54 HbWidgetBase is optimized to work with layout. ParentWidget is always reponsible |
|
55 of layouting its children. If widget doesnot have a layout than it is responsible for |
|
56 taking care of it's children geometries.HbWidgetBase doesnot guarantee that adjustSize will |
|
57 be called before widget is shown. |
