 /*!
   \class KDGanttMinimizeSplitter KDGanttMinimizeSplitter.h
   \brief The KDGanttMinimizeSplitter class implements a splitter
   widget with minimize buttons.
 
   This class (and its documentation) is largely a copy of Qt's
   QSplitter; the copying was necessary because QSplitter is not
   extensible at all. QSplitter and its documentation are licensed
   according to the GPL and the Qt Professional License (if you hold
   such a license) and are (C) Trolltech AS.
 
   A splitter lets the user control the size of child widgets by
   dragging the boundary between the children. Any number of widgets
   may be controlled.
 
   To show a QListBox, a QListView and a QTextEdit side by side:
 
   \code
     KDGanttMinimizeSplitter *split = new KDGanttMinimizeSplitter( parent );
     QListBox *lb = new QListBox( split );
     QListView *lv = new QListView( split );
     QTextEdit *ed = new QTextEdit( split );
   \endcode
 
   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().
