Enum Target

Source

pub enum Target {
    Global,
    Window(WindowId),
    Widget(WidgetId),
    Auto,
}

Expand description

The target of a Command.

Variants§

§

Global

The target is the top-level application.

The Command will be delivered to all open windows, and all widgets in each window. Delivery will stop if the event is handled.

§

Window(WindowId)

The target is a specific window.

The Command will be delivered to all widgets in that window. Delivery will stop if the event is handled.

The target is a specific widget.

§

Auto

The target will be determined automatically.

How this behaves depends on the context used to submit the command. If the command is submitted within a Widget method, then it will be sent to the host window for that widget. If it is from outside the application, via ExtEventSink, or from the root AppDelegate then it will be sent to Target::Global .
