Revision 12125, 6.7 kB (checked in by robert, 3 years ago)

From Alexander Sinditskiy, "reason of this changes described in http://forum.openscenegraph.org/viewtopic.php?t=7596

and another problem is:
example osgkeyboard is not work (keys not highlight) if user have 2 keyboard layout native and english and current user layout is native

I try to explain my changes

we need something that is identify key without modifier keys and layout -> this is UnmodifedKey?

I think osg must have its own UnmodifiedKeys? table. Code must be run same on different platforms. This can de guaranteed by UnmodifiedKeys? table.

Mikhail Izmestev helped me. He implemented VirtualKey? changes in GraphicsWindowX11"

  • Property svn:eol-style set to native
