Re: Native Gtk2-Perl apps on Mac OS X
Forgive me if someone's already posted about doing this: having installed the GTK+ package from Imendio (gtk-osx.org) on my Macbook I found installing the Gtk2-Perl mods pretty easy.

Re: Gtk2 perl graph saving
On 6/24/06, Subhrangshu Supakar [EMAIL PROTECTED] wrote: I am a newbie to Gtk2 perl, Iam not being able to save a graph generated by Gtk2::Ex::Graph::GD. I can tell you how to save the image that is being generated. The $graph-get_image($data) actually gives you a Gtk2::EventBox with a Gtk2::Image inside it. I took this approach because I wanted the graph to respond to 'events' (mouse movements etc) and the Gtk2::Image itself did not do that. I think what you can do is as follows. $graph = Gtk2::Ex::Graph::GD(...); # Get the Gtk2::Eventbox out my $eventbox= $graph-get_image($data); # Now pull the Gtk2::Image from inside the $eventbox. my $image = $graph-get_child; # Now I pull the Gtk2::Gdk::Pixbuf from inside the Gtk2::Image my $pixbuf = $image-get_pixbuf(); # Now I can write that pixbuf to a file $pixbuf-save($filename, 'jpeg', quality = '100'); But of course, all this just helps you to save the image alone.

TreeModelFilter issues
In the following code, I have a simple list with a checkbox and a text field. The text field is being filtered using a TreeModelFilter (type in something into the Entry and press search) My trouble is with check-marking a particular row after any kind of filtering has been applied. Before filtering, the check-marking works fine. After filtering, clicking on the check-box doesn't put a tick-mark into the particular check-box on that row. Sometimes it puts a checkmark on another row. My guess is that since the TreeModelFilter is hiding rows, the clicking of check-box is probably being captured by a hidden row. Some kinda mis-alignment like that. But isn't that a bug ? May be the bug is not in perl bindings but in the gtk code. Any comments ?

You're adding the IconView to a box and then adding the box to a ScrolledWindow with a viewport. Is that really what you want? If this works correctly, it will cause the labels to scroll with the IconView, which tends to be rather disorienting. That actually is the behaviour that I am seeking. I am trying to cook up a photo manager app and I want the right side pane in that to behave like what picasa does. Right side pane will show each photogroup with a header-label and a list of thumbnails under them. I want all of these sets to be in a scrolledwindow and when I scroll, the label along with the thumbnails should scroll to show the next photogroup. I am using iconview for the thumbnail set. If that layout is really what you want, you can get the viewport to behave as expected by giving a size request to the icon view (e.g., $iconview-set_size_request (100, 400)), but this then requires you to come up with some numbers. Is there anyway to turn off the native scrolling ?

Issues with iconview
I am encountering a strange problem with the iconview widget. Attached
are two scripts to demonstrate the case.
In the first one, I am creating a pixbuf from a stock_icon and adding
it to an iconview and then adding it to a scrolledwindow. Everything
works as expected here.
In the second one, everything is same except that I create the pixbuf
from a jpeg file. This time the scrolledwindow doesn't behave quite
well. I don't see the scrollbars. When I expand the window and reduce
it, the label Two starts hiding the iconview area.
I have fooled around with the VBox packing flags ('expand', 'fill') to no avail.

Announcing Gtk2::Ex::GraphViz - 0.01
Gtk2::Ex::GraphViz is a Gtk2 wrapper to the GraphViz.pm module.
GraphViz package can be used to produce good-looking network graphs.
Wrapping with Gtk2 allows those graph images to respond to events such
as mouse-over, clicked etc.
By implementing callbacks to the respective signals, you can create
fairly interactive network graphs. For example, when the user
double-clicks a node, you can open up a widget that contains
information on that node.
use GraphViz;
use Gtk2::Ex::GraphViz;
# First do all the work in GraphViz.pm
my $g = GraphViz-new;
$g-add_node('London', shape = 'box', fillcolor ='lightblue',
style ='filled',);
$g-add_node('Paris', label = 'City of\nlurve', );
$g-add_edge('London' = 'Paris');
# Now the actual Gtk2::Ex::GraphViz portion takes over
my $graphviz = Gtk2::Ex::GraphViz-new($g);
$graphviz-signal_connect ('mouse-enter-node' =
sub {
my ($self, $x, $y, $nodename) = @_;
my $nodetitle = $graphviz-{svgdata}-{g}-{g}-{$nodename}-{title};
print Node : $nodetitle : $x, $y\n;
}
);
TODO:
This is just an alpha release. Only mouse-enter, mouse-exit events are
implemented. I plan to implement clicked events soon. Also performance
kinda sucks on low end machines. I'll throw in a better search
algorithm to improve the performance.
And, by the way, its LGPL.
Feedback / Suggestions welcome.

