  • Why won't my control accept keyboard input?

    - by Mason Wheeler
    I've built a custom control that I'm trying to send input to. It will accept mouse input and report MouseDown, MouseMove and MouseUp correctly, but for whatever reason, it won't accept keyboard input. When I click on it, it doesn't receive focus, and any keys I press get interpreted by whatever control had the focus already. This is probably something really simple. The first place I thought to look was in the ControlStyle property, but the only thing I can see in the helpfile about keyboard input is csNoStdEvents, which disables it, and my control doesn't have that. So what do I need to do to make it so my control can receive input focus?

  • Custom layout/group switching keys in Linux

    - by abyx
    I'm using Ubuntu (Karmic) and 2 keyboard layouts. Using the gnome settings, I managed to set it to switch with Alt+Shift (windows style), but I really want to limit it to Right Alt + Right Shift, but that option isn't available in the gnome wizard. I've opened gconf-editor and found the kbd configuration, but trying to add 'r' or 'right_' prefixes to the keys didn't help. Is this possible?

  • Firing a Keyboard Event at the Body - JavaScript (?)

    - by user317985
    I've done a lot of research on this but have come up empty handed. What I would like to do is invoke or create an event for the right arrow key (Key Code 39). I was planning on using an onclick event inside an tag to go to a function where this event could be 'fired'. Any help would be appreciated. If anyone needs context, I have a jQuery content slider that's functionality is very hard to alter and currently the functionality I need to emulate only occurs when a user hits the right arrow on their keyboard. What I would like to do is tie an onclick() event to a image that when clicked on fires the right keyboard event and the content will slide. Please let me know if I can provide further details or explanation. My working demo for this is: http://greenplanet3d.com

  • What can an effective workflow for changing input methods be on Mac OS X?

    - by Martin Josefsson
    I switch between three languages input methods frequently, sometimes in the same typing session. The default shortcut on a Macintosh seems to be to set keyboard shortcuts for previous/next language (I hit opt-cmd-space to go to previous language) and if you're more than bi-lingual you have to cycle until you find the one for you. The ideal would be something like hitting fn-e for English, fn-j for Japanese and fn-g for German, but anything better than the current state would be a great improvement.

  • Pasting a download link into google chrome

    - by fakeit
    When I want to download something in Safari, like http://foo.com/bar.zip, all I have to do is paste that link into the dowloads window. Is there a way to do this in Chrome? I've gotten used to Safari, hitting cmd-alt-L (dowloads window), and then pasting. It's quick, neat, and saves me going to FileSave As... I like to keep my hands on the keyboard, so if there is a quick way to do this without using a mouse, that's my ideal solution.

  • record mouse movements, clicks and keyboard input with Java or C++

    - by Joe
    I want to be able to record mouse movements, clicks and keyboard input from a user. It would be great if it was a cross platform solution. I'd like to get back something like this (pseudo code): mouse moved to 500, 500 mouse double clicked mouse moved to 800, 300 mouse left clicked keyboard typed "Hello World" Does either C++ or Java have any classes that can do this? If I was using C++, I would probably working with the QT framework. Edit: I should have said this originally, but I want to record the movements and clicks outside of the applications gui, so on the desktop too.

  • Firefox: fast dictionary language switching

    - by Lo'oris
    I have two language dictionaries installed on Firefox 3.6, and I would like to be able to switch really fast between them, using the keyboard. At the moment the only way I know I can switch is right clicking in a text input field, go into Language, and then click the language. I would instead to be able to switch between those two just hitting two keys at most, if possible just one (something like F13). Searching for addons I've found tons of extensions somewhat related but that don't actually do what I want.

  • Change section key to less-than in OS X

    - by onik
    I'm having trouble getting my keyboard layout to be properly recognized. At the moment everything else is fine, but my less-than key (<) is mapped to the section key (§), which makes writing HTML a pain. I've tried Ukelele and KeyRemap4MacBook, but can't seem to find the correct settings to change. For reference, this is my layout: Finnish Multilingual, and in System Preferences the input is set to Finnish.

  • shortcut to manually Reload file from Disk

    - by akf
    Now that I can turn off the annoying Reload popups, I would like a quick way to manually reload the file I am working on in NotePad++ via the keyboard. Looking at the File menu, Reload from Disk does not have a shortcut. Is there a hidden shortcut that you know of or someway to map one built-in?

