Use setResizeMode() to specify that a widget should keep its size when the splitter is resized. Although KDGanttMinimizeSplitter normally resizes the children only at the end of a resize operation, if you call setOpaqueResize( TRUE ) the widgets are resized as often as possible. The initial distribution of size between the widgets is determined by the initial size of each widget. You can also use setSizes() to set the sizes of all the widgets. The function sizes() returns the sizes set by the user. If you hide() a child, its space will be distributed among the other children. It will be reinstated when you show() it again.
