Pygame keyboard layouts mixed up

阅读更多关于 Pygame keyboard layouts mixed up

问题 I'm on Mac OS X 10.6, and I have Dvorak, US Extended, and Norwegian in my keyboard input selector menu, and US Extended is the one I use. When I run Pygame programs with keyboard input, pygame seems to think I'm using dvorak regardless of what is actually selected. This is the part of the code that takes the keyboard input: # Check for events for event in pygame.event.get(): if event.type == KEYDOWN: # Change the keyboard variables if event.key == K_LEFT or event.key == ord('a'): moveRight =

Python bind - allow multiple keys to be pressed simultaniously

阅读更多关于 Python bind - allow multiple keys to be pressed simultaniously

问题 I have a problem in Python. I'm using Tkinter and have four bind events, that listen to key presses on my form. My problem is, that these don't run asynchronously. So, for example I can press one button, and the events are recognized. But when I press and hold two keys at the same time, just one event gets fired. Is there an alternative way to do this? self.f.bind("w", self.player1Up) self.f.bind("s", self.player1Down) self.f.bind("o", self.player2Up) self.f.bind("l", self.player2Down) 回答1:

Is there a cross-platform python low-level API to capture or generate keyboard events?

阅读更多关于 Is there a cross-platform python low-level API to capture or generate keyboard events?

问题 I am trying to write a cross-platform python program that would run in the background, monitor all keyboard events and when it sees some specific shortcuts, it generates one or more keyboard events of its own. For example, this could be handy to have Ctrl-@ mapped to "my.email@address", so that every time some program asks me for my email address I just need to type Ctrl-@. I know such programs already exist, and I am reinventing the wheel... but my goal is just to learn more about low-level

How to grab keyboard events on an element which doesn't accept focus?

阅读更多关于 How to grab keyboard events on an element which doesn't accept focus?

I know that for handling keyboard events in an input field you can use: $('input').keyup(function(e){ var code = e.keyCode // and 13 is the keyCode for Enter }); But, now, I have some div and li elements, and I don't have a form element, and none of my elements are considered to be form elements and none of them accept focus or tab and stuff like that. But now I need to handle the keyup (or keydown , or keypress , doesn't matter) event in a div element. I tried: $('div#modal').keyup(function(e){ if (e.keyCode == 13) { $('#next').click(); // Mimicking mouse click to go to the next level. } });

问题 I'd like to trigger an event in AutoHotkey when the user double "presses" the esc key. But let the escape keystroke go through to the app in focus if it's not a double press (say within the space of a second). How would I go about doing this? I've come up with this so far, but I can't work out how to check for the second escape key press: ~Esc:: Input, TextEntry1, L1 T1 endKey=%ErrorLevel% if( endKey != "Timeout" ) { ; perform my double press operation WinMinimize, A } return 回答1: Found the

Something like try: # DO THINGS except KeyboardInterrupt: # quit sys.exit() You can also use the built in exit() function, but
