I anticipated this question :)
Here's what I'm trying to do ...
I've got an abstract 'window' class that handles loading windows from
a builder file, and attaching some convenience functions and stuff. I
want to save the state of various things in a SQLite database. For
example, GtkPaned positions are causing me issues on different
resolutions and DPIs. So I'd like to be able to do:
foreach my $item ( $window->{builder}->get_objects() ) {
if ( ref $item eq "Gtk3::Paned" ) {
my $name = $item->get_name;
my $state_name = $class . ':' . $name . ':position';
my $state = $globals->{config_manager}->simpleGet( $state_name
); # simpleGet fetches from a SQLite key/value pair config db
$item->set_position( $state );
}
}
... on startup. I'd of course have signals on the 'notify' signal of
each Gtk3::Paned to save the state each time it's altered ( with some
work-arounds for initial state ). This code would similarly have to
know the name of each item, so it could write it to the SQLite DB.
I've done this all manually for a couple of widgets ( ie by having
special code per widget ), but being able to do it generically as
above would be a far better solution. Thoughts?
