sourcepub fn scale_factor(&self) -> f64
pub fn scale_factor(&self) -> f64
Returns the scale factor that can be used to map logical pixels to physical pixels, and vice versa.
See the dpi
module for more information.
Note that this value can change depending on user action (for example if the window is
moved to another screen); as such, tracking WindowEvent::ScaleFactorChanged
events is
the most robust way to track the DPI you need to use to draw.
Platform-specific
- X11: This respects Xft.dpi, and can be overridden using the
WINIT_X11_SCALE_FACTOR
environment variable. - Android: Always returns 1.0.
- iOS: Can only be called on the main thread. Returns the underlying
UIView
’scontentScaleFactor
.
sourcepub fn inner_position(&self) -> Result<PhysicalPosition<i32>, NotSupportedError>
pub fn inner_position(&self) -> Result<PhysicalPosition<i32>, NotSupportedError>
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 outer_position
apply to this method.
Platform-specific
- iOS: Can only be called on the main thread. Returns the top left coordinates of the window’s safe area in the screen space coordinate system.
- Web: Returns the top-left coordinates relative to the viewport. Note: this returns the
same value as
outer_position
. - Android / Wayland: Always returns
NotSupportedError
.
sourcepub fn outer_position(&self) -> Result<PhysicalPosition<i32>, NotSupportedError>
pub fn outer_position(&self) -> Result<PhysicalPosition<i32>, NotSupportedError>
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.
Platform-specific
- iOS: Can only be called on the main thread. Returns the top left coordinates of the window in the screen space coordinate system.
- Web: Returns the top-left coordinates relative to the viewport.
- Android / Wayland: Always returns
NotSupportedError
.
sourcepub fn set_outer_position<P: Into<Position>>(&self, position: P)
pub fn set_outer_position<P: Into<Position>>(&self, position: P)
Modifies the position of the window.
See outer_position
for more information about the coordinates. This automatically un-maximizes the
window if it’s maximized.
Platform-specific
- iOS: Can only be called on the main thread. Sets the top left coordinates of the window in the screen space coordinate system.
- Web: Sets the top-left coordinates relative to the viewport.
- Android / Wayland: Unsupported.
sourcepub fn inner_size(&self) -> PhysicalSize<u32>
pub fn inner_size(&self) -> PhysicalSize<u32>
Returns the physical size of the window’s client area.
The client area is the content of the window, excluding the title bar and borders.
Platform-specific
- iOS: Can only be called on the main thread. Returns the
PhysicalSize
of the window’s safe area in screen space coordinates. - Web: Returns the size of the canvas element.
sourcepub fn set_inner_size<S: Into<Size>>(&self, size: S)
pub fn set_inner_size<S: Into<Size>>(&self, size: S)
Modifies the inner size of the window.
See inner_size
for more information about the values. This automatically un-maximizes the
window if it’s maximized.
Platform-specific
- iOS / Android: Unsupported.
- Web: Sets the size of the canvas element.
sourcepub fn outer_size(&self) -> PhysicalSize<u32>
pub fn outer_size(&self) -> PhysicalSize<u32>
Returns the physical size of the entire window.
These dimensions include the title bar and borders. If you don’t want that (and you usually don’t),
use inner_size
instead.
Platform-specific
- iOS: Can only be called on the main thread. Returns the
PhysicalSize
of the window in screen space coordinates. - Web: Returns the size of the canvas element. Note: this returns the same value as
inner_size
.
sourcepub fn set_min_inner_size<S: Into<Size>>(&self, min_size: Option<S>)
pub fn set_min_inner_size<S: Into<Size>>(&self, min_size: Option<S>)
sourcepub fn set_max_inner_size<S: Into<Size>>(&self, max_size: Option<S>)
pub fn set_max_inner_size<S: Into<Size>>(&self, max_size: Option<S>)
sourcepub fn set_visible(&self, visible: bool)
pub fn set_visible(&self, visible: bool)
Modifies the window’s visibility.
If false
, this will hide the window. If true
, this will show the window.
Platform-specific
- Android / Wayland / Web: Unsupported.
- iOS: Can only be called on the main thread.
sourcepub fn set_resizable(&self, resizable: bool)
pub fn set_resizable(&self, resizable: bool)
Sets whether the window is resizable or not.
Note that making the window unresizable doesn’t exempt you from handling Resized
, as that event can still be
triggered by DPI scaling, entering fullscreen mode, etc.
Platform-specific
This only has an effect on desktop platforms.
Due to a bug in XFCE, this has no effect on Xfwm.
Platform-specific
- iOS / Android / Web: Unsupported.
sourcepub fn set_minimized(&self, minimized: bool)
pub fn set_minimized(&self, minimized: bool)
Sets the window to minimized or back
Platform-specific
- iOS / Android / Web: Unsupported.
- Wayland: Un-minimize is unsupported.
sourcepub fn set_maximized(&self, maximized: bool)
pub fn set_maximized(&self, maximized: bool)
sourcepub fn is_maximized(&self) -> bool
pub fn is_maximized(&self) -> bool
Gets the window’s current maximized state.
Platform-specific
- Wayland / X11: Not implemented.
