Description David Kaspar 2007-11-19 09:26:45 UTC

It would be good to have
Scene.pick(Point sceneLocation):List<Widget>
method which returns a list of widget that lays at specified scene location.
The method above is inspecting all Widgets on scene based on their boundaries.

There may be a faster implemetation with method:
Scene.pick(Point sceneLocation,ScenePickTask task):boolean
method which returns a boolean state. ScenePickTask interface is having a method which is invoked for each picked widget:
widgetPicked(Widget widget, Point localLocation):ConnectorState
The method should return ConnectorState.ACCEPT, ConnectorState.REJECT or ConnectorState.REJECT_AND_STOP which similar
meaning as it is used in ConnectProvider interface.

I was thinking why limit this method to the scene.  Why not add the method to the Widget class.  That way you can start the search from any widget.

Comment 2 David Kaspar 2007-11-22 07:47:33 UTC

I totally agree. There is not be any obstacle for having it on Widget.
