When I tried to review the archives I got a 404 error. I used the link
from the Documents page, not the one on the FAQs page.

My rationale for making the observation was  that I signed up to the
list a few days ago and didn't get a single email from the list. I was
comparing that to debian mailing lists where I'm getting emails every
quarter hour.
I understand that that it is volunteer based project and in a stable
state, but I've just recently invested a lot of time learning what
turned out to be a dead project and would rather not do the same
again. At the same time I wanted to start learning the API and
migrating to Gtk2 as soon as possible.

That said, I asked if anybody was out there and now I got the answer.

Actually I believe I reviewed the resources in depth, which is was
what also prompted the question.

For some examples, there doesn't seem to be any recent tutorials
(latest I found with a date was 2006).  The main English version for
Gtk2-perl is half completed and is still in alpha.  The "search the
list archives link" 404s on me. (The one on the documentation page,
not the one I just found on the FAQ page). On the main page, the most
recent news leads to svn, while at svn.gnome.org you have the message
"All content on this site is obsolete. "

I'm just pointing out that the sourceforge site has a ghost-town feel
to it.  And as it turns up first on a google search, it could be
off-putting to people who may be migrating from Perl-Tk who are
evaluating the alternatives. I think as I have "new eyes" I'm going to
see the stuff you may be oblivious too.

I'm also offering to help out with the documentation as per the Intro.

Cheers.

I'm just an occasional user and initially I had many of the same
reactions you did. But the group has been very helpful and now I've
climbed at least part way up the learning curve. Now you're subscribed
to the list you'll soon see the effort that is put into maintenance and
enhancements.

As well as the gtk-perl documentation, you will need to become familiar
with the C documentation, because a lot of the perl docs don't repeat
info that is already in the C docs. Start with the doc links at
.

Also very helpful is the Python documentation, e.g.
 which is more extensive and
generally fairly easy to understand in a perl context.

> I'm also offering to help out with the documentation as per the Intro.

If there are broken links on the sourceforge site, I'm sure patches
would be welcome, or any other improvements you can suggest.

Oh, dear --- looks like markmail changed the link format.

http://perl.markmail.org/search/#query:list%3Aorg.gnome.gtk-perl-list

is what you want, i'll get that updated when i get home this evening.  Thanks
for pointing that out.

I think a difference between Tk and Gtk2 is that Gtk2 is based on a modern and
active upstream, while Tk is long stable and, well, kinda ugly by comparison.

You have to admit, the gnome project's switch to git is practically on the
heels of their switch to subversion.  It took us an embarrassingly long time
to get away from sourceforge cvs.

I think you're right, honestly.  We should knock down the cobwebs.  Please
report any broken links here.

Excellent.  Patches here.  Start anywhere you like.

Thanks for your reply.

I chose the Imendio package because I wanted a 'native' app rather
than using X11

As I understood it that Imendio package got me Gtk2, but not the Perl
bindings to it.

I was trying to use CPAN to get those Perl bits.

Here's all the output - all the steps previous to this worked fine.

http://pastebin.com/m21548cdc

Forcing the install didn't seem like the right answer  to me.

All comments appreicated,

Are you '/Users/rhult'?  I'm guessing not. Lots of test failures are
because files in that user's directory do not exist on your machine.

One thing about using Apple's Perl; if Apple decides to upgrade it,
things could break and there would be nothing for you to do but
recompile.  For this reason I prefer Perl from MacPorts.  Using
MacPorts also got me Perl 5.10 instead of Perl 5.8 (by hacking up the
Portfile for perl5 IIRC).

Stranger -- it looks like the file somehow got corrupted, with the

At any rate, it's fixed, now.

Function to return Gtk2::Table

[Peter E Dennis]

Hi All,

I am trying to create a function that when a button is clicked it will
create a table of widgets laid out in 2 rows x 9 columns and add it to
a vbox.

