In KDGanttMinimizeSplitter, the boundary can be either horizontal or
vertical. The default is horizontal (the children are side by side)
but you can use setOrientation( QSplitter::Vertical ) to set it to
vertical.
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. It is also
possible to reorder the widgets within the splitter using
moveToFirst() and moveToLast().
