qglwidget and printing
Message 1 in thread
Hi,
does anyone of you have an idea how to print the contents of opengl
widget? I suppose that it is not so straightforward as in the case of
standard canvas. Or am I wrong?
thx

Get the contents using either QGLWidget::renderPixmap or grabFrameBuffer,
and print them:
http://doc.trolltech.com/4.1/qglwidget.html#renderPixmap
http://doc.trolltech.com/4.1/qglwidget.html#grabFrameBuffer
renderPixmap is usually better for this purpose, as you can this way
generate a high resolution image.
