keyboard-events

Has anyone had any luck simulating Caps Lock keystroke with CGEventCreateKeyboardEvent on OS X? Basically I have tried alphabetic character and alphanumeric character okay but Caps Lock. Hopefully, I would like to simulate Caps Lock keystroke to trun on/off the LED. I don't know what problem is for my test code. Has anyone had experinces for this? #include <stdio.h> #include <ApplicationServices/ApplicationServices.h> main() { bool wasCapsLockDown = CGEventSourceKeyState(kCGEventSourceStateHIDSystemState, 57); if (wasCapsLockDown) printf("On\n"); else printf("Off\n"); ProcessSerialNumber psn;

I have an app with a login page that has three fields for three different random characters. When the user leaves the last field, the soft keyboard disappears and the user can touch a "login" button on screen. When there is a hardware keyboard (bluetooth or physical) attached, I'd like to be able to hit "enter" on it. However because the user is not in a field, I can't see how to detect this key being pressed. Would anyone have advice on which class handles key press events? Presumably there is a delegate that I can use to receive these but my searches through the SDK haven't found anything.

I am using the direct following and I do not detect the copy and paste with the keys inside the input, would someone know how? Thank you! export class OnlyNumberDirective { // Allow decimal numbers. The \, is only allowed once to occur private regex: RegExp = new RegExp(/[0-9]+(\,[0-9]{0,1}){0,1}$/g); // Allow key codes for special events. Reflect : // Backspace, tab, end, home private specialKeys: Array<string> = [ 'Backspace', 'Tab', 'End', 'Home', 'Delete', 'Del', 'Ctrl', 'ArrowLeft', 'ArrowRight', 'Left', 'Right' ]; constructor(private el: ElementRef) { } @HostListener('keydown', [ '$event

I need to fire the Ctrl + R , Ctrl + A , Ctrl + Q events when a user clicks on a button. I was working on the following code: $(document).ready(function () { $('#Button1').click(function () { var evt = $.Event("keypress"); evt.keyCode = 81; evt.ctrlKey = true; evt.shiftKey = true; $(document).trigger(evt); }); }); PurkkaKoodari You can't simulate browser control keys, but you can simulate their effects. Ctrl - R refreshes. function refresh() { location.reload(true); } Ctrl - A selects everything. Code is from here . function selectAll() { var e = document.getElementsByTagName('body')[0]; var r

The problem I'm having is that I'm trying to make my character move diagonally on screen when a user presses either the K_UP key and K_RIGHT key or the K_UP key and K_DOWN key, etc. Here is my code for character movement (event handling): 1. #Event Handling 2. for event in pygame.event.get(): 3. if event.type == pygame.QUIT: 4. sys.exit() 5. elif (event.type == KEYDOWN): 6. if ((event.key == K_ESCAPE) 7. or (event.key == K_q)): 8. sys.exit() 9. if (event.key == K_UP): 10. self.char_y = self.char_y - 10 11. if (event.key == K_DOWN): 12. self.char_y = self.char_y + 10 13. if (event.key == K

I would like to hook into, intercept, and generate keyboard (make/break) events under Linux before they get delivered to any application. More precisely, I want to detect patterns in the key event stream and be able to discard/insert events into the stream depending on the detected patterns. I've seen some related questions on SO, but: either they only deal with how to get at the key events (key loggers etc.), and not how to manipulate the propagation of them (they only listen, but don't intercept/generate). or they use passive/active grabs in X (read more on that below).
