| | | | | | | | | | |	1) Use QFormLayout instead of QGridLayout 2) Remove Symbian specific size hack 3) Give button box a parent, so that it's buttons get properly added as the dialog's softkeys. 4) Add submitButton with a positive button role Task-number: QTBUG-5685 Reviewed-by: Jason Barron
*	showMaximized() lets us see SoftKeys	Alessandro Portale	2009-11-17	1	-2/+2
| | | | | | | |	The current implementation would not show Softkeys as long as we show a widget via showFullScreen. Therefore, on Symbian we will for now use showMaximized Reviewed-By: Jason Barron

| | | | | | | | | |	Added a line to the symbianpkgrules.pri files which includes an ICON if the TARGET.UID3 is defined. We should fix the application_icon.prf to handle ICON without UID3 situations more gracefully, but for now I reordered existing UID3s to be specified before the symbianpkgrules.pri includes.
