Application Resizing on Display resolution change

Hello all,

I have done a QT application with 320x240 as my application width and height with reference to my display. Now the display has changed 480x272 as resolution. How do i re-size my application automatically whenever there is a change.

Any command line parameter to re-size or something to do with the change in code.

Guide me.

Regards,
Augus
