Enum PointerEvent

pub enum PointerEvent {
    Down {
        button: Option<PointerButton>,
        pointer: PointerInfo,
        state: PointerState,
    },
    Up {
        button: Option<PointerButton>,
        pointer: PointerInfo,
        state: PointerState,
    },
    Move(PointerUpdate),
    Cancel(PointerInfo),
    Enter(PointerInfo),
    Leave(PointerInfo),
    Scroll {
        pointer: PointerInfo,
        delta: ScrollDelta,
        state: PointerState,
    },
}

A standard PointerEvent.

This is intentionally limited to standard pointer events, and it is expected that applications and frameworks that support more event types will use this as a base and add what they need in a conversion.

Variants

Down

A PointerButton was pressed.

Fields

button: Option<PointerButton>

The PointerButton that was pressed..

pointer: PointerInfo

Identity of the pointer.

state: PointerState

The state of the pointer (i.e. position, pressure, etc.).

Up

A PointerButton was released.

Fields

button: Option<PointerButton>

The PointerButton that was released.

pointer: PointerInfo

Identity of the pointer.

state: PointerState

The state of the pointer (i.e. position, pressure, etc.).

Move(PointerUpdate)

Pointer moved.

Cancel(PointerInfo)

Pointer motion was cancelled.

Usually this is a touch which was taken over somewhere else. You should try to undo the effect of the gesture when you receive this.

Enter(PointerInfo)

Pointer entered the area that receives this event.

Leave(PointerInfo)

Pointer left the area that receives these events.

Scroll

A scroll was requested at the pointer location.

Usually this is caused by a mouse wheel or a touchpad.

Fields

pointer: PointerInfo

Identity of the pointer.

delta: ScrollDelta

The delta of the scroll.

state: PointerState

The state of the pointer (i.e. position, pressure, etc.).
