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>.

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.
