Add OpenGl window to the grid layout of the child qwidget.

[pastispast]

Hi Friends,

I am facing some problem while adding the opengl window to the child qwidget. I have:

- Parent qwidget.
- 1 grid layout
- 1 opengl window
- 1 child qwidget (of parent qwidget).

1'st I am adding the opengl window to the gridlayout then I am adding the gridlayout to the child qwidget. But I did not get any view (also paintGl is not calling, if by how I call paintGl then also I am not getting the view)

Note: If I directly set the layout to the parent qwidget then I got the open gl window.

What I am missing here??? I have attached my example along with this post.

Thank you very much...OpenGlTest.zip

Create a layout and add the dummy frame to it as well. Your dummy frame probably has a QSize(0,0).

IntegrateDraw::IntegrateDraw(QWidget *parent): QWidget(parent)
{
	//OpenGL object
	oGlDraw = new OpenGlDraw();
 
	//QWidget
	dummyFrame = new QWidget(this);
	//dummyFrame->setWindowFlags( Qt::Dialog); //Point 3
 
	//Grid layout
	gLayout = new QGridLayout();
	gLayout->addWidget(oGlDraw);
 
	//setLayout(gLayout);
	dummyFrame->setLayout(gLayout);
 
	// this does it:
	QGridLayout *l = new QGridLayout;
	l->addWidget(dummyFrame);
	setLayout(l);
};

IntegrateDraw::IntegrateDraw(QWidget *parent): QWidget(parent)
{
	//OpenGL object
	oGlDraw = new OpenGlDraw();

	//QWidget
	dummyFrame = new QWidget(this);
	//dummyFrame->setWindowFlags( Qt::Dialog); //Point 3

	//Grid layout
	gLayout = new QGridLayout();
	gLayout->addWidget(oGlDraw);

	//setLayout(gLayout);
	dummyFrame->setLayout(gLayout);

	// this does it:
	QGridLayout *l = new QGridLayout;
	l->addWidget(dummyFrame);
	setLayout(l);
};
