+/*!
+  \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().
