Expand description
An operation to be performed on some window.
Variants§
Spawn(Id, Settings)
Spawns a new window with some Settings
.
Close(Id)
Close the window and exits the application.
Drag(Id)
Move 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 function is called.
Resize(Id, Size)
Resize the window to the given logical dimensions.
FetchSize(Id, Box<dyn FnOnce(Size) -> T>)
Fetch the current logical dimensions of the window.
FetchMaximized(Id, Box<dyn FnOnce(bool) -> T>)
Fetch if the current window is maximized or not.
§Platform-specific
- iOS / Android / Web: Unsupported.
Maximize(Id, bool)
Set the window to maximized or back
FetchMinimized(Id, Box<dyn FnOnce(Option<bool>) -> T>)
Fetch if the current window is minimized or not.
§Platform-specific
- Wayland: Always
None
. - iOS / Android / Web: Unsupported.
Minimize(Id, bool)
Set the window to minimized or back
Move(Id, Point)
Move the window to the given logical coordinates.
Unsupported on Wayland.
ChangeMode(Id, Mode)
Change the Mode
of the window.
FetchMode(Id, Box<dyn FnOnce(Mode) -> T>)
Fetch the current Mode
of the window.
ToggleMaximize(Id)
Toggle the window to maximized or back
ToggleDecorations(Id)
RequestUserAttention(Id, Option<UserAttention>)
Request 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 UserAttention
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: Unsupported.
- macOS:
None
has no effect. - X11: Requests for user attention must be manually cleared.
- Wayland: Requires
xdg_activation_v1
protocol,None
has no effect.
GainFocus(Id)
Bring the window to the front and sets input focus. Has no effect if the window is already in focus, minimized, or not visible.
This method steals input focus from other applications. Do not use this method unless you are certain that’s what the user wants. Focus stealing can cause an extremely disruptive user experience.
§Platform-specific
- Web / Wayland: Unsupported.
ChangeLevel(Id, Level)
Change the window Level
.
ShowWindowMenu(Id)
Show window menu at cursor position.
§Platform-specific
Android / iOS / macOS / Orbital / Wayland / Web / X11: Unsupported.
FetchId(Id, Box<dyn FnOnce(u64) -> T>)
Fetch the raw identifier unique to the window.
ChangeIcon(Id, Icon)
Change the window Icon
.
On Windows and X11, this is typically the small icon in the top-left corner of the titlebar.
§Platform-specific
-
Web / Wayland / macOS: Unsupported.
-
Windows: 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.
Screenshot(Id, Box<dyn FnOnce(Screenshot) -> T>)
Screenshot the viewport of the window.
