keyboard-events

问题 I have a simple snippet(not MVC) of code looking like the following # include <Cocoa/cocoa.h> int main(argc, *argv[]) { [NSApplication sharedApplication] [NSEvent addGlobalMonitorForEventsMatchingMask:NSKeyUpMask handler:^(NSEvent *evt){ .... }] [NSApp run] } When compiled as command line binary and run, the global event monitoring works, after allowing the program from system preferences -> privacy & security; then I packed it int an .app, and ran it, the global monitor stopped working even

问题 I want to fire off an event before my focus on a textarea (i.e. before the keyboard appears on iOS). Is this possible? My code to handle the focus is here: $(document).on('focus', 'textarea', function() { console.log("focus event"); }); 回答1: Try touchstart Event $(document).on('touchstart', 'textarea', function() { console.log("touchstart event"); }); 回答2: I would use the focusin event note that this event catch the child elements focus as well. focusin: sent before first target element

问题 I am trying to type all the possible keys from Keyboard, irrespective of languages or layout using Java Robot. We have written a super class which has common methods to print characters KeyEvent.VK_A to KeyEvent.VK_Z , number KeyEvent.VK_0 to KeyEvent.VK_9 along with SHIFT key combination. Now coming to specific part that is if we are having Italy or Turkish Keyboard which are having Unicode present or if any other special character. How can I stimulate the same keypress or keyrelease ? (as

问题 I'm curious if it's possible to detect when the "fn" key is pressed on a mac keyboard, either when it's used on its own or when used in combination with another key. Is there a way to do that? I'm open to using any sort of method, including undocumented Apple APIs if necessary. 回答1: All keyboard NSEvents will have NSEventModifierFlagFunction (NSEvent.ModifierFlags.function in Swift) in their .modifierFlags when the Fn key is down. To test for Fn on its own rather than in combination with some

问题 I have an app made in .NET 4.0 that hooks on win events and uses a callback to catch the window events like so: //import the methos from the dll [DllImport("user32.dll", SetLastError = true)] private static extern IntPtr SetWinEventHook(int eventMin, int eventMax, IntPtr hmodWinEventProc, WinEventProc lpfnWinEventProc, int idProcess, int idThread, int dwflags); //declare a callback public static WinEventProc _winEventProc = new WinEventProc(WindowEventCallback); //pass this callback to

问题 In my application I have a JTable where I mapped a Key event. The source: getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "selectNextColumnCell"); getActionMap().put("selectNextColumnCell", new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { //DO SOMETHING } }); } But this action is only called when I press the enter key and don't release it. But I need call this action every time when the user type the

问题 You may have read my earlier question about remapping my keyboard at a low level in Java and I did find a solution - mostly. To be honest, I oversimplified the problem I was trying to solve. I not only want to match NumericKeypad 1-3 to 7-9 and vice versa, I want to remap the whole numeric keypad. In particular, I need to remap the NumLock key which is part of that keypad. This seems to be intercepted on a System level and I cannot just map it to emit some character. What I want is that when

问题 OnKeyDown callback in InputMethodService works for a lot of hardware keyboard buttons but It doesn't fire with Left, Right, Up, Down arrow. How can I handle it? Thanks for your attention! 回答1: Have you looked at the developer documentation on handling key events? You could try onKeyDown or onKeyUp to only receive one event and print out the keyCode to see what is getting received: @Override public boolean onKeyUp(int keyCode, KeyEvent event) { Log.i("your tag", "Keycode: " + keyCode); switch

问题 I have this Autohotkeys script and I need help on it. By pressing win+b the window will move the the other monitor, in this case monitor 2.

问题 is there a quick way to use the right and left arrow keys to load the next page? My solution so far is: $(document).ready(function () { $("a.transition").click(function (event) { event.preventDefault(); linkLocation = this.href; $("body").fadeOut(20, redirectPage); }); $("a.transitionB").click(function (event) { event.preventDefault(); linkLocation = this.href; $("body").fadeOut(20, redirectPage); }); function redirectPage() { window.location = linkLocation; } }); with 2 invisible link layers
