Hi OM,
What I have done is merged a couple of your changes to GUIEventAdapter
and GUIEventHandler and then added a few extra changes, these are:
The addition of two inline
GUIEventHandler::handleWithCheckAgainstIgnoreHandledEventsMask(..)
methods which are now called by Viewer.cpp and CompsiteViewer.cpp.
This should allow all event handles including callbacks to function
the same w.r.t the new mask. The body of the new methods looks like
this:
inline bool
handleWithCheckAgainstIgnoreHandledEventsMask(const GUIEventAdapter&
ea,GUIActionAdapter& aa, osg::Object* object, osg::NodeVisitor* nv)
{
if (!ea.getHandled() ||
(ea.getEventType() & _ignoreHandledEventsMask)==0)
{
bool handled = handle(ea,aa,object,nv);
if (handled) ea.setHandled(true);
return handled;
}
else
{
return false;
}
}
I have also change the setIgnoreUsedEventsMask to
setIgnoreHandledEventsMask to keep it consistent with the rest of the
event methods i.e. handle/setHandled().
Could you let me know how you get on with these changes.
Robert.
