UMG Events

A guide explaines how to use UMG Events.

This page details the methods you can use to call and bind Events in UMG.

Bindable Events

Bindable Events are a way for UMG to mimic the behavior currently used by Slate which needs a single handler to tell it if the Event was handled. You can bind a function in your Widget Blueprint to the event from the Details panel under the Events section (shown below indicated by the yellow arrows).

Indicated above by the yellow box, some Widgets supplement Events through the handling of Interaction. For the example above, in addition to the OnClicked Event for a Button Widget, you are able to specify the handling of click events through setting the Click Method or Touch Method. You can also specify through the IsFocusable option if a button should only be mouse-clickable and never keyboard focusable.

Multicast Events

Multicast Events are the standard way Events are handled in Blueprints.

To use a Multicast Event:

  1. click the Widget in the My Blueprint tab (1).

  2. Scroll down to the Events section in the Details panel, then click the + button for the Event you want to use (2).

  3. The Event appears in the Blueprint graph, where you can connect other nodes to it (3).
