public class IlvGroupInteractor
extends IlvObjectInteractor

The class IlvGroupInteractor is a subclass of IlvObjectInteractor that can be used to define user interactions on a graphic element of a group.

This interactor handles all mouse and keyboard events sent to a graphic object. If the graphic object is contained in a group, the interactor sets a number of properties on this group.

You can attach behavior objects to the group to handle these properties and program how the group will react to user interactions.

The properties set on the group by the interactor are the following:

• For mouse events:
  • eventType - the event type.
  • eventModifiers - the event modifiers.
  • eventElement - the name of the graphic element which received the event.
  • eventX - the X coordinate of the event.
  • eventY - the Y coordinate of the event.
  • eventClickCount - the click count.
• For key events:
  • eventType - the event type.
  • eventModifiers - the event modifiers.
  • eventElement - the name of the graphic element which received the event.
  • eventKeyText - a string representing the event key code.

For example, you can define a prototype containing a rectangle and set a IlvGroupInteractor to that rectangle. You can then define a trigger behavior which sets the target property x to eventX. When you move the mouse over the rectangle, the whole prototype will follow the horizontal position of the mouse.
