I do this in osgWidget by making my WindowManager derive from
osg::Switch, which provides setAllChildren{On/Off}. Plus, each
osgWidget::Window object provides show()/hide() methods, which just
communicate with parent WindowManager and ask it to hide/show
themselves.What you should do though it just see if osgWidget can do some of what you want, bug me to fix what it doesn't, and in the end help it get better for submission to OSG. *grin* I only mention this because you said "any good solution appreciated." :) On Wed, 2008-03-12 at 23:46 +0530, Night Hawk wrote: > Hello all, > > I am displaying the nodes under mouse on a HUD (based on the Pick Example). > > I am trying to turn this display on/off based on if user presses some > key.
