void ansicht.BaumAnsicht.paint

(

Graphics

g

)

Invoked by Swing to draw components

Parameters:

g

the Graphics context in which to paint

Reimplemented in ansicht.BalloonBaumAnsicht, ansicht.RadialBaumAnsicht, and ansicht.StandardBaumAnsicht.

void ansicht.BaumAnsicht.zeichneVerbindungen	(	JTree	einBaum,
		Graphics2D	g2D
	)			[protected]

Draws the connections between the leaves as specified in the tree einBaum.

We used open uniform cubic B-Splines to draw the connections.

Parameters:

	einBaum	the tree whose connections are to be drawn
	g2D	the Graphics context in which to paint

void ansicht.BaumAnsicht.zeichneBaum	(	JTree	einBaum,
		Graphics2D	g2D
	)

Draws the tree einBaum. The type of the tree determines the tree layout.

Parameters:

	einBaum	the tree to be drawn
	g2D	the Graphics context in which to paint

Reimplemented in ansicht.BalloonBaumAnsicht, and ansicht.StandardBaumAnsicht.

void ansicht.BaumAnsicht.zeichneEbene	(	Enumeration	einEnum,
		float	distanz,
		Graphics2D	g2D
	)

Iterates recursively through the levels of the tree using depth-first traversal and draws all nodes of the tree.

This method draws the children of all nodes specified in einEnum and calls the method for each of the children.

Parameters:

	einEnum	the Enumeration used to iterate through.
	distanz	represents the distance between the different levels of the radial tree
	g2D	the Graphics context in which to paint

void ansicht.BaumAnsicht.zeichneKinder	(	BaumKnoten	wurzel,
		float	distanz,
		Graphics2D	g2D
	)

Draws the children of the node wurzel.

The method calculates the position and the limits of each node to be drawn. The limits are used to determine the correct position of the node.

Parameters:

	wurzel	represents the parent node whose children are drawn
	distanz	represents the distance between the different levels of the radial tree
	g2D	the Graphics context in which to paint

Reimplemented in ansicht.RadialBaumAnsicht.

void ansicht.BaumAnsicht.zeichnePunkt	(	Point2D.Double	position,
		Graphics2D	g2D
	)

Draws a point at the position specified by position.

The point is actually an ellipse. We use gradient paint to fill the ellipse.

Parameters:

	position	the position of the point to be drawn
	g2D	the Graphics context in which to paint
