[REBOL] Re: help? dynamic images

Hi Russ,
<< I'd like to dynamically add (append) images to a layout. That I can
do. But then I'd like to selectively REMOVE them from the layout... by
name or other identifier or index. I have achieved removing the LAST one I
added, but have not figured how to create an index or identifier so that I
can selectively remove a PARTICULAR one. >>
I haven't done it by index, but I have done it by face. I.e. the user can
click on a face (an image in your case) and hit Ctrl+Delete. I watch for
keystrokes and if I see Ctrl+Delete in a face, I do this:
remove find face/parent-face/pane face
My code is actually a little more involved because I have multiple "related"
faces that need to be deleted if *any* of them are deleted, but that's the
basic idea.
