in reply to Controlling resize of Tk::Panedwindow
For reference, the thread author opened an issue at the Perl/Tk GitHub repository: https://github.com/eserte/perl-tk/issues/75
While incorporating Tcl/Tk 8.5+ or Ttk into Perl/Tk continues to seem unlikely, I think backporting -stretch could be possible; will comment further on the GitHub issue.
