<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qgroupbox.html">QGroupBox</a> widget provides a group box frame with a title.</p>
<p class="centerAlign"><img src="images/windows-groupbox.png" alt="" /></p><p>A group box provides a frame, a title on top, a keyboard shortcut, and displays various other widgets inside itself. The keyboard shortcut moves keyboard focus to one of the group box's child widgets.</p>
<p><a href="qgroupbox.html">QGroupBox</a> also lets you set the <a href="qgroupbox.html#title-prop">title</a> (normally set in the constructor) and the title's <a href="stylesheet-reference.html#alignment">alignment</a>. Group boxes can be <a href="qgroupbox.html#checkable-prop">checkable</a>. Child widgets in checkable group boxes are enabled or disabled depending on whether or not the group box is <a href="qgroupbox.html#checked-prop">checked</a>.</p>
<p>You can minimize the space consumption of a group box by enabling the <a href="qgroupbox.html#flat-prop">flat</a> property. In most <a href="qstyle.html">styles</a>, enabling this property results in the removal of the left, right and bottom edges of the frame.</p>
<p><a href="qgroupbox.html">QGroupBox</a> doesn't automatically lay out the child widgets (which are often <a href="qcheckbox.html">QCheckBox</a>es or <a href="qradiobutton.html">QRadioButton</a>s but can be any widgets). The following example shows how we can set up a <a href="qgroupbox.html">QGroupBox</a> with a layout:</p>
