This is View-question in view mode; [Up]
Date: Sun 07-Aug-1989 21:12:58 From: Unknown Subject: View question Gang, Does anyone know of a simple way to change the order of display of views and their subviews? I'm trying to develop a class that will implement the "knobbies", dragging and resizing options of the standard Draw application (extended for my own use). As of now, I'm assuming that this new ResizableItem class is a subclass of View, and that it contains a subclass of View as its item to be drawn (note: the Draw app uses subclasses of Object, and implements its own draw and selection operations). However, if I let the standard display operation do the drawing by calling drawSelf::, my new class (which will draw the knobbies) gets drawn first, then overlaid by the subviews that it is supposed to be highlighting. The point of doing all this is to try and use the standard view-subview hierarchy (since it already exists) to do something that the Draw application does now, without having to simulate all of Draw's changing of frame and bounds. Any help on this is GREATLY appreciated, Dave (combs@sumex-aim.stanford.edu) >From: jpd00964@uxa.cso.uiuc.edu

The first subviews added get drawn first, with later ones getting put on top of them. You could pull them out of the list and put them back in again. However, from you posting, if I understand correctly, I think you might find it easier to add the "knobbies" as a subview of you rectangles instead of the other way around. Either that, or include a flag in each rectangle object on if it should have knobbies or not. Then, in its drawSelf:: routine, you could draw the knobs if the flag is set and not draw them if its not. Michael Rutman Softmed >From: johnl@tw-rnd.SanDiego.NCR.COM (John Lindwall)
