Re: [osg-users] ViewerEventHandlers problem with custom GUIEventHandlers
Well I modified the osgkeyboard example, and added a StatHandler so that main
now is:
int main(int , char **)
{
osgViewer::Viewer viewer;
osg::ref_ptrKeyboardModel keyboardModel = new KeyboardModel;
viewer.addEventHandler(new KeyboardEventHandler(keyboardModel.get()));
viewer.addEventHandler(new osgViewer::StatsHandler);
viewer.setSceneData( keyboardModel-getScene() );
return viewer.run();
}
But still pressing s, presses the s key in the virtual keyboard and also shows
stats.
I didn't have this problem with osgProducer::Viewer but appeared when I ported
to osgViewer::Viewer.

I think you have a point there. But even if I inverse my handler, things
again do not work. I also tried setting setHandled to true but again
nothing!
I looked at the code and StatsHandler works on KEYDOWN; so, just make
sure your event handler is front of the StatsHandler when you add it to
the viewer (either by hand or by calling push_front()) and return true
on that event and you should be okay. Alternatively, you can call:
statsHandler-setKeyEventTogglesOnScreenStats()
...to change it from S to something else.

I would guess that one does key press (perhaps yours), and the other
release (perhaps StatsHandler). I haven't checked the source to
confirm, but I bet this is what is happening...

Re: [osg-users] ViewerEventHandlers problem with custom GUIEventHandlers
Thank you Robert! Now everything is Ok!
On Tuesday 03 July 2007 16:18, Robert Osfield wrote:
Hi Panagiotis,
The behavior difference you are seeing is down to the osgViewer using
the Chain of Responsibility Design Pattern for passing on events, the
just of it is that viewer passes events to all event handlers
regardless of whether the event has been handled or not. The approach
pushes the responsibility for checking to see if the event has been
handled on to the event handlers themselves. They can check this via
the GUIEventAdapter::getHandled() method. If an event handler returns
true then the Handled bool is automatically set to true.
The problem that you have observed arises when an event handler has
been updated to filter out already handled events, some of the osgGA
event handles like the camera manipulators had been updated, but not
all - the osgGA::StatsManipulator and osgViewer::ViewerEventHandlers
hadn't been updated for 2.0. I have just gone through these event
handlers and added in the appropriate code - mostly checks like:
if (ea.getHandled()) return false;
Added to the *::handle(..) methods.
With this change your code example:
int main(int , char **)
{
osgViewer::Viewer viewer;
osg::ref_ptrKeyboardModel keyboardModel = new KeyboardModel;
viewer.addEventHandler(new KeyboardEventHandler(keyboardModel.get()));
viewer.addEventHandler(new osgViewer::StatsHandler);
viewer.setSceneData( keyboardModel-getScene() );
return viewer.run();
}
Will result in the StasHandler getting events but discarding them as
they have already been handled by the KeyboardEventHandler. If
however, you change the order, then the stats will work and the
keyboard handler will work as the later doesn't check for
getHandled(). In this instance this is what you want, and the new
Chain of Responsibility approach is working as intended giving you the
flexibility to control how events are handled.
Robert.
