Re: bezier path redraw problems

You asked for it...I'm not sure how elegant the superview-superview business is...

Pete


- (void)drawLineToMovie:(NSEvent *)theEvent
{
//Command Drag Happening, draw path to movie
NSPoint tmpCentre = NSZeroPoint;
NSPoint rectCentre = NSZeroPoint;
tmpCentre = [selectedItem centre];
//create bezier path with colour
NSBezierPath *lineToMovie = [NSBezierPath bezierPath];
[[NSColor blackColor] set];
NSPoint mouseLoc;
mouseLoc = [[[[self superview] superview] superview] convertPoint: [theEvent locationInWindow] fromView:nil];
//create array of points - from selected rect to current mouse pos - with extra point in middle for right angle
rectCentre = [[[[self superview] superview] superview] convertPoint: tmpCentre fromView:self];
[lineToMovie moveToPoint: rectCentre];
[lineToMovie lineToPoint: NSMakePoint(rectCentre.x , mouseLoc.y)];
[lineToMovie lineToPoint: mouseLoc];
[lineToMovie setLineWidth: 20.0];
[lineToMovie stroke];
[[[[self superview] superview] superview] setNeedsDisplayInRect: [lineToMovie bounds]];
}
