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. <img src=qsplitter-m.png> <img src=qsplitter-w.png> \sa QTabBar */ static QSize minSize( const QWidget *w ) { QSize min = w->minimumSize(); QSize s; if ( min.height() <= 0 || min.width() <= 0 ) s = w->minimumSizeHint(); if ( min.height() > 0 ) s.setHeight( min.height() ); if ( min.width() > 0 ) s.setWidth( min.width() ); return s.expandedTo(QSize(0,0)); } /*!
