jpicedt.graphic.view
Class AbstractView  

java.lang.Object
  jpicedt.graphic.view.AbstractView

All Implemented Interfaces:

View

Direct Known Subclasses:

DefaultViewFactory.CompositeView, DefaultViewFactory.LeafElementView

---

public abstract class AbstractView

extends java.lang.Object

implements View

Abstract implementation that provide some basic common behaviours for View's.

---

Field Summary
protected  java.awt.geom.Rectangle2D	bounds           the bounds rectangle used for clipping (as returned by getBounds) ; this should be updated by changedUpdate.
protected  jpicedt.graphic.model.Element	element           the graphic element that this View renders

 

Fields inherited from interface jpicedt.graphic.view.View

BARBELL_SIZE, CLICK_DISTANCE

 

Constructor Summary

AbstractView(jpicedt.graphic.model.Element element)           construct a new View for the given Element

 

Method Summary
java.awt.geom.Rectangle2D	getBounds()
jpicedt.graphic.PECanvas	getContainer()           Fetches the container hosting the view.
jpicedt.graphic.model.Drawing	getDrawing()           Fetches the model associated with the view.
jpicedt.graphic.model.Element	getElement()
java.awt.Graphics	getGraphics()           Fetch a Graphics for rendering from the hosting container (if not null).
View	getParentView()           Returns the parent of the view, as given by the tree-structure the associated graphic element belongs to.
ViewFactory	getViewFactory()           Fetches the ViewFactory implementation that is feeding the view hierarchy.
HitInfo	hitTest(jpicedt.graphic.event.PEMouseEvent e, boolean isHighlightVisible)           Current implementation returns a HitInfo.Point if highlighter is visible and a click occured on an end-point ; return null otherwise.
void	paint(java.awt.Graphics2D g, java.awt.geom.Rectangle2D a)           This implementation does nothing.
void	paintHighlighter(java.awt.Graphics2D g, java.awt.geom.Rectangle2D allocation, double scale)           Render the Highlighter to the given graphic context. Current implementation paints end-points using the highlighter color if the given allocation intersects the bounds of this view.
void	repaint(java.awt.geom.Rectangle2D clip)           ask the hosting container (if it's non-null) to repaint itself
void	setElement(jpicedt.graphic.model.Element e)           set the element the View is responsible for rendering

Field Detail

element

protected jpicedt.graphic.model.Element element

the graphic element that this View renders

---

bounds

protected java.awt.geom.Rectangle2D bounds

the bounds rectangle used for clipping (as returned by getBounds) ; this should be updated by changedUpdate.

Constructor Detail

AbstractView

public AbstractView(jpicedt.graphic.model.Element element)

construct a new View for the given Element

Method Detail

getElement

public jpicedt.graphic.model.Element getElement()

Specified by:

getElement in interface View

---

setElement

public void setElement(jpicedt.graphic.model.Element e)

set the element the View is responsible for rendering

Specified by:

setElement in interface View

---

getParentView

public View getParentView()

Returns the parent of the view, as given by the tree-structure the associated graphic element belongs to.

Specified by:

getParentView in interface View

---

getContainer

public jpicedt.graphic.PECanvas getContainer()

Fetches the container hosting the view. This is useful for things like scheduling a repaint, finding out the host components font, etc. The default implementation of this is to forward the query to the parent view, if any... (that means that for this method to return non-null, the element attached to this view must have a parent, and this parent, a view, etc...)

Specified by:

getContainer in interface View

---

getViewFactory

public ViewFactory getViewFactory()

Fetches the ViewFactory implementation that is feeding the view hierarchy.

Specified by:

getViewFactory in interface View

---

getGraphics

public java.awt.Graphics getGraphics()

Fetch a Graphics for rendering from the hosting container (if not null). This can be used to determine font characteristics, and will be different for a print view than a component view.

Specified by:

getGraphics in interface View

Since:

1.3

---

getDrawing

public jpicedt.graphic.model.Drawing getDrawing()

Fetches the model associated with the view.

Specified by:

getDrawing in interface View

---

repaint

public void repaint(java.awt.geom.Rectangle2D clip)

ask the hosting container (if it's non-null) to repaint itself

Specified by:

repaint in interface View

---

paint

public void paint(java.awt.Graphics2D g,
                  java.awt.geom.Rectangle2D a)

This implementation does nothing.

Specified by:

paint in interface View

---

paintHighlighter

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

Render the Highlighter to the given graphic context.
Current implementation paints end-points using the highlighter color if the given allocation intersects the bounds of this view.

Specified by:

paintHighlighter in interface View

Since:

jPicEdt 1.3.2

---

getBounds

public java.awt.geom.Rectangle2D getBounds()

Specified by:

getBounds in interface View

Since:

jPicEdt 1.3.2

---

hitTest

public HitInfo hitTest(jpicedt.graphic.event.PEMouseEvent e,
                       boolean isHighlightVisible)

Current implementation returns a HitInfo.Point if highlighter is visible and a click occured on an end-point ; return null otherwise.

Specified by:

hitTest in interface View

Since:

jPicEdt 1.3.2
