Struct PrimaryPointerState 

pub struct PrimaryPointerState { /* private fields */ }

A stateful view of the primary pointer.

Implementations

impl PrimaryPointerState

pub fn is_just_pressed(&self, button: PointerButton) -> bool

Return true if the button was pressed within the last frame.

This corresponds to having received a PointerEvent::Down event for that button on the primary pointing device.

pub fn is_just_released(&self, button: PointerButton) -> bool

Return true if the button was released within the last frame.

This corresponds to having received a PointerEvent::Up event for that button on the primary pointing device.

pub fn is_auxiliary_just_pressed(&self) -> bool

Return true if the Auxiliary button (usually middle mouse) was pressed within the last frame.

pub fn is_auxiliary_just_released(&self) -> bool

Return true if the Auxiliary button was released within the last frame.

pub fn is_primary_just_pressed(&self) -> bool

Return true if the Primary button (usually left mouse) was pressed within the last frame.

pub fn is_primary_just_released(&self) -> bool

Return true if the Primary button was released within the last frame.

pub fn is_secondary_just_pressed(&self) -> bool

Return true if the Secondary button (usually right mouse) was pressed within the last frame.

pub fn is_secondary_just_released(&self) -> bool

Return true if the Secondary button was released within the last frame.

pub fn is_any_down(&self) -> bool

Return true if any button is currently held down.

pub fn is_down(&self, button: PointerButton) -> bool

Return true if the specified button is currently held down.

pub fn clear_frame(&mut self)

Clear the per-frame state to prepare for a new frame.

pub fn current_position(&self) -> PhysicalPosition<f64>

Current position.

This will only give known positions.

pub fn current_logical_position(&self) -> LogicalPosition<f64>

Current position (in logical units).

This will only give known positions.

pub fn motion(&self) -> PhysicalPosition<f64>

Relative motion this frame.

pub fn logical_motion(&self) -> LogicalPosition<f64>

Relative motion this frame.

pub fn process_pointer_event(&mut self, event: PointerEvent)

Update the state based on the given pointer event.

Only events from the primary pointer are processed. Press and release events update the just_pressed, just_released, and down states.
