What is the Function key called in AutoHotkey?

阅读更多关于 What is the Function key called in AutoHotkey?

问题 I have a key labelled Fn in blue letters at the bottom of my Windows 7 keyboard. I want to trigger my AutoHotkey script whenever someone presses that key. What is the Function key called in AutoHotkey? 回答1: The problem with the Fn key is, that a lot of keyboards don't implement it as normal key, but as a modifier that changes the key messages of other keys pressed at the same time. So here is an example scenario of how Windows could see your input: Press F1 down - Windows receives the F1 down

JavaFX weird (Key)EventBehavior

阅读更多关于 JavaFX weird (Key)EventBehavior

So I have been experimenting with it a litle bit with javaFX and I came across some rather weird behavior which might be linked to the TableView#edit() method. I'll post a working example on the bottom of this post again, so you can see what exactually is happening on which cell (debuging included!). I'll try to explain all the behavior myself, though its way easier to see it for yourself. Basically the events are messed up when using the TableView#edit() method. 1: If you are using the contextMenu to add a new item, the keyEvents for the the keys 'escape' and 'Enter' (and propably the arrow

onKeyUp not firing for ESC in IE

阅读更多关于 onKeyUp not firing for ESC in IE

I have a page where I have to close a dialog when Esc is pressed. I wrote the following simplified code example for this task: <html> <head> <script language="JavaScript"> function keyUpExample() { alert('on' + event.type + ' event fired by ' + '"' + event.srcElement.id + '" ' + ' ' + event.which) } </script> </head> <body id="myBody" onkeyup="keyUpExample()"> Trying keyUp event: Press any key... </body> </html> This works as expected under Chrome but is NOT working under IE 7. Is there any workaround on order to cope this problem? Thanks in advance! Key events don't have to be caught by the

问题 I need to be able to replace a keystroke with jQuery. When the right arrow is pressed, I want the tab key to be pressed instead. So far I have: <script type="text/javascript" src="jquery-1.6.1.min.js"></script> <script type="text/javascript" src="jquery.simulate.js"></script> <script type="text/javascript"> $(function () { $("select").each( function() { $(this).keydown(function(event) { if (event.which == '39') { $(this).simulate("keydown", { keyCode: 9, ctrlKey: false, shirtKey: false }); $

pygame capture keyboard events when window not in focus

阅读更多关于 pygame capture keyboard events when window not in focus

问题 I wrote a simple python script that gives control over the cursor to a joystick. My way to find out how this works is documented here. Now that works flawlessly but, as soon as I start the script to use the joystick, the mouse is useless, because my python routine sets the value back to its original, whenever a new joystick event comes in. Thus I want my joystick events to be ignored as long as a key of the keyboard is pressed. I came across the pygame.key.get_pressed() method but this seems

Remapping the Keyboard at a low level

阅读更多关于 Remapping the Keyboard at a low level

We are replacing a legacy C application originally written for MSDOS (yes, believe it or not!). This application uses a specially remapped keyboard which intercepts the DOS keyboard interrupt (remember that??!) to sometimes alter the scan codes of the keys pressed by the user so that different processing would occur. Special labels were then placed on the keys telling the users the "new" meaning of these keys. The new Java version is required to preserve this keyboard layout which the targeted group of users is very familiar with. An example of what we are trying to do is as follows: You may

Correctly getting key being pressed for chat in XNA

阅读更多关于 Correctly getting key being pressed for chat in XNA

So, I'm going to cut straight to it, I'm trying to make a chat system in an XNA game I'm making. I can easily figure out what keys are being pressed BUT I have no way of knowing what is actually being typed. To me, it looks like they are saying: OemShifthello billOemPeriod OemShifthow are youOemQuestion which should look like Hello bill. How are you? (or something along those lines). Whats the best way to handle all of this? For the PC there's nothing built in to the XNA framework making that easy (it's a different story for WP7 and the Xbox). This post here summarizes pretty much all of your

SDL 2.0 Key repeat and delay

阅读更多关于 SDL 2.0 Key repeat and delay

I'm having a problem with SDL 2.0 keyboard input in pong-like game. When I order to move to the left by pressing left arrow, it is processed by SDL_PollEvents() and responds correctly if the key was pressed once. However, if I keep the key pressed, I get a short delay (as long as Windows key repeat delay) before moving continuously. Here is function processing events: void Event::PlayerEvent (Player &player) { while (SDL_PollEvent (&mainEvent)) { switch (mainEvent.type) { case SDL_KEYDOWN : switch (mainEvent.key.keysym.sym) { case SDLK_ESCAPE : gameRunning = false; break; case SDLK_LEFT :
