MOUSE_WHEEL_EVENT arguments.

Fields§

§timestamp: DInstant

Instant the event happened.

§window_id: WindowId

Id of window that received the event.

§device_id: DeviceId

Id of device that generated the event.

§position: DipPoint

Position of the mouse in the coordinates of target.

§modifiers: ModifiersState

What modifier keys where pressed when this event happened.

§delta: MouseScrollDelta

Wheel motion delta, value is in pixels if the wheel is a touchpad.

§phase: TouchPhase

Implementations§

source§

impl MouseWheelArgs

source

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, position: impl Into<DipPoint>, modifiers: impl Into<ModifiersState>, delta: impl Into<MouseScrollDelta>, phase: impl Into<TouchPhase>, hits: impl Into<HitTestInfo>, target: impl Into<InteractionPath>, ) -> Self

New args from values that convert into the argument types.

source

pub fn now( window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, position: impl Into<DipPoint>, modifiers: impl Into<ModifiersState>, delta: impl Into<MouseScrollDelta>, phase: impl Into<TouchPhase>, hits: impl Into<HitTestInfo>, target: impl Into<InteractionPath>, ) -> Self

Arguments for event that happened now (INSTANT.now).

source§

impl MouseWheelArgs

source

pub fn shifted_delta(&self) -> MouseScrollDelta

Swaps the delta axis if modifiers contains SHIFT.

source

pub fn is_scroll(&self) -> bool

If the modifiers allow the event to be used for scrolling.

Is true if only SHIFT, ALT or none modifiers are pressed. If true the scroll_delta method returns a value.

source

pub fn scroll_delta( &self, alt_factor: impl Into<Factor>, ) -> Option<MouseScrollDelta>

Returns the delta for a scrolling operation, depending on the modifiers.

If ALT is pressed scales the delta by alt_factor, then, if no more modifiers are pressed returns the scaled delta, if only SHIFT is pressed returns the swapped delta, otherwise returns None.

source

pub fn is_zoom(&self) -> bool

If the modifiers allow the event to be used for zooming.

Is true if only CTRL is pressed. If true the zoom_delta method returns a value.

source

pub fn zoom_delta(&self) -> Option<MouseScrollDelta>

Returns the delta for a zoom-in/out operation, depending on the modifiers.

If only CTRL is pressed returns the delta, otherwise returns None.

source

pub fn is_enabled(&self, widget_id: WidgetId) -> bool

Returns true if the widget is enabled in target.

source

pub fn is_disabled(&self, widget_id: WidgetId) -> bool

Returns true if the widget is disabled in target.

source

pub fn position_wgt(&self) -> Option<PxPoint>

Gets position in the widget inner bounds.
