QGLWidget displayed only in QScrollArea

[zeller]

Hello

I have a custom QGLWidget that works fine standalone, and also if I embed it into a QScrollArea, but if I directly add it to the layout or embed it into a QWidget, it won't get displayed, it won't even take up its place in the UI. I call the resize after construction.
I tried it several ways but nothing worked (except the scrollarea)
My current code looks like this:
@
MapArea *wtf = new MapArea();
QWidget *sa = new QWidget();
QHBoxLayout *gl = new QHBoxLayout;
gl->addWidget(wtf);
sa->setLayout(gl);
wtf->resize(640, 480);
QTextEdit *te = new QTextEdit();
QGridLayout *centralPartLayout = new QGridLayout();
ui->widget->setLayout(centralPartLayout);
centralPartLayout->addWidget(sa, 1, 1);
wtf->update();
centralPartLayout->addWidget(te, 1, 2);
@

Please tell me how should I add the widget to the layout.

thanks
david

What do you mean by: "won't get displayed"?

I doesn't take up its place in the layout. Maybe the resize operation is ineffective.
On "this picture":http://borso.ole.hu/nogl.tiff it should be above the middle textedit

Check if the problem is with incorrect size policy.

Resizing the square in the grid after the QGLwidget was added solved the problem.
I called setColumnMinimumWidth and setRowMinimumHeight, but I don't know why is this needed...
