[Qt-interest] QGLWidget with text - zoom in / zoom out

[_h_]

Hi,
I need the zoom in/out facility in QGLWidget, which has text drawn on
it with other primitives.
When I zoom in/out the primitives get minimized/maximized but the text
remains at the same size. I want to have text size should
reduce/increate with zoom in/out. The only way I can think is to
increase/decrease the text size based on the zoom, is it right
solution?
Thank you.
