<p>A button with a label and/or icon, which may be standalone, or be added to a <a class="el" href="classWt_1_1Ext_1_1ToolBar.html" title="A class that represents a tool bar (or a menu bar).">ToolBar</a> (see <a class="el" href="classWt_1_1Ext_1_1ToolBar.html#aa0384abdeff4e404676bfbd872599d48" title="Add a button with given text.">ToolBar::addButton()</a>) or to a <a class="el" href="classWt_1_1Ext_1_1Dialog.html" title="A dialog emulates a modal window that blocks the user-interface.">Dialog</a> (see <a class="el" href="classWt_1_1Ext_1_1Dialog.html#ad9f19a8ff62e3520544f2ea10a7647ce" title="Add a button at the bottom of this dialog.">Dialog::addButton()</a>).</p>
<p>The API is similar to the <a class="el" href="classWt_1_1WPushButton.html" title="A widget that represents a push button.">WPushButton</a> API, with the following additional features: </p>
<ul>
<li>
an icon may be specified using <a class="el" href="classWt_1_1Ext_1_1AbstractButton.html#ab484de8e4b543aa36ef5bfd1c8b70548" title="Set the item icon path.">AbstractButton::setIcon()</a>; </li>
<li>
the button may be configured as a toggle button (see <a class="el" href="classWt_1_1Ext_1_1AbstractButton.html#afe7d30546234065316df73026558fc79" title="Set if the item is checkable.">AbstractButton::setCheckable()</a>; </li>
<li>
