perl/Tk: how do you hide a button, then redisplay it.

P: 3
Hi,

I'm new to Tk. I have 'Mastering Perl/Tk'. I want to 'place' a button, but not display it until after another button is pressed. I assumed that I could create the button, place it, placeForget it and then later in a button callback subroutine just do $mybutton -> place( ); but this doesn't work. Couldn't find any reference in the book to a placeRemember method. Did find MapWindow and UnmapWindow. Is that what I should be using?

It is unfortunate, but most of us here don't have experience with Perl/TK. I would suggest maybe looking into the Tk::Widget module on CPAN. If you don't get any further assistance, then I would suggest posting your question at perlmonks.org. I wish we could help more.

Kind of Late :( I'm sorry. But this was your solution.

Expand|Select|Wrap|Line Numbers
  1. my $wm = MainWindow->new();
  2. $wm->Button(-text => "Push Me", -command => \&new)->pack();
  3.  
  4. MainLoop();
  5.  
  6. sub new {
  7. $wm->Button(-text =>"New Button", -command => sub { exit(1); })->pack();
  8. }
Cheers :)
