Constructor Detail

AnySidedPolygonTool

public AnySidedPolygonTool(DrawingCanvas canvas)

Constructs and initializes a new instance of a tool to create polygons on a DrawingCanvas

Parameters:

canvas - the canvas on which to place PolygonFigures.

Method Detail

basicNewFigure

protected Figure basicNewFigure(int x,
                                int y)

Create and answer a new Figure.

Overrides:

basicNewFigure in class ConstructionTool

Parameters:

x - the x coordinate

y - the y coordinate

Returns:

a newly created Figure

defaultNumberOfSides

protected int defaultNumberOfSides()

Answer the default/initial number of sides.

Returns:

an integer representing the default/initial number of sides.

mouseDoubleClicked

protected void mouseDoubleClicked(java.awt.event.MouseEvent e)

Called when the mouse is double-clicked.

Overrides:

mouseDoubleClicked in class AbstractInputEventHandler

Parameters:

e - the MouseEvent to handle.

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent e)

Called if the mouse is dragged (moved with the mouse button down). If we are constructing a polygon, move its last point as indicated, and consume the event.

Overrides:

mouseDragged in class ConstructionTool

Parameters:

e - the event

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent e)

Called if the mouse moves (when the mouse button is up). If we are constructing a polygon, move its last point as indicated.

Overrides:

mouseMoved in class AbstractInputEventHandler

Parameters:

e - the event

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent e)

Called if the mouse goes up.

Overrides:

mouseReleased in class ShapeTool

Parameters:

e - the event

movePoint

protected void movePoint(int pointIndex,
                         int x,
                         int y)

Move the identified point of the polygon. Assumes that pointIndex is a valid point in the current polygon being edited

Parameters:

pointIndex - the index of the point to move.

x - the x coordinate.

y - the y coordinate.
