A mouse or touch event

The only difference with crate::platform::WindowEvent is that it uses untyped Point TODO: merge with platform::WindowEvent

Variants

Pressed

The mouse or finger was pressed

Fields

position: LogicalPoint

The position of the pointer when the event happened.

button: PointerEventButton

The button that was pressed.

click_count: u8

The current click count reported for this press.

touch_finger_id: i32

The touch ID if the event originated from touch input.

Released

The mouse or finger was released

Fields

position: LogicalPoint

The position of the pointer when the event happened.

button: PointerEventButton

The button that was released.

click_count: u8

The current click count reported for this release.

touch_finger_id: i32

The touch ID if the event originated from touch input.

Moved

The position of the pointer has changed

Fields

position: LogicalPoint

The new position of the pointer.

touch_finger_id: i32

The touch ID if the event originated from touch input.

Wheel

Wheel was operated.

Fields

position: LogicalPoint

The position of the pointer when the event happened.

delta_x: Coord

The horizontal scroll delta in logical pixels.

delta_y: Coord

The vertical scroll delta in logical pixels.

phase: TouchPhase

The gesture phase reported for the wheel event.

DragMove

The mouse is being dragged over this item. InputEventResult::EventIgnored means that the item does not handle the drag operation and InputEventResult::EventAccepted means that the item can accept it.

Fields

event: DropEvent

The dragged payload and its current position/proposed action.

allowed: AllowedDragActions

The actions the drag source permits.

Drop

The mouse is released while dragging over this item.

Fields

event: DropEvent

The dragged payload and its current position/proposed action.

allowed: AllowedDragActions

The actions the drag source permits.

PinchGesture

A platform-recognized pinch gesture (macOS/iOS trackpad, Qt).

Fields

position: LogicalPoint

The focal position of the gesture.

delta: f32

The incremental scale delta for this gesture update.

phase: TouchPhase

The gesture phase reported by the platform.

RotationGesture

A platform-recognized rotation gesture (macOS/iOS trackpad, Qt).

Fields

position: LogicalPoint

The focal position of the gesture.

delta: f32

The incremental rotation in degrees, where positive means clockwise.

phase: TouchPhase

The gesture phase reported by the platform.

Exit

The mouse exited the item or component

Implementations

impl MouseEvent

pub fn touch_finger_id(&self) -> i32
