QPropertyAnimation and QStackedLayout:functionality.

[savaliya_ambani]

yes, it comes here:
void widget::MenuEvent(int index)
{
}

The signal mapper is from the main widget. And when i take any menu page,i passed this *signalmapper into the class created for taking object of each menu page. And in that class it receives the refrence to the signalmapper and
mappes its own buttons with this signalmapper.

thats it.
only problem is that setCurrent Index has no effect.

Well last statement of mine: setCurrentIndex works well, so it is not a problem of Qt. Your syntax seems to be OK according to what you have said. But without real (not complete) code I can't help further, since my crystal ball is currently out of order, unfortunately.
