Struct WindowCtx 

pub struct WindowCtx(/* private fields */);

Defines the backing data of WINDOW.

Each window owns this data and calls WINDOW.with_context to delegate to it’s child node.

Implementations

impl WindowCtx

pub fn new(id: WindowId, mode: WindowMode) -> Self

New window context.

pub fn set_widget_tree(&mut self, widget_tree: WidgetInfoTree)

Sets the widget tree, must be called after every info update.

Window contexts are partially available in the window new closure, but values like the widget_tree is available on init, so a WidgetInfoTree::wgt must be set as soon as the window and widget ID are available.

pub fn id(&self) -> WindowId

Gets the window ID.

pub fn mode(&self) -> WindowMode

Gets the window mode.

pub fn widget_tree(&self) -> WidgetInfoTree

Gets the window tree.

pub fn with_state<R>( &mut self, f: impl FnOnce(&mut OwnedStateMap<WINDOW>) -> R, ) -> R

Call f with an exclusive lock to the window state.

pub fn share(&mut self) -> Self

Clone a reference to the window context.

This must be used only if the window implementation is split.
