dd is in fact an instance of class Window in module gtk.Window.
DMD got it right so far.

but why would the method void move(int,int) be called
instead of the method void foo() ????????????????

I posted a similar problem about a year and a half ago just to be ignored.

so help me: how do I post this in the bugs group?

Ant

PS what happens is that the window I have on the screen is
actually moved to somewhere else,
it actually disappears from the screen.

There is not enough information in this post to get any help but guesses.

Have you got some source code we can look at? I see from the DUI forum that
you can't reduce the size of the source code to narrow it down. Well, maybe
someone else can if you don't know how to - or are you saying that if you
delete *anything* from the source, the problem goes away? If not, just keep
removing things until the problem does go away. That will give you a clue
or two about what might be causing it.  (Take a full back up first, of
course).

It's calling method dd.foo() from inside method move(), I believe.

Need a few more details: OS, DUIT version, DMD version ; how can we 
reproduce this? do we just download the version from svn?  What steps do 
we take to compile and discover the problem?  Can you step us through 
what leads to the error?

get

ad see the README* for compilation and more details...

I have no more ideas...

Thanks, Ant.  I downloaded it this morning, but have been busy at work 
and such.  I'll try to test it when I get the chance.

Thank you, Derek and John.
I'll review this and try to post more details.

Seems I found the problem with this.

moving the import declarations to the module level (from the class body)
seems to do the trick.

I originally had all imports a the module level but that created another
problem (don't remember what).

I'll move all import to module level and try to see if the original problem
can be solved.

Thank you all for your help, specially Lars Ivar and h3r3tic!

PS I asked Walter (about 2 year ago) if imports on the class body
should be used or were just a side effect - he completely ignore the question.

There have been several discussions concerning that practice since then, Ant
(perhaps you missed them? :) ) Many of these discussions were somewhat heated
because the name lookup rules seemed counter-intuitive.   If I recall correctly,
Mango and the original DWT port ran into this issue too.

Walter responded something to the effect that imports were not designed to be
placed in class bodies, so we were "on our own" if we decided to put them there.

Glad you were able to get this fixed, though!  Thanks also to Lars and Tom for
helping out.
