Pango Attributes not being added to list
Greetings all, I am using Cairo/Pango to create pdf files. I wrote a functioning script on my desktop that correctly formats my Pango text. When transferring the script to my the server where it will be executed, my text is not properly formatting. It displays the default text format (times new roman, no decorations, no fore-ground color, default font size, etc). I have tracked the issue down to the fact that my Pango::Attr___ objects are not being added to the Pango::AttrList when executed on the server. They are being added correctly when executing the script on my desktop computer. I have attached the script which demonstrates that the attributes are in fact not being added to the list. On my desktop, the script produces: attributes: Pango::AttrFontDesc=SCALAR(0x299ebb4) Pango::AttrForeground=SCALAR(0x299ec34) On the server, the script produces: attributes: On a relevant side-note $layout-set_font_description( $font ) works as expected on both desktop and server. How this doesn't allow for changing of color, underlining, etc. Anyone have any ideas on what may be going wrong here? I realize the pango library is a bit dated, but I can't change it, and it *seems to me* like everything I want to use was supported in the version I have. I am not getting any error messages. I've thought of compiling the latest version into another folder - but at a cursory googling I see this may not be trivial. Hoping I may be able to get some feedback before I head down that road.

Subject: Printing/Creating PDf/Postscript
I am attempting to create reports using Gtk2/Cairo/Pango. My reports should be
able to write to a print operation, or
a cairo surface. This seems simple enough - just pass in the Cairo context you
want to write to. The problem I am running into is when draw text on a context
from a print operation - the text appears extremely tiny on the page (look at
print_op.pdf).
When drawing to a Cairo Surface - the output is as expected (see
surface.pdf/surface.ps).
surface_po_diff.pl is the script that created these files so you can run it
yourself.
What is going on here?
How can write this code, so the print_text function prints the same size on the
print operation and a cairo surface that I create myself.
Thanks in advance for any input!

RE: How to apply a theme to a perl gtk program
I use the theme selector available here:
http://gtk-win.sourceforge.net/home/index.php/Downloads , the file you want is
gtk2-themes-2009-09-07-ash.exe
Install this into the directory which you have installed Perl (on my system the
path is C:\camelbox).
I ship my entire perl directory with my application – so the end user will have
the themes installed. You can then give the user access to the C:\perl
path\gtk2_prefs.exe where they can change the look and feel of all Gtk2 apps
on their system - OR – to force your application to load a particular theme,
use this code early in your program, replacing “Unity” with whatever theme you
wish to:
my $mod = Gtk2::RcStyle-new;
$mod-Gtk2::Rc::parse_string(
qq[
gtk-theme-name = Unity
style user-font
{
font_name=Sans 10
}
widget_class * style user-font

RE: Gtk2::MessageDialog title
Of course. Gtk2::MessageDialog isa Gtk2::Dialog isa Gtk2::Window, so just just Gtk2::Window::set_title(). See below. I did actually look at Gtk2::Dialog but didn't see it there either. Should have just kept moving up?/down? the hierarchy. It is in Gtk2::Window - the parent of Gtk2::Dialog http://library.gnome.org/devel/gtk/stable/GtkDialog.html#GtkDialog.object-hierarchy But beware that the gnome human interface guidelines say that alert windows should have no title, as the title would normally just duplicate the text of the message... so, depending on what you're doing, you might actually want to blank out the title. http://library.gnome.org/devel/hig-book/stable/windows-alert.html.en Thank you very much for this, will check out the rest of the HIG to make sure I'm staying on track. For each widget in Gtk2 there is a man page; each man page has a HIERARCHY section, which shows the class ancestry for that type. Or you can look at the C api reference on gtk.org, which has the same info in a different format. Wasn't aware I could also refer to the C api reference. Thanks again.

Is this data within the ListStore or some other data passed to the method?