  • UIAlertView popups lock up keyboard actions

    - by TurbZ
    I have a strange behavior where if a UIAlert fires (like the one below) all subsequent keyboard or press behaviors are disabled / non responsive. Scrolling the screen still works but no action is fired from any button or keyboard presses. [[[[UIAlertView alloc] initWithTitle:@"Invalid Address" message:@"The email address you entered isn't valid. Please check and try again." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil] autorelease] show]; Anyone experienced this behavior before and can shed some light? Or maybe guide me in the right direction to debug it further to get to the root cause? Thank you heaps!

  • Z axis trouble with glTranslatef(...) - LWJGL

    - by Zarkopafilis
    Here is the code: private static boolean up = true , down = false , left = false , right = false, reset = false, in = false , out = false; public void start() { try { Display.setDisplayMode(new DisplayMode(800,600)); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); System.exit(0); } GL11.glMatrixMode(GL11.GL_PROJECTION); GL11.glLoadIdentity(); GL11.glOrtho(0, 800, 0, 600, 0.00001f, 1000); GL11.glMatrixMode(GL11.GL_MODELVIEW); Keyboard.enableRepeatEvents(true); while (!Display.isCloseRequested()) { GL11.glClear(GL11.GL_COLOR_BUFFER_BIT); input(); if(up){ GL11.glTranslatef(0,0.1f,0); } if(down){ GL11.glTranslatef(0,-0.1f,0); } if(left){ GL11.glTranslatef(-0.1f,0,0); } if(right){ GL11.glTranslatef(0.1f,0,0); } if(in){ GL11.glTranslatef(0, 0, 1f); } if(out){ GL11.glTranslatef(0, 0, -1f); } if(reset){ GL11.glLoadIdentity(); } GL11.glBegin(GL11.GL_QUADS); GL11.glColor3f(255, 255, 255); GL11.glVertex3f(800/2, 600/2, 0); GL11.glVertex3f(800/2 + 200, 600/2, 0); GL11.glVertex3f(800/2 + 200, 600/2 + 200, 0); GL11.glVertex3f(800/2, 600/2 + 200, 0); GL11.glColor3f(0, 255, 0); GL11.glVertex3f(800/2, 600/2, 1); GL11.glVertex3f(800/2 + 200, 600/2, 1); GL11.glVertex3f(800/2 + 200, 600/2 + 200, 1); GL11.glVertex3f(800/2, 600/2 + 200, 1); GL11.glEnd(); Display.update(); } Display.destroy(); } public static void main(String[] argv){ new main().start(); } public void input(){ up = false; down = false; left = false; right = false; reset = false; in = false; out = false; if(Keyboard.isKeyDown(Keyboard.KEY_SPACE)){ reset = true; } if(Keyboard.isKeyDown(Keyboard.KEY_W)){ up = true; } if(Keyboard.isKeyDown(Keyboard.KEY_S)){ down = true; } if(Keyboard.isKeyDown(Keyboard.KEY_A)){ left = true; } if(Keyboard.isKeyDown(Keyboard.KEY_D)){ right = true; } if(Keyboard.isKeyDown(Keyboard.KEY_Q)){ in = true; } if(Keyboard.isKeyDown(Keyboard.KEY_E)){ out = true; } } As you can see I am creating 2 quads , a white one at z 0 and a green one at z 1. WASD keys function correctly. Also when I hit SPACEBAR the white quad is being shown. If I then press E , I can see the green quad. But if I press Q afterwards , I dont see the white one again!(Space Works everytime). Also if I render the green one at Z = -1 everything works perfectly BUT you may need up to 3 key presses Q/E to see the other quad. Why is that happening?

  • Hooking into comment_text() to add surrounding tag

    - by Stefan Glase
    Trying to hook into the function comment_text() supplied by Wordpress API to wrap the output of every comment into a <div>...</div> container I am running into the following problem: Without my added filter the output of comment_text() looks like this: <p>Hello User!</p> <p>Thank you for your comment.</p> <p>Stefan</p> Thats fine but as I said I would like to have it wrapped into a <div class="comment-text">...</div>. As far as I know the correct way doing this would be in adding a filter to functions.php of my theme and so I did: function stefan_wrap_comment_text($content) { return "<div class=\"comment-text\">". $content ."</div>"; } add_filter('comment_text', 'stefan_wrap_comment_text'); As I can see from the output the given filter works but it has a negative sideeffect to the first paragraph of the content as you can see in the following example. The first paragraph should be <p>Hello User!</p> but looks like this: Hello User!. <div class="comment-text"> Hello User! <p>Thank you for your comment.</p> <p>Stefan</p> </div> Any ideas or hints what I am doing wrong?

