public LineTool(DrawingCanvas canvas)

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

Parameters:

canvas - the canvas on which to place lines.

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

mouseDragged

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

Called if the mouse is dragged (the mouse button is down and mouse is moving). If we are constructing a line, move its last locator as indicated.

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 line, move its last locator as indicated. When done, consume the event.

Overrides:

mouseMoved in class AbstractInputEventHandler

Parameters:

e - the event

mouseReleased

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

Called if the mouse is released. If we are constructing a line, and the shift key is down, add another point. Otherwise, we're done constructing this one... get ready for the next one.

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 line. Assumes that pointIndex is a valid point in the current line being edited.

Parameters:

pointIndex - the index of the point to move.

x - the x coordinate.

y - the y coordinate.