At the moment I am trying to do the following:

#!/usr/bin/perl
use Gtk2 -init;
use Gtk2::GladeXML;

# Read in glade file with gui
$gladexml = Gtk2::GladeXML->new('sscce.glade');

# Get main window vbox
$vbox1 = $gladexml->get_widget('vbox1');

# Get vbox to hold created tables
$vbox2 = $gladexml->get_widget('vbox2');

# Create a table of widgets
$table = &ret_table();

# Show the widgets?
$vbox2->pack_start_defaults($table); #get undefined error here...
$vbox2->show_all;
$vbox1->pack_start_defaults($vbox2);
$vbox1->show_all;

# Get main window from widget tree.
$main_window = $gladexml->get_widget('window1');

# Quit when user clicks on the close button/alt-f4 etc.
$main_window->signal_connect (destroy => sub { Gtk2->main_quit; });

# Maximise window
$main_window->maximize;

# Run main loop.
Gtk2->main;


sub ret_table
{
my $table = Gtk2::Table->new(2,9,FALSE);

# Title Row
my $lbl_num = Gtk2::Label->new("Num");
my $lbl_time = Gtk2::Label->new("Time/Session");
my $lbl_objectives = Gtk2::Label->new("Objectives/Learning Outcomes");
my $lbl_tasks = Gtk2::Label->new("Activities/Tasks/Content");
my $lbl_resources = Gtk2::Label->new("Resources");

my $tcol_sep1 = Gtk2::VSeparator->new;
my $tcol_sep2 = Gtk2::VSeparator->new;
my $tcol_sep3 = Gtk2::VSeparator->new;
my $tcol_sep4 = Gtk2::VSeparator->new;

# Entry Row
my $chk_num = Gtk2::CheckButton->new("1.");
my $e_time = Gtk2::Entry->new;
my $txtv_objectives = Gtk2::TextView->new;
my $txtv_tasks = Gtk2::TextView->new;
my $txtv_resources = Gtk2::TextView->new;

my $rcol_sep1 = Gtk2::VSeparator->new;
my $rcol_sep2 = Gtk2::VSeparator->new;
my $rcol_sep3 = Gtk2::VSeparator->new;
my $rcol_sep4 = Gtk2::VSeparator->new;

# Layout title row
$table->attach_defaults($lbl_num, 0, 1, 0, 1);
$table->attach_defaults($tcol_sep1, 1, 2, 0, 1);
$table->attach_defaults($lbl_time, 2, 3, 0, 1);
$table->attach_defaults($tcol_sep2, 3, 4, 0, 1);
$table->attach_defaults($lbl_objectives, 4, 5, 0, 1);
$table->attach_defaults($tcol_sep3, 5, 6, 0, 1);
$table->attach_defaults($lbl_tasks, 6, 7, 0, 1);
$table->attach_defaults($tcol_sep4, 7, 8, 0, 1);
$table->attach_defaults($lbl_resources, 8, 9, 0, 1);

# Layout entry row
$table->attach_defaults($chk_num, 0, 1, 0, 1);
$table->attach_defaults($rcol_sep1, 1, 2, 0, 1);
$table->attach_defaults($e_time, 2, 3, 0, 1);
$table->attach_defaults($rcol_sep2, 3, 4, 0, 1);
$table->attach_defaults($txtv_objectives, 4, 5, 0, 1);
$table->attach_defaults($rcol_sep3, 5, 6, 0, 1);
$table->attach_defaults($txtv_tasks, 6, 7, 0, 1);
$table->attach_defaults($rcol_sep4, 7, 8, 0, 1);
$table->attach_defaults($txtv_resources, 8, 9, 0, 1);

return $table;
}

However at the moment I get the following error:
Can't call method "pack_start_defaults" on an undefined value at
./main.pl line 18.

This is the line:
$vbox2->pack_start_defaults($table); # get undefined error here.

Is the table not being defined or is it the vbox?

Am I going the right way about this?

Many thanks,

Peter.

you don't have a vbox2 defined in your glade file, so that won't work.
looking at the code, since you are packing $vbox2 into $vbox1, perhaps
you meant to create a new vbox?
try something like this:

$vbox2 = Gtk2::VBox->new();

note that I haven't looked very much at this, tho this appears to at
least run.

Wow, that's embarrassing, must have forgotten to actually save the
glade file after adding vbox2.  Apologies for wasting your time.
