<!-- $$$QSplitter-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QSplitter class implements a splitter widget.</p>
<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 by a single splitter. The typical use of a QSplitter is to create several widgets and add them using <a href="qsplitter.html#insertWidget">insertWidget</a>() or <a href="qsplitter.html#addWidget">addWidget</a>().</p>
<p>The following example will show a <a href="qlistview.html">QListView</a>, <a href="qtreeview.html">QTreeView</a>, and <a href="qtextedit.html">QTextEdit</a> side by side, with two splitter handles:</p>
<pre class="cpp"> <span class="type">QSplitter</span> <span class="operator">*</span>splitter <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QSplitter</span>(parent);
<span class="type"><a href="qlistview.html">QListView</a></span> <span class="operator">*</span>listview <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qlistview.html">QListView</a></span>;
<span class="type"><a href="qtreeview.html">QTreeView</a></span> <span class="operator">*</span>treeview <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qtreeview.html">QTreeView</a></span>;
<span class="type"><a href="qtextedit.html">QTextEdit</a></span> <span class="operator">*</span>textedit <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qtextedit.html">QTextEdit</a></span>;
splitter<span class="operator">-</span><span class="operator">></span>addWidget(listview);
splitter<span class="operator">-</span><span class="operator">></span>addWidget(treeview);
splitter<span class="operator">-</span><span class="operator">></span>addWidget(textedit);</pre>
<p>If a widget is already inside a QSplitter when <a href="qsplitter.html#insertWidget">insertWidget</a>() or <a href="qsplitter.html#addWidget">addWidget</a>() is called, it will move to the new position. This can be used to reorder widgets in the splitter later. You can use <a href="qsplitter.html#indexOf">indexOf</a>(), <a href="qsplitter.html#widget">widget</a>(), and <a href="qsplitter.html#count">count</a>() to get access to the widgets inside the splitter.</p>
<p>A default QSplitter lays out its children horizontally (side by side); you can use setOrientation(<a href="qt.html#Orientation-enum">Qt::Vertical</a>) to lay its children out vertically.</p>
<p>By default, all widgets can be as large or as small as the user wishes, between the <a href="qsplitter.html#minimumSizeHint">minimumSizeHint</a>() (or <a href="qwidget.html#minimumSize-prop">minimumSize</a>()) and <a href="qwidget.html#maximumSize-prop">maximumSize</a>() of the widgets.</p>
<p>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).</p>
<p>The initial distribution of size between the widgets is determined by multiplying the initial size with the stretch factor. You can also use <a href="qsplitter.html#setSizes">setSizes</a>() to set the sizes of all the widgets. The function <a href="qsplitter.html#sizes">sizes</a>() returns the sizes set by the user. Alternatively, you can save and restore the sizes of the widgets from a <a href="qbytearray.html">QByteArray</a> using <a href="qsplitter.html#saveState">saveState</a>() and <a href="qsplitter.html#restoreState">restoreState</a>() respectively.</p>
<p>When you <a href="qwidget.html#hide">hide</a>() a child its space will be distributed among the other children. It will be reinstated when you <a href="qwidget.html#show">show</a>() it again.</p>

<p>Restores the splitter's layout to the <i>state</i> specified. Returns true if the state is restored; otherwise returns false.</p>
<p>Typically this is used in conjunction with <a href="qsettings.html">QSettings</a> to restore the size from a past session. Here is an example:</p>

<h3 class="fn"><a name="saveState"></a><span class="type"><a href="qbytearray.html">QByteArray</a></span> QSplitter::<span class="name">saveState</span> () const</h3>
<p>Saves the state of the splitter's layout.</p>
<p>Typically this is used in conjunction with <a href="qsettings.html">QSettings</a> to remember the size for a future session. A version number is stored as part of the data. Here is an example:</p>
<pre class="cpp"> <span class="type"><a href="qsettings.html">QSettings</a></span> settings;
settings<span class="operator">.</span>setValue(<span class="string">"splitterSizes"</span><span class="operator">,</span> splitter<span class="operator">-</span><span class="operator">></span>saveState());</pre>

<p>Sets whether the child widget at index <i>index</i> is collapsible to <i>collapse</i>.</p>
<p>By default, children are collapsible, meaning that the user can resize them down to size 0, even if they have a non-zero <a href="qwidget.html#minimumSize-prop">minimumSize</a>() or <a href="qsplitter.html#minimumSizeHint">minimumSizeHint</a>(). This behavior can be changed on a per-widget basis by calling this function, or globally for all the widgets in the splitter by setting the <a href="qsplitter.html#childrenCollapsible-prop">childrenCollapsible</a> property.</p>
<p><b>See also </b><a href="qsplitter.html#isCollapsible">isCollapsible</a>() and <a href="qsplitter.html#childrenCollapsible-prop">childrenCollapsible</a>.</p>

<h3 class="fn"><a name="setRubberBand"></a><span class="type">void</span> QSplitter::<span class="name">setRubberBand</span> ( <span class="type">int</span> <i>pos</i> )<tt> [protected]</tt></h3>
<p>Displays a rubber band at position <i>pos</i>. If <i>pos</i> is negative, the rubber band is removed.</p>
<!-- @@@setRubberBand -->
<!-- $$$setSizes[overload1]$$$setSizesconstQList<int>& -->
<h3 class="fn"><a name="setSizes"></a><span class="type">void</span> QSplitter::<span class="name">setSizes</span> ( const <span class="type"><a href="qlist.html">QList</a></span><<span class="type">int</span>> & <i>list</i> )</h3>
<p>Sets the child widgets respective sizes to the values given in the <i>list</i>.</p>
<p>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.</p>
<p>Extra values in the <i>list</i> are ignored. If <i>list</i> contains too few values, the result is undefined but the program will still be well-behaved.</p>
<p>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.</p>
<p>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.</p>

<!-- $$$setStretchFactor[overload1]$$$setStretchFactorintint -->
<h3 class="fn"><a name="setStretchFactor"></a><span class="type">void</span> QSplitter::<span class="name">setStretchFactor</span> ( <span class="type">int</span> <i>index</i>, <span class="type">int</span> <i>stretch</i> )</h3>
<p>Updates the size policy of the widget at position <i>index</i> to have a stretch factor of <i>stretch</i>.</p>
<p><i>stretch</i> is not the effective stretch factor; the effective stretch factor is calculated by taking the initial size of the widget and multiplying it with <i>stretch</i>.</p>
<p>This function is provided for convenience. It is equivalent to</p>

<h3 class="fn"><a name="sizes"></a><span class="type"><a href="qlist.html">QList</a></span><<span class="type">int</span>> QSplitter::<span class="name">sizes</span> () const</h3>
<p>Returns a list of the size parameters of all the widgets in this splitter.</p>
<p>If the splitter's orientation is horizontal, the list contains the widgets width in pixels, from left to right; if the orientation is vertical, the list contains the widgets height in pixels, from top to bottom.</p>
<p>Giving the values to another splitter's <a href="qsplitter.html#setSizes">setSizes</a>() function will produce a splitter with the same layout as this one.</p>
<p>Note that invisible widgets have a size of 0.</p>

<p>This signal is emitted when the splitter handle at a particular <i>index</i> has been moved to position <i>pos</i>.</p>
<p>For right-to-left languages such as Arabic and Hebrew, the layout of horizontal splitters is reversed. <i>pos</i> is then the distance from the right edge of the widget.</p>
