[osg-users] patch to add WMclass to osgViewer

[S Andreason]

Hi,

When I open the Window Attributes (in WindowManager in X on linux) I am
unable to save any changes to the attributes in the resource database,
because the osg window does not have a class defined. The Window
Specification and Save buttons are greyed out.

For example, when running FlightGear, I want the window to always have
no title, so it opens full-screen without using the --full-screen
option, which would prevent other windows from moving above the osg window.

I am attaching a patch I made to fix this problem.

Thank you,
Stewart

Thanks Stewart, change now merged and submitted to svn/trunk. For
future submissions could you send the whole modified file as I find
this far more reliable than using patch, as patch can mess up.
Cheers, Robert.
