Hi all.
Carrying on from my previous post on managing windows in an OO way and
not being able to destroy things ...
I've made an array of all objects & signal handler IDs that I get when I
connect to various signals, in both projects Gtk2::Ex::DBI and
Gtk2::Ex::Datasheet::DBI.
When I want to destroy an instance of the above, I do:
sub destroy_signal_handlers {
my $self = shift;
foreach my $set ( @{$self->{objects_and_signals}} ) {
$$set[0]->signal_handler_disconnect( $$set[1] );
}
return TRUE;
}
... where the 1st element in the array is the object, and the 2nd
element is the signal handler ID. In Gtk2::Ex::DBI, this is sufficient
... ie if I run the above sub, and then run the sub:
sub destroy_self {
undef $_[0];
}
the object is destroyed successfully. Cool :)
However in Gtk2::Ex::Datasheet::DBI, this doesn't work. This could very
well be because I'm using some custom cell renderers that set up their
own signal handlers, eg:
$editable -> signal_connect(key_press_event => sub { ... some stuff ...});
Do I have to clean this stuff up as well? The cell renderers aren't set
up in an OO way ( ie they can't see $self that the rest of
Gtk2::Ex::Datasheet::DBI sees ). This will make my above approach of
stuffing them in an array and disconnecting them later more complicated.
