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
