When you click inside the red square, the Text 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 MouseArea.
Signals are emitted by the MouseArea when clicks or other discrete operations occur within it.
onPressAndHold: btn.text = 'Press and hold' onClicked: (mouse) => { btn.text = 'Clicked (wasHeld=' + mouse.wasHeld + ')' } onDoubleClicked: btn.text = 'Double clicked'
MouseArea can also be used to drag items around. By setting the parameters of the drag property, the target item will be dragged around if the user starts to drag within the mouse area boundary.
