Struct winit::Window
[−]
[src]
pub struct Window { /* fields omitted */ }
Represents a window.
Example
use winit::{Event, EventsLoop, Window, WindowEvent, ControlFlow}; let mut events_loop = EventsLoop::new(); let window = Window::new(&events_loop).unwrap(); events_loop.run_forever(|event| { match event { Event::WindowEvent { event: WindowEvent::CloseRequested, .. } => { ControlFlow::Break }, _ => ControlFlow::Continue, } });
Methods
impl Window
[src]
pub fn new(events_loop: &EventsLoop) -> Result<Window, CreationError>
[src]
Creates a new Window for platforms where this is appropriate.
This function is equivalent to WindowBuilder::new().build(events_loop)
.
Error should be very rare and only occur in case of permission denied, incompatible system, out of memory, etc.
pub fn set_title(&self, title: &str)
[src]
Modifies the title of the window.
This is a no-op if the window has already been closed.
pub fn show(&self)
[src]
pub fn hide(&self)
[src]
pub fn get_position(&self) -> Option<(i32, i32)>
[src]
Returns the position of the top-left hand corner of the window relative to the top-left hand corner of the desktop.
Note that the top-left hand corner of the desktop is not necessarily the same as the screen. If the user uses a desktop with multiple monitors, the top-left hand corner of the desktop is the top-left hand corner of the monitor at the top-left of the desktop.
The coordinates can be negative if the top-left hand corner of the window is outside of the visible screen region.
Returns None
if the window no longer exists.
pub fn get_inner_position(&self) -> Option<(i32, i32)>
[src]
Returns the position of the top-left hand corner of the window's client area relative to the top-left hand corner of the desktop.
The same conditions that apply to get_position
apply to this method.
pub fn set_position(&self, x: i32, y: i32)
[src]
Modifies the position of the window.
See get_position
for more information about the coordinates.
This is a no-op if the window has already been closed.
pub fn get_inner_size(&self) -> Option<(u32, u32)>
[src]
Returns the size in pixels of the client area of the window.
The client area is the content of the window, excluding the title bar and borders.
These are the dimensions that need to be supplied to glViewport
.
Returns None
if the window no longer exists.
pub fn get_inner_size_points(&self) -> Option<(u32, u32)>
[src]
Returns the size in points of the client area of the window.
The client area is the content of the window, excluding the title bar and borders.
To get the dimensions of the frame buffer when calling glViewport
, multiply with hidpi factor.
Returns None
if the window no longer exists.
DEPRECATED
pub fn get_inner_size_pixels(&self) -> Option<(u32, u32)>
[src]
Returns the size in pixels of the client area of the window.
The client area is the content of the window, excluding the title bar and borders.
These are the dimensions of the frame buffer, and the dimensions that you should use
when you call glViewport
.
Returns None
if the window no longer exists.
DEPRECATED
pub fn get_outer_size(&self) -> Option<(u32, u32)>
[src]
Returns the size in pixels of the window.
These dimensions include title bar and borders. If you don't want these, you should use
use get_inner_size
instead.
Returns None
if the window no longer exists.
pub fn set_inner_size(&self, x: u32, y: u32)
[src]
Modifies the inner size of the window.
See get_inner_size
for more information about the values.
This is a no-op if the window has already been closed.
pub fn set_min_dimensions(&self, dimensions: Option<(u32, u32)>)
[src]
Sets a minimum dimension size for the window.
Width and height are in pixels.
pub fn set_max_dimensions(&self, dimensions: Option<(u32, u32)>)
[src]
Sets a maximum dimension size for the window.
Width and height are in pixels.
pub unsafe fn platform_display(&self) -> *mut c_void
[src]
DEPRECATED. Gets the native platform specific display for this window. This is typically only required when integrating with other libraries that need this information.
pub unsafe fn platform_window(&self) -> *mut c_void
[src]
DEPRECATED. Gets the native platform specific window handle. This is typically only required when integrating with other libraries that need this information.
pub fn set_cursor(&self, cursor: MouseCursor)
[src]
Modifies the mouse cursor of the window. Has no effect on Android.
pub fn hidpi_factor(&self) -> f32
[src]
Returns the ratio between the backing framebuffer resolution and the window size in screen pixels. This is typically one for a normal display and two for a retina display.
pub fn set_cursor_position(&self, x: i32, y: i32) -> Result<(), ()>
[src]
Changes the position of the cursor in window coordinates.
pub fn set_cursor_state(&self, state: CursorState) -> Result<(), String>
[src]
Sets how winit handles the cursor. See the documentation of CursorState
for details.
Has no effect on Android.
pub fn set_maximized(&self, maximized: bool)
[src]
Sets the window to maximized or back
pub fn set_fullscreen(&self, monitor: Option<MonitorId>)
[src]
Sets the window to fullscreen or back
pub fn set_decorations(&self, decorations: bool)
[src]
Turn window decorations on or off.
pub fn set_always_on_top(&self, always_on_top: bool)
[src]
Change whether or not the window will always be on top of other windows.
pub fn set_window_icon(&self, window_icon: Option<Icon>)
[src]
Sets the window icon. On Windows and X11, this is typically the small icon in the top-left corner of the titlebar.
For more usage notes, see WindowBuilder::with_window_icon
.
Platform-specific
This only has an effect on Windows and X11.
pub fn set_ime_spot(&self, x: i32, y: i32)
[src]
Sets location of IME candidate box in client area coordinates relative to the top left.
pub fn get_current_monitor(&self) -> MonitorId
[src]
Returns the monitor on which the window currently resides
pub fn id(&self) -> WindowId
[src]
