When I needed to store the state of my GUI, I wrote a routines which upon
encountering widgets converted them into their properties, for example:
if(
$src_ref =~ m/^Gtk2\:\:VScale\=/
or $src_ref =~ m/^Gtk2\:\:HScale\=/
)
{
$dst_ref = $src_ref->get_value;
}
elsif($src_ref =~ m/^Gtk2\:\:ToggleButton\=/)
{
$dst_ref = $src_ref->get_active;
}
else
{
$dst_ref = $src_ref;
}
.
So, rather than storing (useless in this case) references I stored the
properties from which the widgets could be reconstituted.
Of course, I have a reverse, i.e. a routine which reconstitutes widgets
from their properties.
I am doing all this not as hooks, but as independent routines, and call
Data::Dumper "as is".
Regards,
Sergei.
