The Cocoa Drawing Guide states "Cocoa event objects return y coordinate values that are 1-based instead of 0-based. Thus, a mouse click on the bottom left corner of a window or view would yield the point (0, 1) in Cocoa and not (0, 0). Only y-coordinates are 1-based."
Why are the y-coordianate values of Cocoa event objects 1-based? Do most developers simply subtract 1.0 from the y-coordianate value obtained from an event object to make it 0-based before using the x-y-coordinate values? --Richard _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
