WINDOW_CHANGED_EVENT args.

Fields

timestamp: DInstant

Instant the event happened.

window_id: WindowId

Window that has moved, resized or has a state change.

state: Option<(WindowState, WindowState)>

Window state change, if it has changed the values are (prev, new) states.

position: Option<(PxPoint, DipPoint)>

New window position if it was moved.

The values are (global_position, actual_position) where the global position is in the virtual space that encompasses all monitors and actual position is in the monitor space.

size: Option<DipSize>

New window size if it was resized.

cause: EventCause

If the app or operating system caused the change.

Implementations

impl WindowChangedArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, window_id: impl Into<WindowId>, state: impl Into<Option<(WindowState, WindowState)>>, position: impl Into<Option<(PxPoint, DipPoint)>>, size: impl Into<Option<DipSize>>, cause: impl Into<EventCause>, ) -> Self

New args from values that convert into the argument types.

pub fn now( window_id: impl Into<WindowId>, state: impl Into<Option<(WindowState, WindowState)>>, position: impl Into<Option<(PxPoint, DipPoint)>>, size: impl Into<Option<DipSize>>, cause: impl Into<EventCause>, ) -> Self

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

impl WindowChangedArgs

pub fn is_state_changed(&self) -> bool

Returns true if this event represents a window state change.

pub fn prev_state(&self) -> Option<WindowState>

Returns the previous window state if it has changed.

pub fn new_state(&self) -> Option<WindowState>

Returns the new window state if it has changed.

pub fn entered_state(&self, state: WindowState) -> bool

Returns true if new_state is state and prev_state is not.

pub fn exited_state(&self, state: WindowState) -> bool

Returns true if prev_state is state and new_state is not.

pub fn entered_fullscreen(&self) -> bool

Returns true if new_state is one of the fullscreen states and prev_state is not.

pub fn exited_fullscreen(&self) -> bool

Returns true if prev_state is one of the fullscreen states and new_state is not.

pub fn is_moved(&self) -> bool

Returns true if this event represents a window move.

pub fn is_resized(&self) -> bool

Returns true if this event represents a window resize.
