I have found the reason why requestContinuousUpdate() is not been called
in my application (that is based on osgviewerWX example).
The osgviewerWX graphics window is derived from osgViewer::GraphicsWindow
(class GraphicsWindowWX : public wxGLCanvas, public
osgViewer::GraphicsWindow) and here I correctly add the
TrackballManipulator and tried to
override osgViewer::GraphicsWindow::requestContinuousUpdate() without
success.
That is because TrackballManipulator calls, when needed,
View::requestContinuousUpdate(). So obviously overriding
osgViewer::GraphicsWindow::requestContinuousUpdate(), as I was doing,
has no effect.
Now I created a class derived from osgViewer::Viewer and here I redefine
the function and this now works.
But this opens a question: which is the goal of adding a virtual
requestContinuousUpdate() to osgViewer::GraphicsWindow? Who calls it?
Thanks for your help!
