Consider reading this page about handling exceptions.. It should help. As @abarnert has said, do sys.exit() after except KeyboardInterrupt:. Something like try: # DO THINGS except KeyboardInterrupt: # quit sys.exit() You can also use the built in exit() function, but as @eryksun pointed out, sys.exit is more reliable.
You can send key events, and anything listening for them will get them, but they will not change the input, so you will not see the letter A appear, for example. This is mostly a security thing; see “Manually firing events” for a discussion about that. So, if you want the letter to appear, you … Read more
This I think will do the job, or if not is very close and will need only minor tweaking. The thing you have to remember is that you can’t reliably tell anything at all about any character that may be typed in a keydown or keyup event: that all has to be done in a … Read more
I am working on DOM Keyboard Event Level 3 polyfill . In latest browsers or with this polyfill you can do something like this: element.addEventListener(“keydown”, function(e){ console.log(e.key, e.char, e.keyCode) }) var e = new KeyboardEvent(“keydown”, {bubbles : true, cancelable : true, key : “Q”, char : “Q”, shiftKey : true}); element.dispatchEvent(e); //If you need legacy … Read more
I agree with William that in general it is a bad idea to hijack the function keys. That said, I found the shortcut library that adds this functionality, as well as other keyboard shortcuts and combination, in a very slick way. Single keystroke: shortcut.add(“F1”, function() { alert(“F1 pressed”); }); Combination of keystrokes: shortcut.add(“Ctrl+Shift+A”, function() { … Read more
The question is tagged WPF but the answers so far are specific WinForms and Win32. To do this in WPF, simply construct a KeyEventArgs and call RaiseEvent on the target. For example, to send an Insert key KeyDown event to the currently focused element: var key = Key.Insert; // Key to send var target = … Read more
It can be done using ctypes: import ctypes from ctypes import wintypes import time user32 = ctypes.WinDLL(‘user32’, use_last_error=True) INPUT_MOUSE = 0 INPUT_KEYBOARD = 1 INPUT_HARDWARE = 2 KEYEVENTF_EXTENDEDKEY = 0x0001 KEYEVENTF_KEYUP = 0x0002 KEYEVENTF_UNICODE = 0x0004 KEYEVENTF_SCANCODE = 0x0008 MAPVK_VK_TO_VSC = 0 # msdn.microsoft.com/en-us/library/dd375731 VK_TAB = 0x09 VK_MENU = 0x12 # C struct definitions wintypes.ULONG_PTR … Read more
You can use this one also (sets a special listener to be called when an action is performed on the EditText), it works both for DONE and RETURN: max.setOnEditorActionListener(new OnEditorActionListener() { @Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_DONE)) { Log.i(TAG,”Enter … Read more
Arrow keys are only triggered by onkeydown, not onkeypress. The keycodes are: left = 37 up = 38 right = 39 down = 40
The whole point of jQuery is that you don’t have to worry about browser differences. I am pretty sure you can safely go with enter being 13 in all browsers. So with that in mind, you can do this: $(document).on(‘keypress’,function(e) { if(e.which == 13) { alert(‘You pressed enter!’); } });
