Tree view
Hi, Does anyone know how to build a "tree-view" ? (somethig similar to the left part of the "explorer" of windows) or does anyone know where to find documentation about it? thanks, regards, Miro Casanova

Sorry if this is a duplicate, I think I screwed up the previous reply... * Miro Casanova wrote: > Does anyone know how to build a "tree-view" ?

Sorry for the .tar.gz file, it has .bmp images in it. I have no idea if this is anything like the right way to do this, I just wrote it as a hack. I've only tested it on Windows but it kind of should work on Linux/Unix I think (my Linux box is turned off at the moment and we don't have a Solaris license...). There's no sysdcl, it should be enough to compile & load directory-browser.lisp. I think this only works in 4.2, but I seem to remember using it in 4.1.20, so maybe? --tim
It is documented in the CAPI Reference Manual (and does work under 4.1)
In the simplest case it works just like below. You can also attach the
selection-callback, etc to provide functionality.
CL-USER 11 > (setf *roots* '((1 (2) (3) (4)) (5 (6) (7) (8))))
((1 (2) (3) (4)) (5 (6) (7) (8)))
CL-USER 12 > (capi:contain
(make-instance 'capi:tree-view
:roots *roots*
:print-function
(lambda (node)
(princ-to-string (first node)))
:children-function 'rest))

Is there something more specific you are asking? Are you concerned on how to build the
data structures that represent the tree?
