Also see embedding xterm into a Tk app. If you are determined to use embeded Canvases, you could use this technique, to hide show them. Tk is somwhat limited and you need to cover the createWindow with another properly colored rectangle.

Tk::Zinc can actually hide or show the window. See the second example in Re: Window with background image and transparent listbox . You could put a second Zinc canvas in there, instead of an xterm.

[perldigious]: A question since I'm ignorant of what's normal for database management... Do admins change column names a lot in databases?
[perldigious]: On occasion my scripts break, because they will do something that seems laregly pointless to me... like in this case, changing a column name from "ABC Category" to "ABC Category Override".
[perldigious]: Being the ignorant one, my initial reaction to that is, "that's sort of a dick move, a lot of people like me expect column names like that to stay the same, why the hell would you change them like that for seemingly no good reason?"
[perldigious]: Or is my irritation/ frustration well founded?
[Corion]: perldigious: That seems to be more the export and likely it's the recipients of that export that like the titles changes
[Corion]: ... "changed"
[Corion]: I usually expect fixed header names, but am sometimes lenient in the order of columns. But changing the report titles often sounds to me as if you are not the sole consument of the export ;)
