Enum Members

None = 0_u32

Events are not delivered.

Capture = 1_u32

Events are delivered in the capture phase. The capture phase happens before the bubble phase, runs from the toplevel down to the event widget. This option should only be used on containers that might possibly handle events before their children do.

Bubble = 2_u32

Events are delivered in the bubble phase. The bubble phase happens after the capture phase, and before the default handlers are run. This phase runs from the event widget, up to the toplevel.

Target = 3_u32

Events are delivered in the default widget event handlers, note that widget implementations must chain up on button, motion, touch and grab broken handlers for controllers in this phase to be run.
