Converting QWidget to QGLWidget in Qt Creator
(see title) I'm a newcomer to Qt and have read some tutorials online about using OpenGL with Qt. I found one that I cannot seem to find that renders to an openGl framebuffer that is then rendered to (what starts as) a QWidget. There was some step in making the QWidget a QGLWidget but I remember that it used the GUI designer to get the layout right etc... How does one go about doing this? Thanks!
I think you want the promotion feature in Designer:
- Drop a QWidget on your form
- Right click it and select "Promote to..."
** Base class name : QWidget
** Promoted class name: QGLWidget
** Header file: QGLWidget
** Global include: checked
- Click Add then Promote
Yes! This was it, thanks a lot!
