Enum druid::Target

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

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.

Widget(WidgetId)

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 .

Trait Implementations

impl Clone for Target

fn clone(&self) -> Target

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Target

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<WindowId> for Target

fn from(id: WindowId) -> Target

Converts to this type from the input type.

impl PartialEq<Target> for Target

fn eq(&self, other: &Target) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