If you supply $user_data - then you it will be passed in as the last argument

Subject: Multiple menu popups with a single Gtk2::SimpleList
Hi,
I'm trying to display a popup menu in a Gtk2::SimpleList which can have
different menu choices depending on the data in the Gtk2::SimpleList.
The menu popup choices are driven by the value selected from a Gtk2::ComboBox.
There is a signal on the combobox that runs the popup sub below when the value
changes.
The first time the popup menu is invoked it displays correctly; displaying the
appropriate popup menu. The next time I select a different value from the
Gtk2::ComboBox and right click it a row in the Gtk2::SimpleList, it continues
to show the old popup in addition to the new one.
It's seems the Gtk2::SimpleList won't let go of menus you associate.
Here is a sample code snippet of what's not working.
sub popup {
my $menu;
if ($type eq 'type1') {
$menu = Gtk2::Menu-new();
my $menu_item = Gtk2::MenuItem-('Properties');
$menu_item-signal_connect(activate = sub {
# do something
});
$menu-append($menu_item);
} elsif ($type eq 'type2') {
$menu = Gtk2::Menu-new();
my $menu_item = Gtk2::MenuItem-('View');
$menu_item-signal_connect(activate = sub {
# do something else
});
$menu-append($menu_item);
}
$simple_list =signal_connect('button-press-event' = sub {
my ($widget, $event) = @_;
return FALSE unless $event-button eq 3;
$menu-popup (
undef,
undef,
undef,
undef,
$event-button,
$event-time);
}
$menu-show_all;
}
Correct, every time you call signal_connect, you are adding another callback to
be executed when the event happens.
You could try creating two menus, the decide which one to show in the callback.
my $menu1 = ...
my $menu2 = ...
$simple_list =signal_connect('button-press-event' = sub {
my ($widget, $event) = @_;
return FALSE unless $event-button eq 3;
if ( some condition ... ) {
$menu1-popup (
undef,
undef,
undef,
undef,
$event-button,
$event-time
);
}
else {
$menu2-popup (
undef,
undef,
undef,
undef,
$event-button,
$event-time
);
}
}
It's also worth noting you can disconnect signals.
my $handler_id = $simple_list =signal_connect('button-press-event' = sub {
... });
$simple_list-signal_disconnect($handler_id);

Gtk2::Ex::DateEntry and Gtk2::Ex::TimeEntry
Attached are two modules that I have recently finished - one for entering times and one for entering dates. Users can select and modify individual components of the date/time using the left, right, up and down keys. When a user sets the value by typing directly into the entry, the text will be parsed and transformed into a valid date/time - which enables users to type 2pm and have it result in 02:00 PM in the widget. See documentation for more details. Comments/suggestions/etc... welcome! Gtk2::Ex::TimeEntry is already available on CPAN. I just registered Gtk2::Ex::DateEntry - so it should be available in the near future. Hope these can be of use!

however for the comboboxentry, changed isnt acceptable as it fires on
every change (runs database query so not good performance)
No keypress events seem to be generated for CBE so are there any other
approaches that will fire only when whole field has been updated?
Connect to the changed signal of its Entry child?

Re: Subclassing Gtk2::GladeXML
I was sub-classing Gtk2::GladeXML (I have a print dialog for a large
number of reports, each report has its own 'options' dialog it can
display - which I have all in 1 glade file that I want to keep
separate from the rest of the program, and want to create some helper
functions that I want to access through the glade object.
The issue I ran into (and was able to solve) is that after sub-
classing Gtk2::GladeXML, I can't say
$self-get_widget('winReports');
I get an undefined value returned. However, if say it as so... it works
just fine.
Gtk2::GladeXML::get_widget($self, 'winReports');
Is this a bug or is does this operate this way for a specific reason?
A minimal example that exhibits this problem would go a long way towards the
answer. The immediate question i have is are you writing the code in some
odd way that causes the object to be blessed incorrectly?
Here is the beginning lines of the module.
package GTIMs::GUI::Dialog::Report;
use warnings;
use strict;
use Carp qw/carp cluck/;
use GTIMs;
use Glib qw(TRUE FALSE);
use Gtk2;
use Gtk2::GladeXML;
use Gtk2::Ex::DateEntry;
use base qw(Gtk2::GladeXML);
sub new {
my $class = shift;
my $self = bless Gtk2::GladeXML-new('lib/widgets/dlg_report.glade'),
$class;
$self-signal_autoconnect_from_package($class);
$self-get_widget('winReports')-{GUI} = $self;
$self-do_winReports_date_widgets_setup;
$self-do_winReports_treeView_setup;
$self-do_winReports_treeView_populate;
return $self;
}
I can get away with this, and get the behavior that I want. The no warnings;
use warnings; statements because I get a warning that get_widget has been
redefined...
no warnings;
sub get_widget
{
my ($self, $widget) = @_;
Gtk2::GladeXML::get_widget($self, $widget);
}
use warnings;
Im running windows 32, GTK+/Win32 Runtime Environment 2.8.20-1, ActiveState
Perl 5.8.8 build 819. (The distribution from lostmind.de/gtk-perl/)