ANNOUNCE: Gtk2::Ex::DateRange
Gtk2::Ex::DateRange is a simple special purpose widget for specifying a range of dates. (For example, [after '1965-03-12' and on or before '1989-02-14']). I wanted something more than just two plain old Gtk2::Entries for this purpose. So I wrote a little high level widget with 'usability' as the foremost criterion.

Long running DBI queries (gtk2 , threads)
I want to have my perl-gtk app query a database using DBI and display
the query results. Some of the queries can take minutes to run and a
naive implementation would mean all GUI interaction was blocked until
the $dbh-execute returned.
This seems to be a fairly common problem.

http://mail.gnome.org/archives/gtk-perl-list/2005-August/msg00140.html
In my case, I've cooked up a solution using ithreads. It worked fine
for me (on win32). So I decided to abstract away all the thread
related code into a separate package so that the main code will remain
fairly clean (no thread related code in the main)
Attached is the new (beta) package. MyThread.pm. An example is also attached.
# - #
USAGE:
# - #
The usage is fairly straightforward.
Use the Cregister_sql to register a sql to be executed and a
call_back to be called post-execution. You get to refer to this thing
by a name so that you can call it later.
$mythread-register_sql('some name', \call_sql, \call_back);
Later on, this registered sql can be triggered by calling
$mythread-execute('some name',[list of parameters]);
$dbh and $sth cannot be 'shared' between threads. So I have to shuttle
parameters and resultset between threads to get this thing going. Of
course, I am using CStorable qw(freeze thaw) to exchange data
structures.
sub call_sql {
my ($dbh, $sqlparams) = @_;
my $params = thaw $sqlparams; # Don't forget to thaw
my $sth = $dbh-prepare(qq{
# my complicated long query that takes a long time to
complete
select a.field2, b.field2 from table1 a, table2 b where
a.field1 = b.field1
and a.field2 like ?
});
$sth-execute('%'.$params-[0].'%');
# We HAVE TO load all required data into an array and send it
back
# Main thread does not have access to the $dbh and $sth...
# Atleast I haven't figured out a way to 'share' these handles
my @result_array;
while (my @ary = $sth-fetchrow_array()) {
push @result_array, [EMAIL PROTECTED];
}
return [EMAIL PROTECTED];
}
The C@result_array that was created cannot be meddled with from the
main thread. Instead, you'll get a frozen version of that through the
call_back function.
sub call_back {
my ($result_array) = shift;
@{$slist-{data}} = ();
foreach my $x (thaw $result_array) { # Don't forget to thaw
once more
push @{$slist-{data}}, @$x;
}
}
# - #
This stuff works for me in my toy app on win32. If any one sees
pitfalls with this approach please do let me know. Like I said before,
I am still a newbie on threads(gtk2-perl). This is a problem which I
'have to' solve in my app and the approach seems good enough according
to me.
I can't use pipes because they don't behave quite well on win32. Also,
spawning off a new process to do dbi query may be ugly.
If no one sees issues with this approach, I'll load this into cpan

Well, after spending a bit more time on this, I concluded that using pipes on win32 is definitely impossible. So I decided to model the functionality that I need using threads instead. I have re-written the FAQ example to use threads instead of pipes. The inspiration of course was from muppet's code at http://mail.gnome.org/archives/gtk-perl-list/2003-November/msg00028.html I am attaching the code. If no one sees issues with it, I can add this as a recipe.

Using Gtk2::Helper-add_watch() or Glib::IO-add_watch
I am trying to build the functionality where my app issues an sql statement and constantly updates a progressbar (or some other form of feedback) while the sql is being executed by the database. I know this has been discussed here before and one of the solutions was to fork the sql execution into a separate thread using Gtk2::Helper-add_watch() or Glib::IO-add_watch. Unfortunately, the docs for these APIs didn't help me too much. Google search didn't return much either. Any good samaritan here willing to share some code snippets on how to achieve this ;) ? I promise to add a recipe for this once I figure it out with a lil' help from you folks.

