  • Mouse Events lost on zoom in silverlight

    - by Ged
    Hi All, I'm running into an issue where I seem to be losing mouse events. Essentially I have a grid with a bunch of controls that get refreshed (removed/re-added via Grid.Children.Clear and Grid.Children.Add(control) ) via a WCF_Service. If I zoom in to a part of the grid where no control exists, I'm unable to zoom out. I have implemented zoom to mouse position but have logic to ensure the coordinates of the grid are never beyond the window of screen. (Eg: Grid.ActualWidth must be 0 and Translate.X must be < Grid.ActualWidth - 200) I have also experienced this where I can still see a section of one of the controls, but it still is not able to zoom out (unless I'm over the control). Appreciate any and all help.

  • JButtons don't imediatly change on mouse event

    - by out_sider
    I'm using the java swing library to develop a board game called DAO. The problem is that after the human player makes its move, by clicking on the JButton with the piece image that he wants to play, I call the computer AI routine but inside the mouse event function. By doing this only when the function returns, the computer ends its turn, do the JButtons refresh their Images (setIcon comes in). I'd like to know how can I force the JButtons to change their image at the moment they are clicked and not only when the mouse event function ends (as I need to handle data inside it). I've tried all of this myButtons[i][j].setIcon(xIcon); myButtons[i][j].revalidate(); myButtons[i][j].repaint(); myButtons[i][j].validate(); None worked. Thx in advance

  • Laptop + External Monitor: Possible to Scale Mouse-crossover Position?

    - by Brian Lacy
    I have a laptop with a 16" screen @ 1366x768 resolution, and a 24" external monitor at 1920x1200 resolution. I'm extending the Windows 7 desktop onto the other screen. The 24" is the secondary monitor, and is positioned so the bottom of that screen lines up with the bottom of the 16" screen. Currently, if I move the mouse to the top portion of the 24" screen, then move left, the mouse will stop at the edge of the 24" screen until I move it down far enough to get into the range of the 16" screen. So that's all pretty standard; but I'm wondering if there's any software out there that will allow me to "scale" the mouse-crossover position, such that if I'm at the TOP of the 24" screen and move left, the mouse will cross to the TOP of the 16" screen, whereas if I'm at the BOTTOM of the 24" screen, crossing over will position the mouse at the BOTTOM of the 16" screen. So then, if the mouse cursor is on the 24" screen at (x,y) position (10,600), and I move 20 pixels left, the mouse is now on the 16" screen at position (1356,384). Anyone know of such a solution?? Note: I also use Ubuntu, so if there's a solution to this for X, but not Windows, I'd be interested in that also.

  • Graphics Question: How do I restrict the mouse cursor to within a circle?

    - by Dan
    I'm playing with XNA. When I click the left mouse button, I record the X,Y co-ordinates. Keeping the mouse button held down, moving the mouse draws a line from this origin to the current mouse position. I've offset this into the middle of the window. Now, what I'd like to do is restrict the mouse cursor to within a circle (with a radius of N, centred on the middle of the screen). Restricting the mouse to a rectangular region is easy enough (by adjusting the origin by the difference of the mouse position and the size of the region), but I haven't a clue on how to start doing it for a circular region. Can anyone explain how to do this? Any advice on where to start would be helpful.

  • Java keyboard hook

    - by Jason S
    I would like to write a Java app that counts how long I have been using the keyboard or mouse w/o a break. Are there any built-in classes or 3rd party libraries that can detect global keyboard/mouse use?

  • How to reboot/shutdown Windows 8 without the mouse?

    - by Diogo
    Nowadays on Windows 7, if I have no mouse on my computer I just press Win Buttom+-+Enter: This makes my computer to shutdown without using a mouse. However, on Windows 8, I need the mouse to open that hidden menu on the right side of the screen, open the "Settings" tab - "Power" - Then choose for "Shut down", "Sleep" or "Restart": There is some keyboard shortcut to open these shutdowns options on Windows 8 or another way that not just with the mouse pointer?

  • Ubuntu: Copy terminal mouse selection automatically to clipboard for other apps?

