QT application with opengl drops xorg session

[YuriyRusinov]

Hello, colleagues !

I try to develop qt application with opengl support. I put QGLWidget subclass object onto QMainWindow. But sometimes on resize or exit event xorg user session is terminated and I drop on login manager.

Here is my glwidget realization.

#include "glwidget.h"
 
GLWidget :: GLWidget (QWidget *parent, Qt::WFlags f)
    : QGLWidget (parent, 0, f)
{
}
 
GLWidget :: ~GLWidget (void)
{
}
 
void GLWidget :: initializeGL (void)
{
}
 
void GLWidget :: paintGL (void)
{
}
 
void GLWidget :: resizeGL (int width, int height)
{
}

#include "glwidget.h"

GLWidget :: GLWidget (QWidget *parent, Qt::WFlags f)
    : QGLWidget (parent, 0, f)
{
}

GLWidget :: ~GLWidget (void)
{
}

void GLWidget :: initializeGL (void)
{
}

void GLWidget :: paintGL (void)
{
}

void GLWidget :: resizeGL (int width, int height)
{
}

My OS is Gentoo Linux 2008.0. Any ideas.

Check your OpenGL drivers.
