If it is, then use a NSFlagsChanged event type. This will generate a NSFlagsChanged event each time you press/release a shift key, even if the flags haven't actually changed. I don't see this as a problem - if we didn't, the shift keypress/keyrelease event would never be notified to the application. NB - to know if shift was pressed, we need to check the X keysym - it doesn't work to compare the X modifier flags of this keypress X event with the ones of the previous one, because when you press Shift, the X shift keypress event has the *same* X modifiers flags as the X keypress event before it - only keypresses coming *after* the shift keypress will get a different X modifier mask. */ if (keysym_is_X_modifier (keysym)) { eventType = NSFlagsChanged; } if (help_key) { unicode = NSHelpFunctionKey; keys = [NSString stringWithCharacters: &unicode length: 1]; if (originalType == NSKeyDown) { event = [NSEvent keyEventWithType: NSKeyDown location: eventLocation modifierFlags: eventFlags timestamp: (NSTimeInterval)xEvent->xkey.time windowNumber: window->number context: GSCurrentContext() characters: keys charactersIgnoringModifiers: keys isARepeat: NO keyCode: keyCode]; [event_queue addObject: event]; event = [NSEvent keyEventWithType: NSFlagsChanged location: eventLocation modifierFlags: eventFlags timestamp: (NSTimeInterval)xEvent->xkey.time windowNumber: window->number context: GSCurrentContext() characters: keys charactersIgnoringModifiers: keys isARepeat: NO keyCode: keyCode]; return event; } else { event = [NSEvent keyEventWithType: NSFlagsChanged location: eventLocation modifierFlags: eventFlags timestamp: (NSTimeInterval)xEvent->xkey.time windowNumber: window->number context: GSCurrentContext() characters: keys charactersIgnoringModifiers: keys isARepeat: NO keyCode: keyCode]; [event_queue addObject: event]; event = [NSEvent keyEventWithType: NSKeyUp location: eventLocation modifierFlags: eventFlags timestamp: (NSTimeInterval)xEvent->xkey.time windowNumber: window->number context: GSCurrentContext() characters: keys charactersIgnoringModifiers: keys isARepeat: NO keyCode: keyCode]; return event; } } else { /* Now we get the unicode character for the pressed key using our * internal table. */ unicode = process_char (keysym, &eventFlags); /* If that didn't work, we use what X gave us */ if (unicode != 0) { keys = [NSString stringWithCharacters: &unicode length: 1]; } // Now the same ignoring modifiers, except Shift, ShiftLock, NumLock. xEvent->xkey.state = (xEvent->xkey.state & (ShiftMask | LockMask | _num_lock_mask)); ukeys = [context->inputServer lookupStringForEvent: (XKeyEvent *)xEvent window: window keysym: &keysym]; unicode = process_char (keysym, &eventFlags); if (unicode != 0) { ukeys = [NSString stringWithCharacters: &unicode length: 1]; } event = [NSEvent keyEventWithType: eventType location: eventLocation modifierFlags: eventFlags timestamp: (NSTimeInterval)xEvent->xkey.time windowNumber: window->number context: GSCurrentContext() characters: keys charactersIgnoringModifiers: ukeys isARepeat: NO /* isARepeat can't be supported with X */ keyCode: keyCode]; return event; } } static unichar process_char (KeySym keysym, unsigned *eventModifierFlags) { switch (keysym) { /* NB: Whatever is explicitly put in this conversion table takes precedence over what is returned by XLookupString.
