exec

public boolean exec(int key,

                    java.lang.Object... params)

Description copied from class: GralUserAction

This method should be override by the users class. In the implementation the user can cast from the widgd given as interface to the known implementation widget type because the GralUserAction is associated to a specific widget.

If this method is not overridden from the GralUserAction super class, it tries to call the deprecated GralUserAction.userActionGui(int, GralWidget, Object...) because that method may be overridden.

Overrides:

exec in class GralUserAction

Parameters:

key - See KeyCode. Any special action is designated with 0.

widgd - The Gral which calls this method in any of its implementation methods. This parameter designates the source of the call with some specific properties in the widget. For example ((GralWidget)widgd).getCmd() can be invoked.

params - Some optional values, depending on special user designation. In most cases no parameter. The user may be test the type of parameter for complex usage.

Returns:

true if execution is succeed. false if the users application can't deal with the actionCode or the widget.
