Re: Change the Behaviour of a Button in Tk::Dialog

ideally something like $dialog->get_button_by_text('OK');).

The perldoc fro Tk::Dialog says it has the same advertised widgets as Tk::DialogBox, which is shows the buttons available as B_"button-text". So in your case it would be

my $button_ok = $dialog->{SubWidget}{B_OK};

Hi ++zentara, as always you got the simplest and clearest solution, but: > The perldoc fro Tk::Dialog says it has the same advertised widgets as Tk::DialogBox I cannot find this explicitally said, I only see Tk::DialogBox in the `see also` section. When i read the doc of Tk::Dialog i've not understood what advertised was supposed to mean. It is a general Tk concept? L* There are no rules, there are no thumbs..

Hi Discipulus, right in the link you gave to Tk::Dialog it says: ADVERTISED WIDGETS Because Tk::Dialog is a subclass of Tk::DialogBox it inherits all the advertised subwidgets of its superclass: e.g. "B_button-text", where 'button-text' is a Button's -text value. Additionally, Tk::Dialog advertises: Yes, advertised widgets are a general feature of Tk, and most compound widgets will have them. See perldoc Tk::mega . All subclasses of mega widgets inherit the parent widgets advertised widgets. I'm not really a human, but I play one on earth. ..... an animated JAPH	[reply]

ah! i was reading `http://search.cpan.org/~ni-s/Tk/pod/DupName/Dialog.pod` instead of `http://search.cpan.org/dist/Tk/pod/Dialog.pod` !! Infact i'm at home with some line of fever but i was wondering if i was going blind and why i was not seing the same of you.. Nothing worst than read the wrong doc!

Thanks, that's exactly what I needed. Somehow, I overlooked the part in Tk::DialBox . The code is now shorter by 7 lines! ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l]
