i using python 3.3 pyqt4. when making gui, asking user enter specific details using multiple popup dialog boxes within function, when nothing entered box accept such value, instead of asking user reenter. there option close dialog box (the exit button in top right), when clicked next dialog box run instead of stop entire function. want dialog boxes stop running when exit button activated, , dialog box not allow no vlaues being entered. if other information needed please let me know.

use form gathering information. can have dialog code below. code might not need, sure point right direction.
