<p>When you click inside the red square, the <a href="qml-qtquick-text.html">Text</a> type will list several properties of that click which are available to QML. The opacity of the red square will be reduced while the mouse is pressed and remains inside the <a href="qml-qtquick-mousearea.html">MouseArea</a>.</p>
<p>Signals are emitted by the <a href="qml-qtquick-mousearea.html">MouseArea</a> when clicks or other discrete operations occur within it.</p>
