Can a sublcass of Wx::StaticBoxSizer handle events in wxPerl?

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

I'm trying to create a subclass of Wx::StaticBoxSizer as a reusable object that will handle its own events, as shown:

package my_sizer; use base 'Wx::StaticBoxSizer'; use Wx qw(:sizer); use Wx::Event qw(EVT_BUTTON); sub new { my $ref = shift; my $parent = shift; my $self = $ref->SUPER::new( Wx::StaticBox->new($parent, -1, 'Box label'), wxHORIZONTAL ); my $button = Wx::Button->new($parent, -1, 'Button'); $self->Add($button); EVT_BUTTON($self, $button, \&click); $self->SetSizeHints($parent); return $self; } sub click { Wx::MessageBox('Click!'); }

But I am getting the following error:

Can't locate object method "Connect" via package "Wx::StaticBoxSizer" at C:/strawberry/perl/site/lib/Wx/Event.pm line 38.

Does this mean that Wx::StaticBoxSizer and subclasses can't handle events? If so, is there another way to restructure my object so that it can handle its own events?

Thank you, monks.

    Sizers control layout of a window's children. Windows have a screen presence and manage events. You needs to base your class on wxControl or wxPanel. I couldn't find the difference between the two in practical terms when I was faced with the same question.

      Thanks for the guidance. Unfortunately, I tried your suggestion and now my control isn't even displaying correctly. Any ideas?

      package my_control; use base 'Wx::Control'; use Wx qw(:sizer); use Wx::Event qw(EVT_BUTTON); sub new { my $ref = shift; my $parent = shift; my $self = $ref->SUPER::new($parent, -1); $self->{sizer} = Wx::StaticBoxSizer->new( Wx::StaticBox->new($parent, -1, 'Box label'), wxHORIZONTAL ); $self->{button} = Wx::Button->new($parent, -1, 'Button'); $self->{sizer}->Add($self->{button}); EVT_BUTTON($self, $self->{button}, \&click); $self->SetSizer($self->{sizer}); $self->{sizer}->SetSizeHints($self); $self->{sizer}->FitInside($self); return $self; } sub click { Wx::MessageBox('Click!'); }

      (If you can't tell, I'm new to both wxPerl and Perl objects.)

      Thanks again.

        I don't see any problems from a visual inspection of the code, although I'm not fluent in Wx. I don't have Wx installed here to see the result for myself. How do you display it? What's not correct with how it's being displayed?
