  \brief QSplitter 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.
