Struct window::NoWindow

pub struct NoWindow { /* private fields */ }

A window without user interface, often used in server event loops.

This structure holds just enough state to return values that were set. The size can be changed because the event loop does not emit Render events when the width or height is zero.

Implementations

impl NoWindow

pub fn new(settings: &WindowSettings) -> NoWindow

fn set_exit_on_esc(&mut self, _value: bool)

Sets whether to exit when pressing esc.

fn get_automatic_close(&self) -> bool

Gets whether the window will automatically close when attempting to close it.

fn set_automatic_close(&mut self, value: bool)

Sets whether the window will automatically close when attempting to close it. If this is disabled, attempts to close the window can be detected via an Input::Close(..) event, and Window::set_should_close() can be called to actually close the window.

fn set_capture_cursor(&mut self, _value: bool)

Sets whether to capture/grab the cursor.

fn show(&mut self)

Shows the window.

fn hide(&mut self)

Hides the window.

fn get_position(&self) -> Option<Position>

Gets the position of window.

fn set_position<P: Into<Position>>(&mut self, val: P)

Sets the position of window.

fn set_size<S: Into<Size>>(&mut self, val: S)

Sets the window size.

fn title(self, value: String) -> Self

Sets title on window.

fn exit_on_esc(self, value: bool) -> Self

Sets whether to exit when pressing the Esc button.

fn automatic_close(self, value: bool) -> Self

Sets whether the window will automatically close when attempting to close it. If this is disabled, attempts to close the window can be detected via an Input::Close(..) event, and Window::set_should_close() can be called to actually close the window.

fn capture_cursor(self, value: bool) -> Self

Sets whether to capture/grab the cursor.

fn position<P: Into<Position>>(self, val: P) -> Self

Sets the position of window.

impl Debug for NoWindow

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Window for NoWindow

fn set_should_close(&mut self, value: bool)

fn size(&self) -> Size

Gets the size of the window.

fn swap_buffers(&mut self)

fn wait_event(&mut self) -> Event

Wait indefinitely for an input event to be available from the window.

fn wait_event_timeout(&mut self, _timeout: Duration) -> Option<Event>
