Hi all,
I'm having this weird issue after upgrading iWork on Mountain Lion.
I wrote a small app to monitor and modify user's keystrokes, it works
fine with other applications except latest version of Pages. Every time
I send keyboard events with unicode strings contain 2-byte unicode
characters, Pages will hang.
My code to simulate keystrokes is just simple like this:
CGEventRef KeyHandler(CGEventTapProxy proxy, CGEventType type,
CGEventRef event, void *refcon)
{
......
CGEventRef keyEventDown = CGEventCreateKeyboardEvent( NULL, 1, true);
CGEventRef keyEventUp = CGEventCreateKeyboardEvent(NULL, 1, false);
CGEventKeyboardSetUnicodeString(keyEventDown, 1, unicodeString);
CGEventKeyboardSetUnicodeString(keyEventUp, 1, unicodeString);
CGEventTapPostEvent(proxy, keyEventDown);
CGEventTapPostEvent(proxy, keyEventUp);
CFRelease(keyEventDown);
CFRelease(keyEventUp);
......
}
Pages doesn't hang if unicodeString contains only 1-byte unicode character.
I used gdb to debug Pages and noticed 2 infinite loops at that time, not
sure if it's related to this issue.
0x91f7528c in -[NSApplication
nextEventMatchingMask:untilDate:inMode:dequeue:] () which waited for
event with mask 0xffffffff
0x91f7528c in -[NSApplication
nextEventMatchingMask:untilDate:inMode:dequeue:] () which waited for
event with mask 0x00000400
Does anybody know why this is happening ? Numbers and Keynote also have
the same issue.
Thanks,