    - by mfn
    I can use keyboard shortcuts and selecting text with the left mouse button allows me to insert the selection within gnome-terminal with the middle mouse button. However, mouse selection with left button does not copy it to the clipboard and thus is not available to other apps. I don't want to use the keyboard shortcuts when I select text with the left mouse button, I want to automatically have it in the clipboard (much like putty works on Windows).

  • Cursor moves when left or right clicking on trackpad

    - by n00b
    I'm on an acer aspire v5-572p. When I am using the touchpad, and I left or right click something, the cursor moves every time by a couple pixels because unfortunately the clicking area, is also a touch area. I've tried switching to the synaptics mouse drivers provided on the Acer driver website, but the same problem exist. I have researched this problem and there is a fix for this issue in Ubuntu, but I am running Windows 8.1 x64. The problem also existed when I was on 8.0 How do I stop the cursor from moving on a click?

  • interesting uses for a headless host running Ubuntu.

    - by Manuel
    Hey! So, I have configured a pc with no monitor, keyboard or mouse running Ubuntu. I use it as a ssh server, file backup, web server, etc. Though, it seems as if I could use it for sooo much more. The problem is I can't think of many more uses. What interesting uses of a headless host have you heard of? Is there a cool trick you want to share? Thanks! Manuel

  • Looking for a USB A/B Box

    - by Kaji
    I have a laptop and a tower, and I usually like to use the laptop for my chat and other miscellaneous tasks while the tower is doing the hard work during video editing projects and such. Due to the way my desk is set up, it's kind of a stretch to reach over to the laptop's keyboard all the time, and having a second keyboard/mouse is rather cumbersome, albeit manageable if I keep the second keyboard in my lap. Does anyone make an A/B box that I can plug into the tower and the laptop so I can just flip the keyboard over to the appropriate machine as needed?

  • Linux Mint loses Window Focus

    - by Chris
    I recently installed Linux Mint 13 64bit with Cinamon Desktop and run into a weird problem. It's about losing Mouse-Focus if more than one Window are open. For Example, I open up Chromium, play around a little bit, and then, if I try to open any Programms from the Taskbar, I cannot click on it. It seems that Chromium won't free his Focus. Another Example, if I open two Windows (e.g. Chromium and a Terminal) and I work with Chromium, then click into the Terminal I get no Focus to it. Sorry, its a bit hard to explain.

  • Certain running applications cause middle-click in firefox to function differently under windows 7

    - by Charlie
    If I have photoshop, vlc player, or even just the windows task list open, when I middle click in firefox to get it to open in new tab (by depressing both buttons on my Lenovo g550 with alps touchpad), the mouse icon changes to some variety of scroll type feature, middle click doesn't work, and if I persist then the other programs take focus, and some crash. I assume the scroll like feature must be intended as added functionality in either windows 7 or the alps touchpad driver, but no settings adjustments seem to be able to remove this, and I could see nothing regarding this in firefox. I would really like to fix this! Thanks.

  • How do I make control-click in Opera open new tabs?

    - by user21952-is-a-great-name
    Update: As of version 11.50, control-click opens the new tab in background, as desired. Yay! In Opera, as opposed to all other modern browsers I know, control-click does not open a new tab. Moreover, I couldn't find any good way to configure this behavior. The best available option seems to be this. However, it's so hacky that it won't work on HTTPS sites unless you enable user javascript there, which doesn't seem like a good idea. There also seem to be other proposed solutions, but none of them seem to work. I'd like this because my laptop has no middle mouse-button, and I'm a creature of habit. Do people have any ideas (for the latest version, 10.50)? I'd like ctrl-click to open a background tab, but I can do with foreground. Thank you!

