   \class QSplitter qsplitter.h
   \brief The QSplitter class implements a splitter widget.
 
   \ingroup organizers
 
   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 QMultiLineEdit side by side:
 
   \code
     QSplitter *split = new QSplitter( parent );
     QListBox *lb = new QListBox( split );
     QListView *lv = new QListView( split );
     QMultiLineEdit *ed = new QMultiLineEdit( split );
   \endcode
 
   In QSplitter the boundary can be either horizontal or vertical.  The
   default is horizontal (the children are side by side) and you
   can use setOrientation( QSplitter::Vertical ) to set it to vertical.
 
   By default, all widgets can be as large or as small as the user
   wishes, down to \link QWidget::minimumSizeHint() minimumSizeHint()\endlink.
   You can naturally use setMinimumSize() and/or
   setMaximumSize() on the children. Use setResizeMode() to specify that
   a widget should keep its size when the splitter is resized.
 
   QSplitter normally resizes the children only at the end of a
   resize operation, but 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. When you show() it again, it will be reinstated.
