Instance Method

drawArrow:highlight:

Draws the scroll button indicated by arrow, which is either NSScrollerIncrementArrow (the down or right scroll button) or NSScrollerDecrementArrow (up or left).

Declaration

- (void)drawArrow:(NSScrollerArrow)whichArrow highlight:(BOOL)flag;

Discussion

If flag is YES, the button is drawn highlighted; otherwise it’s drawn normally. You should never need to invoke this method directly, but may wish to override it to customize the appearance of scroll buttons.
