The following change to osgViewer allows OSG applications built
on OSX outside of Xcode (i.e. not as a .app bundle) to obtain
keyboard focus. Before Robert commits the change it would for
worthwhile for Xcode users to verify that this doesn't interact
badly with apps that have already become foreground applications
(e.g. those started from a .app bundle, which presumably does
this at initialization time).
the calls to add at the end of GraphicsWindowCarbon::realizeImplementation
(in src/osgViewer/GraphicsWindowCarbon.cpp):
ProcessSerialNumber sn = { 0, kCurrentProcess };
TransformProcessType(&sn,kProcessTransformToForegroundApplication);
SetFrontProcess(&sn);
it must be said that I'm not a Carbon hacker, so someone with better knowledge
of Carbon programming may see a more appropriate place for this.
(also: TransformProcessType was apparently introduced in OSX 10.3, don't know
how to do this for earlier versions)
