Hi there,

before I subscribed to this list, I already posted this email (see forwarded 
message, please give me respond...). The mailing-list deamon sent me an 
automatic mail that told me, that my mail...
> Is being held until the list moderator can review it for approval.
Seems that there ist no moderator or he is on holydays.

Maybe you should think about rewriting this text. I was waiting for quite a 
while...

Now please have a look at the forwarded mail. I am dying for some feedback.

Thanks a lot & regards
  Jörg Hohwiller

Hi there,

first of all I want to say thank you to you guyz who develop(ed) SWT.
I am a newbe to it, but I am impressed so far.

For my open-source project, I am currently planning the UI design. Now I am 
thinking about supporting Swing (because it comes with jdk
an people can run it direct) and SWT because it is fast (and has the ability
to be build natively with gcj). 

Now my current idea is to write a wrapper against both Swing and SWT.
But as far as I can see, there are quite a lot of differences between the 
both. My aim is not to support any feature and philosophy of both, but more
to have a simple API to create some windows with menu bars, buttons, and all 
the usual widgets etc. Maybe restricted to one flexible layout manager,...
I do not aim to support trees inside tables and stuff like that in the first 
release :)

I tried a first hack which seems to be promising enoguh, that I can make it.
It seems that just a little memory overhead is caused, but other permormance
loss seems to be ignorable since the most interaction is going directly to the
user and just some events have to be wrapped what causes little overhead.
But the benefit would be quite a lot... (at least for me)

Now I am intereseted, if I am the first one with this aim. 

Next, I hope you would find a little time to give me some suggestions like
- -should I build the SWT implementation on top of jface to support MVC?
- -do you see any big problems in something I might not see right now?
- -should I add something like readAndDispatch in the API (that does nothing
 for Swing) or maybe try to run a separate thread for that (and run into
 the same fuzzy trouble that is caused by Swings Threads).
- -In Swing the widgets are beans and can be build top-down as well as down-top,
 while SWT seems only to support top-down approach cause you have to give the
 parent ancestor in the constructor. Is this right and SWT widgets can not be
 build before the parent is known?
- -I know Swing much better than SWT so far: Is there a "compatibe" layout for
 the GridBagLayout in SWT or will it be very hard to simulate a common layout?

Well I would really appreciate getting your oppinion - even
"your idea is stupid, dont waste your time!" is better than noting!

Thanx a lot there and take care...
Regards
  Jörg
