( #3333=superdoc: print w/replies, xml ) Need Help??
Dear Monks, I want to write a subroutine for Tk::Canvas so that when it is called it will enable the user to view all elements of a Tk ::Canvas which would be something like the ViewAll() function of Tk::AbstractCanvas or something better (I don't want to use Tk::AbstractCanvas for some reasons...). The code I have written is something like this :
sub fit_to_canvas { my ($xt0,$yt0,$xt1,$yt1) = $_canvas{0}->bbox('all'); if($xt0 != "") { my ($x0,$y0,$x1,$y1) = $_canvas{0}->bbox('all'); $_canvas{0}->xviewMoveto($x0); $_canvas{0}->yviewMoveto($y1); $_canvas{0}->configure(-scrollregion => [$x0,$y0,$x1,$y1]); }## end of if not empty canvas }
But it does not seen to work properly and do what I need.... Any help will be highly appreciated in this regard.. Thanks, Kuntal

      Should cpanminus be part of the standard Perl release?
