Thanks Ian, I have studied that example but it does not give an answer.
What I'm trying accomplish is to have a MainWindow (derived from QApplication
/ QWidget) for user input, (buttons etc.) and then a
QWindow derived class as the OpenGL drawing surface and also to be the
centralwidget in the MainWindow . However, I haven't been
able to get this to work (probably because QWindow is not a QWidget based class
and thus won't be accepted as central*widget*). I
have read that there will be a QOpenGLWidget in future versions that may be
just what I'm after, but for now I'm trying to find out
if there is a workaround until that happens.
This is how I have been doing things so far, the myGLWidget is currently
QGLWidget based, and now I want/need to replace it with a
QWindow based class. The MainWindow constructor:
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent)
{
ui.setupUi(this);
glw = new myGLWidget();
setCentralWidget(glw);
glw->setAttribute( Qt::WA_DeleteOnClose );
...
}
All my OpenGL stuff is in the glw instance, using signals from MainWindow/user
controls but mouse input directly.
Thanks,
Risto
