Dear All,

I am developing a GUI application for the touch screen LCD,in that i am having some problems.

(1) i have QT-4.6.2 ,but it doesn't have QPropertyAnimation class.Where it has been released with this version.
(2) I am working with QStackedLayout and QTabWidget, so is there any requirement like tab key provided in keyboard, because i have developed a keyboard with the QSignalmapper class as per our requirement. So, i dont have any Tab key.
