Re: [osg-users] Can we add Viewer::setSkipCloseWindowEvent to prevent Window from being closed upon receiving CLOSE_WINDOW?

2012-10-25 Thread Robert Osfield 
HI Micahel,

Are you talking about the following code in Viewer::eventTraversal()
that responds to the osgGA::GUIEventAdapter::CLOSE_WINDOW event?

for(itr = gw_events.begin();
itr != gw_events.end();
++itr)
{
osgGA::GUIEventAdapter* event = itr-get();
switch(event-getEventType())
{
case(osgGA::GUIEventAdapter::CLOSE_WINDOW):
{
bool wasThreading = areThreadsRunning();
if (wasThreading) stopThreading();

gw-close();
_currentContext = NULL;

if (wasThreading) startThreading();

break;
}
default:
break;
}
}

It would be possible to make this optional, in the same way the
EscapeSetsDone flag is used.  Without any modifications to the OSG the
way to avoid the issue would be to subclass from Viewer and override
the eventTraversal() method.

Robert.

 I've looked at the code (OSG 3.0.1) of Viewer::eventTraversal and
 noticed that it checks for CLOSE_WINDOW event and closes the window,
 so there's no way to prevent the window from closing. I've googled for
 window close prevention with no luck, too.
 Can we add something like Viewer::setSkipCloseWindowEvent to OSG?
 Thanks.

Hi Mcahel,

The question is how one might go about the patch.  One could modify
ViewerBase to add g/setIgnoneCloseEvent(bool)  and then read this in
Viewer/CompositeViewer::eventTraversals() method, or go about it at
the GraphicsWindow level by creating a window that doesn't have a
close button.  Is there a reason why you aren't doing the later?

Robert.

Well, something like Alt-F4 is very-very intuitive, so forbidding it
will increase the number of angry people :)
