<h2 id="details">Detailed Description</h2>
</p>
<p class="centerAlign"><img src="images/qtquickcontrols2-button.gif" alt="" /></p><p>Button presents a push-button control that can be pushed or clicked by the user. Buttons are normally used to perform an action, or to answer a question. Typical buttons are <i>OK</i>, <i>Apply</i>, <i>Cancel</i>, <i>Close</i>, <i>Yes</i>, <i>No</i>, and <i>Help</i>.</p>
<p>A button emits the signal <a href="qml-qtquick-controls2-abstractbutton.html#clicked-signal">clicked()</a> when it is activated by the user. Connect to this signal to perform the button's action. Buttons also provide the signals <a href="qml-qtquick-controls2-abstractbutton.html#canceled-signal">canceled()</a>, <a href="qml-qtquick-controls2-abstractbutton.html#doubleClicked-signal">doubleClicked()</a>, <a href="qml-qtquick-controls2-abstractbutton.html#pressed-signal">pressed()</a>, <a href="qml-qtquick-controls2-abstractbutton.html#released-signal">released()</a> and <a href="qml-qtquick-controls2-abstractbutton.html#pressAndHold-signal">pressAndHold()</a> for long presses.</p>
<p>See the snippet below on how to connect to the button's signals.</p>
<pre class="cpp">

  RowLayout {
      Button {
          text: <span class="string">&quot;Ok&quot;</span>
          onClicked: model<span class="operator">.</span>submit()
      }
      Button {
          text: <span class="string">&quot;Cancel&quot;</span>
          onClicked: model<span class="operator">.</span>revert()
      }
