Struct POPUP

pub struct POPUP;

Expand description

Popup service.

Implementations§

pub fn open(&self, popup: impl UiNode) -> ReadOnlyArcVar<PopupState>

Open the popup using the current context config vars.

If the popup node is not a full widget after init it is upgraded to one. Returns a variable that tracks the popup state and ID.

pub fn open_config( &self, popup: impl UiNode, anchor_mode: impl IntoVar<AnchorMode>, context_capture: impl IntoValue<ContextCapture>, ) -> ReadOnlyArcVar<PopupState>

Open the popup using the custom config vars.

If the popup node is not a full widget after init it is upgraded to one. Returns a variable that tracks the popup state and ID.

pub fn close(&self, state: &ReadOnlyArcVar<PopupState>)

Close the popup widget when state is not already closed.

Notifies POPUP_CLOSE_REQUESTED_EVENT and then close if no subscriber stops propagation for it.

pub fn force_close(&self, state: &ReadOnlyArcVar<PopupState>)

Close the popup widget when state is not already closed, without notifying POPUP_CLOSE_REQUESTED_EVENT first.

pub fn close_id(&self, widget_id: WidgetId)

Close the popup widget by known ID.

The widget_id must be the same in the PopupState::Open returned on open.

You can also use the POPUP_CLOSE_CMD scoped on the popup to request or force close.

pub fn force_close_id(&self, widget_id: WidgetId)

Close the popup widget without notifying the request event.

pub fn anchor_id(&self) -> impl Var<WidgetId>

Gets a read-only var that tracks the anchor widget in a layered widget context.
