jpicedt.graphic.model
Class Drawing  

java.lang.Object
  jpicedt.graphic.model.Drawing

All Implemented Interfaces:

javax.swing.undo.StateEditable

---

public class Drawing

extends java.lang.Object

implements javax.swing.undo.StateEditable

An extensible array used to store Elements

This is the model (aka javax.swing.text.Document) to be plugged into an existing PECanvas.

Objects are stored in ascending order according to their z-value, i.e. from back to front.

Since:

PicEdt 1.3 ; modified 1.3.2-beta6

Field Detail

root

protected Drawing.RootElement root

the root-element of the drawing

---

listenerList

protected javax.swing.event.EventListenerList listenerList

list of listener's (e.g. DrawingListener's) that get notified events from this model

---

notParsedCommands

protected java.lang.String notParsedCommands

a string containing commands read from file but not parsed

---

boundingBox

protected java.awt.geom.Rectangle2D boundingBox

bounding box used when formatting to text ; null means that it'll be computed automatically

viewFactory

private jpicedt.graphic.view.ViewFactory viewFactory

Constructor Detail

Drawing

public Drawing()

Construct a new empty Drawing

Since:

jPicEdt 1.3

---

Drawing

public Drawing(java.util.Collection c)

Construct a new Drawing from the given Collection, which is supposed to contain Element's. Children are cloned beforehands.

Since:

jPicEdt 1.3

---

Drawing

public Drawing(BranchElement e)

construct a new Drawing whose content is initialized from the content of the given BranchElement. Children are cloned beforehands, so it's perfectly safe to use this constructor if one doesn't want to modify the initial content of the given BranchElement.

Since:

jPicEdt 1.3

---

Drawing

public Drawing(Drawing dr)

cloning constructor

Since:

jPicEdt 1.3.2

Method Detail

clone

public java.lang.Object clone()

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }

Remove the given graphic object from this Drawing, overriden so as to update selection if this element was selected.

---

addElement

public void addElement(Element element)

Add the given element to this Drawing

---

replaceElement

public void replaceElement(int index,
                           Element element)

Replace the element at the given index with the given graphic element

---

elements

public java.util.Iterator elements()

---

getElement

public Element getElement(int i)

---

getBoundingBox

public java.awt.geom.Rectangle2D getBoundingBox()

---

setBoundingBox

public void setBoundingBox(java.awt.geom.Rectangle2D bb)

set bounding box manually ; set to null to switch back to automatic behaviour

getRootView

public jpicedt.graphic.view.View getRootView()

---

setViewTree

public void setViewTree(jpicedt.graphic.view.ViewFactory f)

set the view tree that renders this drawing to screen, starting from the root-element. The root-view produced by the factory (to be associated with the root-element) must know how to find its container (normally a PECanvas), otherwise calls to repaint, etc... will fail.

---

addDrawingListener

public void addDrawingListener(jpicedt.graphic.event.DrawingListener l)

adds a DrawingListener to the Drawing

---

removeDrawingListener

public void removeDrawingListener(jpicedt.graphic.event.DrawingListener l)

removes a DrawingListener from the Drawing

---

fireChangedUpdate

protected void fireChangedUpdate(Element[] changed,
                                 jpicedt.graphic.event.DrawingEvent.EventType type)

Notify all listeners that have registered interest for notification on this event type.

---

fireChangedUpdate

protected void fireChangedUpdate(Element changed,
                                 jpicedt.graphic.event.DrawingEvent.EventType type)

Notify all listeners that have registered interest for notification on this event type.

---

storeState

public void storeState(java.util.Hashtable map)

Store a clone of RootElement in the given Hashtable, with key = "state"

Specified by:

Specified by:

restoreState in interface javax.swing.undo.StateEditable

---

toString

public java.lang.String toString()

Returns a String representing the drawing for debugging use only.

---

setNotparsedCommands

public void setNotparsedCommands(java.lang.String str)

---

getNotparsedCommands

public java.lang.String getNotparsedCommands()

---

getCustomizer

public Drawing.Customizer getCustomizer()
