problem with displaying QGLWidget in QWidget made in desinger

[yasirsaleem]

hi dear,
I am using qt 4.7.1 and qt-creator 2.0.1. I have made a qglwidget.h and qglwidget.cpp. Then I made a widget in designer, right click it, selected promote to, then in base class I select "QWidget", in Promoted class name I wrote QGLWidget and in header file I wrote qglwidget.h
Now the problem is that how can I display my qglwidet.cpp code in the widget, which I made through designer. When I run my project the widget (to which I promote qtwidget) is displaying a black screen.
Kindly tell me that how can I display my code in that widget.

Thank you very much

Have you read the QGLWidget docs ? You need to put your OpenGL code in paintGL(), initializeGL() and resizeGL() methods (there is an example in documentation).

yes, I have already written my code in these functions. And if I create a new instance of qglwidet instance then it works fine. The problem is that how should I show it in widget made in desinger

in Promoted class name I wrote QGLWidget

Ok, so this is the problem - you need to provide your WidgetClassName instead of QGLWidget, because now you are adding default QGLWidget to your ui.

I have made a qglwidget.h and qglwidget.cpp

I'd also suggest changing your file names.

Thank you so much. My problem has been solved by changing my filenames.
