A PointerEvent is an event describing contact or movement across a surface, provided by a mouse, a touchpoint (single finger on a touchscreen), or a stylus on a graphics tablet. The device property provides more information about where the event came from.

[read-only] button : enumeration |
|
[read-only] buttons : int |
This property holds the combination of mouse or stylus buttons pressed when the event was generated. For move events, this is all buttons that are pressed down. For press events, this includes the button that caused the event, as well as any others that were already held. For release events, this excludes the button that caused the event.

[read-only] device : PointerDevice |
This property holds the device that generated the event.
|
[read-only] modifiers : int |
This property holds the keyboard modifier flags that existed immediately before the event occurred.
It contains a bitwise combination of the following flags:
| Constant | Description |
|---|---|
Qt.NoModifier |
No modifier key is pressed. |
Qt.ShiftModifier |
A Shift key on the keyboard is pressed. |
Qt.ControlModifier |
A Ctrl key on the keyboard is pressed. |
Qt.AltModifier |
An Alt key on the keyboard is pressed. |
Qt.MetaModifier |
A Meta key on the keyboard is pressed. |
Qt.KeypadModifier |

For example, to react to a Shift key + Left mouse button click:
Item { TapHandler { onTapped: { if ((event.button == Qt.LeftButton) && (event.modifiers & Qt.ShiftModifier)) doSomething(); } } }
