Canal locks in scenario editor

[odd-sock]

Hey All

I'd like to enhance the scenario editor so that it supports the ability to create canal locks. I'm a full time programmer, with a reasonabe understanding of c/c++. However, this will be my first contribution to OpenTTD, and the mass of code is a bit overwhelming.

Could some point me in the right direction on how to implement this patch?

Specifically:

* Is there any known technical limitation why this would not be possible?
* Which code files would be of interest to me?
* How do I add an extra button to a window (and make them function)?
* Are there any other caveats that I should be aware of?
* Assuming I am successful in making the change, how do I then release the change?

Thanks,

Patrick

I can only answer the first question - there is no technical impediment to allowing canal locks to be built in the scenario editor. It's simply an interface thing.

Well i'd firstly check out dock_gui.c, seems a likely place to put that kind of thing.

To release it, you can post a source patch, or the full source, plus a Windows exe always goes down well with those who don't know how to compile.

Ya, I'd quite like this, don't really know why it's missing in the first place really
