Division of Labor

Since there seems to be a fair bit of interest in the success of DWT, here are a few questions in reference to it:

1) How many people are working on this project?

2) Who are they?

3) What is being done?

4) How are we going to organize who does what so that we don't have overlapping development?

5) How are we going to manage new volunteers?

6) What documentation will be prepared for the project?

It would probably be useful and desirable to have some of these questions answered soon.

I'm also thinking that we should have a class heirarchy chart of SWT made so that those involved can know, more or less at a glance, how things fit together. I started my own, but it's not very good, and I'm wondering if it would be better to have it in an html format so that it's easily browsable.

Can we discuss some of these items?

my observation is that, inheritance in separate file only work on the fist one, as soon as i inherite a class from a already inherited one, i get forward reference issue.

Ex:

- Widget > Control > Button
- Widget > Composite > OleClientSite

If in the same file, it look to work. dunno if there is a problem or the guy on the chair is the problem Very Happy

If you can boil it down to a simple example, post it to the NG. Walter can see it and have a go at fixing it.

First, thanks Brad for posting that information. I wasn't sure what was going on with DWT outside my world.

Steve, my experience with the forward referencing was very confusing. What I did try to do was put a bunch of the classes in the same file to see if the forward references went away. Surprisingly they didn't. Circular inheritances and aggregates (in classes in the same file) still caused forward reference issues in the compiler. So the compiler seems to fail with this problem when symbols are referenced before their definition EVEN within the same module. I don't know why this is so, but it seems to be just the tip of the iceberg.

Languages such as Modula-3 are designed so that you don't worry about forward references (at the expense of more compiler complexity). It looks like the D implementation hasn't figured it out yet for classes.

Hopefully, we can get a good simple example together to point out the issue clearly.

Hmmm... looks interesting. Maybe this example is one to ask Walter about. It may relate in some way to the problem.

Wow...32 object files is good! What's your secret? Smile

Did you report it to Walter? Of course, I guess he expects a simplified example of the error, which might be hard to do.
