Re: A question to the APL vendors on Windows GUIs ...

Which APL interpreter are you using?

I am not aware of the issues you raise. As far as I know, APL uses
standard Windows controls via some mechanism to enable APL syntax.
Therefore, I'd expect all controls to look the same whether hosted by
APL or not. As far as I can tell, they do.

However, because of the custom bridge, some controls/behaviours are
not available e.g the autosizing features of controls in .Net GUIs,
for instance.

Is it possible that it is your APL GUI design that is the culprit? APL
does not have a GUI designer to speak of, certainly not one that comes
close to even the VB6.0 designer, let alone the much better VS2005
one.

If you still hold your conviction, you can do your presentation tier
in (exclusively) Java (or whatever else) and use APL for your buiness
tier. You will need to use something like COM for allowing the two
tiers to communicate. As far as I know, COM and Java present
nightmares of unimaginable complexity ...
