Class PjModel

java.lang.Object
  jv.object.PsObject
      jv.project.PjProject
          vgp.tutor.model.PjModel

All Implemented Interfaces:

java.awt.event.ActionListener, java.lang.Cloneable, java.util.EventListener, PsTimeListenerIf, PsUpdateIf, PvPickListenerIf, java.io.Serializable

public class PjModel

extends PjProject

implements java.awt.event.ActionListener

Tutorial on usage of importing models from file. Three methods to load a geometry from file are presented:

1. The first loading takes place inside the start method of the project where a geometry from a given file is loaded, without any user interaction. Of course, the code may be inserted into any other method than the start() method. This is a batch version.
2. The second loading may be invoked by opening the control panel of JavaView and import a model from the menu

   File -> Import -> ...

   This adds the loaded geometry to this project, and this project overwrites the methods addGeometry() and selectGeometry() to show how the project might react on newly loaded geometries. Here just a message is printed.
3. The third loading may be invoked by including a separate panel of the project PjImportModel into the info panel of this project. In this case the import project should exist as instance, and this project should be its ActionListener to be able to receive events invoked by the import project when its info panel has received user interaction.

public PjModel()

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

start

public void start()

Start method is invoke when project is selected in the viewer. Here the loading of geometry from file is demonstrated as a batch version using another instance of PjImportModel.

Overrides:

start in class PjProject

PvViewerIf.start(), PjProject.isEnabledAutoFit()

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent event)

Specified by:

actionPerformed in interface java.awt.event.ActionListener

addGeometry

public boolean addGeometry(PgGeometryIf geom)

Overwrite method of superclass to be able to react when new geometry is loaded from file by menu import. This method is invoked when the import menu is pressed.

Overrides:

addGeometry in class PjProject

Parameters:

geom - geometry to be added to this project and the current display.

Returns:

false if geometry was null or already registered in project.

selectGeometry

public void selectGeometry(PgGeometryIf geom)

Overwrite method of superclass to be able to react when new geometry is loaded from file by menu import. This method is invoked when the imported geometry is accepted.

Specified by:

selectGeometry in interface PvPickListenerIf

Overrides:

selectGeometry in class PjProject

removeGeometry

public void removeGeometry(PgGeometryIf geom)

Overwrite method of superclass to be able to react when new geometry is loaded from file by menu import. This method is invoked when the imported geometry is cancelled.

Overrides:

removeGeometry in class PjProject
