pub struct Canvas { /* private fields */ }
Expand description
An abstract structure representing a window for native applications, and a canvas for web applications.
Implementations
sourceimpl Canvas
impl Canvas
sourcepub fn open(
title: &str,
hide: bool,
width: u32,
height: u32,
canvas_setup: Option<CanvasSetup>,
out_events: Sender<WindowEvent>
) -> Self
pub fn open(
title: &str,
hide: bool,
width: u32,
height: u32,
canvas_setup: Option<CanvasSetup>,
out_events: Sender<WindowEvent>
) -> Self
Open a new window, and initialize the OpenGL/WebGL context.
sourcepub fn render_loop(data: impl RenderLoopClosure)
pub fn render_loop(data: impl RenderLoopClosure)
Run the platform-specific render loop.
sourcepub fn poll_events(&mut self)
pub fn poll_events(&mut self)
Poll all events tha occurred since the last call to this method.
sourcepub fn swap_buffers(&mut self)
pub fn swap_buffers(&mut self)
If double-buffering is supported, swap the buffers.
sourcepub fn cursor_pos(&self) -> Option<(f64, f64)>
pub fn cursor_pos(&self) -> Option<(f64, f64)>
The current position of the cursor, if known.
This position may not be known if, e.g., the cursor has not been moved since the window was open.
sourcepub fn scale_factor(&self) -> f64
pub fn scale_factor(&self) -> f64
The scale factor.
sourcepub fn set_icon(
&mut self,
icon: impl GenericImage<Pixel = impl Pixel<Subpixel = u8>>
)
pub fn set_icon(
&mut self,
icon: impl GenericImage<Pixel = impl Pixel<Subpixel = u8>>
)
Set the window icon. See Window::set_icon
for details.
sourcepub fn set_cursor_grab(&self, grab: bool)
pub fn set_cursor_grab(&self, grab: bool)
Set the cursor grabbing behaviour.
sourcepub fn set_cursor_position(&self, x: f64, y: f64)
pub fn set_cursor_position(&self, x: f64, y: f64)
Set the cursor position.
sourcepub fn hide_cursor(&self, hide: bool)
pub fn hide_cursor(&self, hide: bool)
Toggle the cursor visibility.
The state of a mouse button.