Thanks !
The FAQ however has some minor syntax errors. I found it being discussed here
http://mail.gnome.org/archives/gtk-perl-list/2005-March/msg00107.html
I tried the code that muppet has posted in that thread. Somehow that
quite doesn't work for me either . I'm on windoze XP. I am wondering
if it has anything to do with the fact that I'm on win32.
The behaviour I notice is as follows. My textview buffer doesn't get
anything written into it. My command prompt gets filled with
reading... read messages (with no sleep in between) and it seems to
be in an infinite loop. (no stopping after 9 seconds).
Am I missing something here ? Does this have to do with buffering
related to open(FILEHANDLE, EXPR).
Here is the code that I'm running
#!/usr/bin/perl -w
use strict;
use Gtk2 -init;
my $window = Gtk2::Window-new;
my $scroll = Gtk2::ScrolledWindow-new;
my $textview = Gtk2::TextView-new;
my $buffer = $textview-get_buffer;
$window-add ($scroll);
$scroll-add ($textview);
$window-show_all;
$window-signal_connect (destroy = sub { Gtk2-main_quit });
open(IN, q^perl -e '$|++; for $i (0..9) { $sum+= $i; print Line $i:
sum = $sum\n; sleep 1;}'|^)
or die Failed running perl subprocess\n;
Glib::IO-add_watch ( fileno(IN), ['in', 'hup'], sub {
my ($fileno, $condition) = @_;
if ($condition eq 'hup') {
warn done\n;
close IN;
return 0; # uninstall
}
warn reading...\n;
my $line;
sysread IN, $line, 1024;
warn read $line\n;

Gtk2-Ex-Graph-GD-0.02 is not available
Gtk2::Ex::Graph::GD is a simple wrapper around the good-looking GD::Graph module. Wrapping using Gtk2 allows the GD::Graph object to respond to events such as mouse movements.

I'll add some basic stuff like legend-placements, legend-hiding, tooltip on lines, support mixed graph types etc soon. I'll resist hard to prevent over-engineering :) The code is in sourceforge at http://cvs.sourceforge.net/viewcvs.py/gtk2-perl-ex/Gtk2-Ex/Graph/GD/ You should also be able to pickup this release from CPAN http://search.cpan.org/~ofeyaikon/ once its indexed (in a few hours).

Re: Different graphing options

Re: Programmatically popup a tooltip
This doesn't seem very satisfactory, but despite a
good amount of searching I can't see how widgets and tooltips
interface with each other, so there seems not to be any easier
approach.
I tried a ugly hack like this...
my $TOOLTIP = Gtk2::Window-new('toplevel');
$TOOLTIP-set_decorated(0);
$TOOLTIP-set_type_hint('GDK_WINDOW_TYPE_HINT_DOCK'); # I don't if
this is the best hint
$TOOLTIP-add(Gtk2::Label-new('hello world'));
$TOOLTIP-set_default_size(100, 10);
$TOOLTIP-set_position('mouse');
$TOOLTIP-modify_bg ('normal', Gtk2::Gdk::Color-parse('yellow'));
my $image = Gtk2::Image-new_from_pixbuf (loaded from a png)
my $ebox = Gtk2::EventBox-new;
$ebox-add ($image);
$ebox-add_events (['pointer-motion-mask', 'pointer-motion-hint-mask']);
$ebox-signal_connect ('motion-notify-event' =
sub {
my ($widget, $event) = @_;
my ($x, $y) = ($event-x, $event-y);
if ($x 10 $x 100 $y 10 $y 100) {
$TOOLTIP-show_all;
} else {
$TOOLTIP-hide;
}
}
);
Two things that I absolutely hate about this are.
1. I don't like the location where the pop-up shows up. ('mouse') . I
wish that could be better.
2. Since this is another window altogether, it'll show up on my win32
taskbar (I guess same for other OS too). That's ugly for such an
insignificant tooltip popup window :)

