Squirrel

 If not, can they be emulated?

No they are not supported,

In my project we simply use global tables like this:

GUIEvent = {
 Clicked = 1,
 Resized = 2,
 MouseMove = 3,
 ...
}

Makes sense and that is what I ended up doing, works just as well so you are right, why bother with another construct when it serves no advantage?

Good job again for your design, Squirrel as a language is just wonderful. I just wish the tools were a bit more refined.

fagiano:

GUIEvent = {
 Clicked = 1,
 Resized = 2,
 MouseMove = 3,
 ...
}

This doesn't seem to work. You say that you are using a global table, but this doesn't seem to follow the global format. As far as I can tell, it should be something more like this:

GUIEvent <- {
 Clicked = 1,
 Resized = 2,
 MouseMove = 3,
 ...
}

This seems to work fine for the individual script that it's declared in, but any attempts to use this value from another script or from within C++ do not work. The docs fall short of useful examples here IMO. How should this be accessed from each? Is this considered to be part of the root table after it is executed?

This DOES NOT work:

const SquirrelObject rt = SquirrelVM::GetRootTable();
int value = rt.GetInt("GUIEvent.Resized");

'value' will be set to 0 every time. What am I doing wrong?

You skipped one step, try that instead :

const SquirrelObject rt = SquirrelVM::GetRootTable();
SquirrelObject key = rt.GetValue(_T("GUIEvent"));
int Value = key.GetInt(_T("Resized"));
