Struct WindowScope 

pub struct WindowScope { /* private fields */ }

A Window and its builder.

Implementations

impl WindowScope

pub fn title(self, title: impl Into<String>) -> Self

What the window calls itself.

pub fn size(self, width: f32, height: f32) -> Self

The size the window opens at, in dp. A later change resizes it.

pub fn min_size(self, width: f32, height: f32) -> Self

The smallest size the user can make it, in dp.

pub fn resizable(self, resizable: bool) -> Self

pub fn report_size(self, report: bool) -> Self

Asks to be told every time the window’s width or height, rounded to whole dp, changes. Without it the size is reported only when its class or the safe area changes. Turn it on only for a window that lays out by its exact size: each whole-dp change while the user drags an edge costs one call into the Host.

pub fn chrome(self, chrome: Chrome) -> Self

Who draws the caption.

pub fn title_bar(self, title_bar: TitleBar) -> Self

Which of the two title bars the window has.

pub fn icon(self, asset_id: u32) -> Self

The window’s icon, as the id of a registered asset. Without one it wears the application’s.

pub fn position(self, x: f32, y: f32) -> Self

Where the window sits, in screen dp from the top left of the main screen. Changing it moves the window; the position the user chose is not given back. Without it the platform places the window.

pub fn restore_key(self, key: impl Into<String>) -> Self

The application’s stable name for the window, which matches a window the system brings back to the node that describes it.

pub fn zoom_level(self, level: i8) -> Self

The window’s own application zoom level, kept inside its range.

pub fn drag_from_pointer(self, drag: DragFromPointer) -> Self

Opens the window under a pointer that is held down and follows it until it is let go. Read when the window opens and not again.

pub fn theme(self, theme: Theme) -> Self

A theme for this window over the application’s.

pub fn on_focus_changed(self, handler: impl FnMut(bool) + 'static) -> Self

The window became the key window or stopped being it.

pub fn on_moved(self, handler: impl FnMut(WindowFrame) + 'static) -> Self

The window’s outer frame moved or changed size.

pub fn on_drag(self, handler: impl FnMut(WindowDragEvent) + 'static) -> Self

The window is being dragged out of a tab, and how that ended.

pub fn on_unavailable(self, handler: impl FnMut() + 'static) -> Self

The platform could not open this window. Tell the user, or put the tab back.

pub fn on_closed(self, handler: impl FnMut() + 'static) -> Self

The system closed the window without asking. Stop composing it.

pub fn content(self, content: impl FnOnce())

Composes this window with content as its children.

Trait Implementations

impl Drop for WindowScope

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