Re: Different graphing options
Well, that was lot of information and it took me a while to digest it all. Narrow the scope a bit; what's more important? I am looking for excel-like charts for a business application. Therefore no immediate need for math functions etc. One functionality I would love is a 'tool-tip' that would pop-up with the value of the data-point when the user moves the mouse on a data point (like excel). Other than that, pretty much some bars, lines, pies etc. Speed is definitely a concern 'cos I want to generate the graphs dynamically based on the user selection of data-points (data selection will be done using TreeView or something). Quality is not that big a concern b'cos my idea of the graph is to just to give a quick visual cue to the user. Just for the record, gnuplot works very well on win32 (IMO, anyway) Yes ! Gnuplot indeed seems to work fine on win32. I've been playing with it for a couple of days. I haven't done any heavy lifting yet but so far it seems pretty good. Chart::Graph::Gnuplot (part of Chart::Graph) I downloaded this module and played with it. Needs some polishing to run on win32. I looked at the source code and my guess is that it can be easily patched to work on win32. it looks like the gtkextra-2.0 API is a little more binding-friendly, but i'm a little unnerved that they don't appear to have released out of cvs. On a slight offnote, I've seen that they've recently patched the gtksheet. I guess development is not as dead as I thought to be in that part of the world. But still their release cycle seems mysterious to me too. There's also Ploticus I'm yet to play with Ploticus. But it may actually fit my needs from what I read on their site. I guess Grace and jpgraph may meet similar needs too. If I go that route, I just have to decide which one is cleaner to wrap in perl and pipe to Gtk2. To summarize, I haven't yet decided which path to take.

UI for scheduling events (appointments)
One of the apps that I am writing requires a UI to specify a recurring set of 'events' (events in the calendar sense). Like a meeting appointment for example, on all mondays and thursdays for the next 3 months. Kinda like Evolution/Outlook meeting schedule. Ripping anything from Evolution may be too heavy weight for me. So I am thinking of writing a gtk2-perl widget to meet this need. I googled around a bit and finally decided to choose Flavio's DateTime::Event::ICal as the backend spec. So my aim is now to write a UI for the DateTime::Event::ICal module. Since there is quite a bit of UI design involved, I am considering using glade and Gtk2::GladeXML. But I am wondering what is a clean approach to package the xml file in the module. For example, if I want to generate a cpan dist, is it normal to package a glade xml file along ? Or would you recommend writing widget packing perl code instead of gladexml ?

Gtk2::Ex::RecordsFilter - 0.03
Gtk2::Ex::RecordsFilter is a high level widget to browse reasonably large amounts of relational data and select a subset of records. This widget is inspired by the song browser of iTunes/Rhythmbox. I believe that this widget can be used in other areas too. For example, in a business application. (May be alongside the Gtk2::Ex::TreeMaker.) The source code is available from cpan. http://search.cpan.org/~ofeyaikon/Gtk2-Ex-RecordsFilter-0.03/ I have added an example to the examples folder. The non-trivial case is one in which a child node has two parent nodes. Without clicking anywhere else, click on the Knockin' on heaven's door in the 'Song' window and then add that to selection to see what I mean.

Gtk2::Ex::TreeMaker - 0.04 is now available !
The version 0.04 can be downloaded from http://sourceforge.net/project/showfiles.php?group_id=121463package_id=142803 INTRODUCTION: Gtk2::Ex::TreeMaker is my humble attempt to create a generic high-level widget using the Gtk2::TreeView. This widget was written with typical business applications in mind. Typically in business applications, users like to view data in a spreadsheet kind of display. (Columns represent timeline(typically) and rows represent measures like sales/inventory/blah/blah). But, the data itself may be stored internally as relational records. This widget will accept a relational feed of records and automatically convert it into a hierarchical treeview using the Gtk2::TreeView. The process involves invoking some recursive functions to build a TreeModel and populate it. Also, since the spreadsheet itself can be rather long horizontally, the widget also has a IFreezePane capability. For example, here is some sales info (stored internally in a relational database) - Region, City, Product, Date, Quantity - Texas, Dallas, Fruits, Dec-2003, 300 Texas, Dallas, Veggies, Jan-2004, 120 Texas, Austin, Fruits, Nov-2003, 310 Texas, Austin, Veggies, Feb-2004, 20 - This widget can present the same data in a hierarchical(/spreadsheet) kinda display as shown below. -- Prod / Date Nov-2003 Dec-2003 Jan-2004 Feb-2004 -- Texas Dallas Fruits 300 Veggies 120 Austin Fruits310 Veggies 20 -- CHANGES: - This is the first serious release. - Resolved packaging issues. (META.yml, MANIFEST) - Now you can specify attributes to each record. Such as editable, underline etc. (Check out the examples folder) TODO: - Build the tree using a custom implementation of Gtk2::TreeStore (perhaps!)