  • C# How to find if an event is hooked up

    - by Nick
    I want to be able to find out if an event is hooked up or not. I've looked around, but I've only found solutions that involved modifying the internals of the object that contains the event. I don't want to do this. Here is some test code that I thought would work: // Create a new event handler that takes in the function I want to execute when the event fires EventHandler myEventHandler = new EventHandler(myObject_SomeEvent); // Get "p1" number events that got hooked up to myEventHandler int p1 = myEventHandler.GetInvocationList().Length; // Now actually hook an event up myObject.SomeEvent += m_myEventHandler; // Re check "p2" number of events hooked up to myEventHandler int p2 = myEventHandler.GetInvocationList().Length; Unfort the above is dead wrong. I thought that somehow the "invocationList" in myEventHandler would automatically get updated when I hooked an event to it. But no, this is not the case. The length of this always comes back as one. Is there anyway to determine this from outside the object that contains the event?

  • Finding a 3rd party QWidget with injected code & QWidget::find(hwnd)

    - by David Menard
    Hey, I have a Qt Dll wich I inject into a third-party Application using windows detours library: if(!DetourCreateProcessWithDll( Path, NULL, NULL, NULL, TRUE, CREATE_DEFAULT_ERROR_MODE | CREATE_SUSPENDED, NULL, NULL, &si, &pi, "C:\\Program Files\\Microsoft Research\\Detours Express 2.1\\bin\\detoured.dll", "C:\\Users\\Dave\\Documents\\Visual Studio 2008\\Projects\\XOR\\Debug\\XOR.dll", NULL)) and then I set a system-wide hook to intercept window creation: HHOOK h_hook = ::SetWindowsHookEx(WH_CBT, (HOOKPROC)CBTProc, Status::getInstance()->getXORInstance(), 0); Where XOR is my programs name, and Status::getInstance() is a Singleton where I keep globals. In my CBTProc callback, I want to intercept all windows that are QWidgets: HWND hwnd= FindWindow(L"QWidget", NULL); which works well, since I get a corresponding HWND (I checked with Spy++) Then, I want to get a pointer to the QWidget, so I can use its functions: QWidget* q = QWidget::find(hwnd); but here's the problem, the returned pointer is always 0. Am I not injecting my code into the process properly? Or am I not using QWidget::find() as I should? Thanks, Dave EDIT:If i change the QWidget::find() function to an exported function of my DLL, after setting the hooks (so I can set and catch a breakpoint), QWidgetPrivate::mapper is NULL.

  • How to redirect registry access of a dll loaded by my program

    - by dummzeuch
    I have got a dll that I load in my program which reads and writes its settings to the registry (hkcu). My program changes these settings prior to loading the dll so it uses the settings my program wants it to use which works fine. Unfortunately I need to run several instances of my program with different settings for the dll. Now the approach I have used so far no longer works reliably because it is possible for one instance of the program to overwrite the settings that another instance just wrote before the dll has a chance to read them. I haven't got the source of the dll in question and I cannot ask the programmer who wrote it to change it. One idea I had, was to hook registry access functions and redirect them to a different branch of the registry which is specific to the instance of my program (e.g. use the process id as part of the path). I think this should work but maybe you have got a different / more elegant. In case it matters: I am using Delphi 2007 for my program, the dll is probably written in C or C++.

  • Any simple shape recognition libraries for Java?

    - by Phil
    I am working on a on-screen keyboard for Android, and I need to recognize starting points, turning points and end points of lines drawn by the user on the keyboard. A simple straightening function would be nice, as it is difficult to draw a perfectly straight line even with a stylus, not to mention finger-only touchscreens today. What I am trying to write is something like Swype. Any good libraries that I can use or make reference to?

  • ubuntu gnome short cut keys

    - by benjipete
    Hi, I have done something quite silly and not sure how to fix it. I modified some of the gnome keyboard short cuts and was trying to disable the "Run Application" command. In the process I assigned it to the delete key and every time I hit delete the "Run Application" window comes up. It would not normally be a problem but the "Keyboard Shortcuts" no long has the short cut in the window so I can't disable it. Any help advice would be appreciated. Cheers Ben
