<hr><a name="_details"></a><h2>Detailed Description</h2>
A container widget with resize handles between its children.
<p>
Provides a container in which widgets are laid out either horizontally (side by side, Horizontal orientation), or vertically (Vertical orientation).<p>
Widgets are separated by a <a class="el" href="classWt_1_1Ext_1_1SplitterHandle.html" title="A handle inside a splitter.">SplitterHandle</a> which the user may use to resize widgets. For this to work properly, you need to properly specify widths, and minimum- and maximum widths for the widgets:<p>
<ul>
<li>
They MUST have their width (or height) set using <a class="el" href="classWt_1_1WWidget.html#5bebad8f1582b8bebf01a9ed0ee11972" title="Resizes the widget.">WWidget::resize()</a>, in <a class="el" href="classWt_1_1WLength.html#908caf5d6be7e244e24598e6d22cd4c00b1fa4c1bd7adb92e1a04d62b96d30ba" title="Pixel, relative to canvas resolution.">WLength::Pixel</a> units. You cannot specify the size through CSS!<p>
</li>
<li>
Optionally, the may have a minimum width (or minimum height) set using <a class="el" href="classWt_1_1WWidget.html#092c7d1ecfde7f004ef120389d91775d" title="Sets a minimum size.">WWidget::setMinimumSize()</a> and <a class="el" href="classWt_1_1WWidget.html#f023064cf8007bda6baeb5277d79bbd9" title="Sets a maximum size.">WWidget::setMaximumSize()</a>. Again, you cannot specify these properties through CSS!<p>
</li>
<li>
Probably you will want to insert each widget in a <a class="el" href="classWt_1_1WScrollArea.html" title="A widget that adds scrolling capabilities to its content.">WScrollArea</a>, or set the CSS overflow attribute to hidden (which clips anything that goes outside) or auto (to add scroll bars). </li>
</ul>
<p>
<em>Note: removing or adding widgets after initial render is not yet supported.</em> <hr><h2>Member Function Documentation</h2>
