[maemo-developers] How to get kinetic scrolling working using Qt creator

[From: Sudheer K.]

Daniil,

Yes, both horizontal and vertical scrolling are working with your code. Now how do we get this to work in my case? :)

In my case, I have a scrollAreaWidgetContents (QWidget) 798 x 476 added to scrollArea. I can not resize this object using Qt creator. Even if I try to change the ui header file directly outside Qt creator, scrolling is not enabled. The group boxes which are added to scrollAreaWidgetContents have a combined height of more than 500.

I have no clue why this doesn't work, unless groupboxes and/or form layouts does not support scrolling.

The New Busy think 9 to 5 is a cute idea. Combine multiple calendars with Hotmail.
