Constructor Detail

ConnectingLineTool

public ConnectingLineTool(DrawingCanvas canvas)

Constructs and initializes a new instance of a tool to create connecting 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 LineTool

Parameters:

x - the x coordinate

y - the y coordinate

mousePressed

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

Called if the mouse goes down. When creating the new line, see if the first point is on top of another figure, and connect it if possible.

Overrides:

mousePressed in class ShapeTool

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, finalize the latest point by seeing if it is one that could connect to an underlying figure and, if so connect it. We're done constructing this one unless the shift key is down in which case we add another point and keep going. Otherwise, get ready to construct the next one.

Overrides:

mouseReleased in class LineTool

Parameters:

e - the event
