<h2>Detailed Description</h2>
<p>The QGroupBox widget provides a group box frame with a title.</p>
<p>A group box provides a frame, a title and a keyboard shortcut, and displays various other widgets inside itself. The title is on top, the keyboard shortcut moves keyboard focus to one of the group box's child widgets.</p>
<p>QGroupBox also lets you set the <a href="qgroupbox.html#title-prop">title</a> (normally set in the constructor) and the title's <a href="qgroupbox.html#alignment-prop">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>QGroupBox 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 QGroupBox with a layout:</p>
<pre> QGroupBox *groupBox = new QGroupBox(tr("Exclusive Radio Buttons"));
QRadioButton *radio1 = new QRadioButton(tr("&Radio button 1"));
QRadioButton *radio2 = new QRadioButton(tr("R&adio button 2"));
QRadioButton *radio3 = new QRadioButton(tr("Ra&dio button 3"));
radio1->setChecked(true);
QVBoxLayout *vbox = new QVBoxLayout;
vbox->addWidget(radio1);
vbox->addWidget(radio2);
vbox->addWidget(radio3);
vbox->addStretch(1);
groupBox->setLayout(vbox);</pre>

<h3 class="fn"><a name="alignment-prop"></a>alignment : <a href="qt.html#AlignmentFlag-enum">Qt::Alignment</a></h3>
<p>This property holds the alignment of the group box title.</p>
<p>Most styles place the title at the top of the frame. The horizontal alignment of the title can be specified using single values from the following list:</p>
<ul>
<li><a href="qt.html#AlignmentFlag-enum">Qt::AlignLeft</a> aligns the title text with the left-hand side of the group box.</li>
<li><a href="qt.html#AlignmentFlag-enum">Qt::AlignRight</a> aligns the title text with the right-hand side of the group box.</li>
<li><a href="qt.html#AlignmentFlag-enum">Qt::AlignHCenter</a> aligns the title text with the horizontal center of the group box.</li>
</ul>
<p>The default alignment is <a href="qt.html#AlignmentFlag-enum">Qt::AlignLeft</a>.</p>

<h3 class="fn"><a name="checkable-prop"></a>checkable : bool</h3>
<p>This property holds whether the group box has a checkbox in its title.</p>
<p>If this property is true, the group box displays its title using a checkbox in place of an ordinary label. If the checkbox is checked, the group box's children are enabled; otherwise they are disabled and inaccessible.</p>
<p>By default, group boxes are not checkable.</p>
<p>If this property is enabled for a group box, it will also be initially checked to ensure that its contents are enabled.</p>

<p>This property holds whether the group box is checked.</p>
<p>If the group box is checkable, it is displayed with a check box. If the check box is checked, the group box's children are enabled; otherwise the children are disabled and are inaccessible to the user.</p>
<p>By default, checkable group boxes are also checked.</p>

<h3 class="fn"><a name="flat-prop"></a>flat : bool</h3>
<p>This property holds whether the group box is painted flat or has a frame.</p>
<p>A group box usually consists of a surrounding frame with a title at the top. If this property is enabled, only the top part of the frame is drawn in most styles; otherwise the whole frame is drawn.</p>
<p>By default, this property is disabled; i.e. group boxes are not flat unless explicitly specified.</p>
<p><b>Note:</b> In some styles, flat and non-flat group boxes have similar representations and may not be as distinguishable as they are in other styles.</p>

<p>The group box title text will have a keyboard shortcut if the title contains an ampersand ('&') followed by a letter.</p>
<pre> g->setTitle("&User information");</pre>
<p>In the example above, <b>Alt+U</b> moves the keyboard focus to the group box. See the <a href="qshortcut.html#mnemonic">QShortcut</a> documentation for details (to display an actual ampersand, use '&&').</p>
