public class Triangle

extends PolyShape

implements Shape

A triangle shape. (Really, just a polygon with 3 vertices.) The main operations are to read the x and y coordinates of the upper-left corner and the center of the bounding rectangle around the triangle (getX(), getY(), getCenterX(), and getCenterY()), to change the position of the upper-left corner (moveBy(...) and moveTo(...)), to rotate the triangle around some point (rotateAround(...)), to read and change the color of the triangle (getColor() and setColor(...)), and add to and remove from a GWindow (addTo(...) and removeFromWindow()). Other operations are mainly for internal use, and should not be called by regular client programs.

Constructor Summary

Triangle()
Create a new blue, filled triangle with default position and size.

Triangle(int x1, int y1, int x2, int y2, int x3, int y3)
Create a new black, unfilled triangle between the given three vertices

Triangle(int x1, int y1, int x2, int y2, int x3, int y3, java.awt.Color c, boolean fill)
Create a new triangle of the given color and filledness between the given three vertices
