All Implemented Interfaces:

ActivityEvent, Serializable

public class ActivityNameEvent
extends ActivityPropertyEvent

ActivityNameEvent is fired by an IlvActivity both before and after its name is modified. Immediately before its name is modified, an IlvActivity fires an aboutToChange ActivityNameEvent in all listeners registered with the Gantt data model. Listeners can modify or constrain the proposed name by invoking setNewName(). Alternatively, a listener can veto the proposed change by invoking veto().

After its name is modified, an IlvActivity will fire a changed ActivityNameEvent in all listeners registered with the Gantt data model. Listeners can access the old and new values of the activity's name, but cannot modify them via the event mechanism.

Constructor Detail

ActivityNameEvent

public ActivityNameEvent(IlvActivity activity,
                         String oldName,
                         String newName,
                         boolean aboutToChangeEvent)

Constructs a new ActivityNameEvent generated by the specified activity and with the specified old and new name values.

Parameters:

activity - the activity where the event originated

newName - the activity's new name

aboutToChangeEvent - true if this is an activityNameAboutToChange event or false if this is an activityNameChanged event.

Method Detail

getOldName

public String getOldName()

Returns the activity's old name. If this is a activityNameAboutToChange event, then this will be the same as the activity's current name since the change has not actually occurred yet. If this is a activityNameChanged event, this will be the activity's name prior to the current modification being reported.

Returns:

The String representing the activity's old name.

getNewName

public String getNewName()

Returns the activity's new name. If this is a activityNameAboutToChange event, then this is will be the activity's proposed value. If this is a activityNameChanged event, this will be the activity's new name which is being reported.

Returns:

The String representing the activity's new name.

setNewName

public void setNewName(String name)

Sets the activity's proposed new name. This method only has meaning if this is a activityNameAboutToChange event. By using this method, a listener can constrain changes to the activity's name.

Parameters:

name - the activity's name
