Class DesktopEventManagementPolicy

java.lang.Object

ej.mwt.DesktopEventManagementPolicy

All Implemented Interfaces:

ej.microui.util.EventHandler

public class DesktopEventManagementPolicy
extends java.lang.Object
implements ej.microui.util.EventHandler

Dispatches the event received on a desktop to its children.

• Pointer events are grouped in sessions. A session starts when the pointer is pressed, and ends when the pointer is released.

  While no renderable consumes the events, they are sent to the renderable that is under the pointer (see Desktop.panelAt(int, int) and Panel.getWidgetAt(int, int)), then sent to all its parent hierarchy.

  Once a renderable has consumed an event, it will be the only one to receive the next events during the session.

• For other events, the events are sent to the focus owner (see Widget.hasFocus()), then sent to all its parent hierarchy while the event is not consumed.
