Instance Method

lineToPoint:

Appends a straight line to the receiver’s path

Declaration

- (void)lineToPoint:(NSPoint)point;

Parameters

aPoint

The destination point of the line segment, specified in the current coordinate system.

Discussion

This method creates a straight line segment starting at the current point and ending at the point specified by the aPoint parameter. The current point is the last point in the receiver’s most recently added segment.

You must set the path's current point (using the moveToPoint: method or through the creation of a preceding line or curve segment) before you invoke this method. If the path is empty, this method raises an NSGenericException exception.