  • How to Disable Touchpad tap in Toshiba Tecra R850 in Oneiric - it is recognized as a PS/2 mouse

    - by Kibi
    I know there's a lot of similar questions, but nothing I have tried here works yet - perhaps I was doing it wrong. New Laptop - Toshiba Tecra R850 with an install of Oneiric 64 bit. Mostly things are working well, but I have a problem with the touchpad (or whatever it's called) - whenever I use it for moving the mouse pointer I accidentally tap on it - basically I am clicking all over the place by accident. So I want to disable the tap-as-click (after all, I have buttons for clicks too). I open up "Mouse and Touchpad" and on the Touchpad tab I check "Disable touchpad when typing" and UNcheck "Enable mouse clicks with touchpad". This does not achieve anything. Ditto Synaptiks and other similar tools. EDIT OK it turns out that this is a somewhat known problem - it seems the touchpad is not being recognized as a touchpad, it is seen as a PS/2 mouse. So any adjustments made with various settings programs to the "touchpad" don't affect it. I've been looking at solutions for getting the touchpad correctly recognized and not achieved it yet - seems there is a problem at the kernel level...I tried (foolishly) a suggestion to replace the psmouse.ko driver ...this screwed some stuff up and didn't solve my problem. So - anyone know an answer? Thanks Kibi

  • converting 2D mouse coordinates to 3D space in OpenGL ES

    - by Jayesh
    I want to convert mouse's current X and Y coordinates into the 3D space I have drawn in the viewport. I need to do this on the OpenGL ES platform. I found following possible solutions implemented in OpenGL, but none fits what I am looking for. I found NeHe's tutorial on doing exactly this, but in traditional OpenGL way. It uses gluUnProject. http://nehe.gamedev.net/data/articles/article.asp?article=13 Although gluUnProject is not available in OpenGL ES, its implementation seems simple enough to port back. But before calling it, we need to call glReadPixels with GL_DEPTH_COMPONENT and that is not possible in OpenGL ES. (The reason I found in this thread: http://www.khronos.org/message_boards/viewtopic.php?f=4&t=771) What I want to do is similar to picking, except that I don't want to select the object but I want exact coordinates so that I can recognize particular portion of the object that is currently under mouse cursor. I went through the Picking tutorials in this answer. http://stackoverflow.com/posts/2211312/revisions But they need glRenderMode, which I believe is absent in OpenGL ES. If you know how to solve this problem in OpenGL ES, please let me know. Thanks.

  • Flex HTMLLoader component not raising mouseDown events for all mouse clicks

    - by shane
    I have built a Air 2/Flex 4 kiosk application with Flash Builder 4. Currently I am implementing a touch screen browser to enable users to navigate company training videos. In an attempt to improve the usability of the website on the touchscreen I have placed the HTML component in an adaption of Doug McCune's DragScrollingCanvas (updated to use the flex 4 'Scroller' component) to allow users to scroll the webpage by dragging their finger across the screen. The mouseDown event is used to start scrolling the viewport. In addition the webpage was modified to disable text selection with the following css: html { -webkit-user-select: none; cursor: default; } The problem I face is that the HTMLLoader component only fires a mouseDown if a link/input/button on the webpage is clicked, not when the background or any text is clicked. In addition if I remove the custom css the mouseDown event will not fire when text is being selected, but will if previously highlighted text is clicked. As an alternative I also tried adding a group container with the same dimensions as the HTMLLoader to detect the mouseDown events (so that the group container and HTMLLoader have the same Dragable parent container) and was able to capture mouseDown events and scroll the viewport as expected. However as the mouse event is handled by the group container, I am now unable to navigate the webpage. Does anybody know why the HTMLLoader component is not raising mouseDown events for all mouse clicks?

  • Capturing mouse events for specific dom/web elements in QT

    - by Red Serpent
    Hi I would like to know if it is possible in QTWebKit to install an event filter or capture events that occur from specific Dom elements. For example, my webview is showing a webpage that has text, images and an edit box, I want to disable the right-clicking and highlighting functionality on the text and images but at the same time when the user right-clicks inside the edit box, I want to display my context menu. I am not sure where should I install my event filter, in QwebView or QwebPage... currently this is what I'm using: MainWindow::MainWindow() { centralWidget = new WebView(this); setCentralWidget(centralWidget); centralWidget->webView->installEventFilter(this); //No mouse events are rising on QWebPage //centralWidget->webView->page()->installEventFilter(this); } As its clear in the code above, when installing an EventFilter on QwebPage, I never receive any QMouseEvents, not by moving clicking or releasing any mouse buttons. While when setting it to filter events from QWebView it works fine. I am really interested with the first part of my question as to how handle Dom elements differently. How can I achieve such goal? Regards
