Implementations

impl<P> State<P>

where P: Program, <P as Program>::Theme: DefaultStyle,

pub fn new(application: &P, window_id: Id, window: &dyn Window) -> State<P>

Creates a new State for the provided Program’s window.

pub fn viewport(&self) -> &Viewport

Returns the current Viewport of the State.

pub fn viewport_version(&self) -> u64

Returns the version of the Viewport of the State.

The version is incremented every time the Viewport changes.

pub fn physical_size(&self) -> Size<u32>

Returns the physical Size of the Viewport of the State.

pub fn logical_size(&self) -> Size

Returns the logical Size of the Viewport of the State.

pub fn scale_factor(&self) -> f64

Returns the current scale factor of the Viewport of the State.

pub fn set_logical_cursor_pos(&mut self, pos: LogicalPosition<f64>)

pub fn cursor(&self) -> Cursor

Returns the current cursor position of the State.

pub fn modifiers(&self) -> ModifiersState

Returns the current keyboard modifiers of the State.

pub fn theme(&self) -> &<P as Program>::Theme

Returns the current theme of the State.

pub fn background_color(&self) -> Color

Returns the current background Color of the State.

pub fn text_color(&self) -> Color

Returns the current text Color of the State.

pub fn icon_color(&self) -> Color

Returns the current icon Color of the State.

pub fn update( &mut self, window: &dyn Window, event: &WindowEvent, _debug: &mut Debug, )

Processes the provided window event and updates the State accordingly.

pub fn synchronize( &mut self, application: &P, window_id: Id, window: &dyn Window, )

Synchronizes the State with its Program and its respective window.

Normally, a Program should be synchronized with its State and window after calling State::update.
