This is Base-coords-to-view-coords in view mode; [Up]
Date: Sun 05-May-1991 18:48:54 From: scottsm@brahms.udel.edu (Scott M Stark) Subject: Base coords to view coords I would like to convert a point returned in an NXEvent from its base coordinates to a view coordinate system. There are several routines to covert coords between views and between the screen and base coordinate systems, but I have not found one to covert a base coordinate to a view's coordinate system. I would appreciate any suggestions on how to do this without having to trapse through the view heirarchy. Scott

Calling the following method with aView == nil will convert the point from the base coordinate system of the window to the view's coordinate system. - convertPoint:(NXPoint *)aPoint fromView:aView; Ali, Ali_Ozer@NeXT.com
