 /*!
   \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().

   \enum KDGanttMinimizeSplitter::Direction
 
   The values of this enumeration describe into which direction the
   splitter will collapse its child widgets. By extension, it also
   specifies the orientation of the splitter; collapsing to the left or
   to the right results in a horizontal splitter, collapsing to the top
   or bottom in a vertical splitter.

   \fn Orientation KDGanttMinimizeSplitter::orientation() const

 /*! \enum KDGanttMinimizeSplitter::ResizeMode
 
   This enum type describes how KDGanttMinimizeSplitter will resize each of its child widgets.  The currently defined values are:
 
   Stretch: the widget will be resized when the splitter
   itself is resized.
 
   KeepSize: KDGanttMinimizeSplitter will try to keep this widget's size
   unchanged.
 
   FollowSizeHint: KDGanttMinimizeSplitter will resize the widget when the
   widget's size hint changes.
