You can now click items onto the map, move them with a combination of the mouse and shift key and double click items either in the list or on the map to open a property panel.
I'm currently at work on the property panel. I've decided to just draw a grid like the panel in my Builder app, then move a borderless edit control over the field being edited. I'm pretty sure that's how Builder's TStringGrid implements it.
It is all going fine so far. One thing I can't figure out at the moment is how to intercept keystrokes to an edit control, but I haven't really tried yet. I had a scan of the PSDK docs last night and I can't find any notification messages that edit controls send the parent on a key press. Does anyone reading this know much about this?
If I can't figure it out after a reasonable amount of trying I'll ask on the forums and get twenty answers within about ten seconds I expect. I'm actually finding quite frequently that when the PSDK and MSDN fail me, I type my question into Google and the top three hits in response are all here in the forums on Gamedev anyway.