- iOS / Android / Web: Unsupported.
sourcepub fn set_fullscreen(&self, fullscreen: Option<Fullscreen>)
pub fn set_fullscreen(&self, fullscreen: Option<Fullscreen>)
Sets the window to fullscreen or back.
Platform-specific
-
macOS:
Fullscreen::Exclusive
provides true exclusive mode with a video mode change. Caveat! macOS doesn’t provide task switching (or spaces!) while in exclusive fullscreen mode. This mode should be used when a video mode change is desired, but for a better user experience, borderless fullscreen might be preferred.Fullscreen::Borderless
provides a borderless fullscreen window on a separate space. This is the idiomatic way for fullscreen games to work on macOS. SeeWindowExtMacOs::set_simple_fullscreen
if separate spaces are not preferred.The dock and the menu bar are always disabled in fullscreen mode.
-
iOS: Can only be called on the main thread.
-
Wayland: Does not support exclusive fullscreen mode and will no-op a request.
-
Windows: Screen saver is disabled in fullscreen mode.
-
Android: Unsupported.
sourcepub fn fullscreen(&self) -> Option<Fullscreen>
pub fn fullscreen(&self) -> Option<Fullscreen>
Gets the window’s current fullscreen state.
Platform-specific
- iOS: Can only be called on the main thread.
- Android: Will always return
None
. - Wayland: Can return
Borderless(None)
when there are no monitors.
sourcepub fn set_decorations(&self, decorations: bool)
pub fn set_decorations(&self, decorations: bool)
sourcepub fn set_always_on_top(&self, always_on_top: bool)
pub fn set_always_on_top(&self, always_on_top: bool)
Change whether or not the window will always be on top of other windows.
Platform-specific
- iOS / Android / Web / Wayland: Unsupported.
sourcepub fn set_window_icon(&self, window_icon: Option<Icon>)
pub fn set_window_icon(&self, window_icon: Option<Icon>)
Sets the window icon. On Windows and X11, this is typically the small icon in the top-left corner of the titlebar.
Platform-specific
- iOS / Android / Web / Wayland / macOS: Unsupported.
On Windows, this sets ICON_SMALL
. The base size for a window icon is 16x16, but it’s
recommended to account for screen scaling and pick a multiple of that, i.e. 32x32.
X11 has no universal guidelines for icon sizes, so you’re at the whims of the WM. That said, it’s usually in the same ballpark as on Windows.
sourcepub fn set_ime_position<P: Into<Position>>(&self, position: P)
pub fn set_ime_position<P: Into<Position>>(&self, position: P)
Sets location of IME candidate box in client area coordinates relative to the top left.
Platform-specific
- iOS / Android / Web: Unsupported.
sourcepub fn request_user_attention(&self, request_type: Option<UserAttentionType>)
pub fn request_user_attention(&self, request_type: Option<UserAttentionType>)
Requests user attention to the window, this has no effect if the application
is already focused. How requesting for user attention manifests is platform dependent,
see UserAttentionType
for details.
Providing None
will unset the request for user attention. Unsetting the request for
user attention might not be done automatically by the WM when the window receives input.
Platform-specific
- iOS / Android / Web / Wayland: Unsupported.
- macOS:
None
has no effect. - X11: Requests for user attention must be manually cleared.
sourcepub fn set_cursor_icon(&self, cursor: CursorIcon)
pub fn set_cursor_icon(&self, cursor: CursorIcon)
sourcepub fn set_cursor_position<P: Into<Position>>(
&self,
position: P
) -> Result<(), ExternalError>
pub fn set_cursor_position<P: Into<Position>>(
&self,
position: P
) -> Result<(), ExternalError>
Changes the position of the cursor in window coordinates.
Platform-specific
- iOS / Android / Web / Wayland: Always returns an
ExternalError::NotSupported
.
sourcepub fn set_cursor_grab(&self, grab: bool) -> Result<(), ExternalError>
pub fn set_cursor_grab(&self, grab: bool) -> Result<(), ExternalError>
Grabs the cursor, preventing it from leaving the window.
There’s no guarantee that the cursor will be hidden. You should hide it by yourself if you want so.
Platform-specific
- macOS: This locks the cursor in a fixed location, which looks visually awkward.
- iOS / Android / Web: Always returns an
ExternalError::NotSupported
.
sourcepub fn set_cursor_visible(&self, visible: bool)
pub fn set_cursor_visible(&self, visible: bool)
Modifies the cursor’s visibility.
If false
, this will hide the cursor. If true
, this will show the cursor.
Platform-specific
- Windows: The cursor is only hidden within the confines of the window.
- X11: The cursor is only hidden within the confines of the window.
- Wayland: The cursor is only hidden within the confines of the window.
- macOS: The cursor is hidden as long as the window has input focus, even if the cursor is outside of the window.
- iOS / Android: Unsupported.
sourcepub fn drag_window(&self) -> Result<(), ExternalError>
pub fn drag_window(&self) -> Result<(), ExternalError>
Moves the window with the left mouse button until the button is released.
There’s no guarantee that this will work unless the left mouse button was pressed immediately before this fn is called.
Platform-specific
- X11: Un-grabs the cursor.
- Wayland: Requires the cursor to be inside the window to be dragged.
- macOS: May prevent the button release event to be triggered.
- iOS / Android / Web: Always returns an
ExternalError::NotSupported
.
