\class KDGanttSemiSizingControl KDGanttSemiSizingControl.h

This class provides exactly one child widget with a button for
|
|
minimizing and restoring. You can also specify a so-called minimize
|
|
widget that will be shown in place of the child widget while the
|
|
latter one is minimized. While the child widget is not minimized,
|
|
the minimize widget will not be visible.
|
|
|
|
If you add more than one child widget (besides the minimize widget),
|
|
only the last one added will be visible.
