All Implemented Interfaces:

KeyListener, EventListener, PEMouseInputListener

Enclosing class:

DrawToolFactory

protected class DrawToolFactory.AbstractCurveDrawTool
extends MouseTool

a MouseTool suited for drawing any element inheriting from AbstractCurve. Because of slight differences that appear in the drawing sequence, this class currently specializes on PicMultiCurve, PicPsCurve and PicSmoothPolygon. This should be improved in the near future by providing a common interface [SR:pending].

The drawing sequence is as follows:

• OPEN curve : mpress add 0,1,2,3→drag 1→move 3→mpress add 4,5,6→drag 4→move 6→…
• CLOSED curve : mpress add 0,1,2→drag 1→mrel add 3,4,5→move 3→mpress→drag 4→mrel add 6,7,8→move and is terminated by a right-button click.

void	mouseMoved(PEMouseEvent e) set cursor for canvas, then call mouseDragged
void	mousePressed(PEMouseEvent e) A popup-trigger mouse event (e.g. a right click on Unix/Windows): switches back to SELECT_MODE if the iterator is completed or terminates the drawing process.
void	mouseReleased(PEMouseEvent e) CLOSED curve only : add a new point by splitting last segment
void	paint(Graphics2D g, Rectangle2D allocation, double scale) This method is called by the hosting EditorKit : this implementation paints the current element's highlighter.

Constructor Detail

DrawToolFactory.AbstractCurveDrawTool

public DrawToolFactory.AbstractCurveDrawTool(AbstractCurve prototype)

Parameters:

prototype - Prototype which will be cloned, then added to the drawing.

Method Detail

mousePressed

public void mousePressed(PEMouseEvent e)

A popup-trigger mouse event (e.g. a right click on Unix/Windows):

• switches back to SELECT_MODE if the iterator is completed
• or terminates the drawing process.

A left-button SINGLE click either:

• (re)start the task iterator if completed;
• or add a new point;

Specified by:

mousePressed in interface PEMouseInputListener

Overrides:

mousePressed in class MouseTool

mouseReleased

public void mouseReleased(PEMouseEvent e)

CLOSED curve only : add a new point by splitting last segment

Specified by:

mouseReleased in interface PEMouseInputListener

Overrides:

mouseReleased in class MouseTool

mouseDragged

public void mouseDragged(PEMouseEvent e)

set the current point

Specified by:

mouseDragged in interface PEMouseInputListener

Overrides:

mouseDragged in class MouseTool

mouseMoved

public void mouseMoved(PEMouseEvent e)

set cursor for canvas, then call mouseDragged

Specified by:

mouseMoved in interface PEMouseInputListener

Overrides:

mouseMoved in class MouseTool

init

public void init()

called when this tool is being activated in the hosting editor kit

Overrides:

init in class MouseTool

flush

public void flush()

called when this tool is being replaced by another mouse-tool in the hosting editor kit ; this is mainly for mousetools using more than one sequence, for it gives them a chance to clean themselves up for the next time

Overrides:

flush in class MouseTool

paint

public void paint(Graphics2D g,
                  Rectangle2D allocation,
                  double scale)

This method is called by the hosting EditorKit : this implementation paints the current element's highlighter.

Overrides:

paint in class MouseTool
