Thank you for the quick response! Here's a quite minimal example:
-----------------------------------------------------------------------------------------------
main.cpp:
-----------------------------------------------------------------------------------------------
#include <QApplication>
#include <QMainWindow>
#include <QGLWidget>
#include <QDebug>
static QGLFormat defaultFormat()
{
QGLFormat fmt;
fmt.setProfile( QGLFormat::CoreProfile );
fmt.setAlpha( true );
fmt.setSamples( 4 );
fmt.setSampleBuffers( true );
return fmt;
}
class Example : public QGLWidget
{
public:
Example(QWidget* parent) : QGLWidget( defaultFormat(), parent )
{
}
virtual void resizeGL( int w, int h )
{
qDebug() << w << "x" << h;
glViewport( 0, 0, w, h );
}
virtual void paintGL()
{
glClearColor(0.1f, 0.4f, 0.0f, 0.0f);
glClear(GL_COLOR_BUFFER_BIT);
}
virtual QSize sizeHint() const
{
return QSize(800, 600);
}
};
int main(int argc, char* argv[])
{
QApplication application(argc, argv);
QMainWindow window;
window.setWindowTitle("Example");
window.setCentralWidget(new Example(&window));
window.show();
return application.exec();
}
-----------------------------------------------------------------------------------------------
example.pro
-----------------------------------------------------------------------------------------------
QT += core gui opengl
TARGET = example
TEMPLATE = app
SOURCES += main.cpp
-----------------------------------------------------------------------------------------------
To test, I simply do a "vglconnect localhost" and "vglrun
./example". Using the above code, the window is resized to 800x600,
but the green frame is only very small in the top left corner.

Can you send me the source code for your widget?

There is still a resize issue: - When the window is resized, the overridden resize() handler of the GL widget even prints out the correct new window size and the camera/perspective changes accordingly - However, the rendered frame stays fixed at 640x480 resolution - Mouse coordinates within the OpenGL widget are also incorrect if the inherited widget size is not 640x480. VirtualGL version is 2.3.91 compiled from SVN trunk (accessed: Jan 16th 2015) with -DVGL-FAKEXCB=1. For better understanding, I’ve created two screen recordings: 1) Reference how it should behave: http://vis.uni-kl.de/~biedert/direct.ogv 2) Bug demonstration using a local vgl connection: http://vis.uni-kl.de/~biedert/vgl.ogv (Videos are in Theora video format; I use VLC for playback) Thank you very much for your support!
