Re: [Flightgear-devel] Keyboard weirdness: shift modifier stays on

[Sylvain M. <syl...@gm...>]

OK,

I tracked this, I am answering myself for the record.

On my system, I had to recompile OSG.
It seems on left-shift-key release, Xorg sends a release event with a wrong
keysym (XK_ISO_Prev_Group instead of XK_Shift_L).

Same thing for right shift key. On release, the X11 keysym is
XK_ISO_Next_Group instead of XK_Shift_R.

So i  remap these in OSG through the _extendedKeymap of GraphicsWindowX11.
I add the following remappings in GraphicsWindowX11.cpp of osgViewer:

            _extendedKeymap[XK_ISO_Prev_Group] =
osgGA::GUIEventAdapter::KEY_Shift_L;
            _extendedKeymap[XK_ISO_Next_Group] =
osgGA::GUIEventAdapter::KEY_Shift_R;

Not sure this is the correct solution, though. It works for me.

Maybe this concerns OSG people? Xorg people?

Cheers,
Sylvain.
