Re^2: GTK2+glade and knowing who called

[ultibuzz]

in reply to Re: GTK2+glade and knowing who called
in thread GTK2+glade and knowing who called

no tutorial, im just experimenting with glade GUI

if i do the whole gtk2 gui in perl code, there is no problem getting what called,but while using a glade GUI,
it looks like it just calls the sub without any additional info

some example of the glade file

<child>
  <widget class="GtkButton" id="btnNum1">
    <property name="label" translatable="yes">1</property>
    <property name="visible">True</property>
    <property name="can_focus">True</property>
    <property name="receives_default">True</property>
    <signal name="clicked" handler="btnNUM_clicked"/>
  </widget>
</child>
<child>
  <widget class="GtkButton" id="btnNum2">
    <property name="label" translatable="yes">2</property>
    <property name="visible">True</property>
    <property name="can_focus">True</property>
    <property name="receives_default">True</property>
    <signal name="clicked" handler="btnNUM_clicked"/>
  </widget>
</child>

the sub is "btnNUM_clicked", which gets called without problem,but does not tell the code who called ;)

If changed to "btnNUM_clicked1..3", i know who called, but i want to avoid generating anonymous subs or endless prototyp's,
if there is a way within glade to pass the who called information.

you don't need anonymous subs if you use the event object

if there is a way within glade to pass the who called information.

I've never used it, don't know what kind of perl it generates, so I can't tell you what is going wrong

Not a very helpful link. Many broken links, and of the ones that worked, I didn't see anything showing a solution to the problem mentioned. (I may have missed a page, I can't be certain with all the broken links.

Really? I found one.

Ok, how do you know (how did you check)?

Its a good thing you the event object works :)

[ultibuzz]

the glade itself is describing the form in an XML file,it does not generate perl code.

example minimal code


use warnings;
use strict;
use Gtk2 -init;
use Gtk2::GladeXML;
my $gladexml = Gtk2::GladeXML->new('register_test.glade');
$gladexml->signal_autoconnect_from_package('main');

Gtk2->main;


sub btnNUM_clicked {
    print "yay clicked";
}

sub gtk_main_quit
  {
        Gtk2->main_quit;
  }


an alternative would be


use warnings;
use strict;
use Gtk2 -init;
use Gtk2::GladeXML;
my $gladexml = Gtk2::GladeXML->new('register_test.glade');
$gladexml->signal_autoconnect_from_package('main');

Gtk2->main;


sub btnNUM_clicked {
    my $self = $_;
    print "yay,you clicked $self";
}

sub gtk_main_quit
  {
        Gtk2->main_quit;
  }

sub btnNUM_clicked1 {
    btnNUM_clicked(1);
}

sub btnNUM_clicked2 {
    btnNUM_clicked(2);
}


this would work and can also be automaticaly generated,and inserted in the XML definition,
but that i would want to avoid, if there is a way from glade telling me who called the event.

Read perlvar#@_ and use @_, seems to work fine for me,  print "!!!@_\n"; yields

!!!! Gtk2::Button=HASH(0xc6fbf4) Gtk2::Dialog=HASH(0xc70094)

While you're at it read perlintro and the links from my first reply
