:) The first sentence of the original post says "cross-platform".

Though I am a gnome user 99% of my time on computer:)

Now I can better explain what kind of user interface I wish to achieve,
here is a mock-up:

Thanks for all of your feedback you gave.

You need a Visualization System: tkpath or tkzinc!
The tk canvas cannot handle the "shadow"-effect from your example.

tkzinc: building three groups representing the two listbox elements and
another group for details. Construct the second listbox element as a
contour. tkzinc has difficulties with embedded controls under OSX and
?windows?, such as the visible
scrollbar inside the second listbox element. The background pattern is a
"-tile" element from a conventional image. You will have to use Images
for "Business Categories" and "City Club Business" or overlay
them with a semi-transparent text to create the shadow.


tkpath: Is identical to tkzinc, except: there are no
contours, clipping and without tkzinc specific issues. There is no
-tile feature, you have to directly construct the background pattern.
With gstripes you would simply design a conventional GUI -- using
tk labels, messages, scrollbar, the grid geometry manager and such,
then you would defined an interactive contour for the connection between
the first and the second listbox element. The listbox elements are some
trouble: In theory it should be possible to mirror hugelist as a single
group
into your visualization, although clipping would be a problem
--I've thought about this, but did not do any work
in this direction... It requires to translate the coordinates and to draw
into a gstripes canvas instead of the hugelist canvas...

The standard canvas can do all this. You have to manage the shadow yourself.
See
http://wiki.tcl.tk/15549 (Shadow Photo) and
http://wiki.tcl.tk/15611 (Photo Gallery)

The headings must be a picture because it would be too difficult to shadow
the text.

For the left part use normal canvas commands
.c create rectangle ...
.c create text .... -tag [list row1]
you can than get the bounding box of the text row1, add a few pixel on the
top, left and bottom and draw the grey rectangle below the text but above
the blue rectangle.

For the middle part place a frame in the canvas and use normal grid geometry
manager to add a listbox and a normal scrollbar.

For the right part use normal canvas commands:
..c create text ... -width 100 for word wrapping
for the table below again use the bounding box of the texts to move the
pieces to the correct position.

No the canvas cannot handle the shadow effect.
It is possible to fake a gradient by using layered lines, with an
uniform coloured background, but not with a structured background.

am are you seriously suggesting to fake a shadow gradient with images
--Not even the shadow image works with the structured background?

.... which also means that you have to use fixed-size fonts in the rest of
the given design --forget it and use tkpath or tkzinc!

.... the major workload is to reimplement
the listbox interaction for the first listbox element in your example.

Yes, will suffice for the given task...
.... place a tkpath path element behind the frame and include the
selection to the left in the path description (a gstripes contour).
--tkzinc curve would be slightly easier, though.

This way you will loose any resize-ability; any resize operation will
destroy the design! It's necessary to embed
the middle frame into the tk canvas window with this approach
--don't use the grid geometry manager.

lines and rectangles ain't anti-aliased with tk canvas under X11.
