Interface PgGeometryIf

All Superinterfaces:

java.lang.Cloneable, PsUpdateIf

All Known Implementing Classes:

PgGeometry

public interface PgGeometryIf

extends PsUpdateIf, java.lang.Cloneable

This interface must be implemented by all geometries to allow registration and rendering in a display of JavaView. Displays call the method paint(PvGeometryIf) of a registered geometry where the geometry should pass its data to the display. paint() is the most important method of this interface.

An implementation of the interface must assure that whenever a geometry has changed such that an update of the display is required, the update method of the display is called with the geometry as argument.

         disp.update(geom)
 

Then display automatically calls the method geom.paint(PvGeometryIf) to request data from geometry. Each display in JavaView implements the interface PvDisplayIf to be able to handle geometries implementing the interface PgGeometryIf.

The interface PgGeometryIf is implemented by PgGeometry. By subclassing from PgGeometry the user only needs to override a few methods.

The class_name for info/control/material panel and methodMenu must follow special rules namely:

         "name of main class"+"_CP"
         "name of main class"+"_IP"
         "name of main class"+"_MP"
         "name of main class"+"_Menu"

                     boolean aState)

Set drawing flags of this geometry from within the display. Method used be overwritten by subclasses to catch specific states. Currently, this method is not intended for public use.

Subclasses should overwrite this method and call super for unhandled keys.

Parameters:

aKey - flag to be set, choose among PvGeometryIf.SHOW_...

aState - enable or disable state

paint

public void paint(PvGeometryIf dc)

Major rendering method fills an internal container class supplied by the display. Method is invoked by displays in which this instance is registered. Whenever the display receives an update event of this geometry instance, then the display calls the paint method. Therefore, it is essential to follow the following strategy to ensure update of the display container whenever the geometry has changed:

		PgGeometryIf geom;       // An arbitrary geometry class
		disp.addGeometry(geom);  // Register geometry in a JavaView display
		geom.computeSomething(); // Compute or modify geometry, e.g. surface coordinates etc.
		disp.update(geom);       // After changing geometry invoke update of display.
	

The call disp.update(geom) invokes the method geom.paint(dc) to fill the container instance dc which is then rendered inside the display.

Use methods supplied in jv.project.PvGeometryIf to fill a container class. All data is duplicated allowing rendering and interaction while the geometry data in the current class may already be modified, e.g. by numerical processes.

Note: Whenever a geometry is registered in a project jv.project.PjProject then the project automatically registers the geometry in associated displays, and it is sufficient to send an update message to the project with the geometry as argument.

Note: Display properties such as auto-rotation, camera choices etc. are made by calling methods of a display directly, see jv.project.PvDisplayIf.

clone

public java.lang.Object clone()
