SIGNALS
changed (Gtk2::Editable)
insert-text (Gtk2::Editable, string, integer, gpointer)
delete-text (Gtk2::Editable, integer, integer)
The "insert-text" signal handler can optionally alter the text to be
inserted. It may
· Return no values for no change. Be sure to end with an empty
"return".
sub my_insert_text_handler {
my ($widget, $text, $len, $pos, $userdata) = @_;
print "inserting '$text' at char position '$pos'\n";
return; # no values
}
· Return two values "($text, $pos)" which are the new text and
character position.
sub my_insert_text_handler {
my ($widget, $text, $len, $pos, $userdata) = @_;
return (uc($text), $pos); # force to upper case
}
· Return no values and modify the text in $_[1] and/or position in
$_[3]. For example,
sub my_insert_text_handler {
$_[1] = uc($_[1]); # force to upper case
$_[3] = 0; # force position to the start
return; # no values
}
Note that currently in a Perl subclass of a "Gtk2::Editable" widget, a
class closure (ie. class default signal handler) for "insert-text" does
not work this way. It instead sees the C level "($text, $len,
$pos_pointer)", where $pos_pointer is a machine address and cannot be
used easily. Hopefully this will change in the future. A
"signal_chain_from_overridden" with the args as passed works, but for
anything else the suggestion is to use a "signal_connect" instead.
