P Save and restore the window state.

If enabled a config entry is created for the window state in CONFIG, and if a config backend is set the window state is persisted on change and restored when the app reopens.

impl Window

pub fn widget_new() -> Self

Start building a new instance.

impl Window

pub fn start_position(&self, position: impl IntoValue<StartPosition>)

c Defines how the window is positioned when it first opens.

impl Window

pub fn start_focused(&self, enabled: impl IntoValue<bool>)

c If the window is steals keyboard focus on open.

By default the operating system decides if the window will receive focus after opening, usually it is focused only if the process that started the window already has focus. Enabling this ensures that focus is moved to the new window, potentially stealing the focus from other apps and disrupting the user.

impl Window

pub fn kiosk(&self, kiosk: impl IntoValue<bool>)

c Lock-in kiosk mode.

In kiosk mode the only window states allowed are fullscreen or fullscreen exclusive, and all subsequent windows opened are child of the kiosk window.

Note that this does not configure the operating system, you still need to setup a kiosk environment. This just stops the app itself from accidentally exiting fullscreen.

impl Window

pub fn allow_transparency(&self, allow: impl IntoValue<bool>)

c If semi-transparent content is see-through, mixing with the operating system pixels behind the window.

Note that to actually see behind the window you must set the clear_color and background_color to a transparent color. The composition is a simple alpha blend, effects like blur do not apply to the pixels behind the window.

impl Window

pub fn render_mode(&self, mode: impl IntoValue<Option<RenderMode>>)

c Render performance mode overwrite for this window, if set to None the WINDOWS.default_render_mode is used.

The view-process will try to match the mode, if it is not available a fallback mode is selected, see RenderMode for more details about each mode and fallbacks.
