Method Summary

(package private) static boolean	checkPolygonLength(java.awt.Polygon polygon, java.awt.Component component)
void	createFromShapeRecord(ShapeRecord shapeRecord) Called from subclasses that override this method, this class only sets the shapeID variable
boolean	createNewShapeOnMousePress() Returns true
void	draw(java.awt.Graphics g) Sets the color and draws the black squares aroudn the Drawable
protected Point[]	getBlackSquares() Returns an empty array; This method is overwritten in subclasses
InsertSQL	getInsertSQL(int scoredImageID) Returns a SQL statement to update an existing shape in the database.
UpdateSQL	getUpdateSQL() Returns a SQL statement to insert this shape into the database.
void	handleMouseDragged(java.awt.event.MouseEvent e) Moves the shape depending on difference between last point, if the user has finished drawing it.
void	handleMousePressed(java.awt.event.MouseEvent e) Registers tempX and tempX if moving is allowed
void	handleMouseReleased(java.awt.event.MouseEvent e) Does nothing: unlike most shapes MouseReleased() does not mean the user is done drawing the shape
boolean	isValid() Returns true if the shape is "worth saving".
protected void	move(int xDiff, int yDiff) Moves the shape by adding xDiff and YDiff to it's current x and y, respectively.
boolean	shouldPointActivate(int xPos, int yPos) Returns true if the x and y are close enough to the border of the shape to "Select" the shape
