Disclaimer: I know nothing about any perl Gtk modules!

There isn't such a thing as a "hex number" in Perl. There are strings that are used to represent hex numbers and they can be converted to integers using oct or hex.

Is the following code any help? 

my $hex = "0x3cb37180";
my $dec = oct $hex;

say $dec;                 # 1018392960
say sprintf "0x%X", $dec; # 0x3CB37180

Since you didn't say which module you're using I couldn't check it's documentation to check what $rect->set is expecting

Unless I state otherwise, all my code runs with strict and warnings
