The QSplitter class implements a splitter widget.
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 by a single splitter. The typical use of a QSplitter is to create several widgets and add them using insertWidget() or addWidget().
The following example will show a QListView, QTreeView, and QTextEdit side by side, with two splitter handles:
If a widget is already inside a QSplitter when insertWidget() or addWidget() is called, it will move to the new position. This can be used to reorder widgets in the splitter later. You can use indexOf(), widget(), and count() to get access to the widgets inside the splitter.
A default QSplitter lays out its children horizontally (side by side); you can use setOrientation(Qt::Vertical) to lay its children out vertically.
By default, all widgets can be as large or as small as the user wishes, between the minimumSizeHint() (or minimumSize()) and maximumSize() of the widgets.
QSplitter resizes its children dynamically by default. If you would rather have QSplitter resize the children only at the end of a resize operation, call setOpaqueResize(false).
The initial distribution of size between the widgets is determined by multiplying the initial size with the stretch factor. You can also use setSizes() to set the sizes of all the widgets. The function sizes() returns the sizes set by the user. Alternatively, you can save and restore the sizes of the widgets from a QByteArray using saveState() and restoreState() respectively.
When you hide() a child its space will be distributed among the other children. It will be reinstated when you show() it again.

Reimplemented Function
This method is also used to handle the situation where a widget is created with the splitter as a parent but not explicitly added with insertWidget() or addWidget(). This is for compatibility and not the recommended way of putting widgets into a splitter in new code. Please use insertWidget() or addWidget() in new code.

| void QSplitter::setSizes | ( | const QList< int > & | list | ) |
Sets the child widgets respective sizes to the values given in the list.
If the splitter is horizontal, the values set the widths of each widget in pixels, from left to right. If the splitter is vertical, the heights of each widget is set, from top to bottom.
Extra values in the list are ignored. If list contains too few values, the result is undefined but the program will still be well-behaved.
The overall size of the splitter widget is not affected. Instead, any additional/missing space is distributed amongst the widgets according to the relative weight of the sizes.
If you specify a size of 0, the widget will be invisible. The size policies of the widgets are preserved. That is, a value smaller then the minimal size hint of the respective widget will be replaced by the value of the hint.

| void QSplitter::setStretchFactor | ( | int | index, |
