Class IlvButtonInteractor

java.lang.Object
  ilog.views.IlvObjectInteractor
      ilog.views.objectinteractor.IlvButtonInteractor

All Implemented Interfaces:

Serializable

public class IlvButtonInteractor
extends IlvObjectInteractor

This object interactor makes a graphic object act like a standard interface button. When this object interactor is installed for a given graphic object, clicking on or activating the graphic object produce an action event. The action listeners of the graphic object receive three different kinds of action event: The ARM action event, when the object is clicked on, the DISARM action event when the mouse button is released, and the ACTIVATE action event when the mouse button is released over the object. The ARM and DISARM action events let you perform a specific graphic operation on the object (changing its color, for example) to indicate that an action is about to be performed. The ACTIVATE action event carries out the action associated with the button. You may code a listener as below:

 graphic.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent event) {
      if (event.getID() == IlvButtonInteractor.ARM) {
        graphic.setBackgound(Color.red);
        graphic.reDraw();
      }
      else if (event.getID() == IlvButtonInteractor.DISARM) {
        graphic.setBackground(Color.gray);
        graphic.reDraw();
      }
      else // ACTIVATE
        performMyAction();
    }
})
