Day 94: Medicated

Sinuses have been acting up these past few days, but now, as the title proclaims, I am medicated and much better. As such, I've gotten some stuff done:

• #110 is done; the mission editor has minibuilders and they're very pretty and almost exactly how I envisioned them long ago when I drew the design.


• #124 was quite a bit more work. The editor for Conditions and Actions doesn't act like any other editor, because you're never working on the base 'Condition' or 'Action' object. Rather, you select a subclass and work on that. Turned out to be pretty easy to have a list box on the left that selected the subclass, and the right is an appropriate editor.
  
  Actually, the 'appropriate editor' part being easy is half-right. The properties dialog, from which this descends, lays out fields (things like 'name', basic text/numeric stuff) without regard to what class it's doing it for. But children (i.e. other serializable objects) vary wildly and the properties dialog doesn't do anything with them, leaving it to subclasses to sort it out.
  
  Thus, I created a helper class to detect which subclass of KuiAction/KuiCondition it was working on, and lay out the children accordingly. This was annoyingly difficult, because I had to refactor all of the layout logic so a non-property dialog could use it, and then somehow shoehorn it back in. It's still a bit of a hack, but it gets the job done, and this is the only place I should need it.
  


• Fixed a bug where scrolling in a list would appear to forget your current selection. Turns out it still remembers the selection behind the scenes, but it didn't bother re-painting it.

Finally, a helpful ruby tip. This:

case(object.class)
when KuiBlarg
  setup_kui_blarg
end

Doesn't work how you might expect (i.e. at all). Instead, do this:

case(object)
when KuiBlarg
  setup_kui_blarg
end
