From f13f0db33a18040e660b6ed76ad43d1870f096a2 Mon Sep 17 00:00:00 2001 From: Stefano Pigozzi Date: Sun, 2 Jun 2013 17:39:05 +0200 Subject: osx: create macosx_events to deal with keyDown events On OSX with Cocoa enabled keyDown events are now handled with addLocalMonitorForEventsMatchingMask:handler:. This allows to respond to events even when there is no VO initialized but the GUI is focused. --- osdep/macosx_events.m | 141 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 141 insertions(+) create mode 100644 osdep/macosx_events.m (limited to 'osdep/macosx_events.m') diff --git a/osdep/macosx_events.m b/osdep/macosx_events.m new file mode 100644 index 0000000000..434fc0cb3b --- /dev/null +++ b/osdep/macosx_events.m @@ -0,0 +1,141 @@ +/* + * Cocoa Application Event Handling + * + * This file is part of mpv. + * + * mplayer2 is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * mplayer2 is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
