- - ### Constructor Detail

    - #### PjPickEvent

          public PjPickEvent()

      Constructor.

  - ### Method Detail

    - #### init

          public void init()

      Initialization.
      Overrides:
        `init` in class `PjProject`

    - #### start

          public void start()

      Method is invoked during loading of a project in JavaView.
      Overrides:
        `start` in class `PjProject`
      See Also:
        `PvViewerIf.start()`, `PjProject.isEnabledAutoFit()`

    - #### update

          public boolean update(java.lang.Object event)

      Update the class whenever a child has changed. Method is usually invoked from the children.
      Specified by:
        `update` in interface `PsUpdateIf`
      Overrides:
        `update` in class `PsObject`
      Parameters:
        `event` - carries a lot of information
      Returns:
        true if event has been handled, otherwise false
      See Also:
        `PsObject.setParent(PsUpdateIf)`, `PsObject.getFather()`, `PsObject.addUpdateListener(PsUpdateIf)`

    - #### pickInitial

          public void pickInitial(PvPickEvent pos)

      Receive an "Initial Pick" event. This is one of the methods required by PvPickListenerIf; it is already implemented by the super class PjProject (without doing anything but fulfilling the interface). Here this method is overwritten to have some reaction on the initial pick event. This method will usually be called by a display in all registered pick listeners, when an initial pick is done. Initial pick events may be invoked by clicking on the geometry with either the display's major mode set to jv.project.PvDisplayIf.MODE_INITIAL_PICK or with "i" key pressed.
      Specified by:
        `pickInitial` in interface `PvPickListenerIf`
      Overrides:
        `pickInitial` in class `PjProject`
      Parameters:
        `pos` - Pick event issued by the display
      See Also:
        `PvPickListenerIf`
