[wingide-users] requested features survey
Mon, 21 Jan 2002 03:18:05 -0500

The debugging stuff is interesting, but out of my league. ;) Changing
inline would be cool, but it boggles my mind so I'll move on.

Honestly? Something a bit simpler? I could really go for tool tips
that just remind you of what the function arguments are. :)

On the topic of GUI prototyping, I say just go for a Delphi/Glade
type of gizmo. What's important to me is that it takes very little
time to get things up and running -- like in Delphi you can just
double-click on a widget and be editing its events -- Glade is a
little on the complex side if you ask me.

Also, I would prefer to just use PyGTK directly. Last time I used
wxWindows and wxPython, it didn't seem to work reliably all the time
and frankly, the more libraries and wrappers of libraries between
my program and the user, the more resources it'll take.

I'd go for simple.

2 cents.