RE: Re: Subclassing Gtk2::GladeXML
I've figured it out. I did have get_widget redefined in the package GTIMs. (It was exported). ___ gtk-perl-list mailing list gtk-perl-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-perl-list
Resource for building custom models
I have a custom TreeView in which I want to implement both a filter and sorting
functionality. Unfortunately Gtk2::TreeStore does not implement
Gtk2::TreeModelFilter. Currently, I get around this by overriding the following
routine in my custom TreeView.
sub set_model
{
my ($self, $model) = @_;
$self-{model} = $model;
$self-{filter_model} = Gtk2::TreeModelFilter-new($model);
$self-{filter_model}-set_visible_func(\_visible_func, $self);
$self-{sort_model} = Gtk2::TreeModelSort-new($self-{filter_model});
$self-Gtk2::TreeView::set_model($self-{sort_model});
}
I would like to create a custom model so I don't need to use this hack. I have
looked around for information on this - but it is sparse - and that I do find
is not all that informative. Does anyone know of a resource that I can use to
learn how to do this?

Drag Drop Icons Not Displaying (Windows)
My drag and drop icons appear as black silhouettes of what they actually should
be.
I'm curious to know if I am doing something wrong, or is this something that
other windows Gtk2-Perl users have experienced as well, or possible that this
is a bug that has since been resolved. I am using the installation available
from http://www.lostmind.de/gtk2-perl/ and running windows XP. I have tested
this on two machines - however they both used the packages from the site above
and both run WindowsXP.
Is anyone else using this installation and experiencing/not experiencing this
problem?
Here is a snippet of code that generates the issue:
$treeview-drag_source_set(['button1_mask'],['copy','move'],{target =
'STRING', flags = [], info = 0});
$treeview-signal_connect('drag-data-get',
\on_winScheduler_treeEmployee_drag_data_get);
$treeview-drag_source_set_icon_stock('gtk-dnd-multiple');

re: Displaying console output
You can put this line throughout your code or in a loop to update pending events (This is also good to use for updating progress bars.) # Run the main loop as long as events are pending Gtk2-main_iteration while ( Gtk2-events_pending ); You can also use POE (Perl Object Environment) which allows your program to multitask. Message: 1 Date: Mon, 21 Apr 2008 17:12:51 -0700 (PDT) From: Thomas Rosario [EMAIL PROTECTED] Subject: Displaying console output To: gtk-perl-list@gnome.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=us-ascii Hi All, I'm trying to build a GUI to show console output of an existing application. What I've done is 'clicked' signal_connect from Gtk2::Button will execute the application and save the output into a Gtk2::TextBuffer which will be displayed in Gtk2::TextView. At the moment, if the button is pressed, the whole GUI will 'freeze' and after the application execution is finished, the complete output is displayed. My question is, how can it be done so textview will be updated in real time with the console output instead of waiting the whole execution to be finished. Many Thanks! ___ gtk-perl-list mailing list gtk-perl-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-perl-list
Re: Textview not scrolling in Client
Just came across this at
http://live.gnome.org/GTK2-Perl/FrequentlyAskedQuestions#head-ca3eac3d2016b4893bea39bcf1c1b3565ce450ad
This should make sure that every time you add text to the widget,it is scrolled
to the bottom.
# create a mark at the end of the buffer, with right gravity,
# so that when you insert text, the mark always stays on
# the right (at the end).
my $end_mark = $buffer-create_mark ('end', $buffer-get_end_iter, FALSE);
# every time we insert text, scroll to that mark.
$buffer-signal_connect (insert_text = sub {
$textview-scroll_to_mark ($end_mark, 0.0, TRUE, 0.0, 1.0);
});

I have been struggling with this and I just cant seem to figure what
the problem is. I have this IRC client that wont scroll far enough
down to show the full text. Its rather hard to explain but I'll give
it a try:
when you get down to the bottom on the textview and you go to enter
a message such as:
John(10:00:00) I have to go to the story today and get some fruit.
And this message is the last one to be entered before the bottom of
the window therefore causing it to have to scroll down, the program
only shows the first line:
John(10:00:00) I have to go to the story
Forcing the user to scroll down to view the rest:
today and get some fruit.
You can see that this would be a problem when users are chatting,
having to always take your attention off of the session just to
scroll down and view the whole message. Currently the program uses
the code $chat_textview-scroll_to_mark where mark is defined as the
end iter of the buffer. I cant figure how to get this to work and
show the whole text without the user having to manually scroll down.
I am wondering if the word wrapping is causing it since this
behavior is true for a single unwrapped line. I would appreciate any
help on this since it seems like such a simple thing and I cant
figure it.
