Method Summary

java.awt.Rectangle	getBounds() Describe the rectangular area within the EditorPanel where this Drawable vertex is to be painted.
java.awt.Point	getCentre() Describe where the centre of the Drawable visually appears to a viewer.

java.awt.Point	getConnectionPoint(java.awt.Point other) Calculate the Point where a DrawableArc connecting to this DrawableVertex should be drawn to, no
java.awt.Point	getConnectionPointMovableCentre(java.awt.Point other) A more visually pleasing implementation of getConnectionPoint(java.awt.Point) for use on rectangular Drawables that allows the centre of the object you are connecting with to be treated as only loosely defining where the connection point should be aligned to, such that as the other point moves to the right, so the centre of the drawable moves a little to the right

DrawVertex

public DrawVertex(EditorPanel ep,
                  Positionable p)

Method Detail

getPositionable

public Positionable getPositionable()

Return the Positionable that this Drawable is providing a graphical representation of.

Specified by:

getPositionable in interface Drawable

getConnectsTo

public Positionable[] getConnectsTo()

Specified by:

getConnectsTo in interface Drawable

setText

protected final void setText(java.lang.String s)

Set the text that will be used in this {link @Drawable}, and record its width and height in textBounds.

getBounds

public java.awt.Rectangle getBounds()

Description copied from interface: DrawableVertex

Describe the rectangular area within the EditorPanel where this Drawable vertex is to be painted.

Specified by:

getBounds in interface DrawableVertex

getCentreOffset

public java.awt.Point getCentreOffset()

Implements the Drawable

Specified by:

getCentreOffset in interface DrawableVertex

Returns:

A point that is an offset within getBounds(), where the graphical centre of this Drawable lies

getCentre

public java.awt.Point getCentre()

Describe where the centre of the Drawable visually appears to a viewer.

Specified by:

getCentre in interface DrawableVertex

Returns:

A point that is the absolute coordinate of the , graphical centre of this Drawable.

getConnectionPoint

public java.awt.Point getConnectionPoint(java.awt.Point other)

Description copied from interface: DrawableVertex

Calculate the Point where a DrawableArc connecting to this DrawableVertex should be drawn to, no

Specified by:

getConnectionPoint in interface DrawableVertex

Returns:

Point

getConnectionPointMovableCentre

public java.awt.Point getConnectionPointMovableCentre(java.awt.Point other)

A more visually pleasing implementation of getConnectionPoint(java.awt.Point) for use on rectangular Drawables that allows the centre of the object you are connecting with to be treated as only loosely defining where the connection point should be aligned to, such that as the other point moves to the right, so the centre of the drawable moves a little to the right

paintSymbol

public void paintSymbol(java.awt.Graphics2D g)

paintText

public void paintText(java.awt.Graphics2D g)

paintComponent

public void paintComponent(java.awt.Graphics2D g)

Specified by:

paintComponent in interface Drawable

intersectLine

public static java.awt.Point intersectLine(java.awt.Rectangle bounds,
                                           java.awt.Polygon p,
                                           int x1,
                                           int y1,
                                           int x2,
                                           int y2)

Return the Point where a line intersects a Polygon
