<h2 id="details">Detailed Description</h2>
</p>
<p class="centerAlign"><img src="images/groupbox.png" alt="" /></p><p>A group box provides a frame, a title on top and displays various other controls inside itself. Group boxes can also be checkable.</p>
<p>Child controls in checkable group boxes are enabled or disabled depending on whether or not the group box is checked.</p>
<p>You can minimize the space consumption of a group box by enabling the flat property. In most styles, enabling this property results in the removal of the left, right and bottom edges of the frame.</p>
<p>To add content to a group box, you can reparent it to its <a href="qml-qtquick-controls-groupbox.html#contentItem-prop">contentItem</a> property.</p>
<p>The implicit size of the <a href="qml-qtquick-controls-groupbox.html">GroupBox</a> is calculated based on the size of its content. If you want to anchor items inside the group box, you must specify an explicit width and height on the <a href="qml-qtquick-controls-groupbox.html">GroupBox</a> itself.</p>
<p>The following example shows how we use a <a href="qml-qtquick-controls-groupbox.html">GroupBox</a>:</p>
<pre class="qml"><span class="type"><a href="qml-qtquick-controls-groupbox.html">GroupBox</a></span> {
    <span class="name">title</span>: <span class="string">&quot;Joining for?&quot;</span>

    <span class="type"><a href="../qtquick/qml-qtquick-column.html">Column</a></span> {
        <span class="name">spacing</span>: <span class="number">10</span>

        <span class="type"><a href="qml-qtquick-controls-checkbox.html">CheckBox</a></span> {
            <span class="name">text</span>: <span class="string">&quot;Breakfast&quot;</span>
            <span class="name">checked</span>: <span class="number">true</span>
        }
        <span class="type"><a href="qml-qtquick-controls-checkbox.html">CheckBox</a></span> {
            <span class="name">text</span>: <span class="string">&quot;Lunch&quot;</span>
            <span class="name">checked</span>: <span class="number">false</span>
        }
        <span class="type"><a href="qml-qtquick-controls-checkbox.html">CheckBox</a></span> {
            <span class="name">text</span>: <span class="string">&quot;Dinner&quot;</span>
            <span class="name">checked</span>: <span class="number">true</span>
        }
    }
}</pre>

<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, so group boxes are not flat unless explicitly specified.</p>
