MythTV-Setup stops listening to some keyboard input

[Brian Boonstra <mythtv@…>]

MythTV-Setup.app will behave normally with keyboard input for about a minute. Then it will stop listening to the Enter key, arrow keys and Escape key at the top level menus. This can be worked around, mostly, by task-switching to find the mouse cursor and clicking buttons using the mouse. However the app must be killed by hand to quit it.

Logging with -v shows the following output:

AppleRemote::startListening() failed

This is on a machine that lacks an Apple Remote. It is running OSX 10.7 Lion, using the backend binaries downloaded from SourceForge? on April 10 2012.

Note that this issue only occurs when you use Qt 4.7 and later, and compile using llvm/clang

It doesn't occur when compiling with gcc (Xcode 3.x)

Also, unlike the initial report, it has nothing to do with timing. It only occurs when you go into the settings menu. If you only ever go into playback, recording screens etc... the problem will not occur

Fix non-responsive keyboard on mac

QWidget::winId() forces a widget to be native. Why it causes some keyboard issues on mac I'm not sure. It's likely we don't need this call at all, including non-mac. Take the safe approach and only disable the call on mac

Fixes #10587
