Class AbstractMouseTransformFactory

java.lang.Object

jpicedt.graphic.toolkit.AbstractMouseTransformFactory

All Implemented Interfaces:

MouseTransformFactory

Direct Known Subclasses:

EditElementMouseTransformFactory, EditPointMouseTransformFactory

public abstract class AbstractMouseTransformFactory
extends java.lang.Object
implements MouseTransformFactory

Provide a skeletal implementation of the MouseTransformFactory interface. This include some generic MouseTransform's which may be easily extended by concrete subclassers, like SelectAreaMouseTransform.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
protected class	AbstractMouseTransformFactory.HelpMessageMouseTransform This mouse transform does nothing, it is just a convenience to post a HelpMessage (regarding what the user COULD do) when no other mouse-transform makes sense with the current mouse-event.
protected class	AbstractMouseTransformFactory.InvalidMouseTransform This mouse transform does nothing, it simply returns an invalid cursor, and can be used by MouseTransform factories to notify the user of an invalid UI action.
protected class	AbstractMouseTransformFactory.SelectAreaTransform a mouse-transform dedicated to select objects (Element's, control-point's,...) inside a rectangle dragged by the user.

Method Summary

Modifier and Type	Method and Description
void	flush() called when the associated SelectionTool is being deactivated in the hosting EditorKit.
EditorKit	getEditorKit() Return the hosting EditorKit for mouse-tools which work with this factory.
void	init() called when the associated SelectionTool is being activated in the hosting EditorKit.
void	paint(java.awt.Graphics2D g, java.awt.geom.Rectangle2D allocation, double scale) Allows the MouseTransformFactory to do specific graphic rendering when it's installed in a hosting SelectionTool.

Constructor Detail

AbstractMouseTransformFactory

public AbstractMouseTransformFactory(EditorKit kit)

Parameters:

kit - the hosting editor-kit

Method Detail

getEditorKit

public final EditorKit getEditorKit()

Return the hosting EditorKit for mouse-tools which work with this factory. This may be used to work with the selection-handler and use hitTest() methods.

paint

public void paint(java.awt.Graphics2D g,
                  java.awt.geom.Rectangle2D allocation,
                  double scale)

Allows the MouseTransformFactory to do specific graphic rendering when it's installed in a hosting SelectionTool. This default implementation does nothing.

Specified by:

paint in interface MouseTransformFactory

Since:

jpicedt 1.4

init

public void init()

called when the associated SelectionTool is being activated in the hosting EditorKit. Initialization work required before any mouse-event occurs should be done here. Other initialization work may be carried out in the MouseTransform's themselves.

This implementation does nothing.

Specified by:

init in interface MouseTransformFactory

flush

public void flush()

called when the associated SelectionTool is being deactivated in the hosting EditorKit. This provides a way for the factory to do some final clean-up, e.g. local buffers, graphic context,...

This implementation does nothing.

Specified by:

flush in interface MouseTransformFactory
