Hiding and Showing part of the Tk GUI

Ace128 has asked for the wisdom of the Perl Monks concerning the following question:

Hey Monks,

Before I go to the question, I must say that this place really rocks! So many knowledgable people! Little different "forum" layout, but it works fine.

Question:
Ok, say I made this nice GUI in Tk, where I have created several Tk::Frame's (Tk::LabFrame) to seperate the GUI in different sections. Now, I wanna be able of hiding/showing these frames how I choose (along with the stuff on the frames)! Ideas how to do this? Destroy destroys... I want something like $frame->hide(), and $frame->show(); and natrually, the whole GUI is resized...

Ideas? :)

Thanks,
Ace

Hi! You could use packForget(): `use Tk; my $top = new MainWindow; my $frame = $top->Frame(); $frame->Label(-text=>"Can you see me?")->pack(); $top->Button(-text=>"Hide",-command=>sub{$frame->packForget()})->pack( +); $top->Button(-text=>"Show",-command=>sub{$frame->pack()})->pack(); $frame->pack(); MainLoop();` [download] packForget() removes the widget from the packing order. If you repack it later, it appears at the end of the packing order. You can get the pack configuration with @conf = $frame->packInfo(). The same is possible with grid. Regards, mawe	[reply] [d/l]

Lovely! Works like a charm! This is why I love Tk so much! :) So damn neat, and easy to do otherwise seemable tricky things.	[reply]

Wow, now that is smart :) (why didnt I just think of that?) No.. Gotta try that... Update: Um, doesnt seem to work... $frame->geometry("=0x0+0+0");... damn.. would be neat else... wrong # args: should be "winfo geometry window" at C:\Perl\site\lib/Tk/Submethod.pm	[reply]
