Tryst::UI::OptionError
Inherits Tryst::UI::ValidationError < Exception < Reference < Object
Raised in place of a raw TclError: unknown option "-textt" - the
widget identified the way it was built (ui.button(:save), not a Tk
path), the bad option spelled the DSL's own way (textt:, not
-textt), a did-you-mean suggestion, and a sample of what IS valid -
all drawn from a live configure dump rather than a hand-maintained
list that could drift from what Tk itself actually accepts.
