Hi Adrian,

may i do something wrong, or the osgViewer for Carbon is not right, i don't
know. The result should looking like "Bild 3". the "Bild 1" and "Bild 2" are

window not moved, Bild 2 after bild moved)
I am not sure if your usage-scenario is currently doable with
GraphicsWindowCarbon. You want to attach a HIView (or what it is called
in Carbon) , which is part of a window to the osgViewer::Viewer.
GraphicWindowCarbon owns whole windows, it takes all the place, it eats
all the events, so other ui-items get lost. It is not designed to handle
only a view.
The current implementation of GraphicsWindowCarbon does not process any
events, if it gets a "foreign" window. If you want to install the
eventhandlers, with a foreign window, set
m_windowData->setInstallEventHandler(true);
This may not work for your settings, because GraphicsWindowCarbon
installs several event handlers to catch Application-Quit etc.
Perhaps it is the best way to implement your own native
GraphicsContext-implementation for the plugin-usage or use a
GraphicsWindowEmbedded and do the handling of the AGLContext yourself.
Hope that helps,
Stephan
(P.S. I am attaching a working example using an external window with
GraphicsWindowCarbon)
