Tk Library Source Code

Hi,

I was stumbling over an unusual behavior of the hierarchical methods. The attached script will deliver the following output:

Tcl version: 8.4.18
snit version 1.3.1
[::.gf is foo] := This is gFoo 1!
[::.gf isFoo] := This is gFoo 2!
[::.gf is bar] := "::.gf is bar" is not defined
[::.gf isBar] := This is gBar 2!

Tcl version: 8.5.2
snit version 2.2.1
[::.gf is foo] := This is gFoo 1!
[::.gf isFoo] := This is gFoo 2!
[::.gf is bar] := unknown subcommand "bar": must be foo
[::.gf isBar] := This is gBar 2!

The method "isBar" of type gBar is correctly delegated and available to an object .gf of type gFoo, while the method "is bar" is not.

Is this a bug, or did I miss the respective chapter in the docs?

kind regards

The handling of hierarchical methods changed slightly between Snit 1.x and Snit 2.x, which explains why the error messages differ.  In each case, though, to delegate hierarchical methods you need to do something like this:

    delegate method {is *} to foo
