[osg-users] Keyboard handler: SHIFT modifier doesn't work on Linux

[Michael Rubin]

Hello,

The SHIFT modifier does not appear to be working correctly on my Linux app (OSG 3.0.1) -- it is always on (so all typing in my debug console appears as upper-case).

I've seen posts like this (http://comments.gmane.org/gmane.games.flightgear.devel/65510) which claim that X is sending the incorrect events to the window, but using `xev` I've confirmed that my window (i.e. OSG) is receiving the correct events for shift down, shift up, etc. However, as a client of OSG, I'm not receiving correct modifiers (in the mask param of my callback function).

On Windows (also OSG 3.0.1), everything works as expected.

Does anyone have any suggestions that I could apply?

Thank you very much,
Mike

Hi Michael,

Could you try the osgkeyboard example, I've just tried this on my Kubuntu 12.04 system and it's still working fine - the shift key on it's own, and A/a work just fine.

What type of windowing system are you using on your desktop and for the OSG?

Robert.

Example works fine -- thanks for the tip! I've tracked the issue (in my code) to masking against osgGA::GUIEventAdapter::KEY_Shift_L instead of (like the example) osgGA::GUIEventAdapter::MODKEY_LEFT_SHIFT.

Thank you very much for the quick response,

Mike
