Re: (ichimunki) Re: Tk::JPEG

And of course you can define all of this at once:

  my $mw = MainWindow->new;
  my $photo = $button->Photo( -format => 'jpeg', 
                              -file   => 'test.jpg' );
  my $button = $mw->Button(-image => $photo)->pack();
  MainLoop;

I think it's a little strange to call a method on $button before you have declared $button with `my $button`. Maybe you patched your parser with a lookahead feature, "hey, do I declare this later, if so I can use it now, right?" :)	[reply] [d/l]

Brrr...you're right! I was way too quick with my answer! It should be this: `my $mw = MainWindow->new; my $photo = $mw->Photo( "photo" -format => 'jpeg', -file => 'test.jpg' ); my $button = $mw->Button(-image => "photo")->pack(); MainLoop;` [download] Jouke Visser, Perl 'Adept' Using Perl to help the disabled: pVoice and pStory	[reply] [d/l]

Now that's a trick worth knowing about! Keeping all image widgets as children of the MainWindow rather than in the widgets themselves makes managing them a lot easier (flipping images in Tk is a terrible memory leak unless done very carefully). It also allows for sharing a single photo widget among several other widgets if needed without having to reparent the original photo each time.	[reply]

Hi looking for something like this just to give me an idea I notice a missing comma it should be like this ? `my $mw = MainWindow->new; my $photo = $mw->Photo( "photo", -format => 'jpeg', -file => 'test.jpg' ); my $button = $mw->Button(-image => "photo")->pack(); MainLoop;` [download] Or am I wrong? Thanks with the example you help me nail the problem THANKS!!!!!	[reply] [d/l]
