used (and they are fully functional) if you plug them in later, after POST. On the POST side of things, it hangs when it shows the installed processor, and goes no further - pressing DEL to go to setup will not work. I've tried disabling legacy USB support as recommended, but can't find the option anywhere in the BIOS.
