Enum PointerDeviceKind 

pub enum PointerDeviceKind {
    Touch,
    Mouse,
    Stylus,
    InvertedStylus,
    Trackpad,
    Unknown,
}

The kind of pointer device.

Variants

Touch

A touch-based pointer device.

The most common case is a touch screen.

When the user is operating with a trackpad on iOS, clicking will also dispatch events with kind Touch if UIApplicationSupportsIndirectInputEvents is not present in Info.plist or returns NO.

See also:

• UIApplicationSupportsIndirectInputEvents.

Mouse

A mouse-based pointer device.

The most common case is a mouse on the desktop or Web.

When the user is operating with a trackpad on iOS, moving the pointing cursor will also dispatch events with kind Mouse, and clicking will dispatch events with kind Mouse if UIApplicationSupportsIndirectInputEvents is not present in Info.plist or returns NO.

• UIApplicationSupportsIndirectInputEvents.

Stylus

A pointer device with a stylus.

InvertedStylus

A pointer device with a stylus that has been inverted.

Trackpad

Gestures from a trackpad.

A trackpad here is defined as a touch-based pointer device with an indirect surface (the user operates the screen by touching something that is not the screen).

When the user makes zoom, pan, scroll or rotate gestures with a physical trackpad, supporting platforms dispatch events with kind Trackpad.

Events with kind Trackpad can only have a PointerChange of Add, Remove, and pan-zoom related values.

Some platforms don’t support (or don’t fully support) trackpad gestures, and might convert trackpad gestures into fake pointer events that simulate dragging. These events typically have kind Touch or Mouse instead of Trackpad. This includes (but is not limited to) Web, and iOS when UIApplicationSupportsIndirectInputEvents isn’t present in Info.plist or returns NO.

Moving the pointing cursor or clicking with a trackpad typically triggers Touch or Mouse events, but never triggers Trackpad events.

Unknown

An unknown pointer device.
