Haitham:
Please visit the following webpage for details of file/picture chooser
widgets written in Rev:
http://www.howsoft.com/runrev/stacks.htm
These widgets do, of course, include HD trees.
The standalone widgets exist for Windows XP/2000 and Ubuntu Linux. In
view of the fact that I do not possess sufficient machines for testing
versions for MAC and other flavours of Linux, I intend to release the
source stacks so that other developers can make the adaptions for these
platforms. I shall be releasing the stacks within the next few days.
What this means for you personally, apart from using the widgets as they
stand, is that you can adapt the HD treeviews as you want.
I don't know whether or not other programmers would find it easy or
difficult to produce HD treeviews in Rev. The fact is, that so far they
don't seem to have done it very much. Certainly, for me, the development
of these stacks was non-trivial to say the least. (On the other hand, it
was my first real attempt at producing an application in Rev. In actual
fact, I did it in VB6 first, and then "translated" it into Transcript.)
I believe that one other programmer has produced a treeview widget
fairly recently (but NOT for the HD), which you can add to or subtract
from. If you look back on the Use-Rev Lists, you are sure to find it

Bob Warren
