How to change QWS_SIZE in qt application?

We usually export qt embedded environment variables like this:

export QWS_DISPLAY=[:]...[:]
export QWS_SIZE=800*600
export LD_LIBRARY_PATH=/usr/local/lib:$QTDIR/lib:$LD_LIBRARY_PATH

Now I hope QWS_SIZE will be changed in my application .In other words, I hope Qt application can control the framebuffer size . Can QWSServer::Geometry do it ? I failed . Thanks for any replies.

Solution

  • QWSServer widgets are not like QWidgets. One major philosophical difference is that you don't control them nearly as much. They are supplied to your application and are controlled by the environment.

    So the answer to your question is: no. The application doesn't control the framebuffer size, the device does.
