<hr><h2><a name="details"></a>Detailed Description</h2>
The QSplitter class implements a splitter widget.
<p>
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.
<p>To show a <a href="qlistbox.html">QListBox</a>, a <a href="qlistview.html">QListView</a> and a <a href="qmultilineedit.html">QMultiLineEdit</a> side by side:
<p><pre> <a href="qsplitter.html">QSplitter</a> *split = new <a href="qsplitter.html">QSplitter</a>( parent );
<a href="qlistbox.html">QListBox</a> *lb = new <a href="qlistbox.html">QListBox</a>( split );
<a href="qlistview.html">QListView</a> *lv = new <a href="qlistview.html">QListView</a>( split );
<a href="qmultilineedit.html">QMultiLineEdit</a> *ed = new <a href="qmultilineedit.html">QMultiLineEdit</a>( split );
</pre>
<p>In QSplitter the boundary can be either horizontal or vertical. The
default is horizontal (the children are side by side) and you
can use <a href="#5ae208">setOrientation</a>( QSplitter::Vertical ) to set it to vertical.
<p>By default, all widgets can be as large or as small as the user
wishes, down to <a href="qwidget.html#553e08">minimumSizeHint()</a>.
You can naturally use <a href="qwidget.html#c0b5fb">setMinimumSize</a>() and/or
<a href="qwidget.html#c78dce">setMaximumSize</a>() on the children. Use <a href="#33bf83">setResizeMode</a>() to specify that
a widget should keep its size when the splitter is resized.
<p>QSplitter normally resizes the children only at the end of a
resize operation, but if you call <a href="#28096e">setOpaqueResize</a>( TRUE ), the
widgets are resized as often as possible.
<p>The initial distribution of size between the widgets is determined
by the initial size of each widget. You can also use <a href="#8fd8cf">setSizes</a>() to
set the sizes of all the widgets. The function <a href="#cf6c00">sizes</a>() returns the
sizes set by the user.
<p>If you <a href="qwidget.html#410481">hide</a>() a child, its space will be distributed among the other
children. When you <a href="qwidget.html#200ee5">show</a>() it again, it will be reinstated.

<hr><h2>Member Type Documentation</h2>
<h3 class="fn"><a name="ResizeMode">QSplitter::ResizeMode</a></h3>
This enum type describes how QSplitter will resize each of its child widgets. The currently defined values are: <ul>
<li> <code>Stretch</code> - the widget will be resized when the splitter
itself is resized.
<li> <code>KeepSize</code> - QSplitter will try to keep this widget's size
unchanged.
<li> <code>FollowSizeHint</code> - QSplitter will resize the widget when its
size hint changes.
<p></ul>
