Hi all,
I have a bunch of data files I need to go through and make certain changes to. I thought this would be a good opportunity to learn some perltk and write a gui interface for my editor program. Unfortunately now that I start trying to use it for real, I realise that it is really slow because I wrote it in a stupid way. The particular supidity is that every time I move to a different part of the file to edit, I destroy my mainwindow and make a new one with: 

my $main = MainWindow->new;

[download]

to display the different part of the file. Unfortunately this happens really slowly (the windows have a lot of widgets in but just getting a new mainwindow at all seems to be slow) It really would more more hassle than it is worth to rewrite the way the code fundamentally works. But what I am wondering is, is there any kind of cunning way to, I don't know, keep things in memory or something, so that it isn't so slow to make a new mainwindow?

Cheers,
Ben
