availableGeometry() problem

[amrutap27]

Hi
I am using QApplication::desktop()->availableGeometry() function to get the width and available height of the screen. This function returns 320 by 240 when i call it first time form mainwindow whereas from second time onwards it gives correct value as 320 by 198.
How can i get correct value from its first call?! any suggestions regarding this please!
