Subject: Bug in getOpenFile/getSaveFile

text/plain 1019b
I think it's a bug, that getOpenFile needs at least two elements in the array for -filetypes. #!/usr/bin/perl use Tk; my $mw = MainWindow->new(); my $filetypes = [['pdf','.pdf']]; $mw->getOpenFile(-filetypes => $filetypes); MainLoop; produces the following error message: bad file type "ARRAY(0x1a5b338)", should be "typeName {extension ?extensions ... ?} ?{macType ?macTypes ...?}?" at C:/usr/lib/Tk.pm line 320. But the following code works fine: #!/usr/bin/perl use Tk; my $mw = MainWindow->new(); my $filetypes = [['pdf','.pdf'],['pdf','.pdf']]; $mw->getOpenFile(-filetypes => $filetypes); MainLoop; My system: OS: Microsoft Windows XP [Version 5.1.2600] Perl: This is perl, v5.8.6 built for MSWin32-x86-multi-thread (with 3 registered patches, see perl -V for more detail) Copyright 1987-2004, Larry Wall Binary build 811 provided by ActiveState Corp. http://www.ActiveState.com ActiveState is a division of Sophos.

This seems to be Windows-only. The code works as expected on FreeBSD with perl5.8.0+Tk800.024 and perl5.8.7+Tk804.027.

There's an additional/related bug with file types *In Windows* If you specify two arguments to file types it will work the first time, however on one of the successive opens it will simply crash/exit, I've found that if I add an empty array ref [] at the end of the file types list, it will both prevent the above error, as well as this one. my $filetypes = [ ['Text Files', ['.txt', '.prt']], ['All Files', '*', ] ]; $mw->getOpenFile(-filetypes => $filetypes); ## Works first try, but on a successive try crashes my $filetypes = [ ['Text Files', ['.txt', '.prt']], ['All Files', '*', ], [] ]; $mw->getOpenFile(-filetypes => $filetypes); ## No Crash
