Re: [ruby-gnome2-devel-en] rake gem:build fails

[<Ra...@la...>]

Are you trying to build from git master?  I've done this several times 
recently on new Ubuntu installs and have not seen this error. I did see a 
problem with the --user-install flag, so I commented it out.  This is not 
your problem though.

Did you run the commands listed in the readme?

% git clone https://github.com/ruby-gnome2/ruby-gnome2.git
% cd ruby-gnome2
% gem install rake rake-compiler mechanize pkg-config cairo
% rake gem:build
% rake gem:install

Re: [ruby-gnome2-devel-en] Gtk::TreeStore#inserte is missing optional values parameter

[cedlemo <ce...@gm...>]

Hi detlef,

I tried to use Gtk::TreeStore#insert_with_values but without success. 
You should create an
issue here https://github.com/ruby-gnome2/ruby-gnome2/issues

I don't know how kou (Kouhei Sutou) would want to implement it :

using C code with gtk_tree_store_insert_with_valuesv 
(https://developer.gnome.org/gtk3/unstable/GtkTreeStore.html#gtk-tree-store-insert-with-valuesv)
or using ruby code with the Gtk::TreeStore#insert

Regards.

[ruby-gnome2-devel-en] Gtk::TreeStore#inserte is missing optional values parameter

[Detlef R. <det...@gm...>]

Hi,

with the old API it was possible to use

Gtk::TreeStore#inserte parent, position, values

where the values of the cells are given as an array or hash as optional 
last parameter. With the gi-bindings it is gone, but it was very handy.

Cheers, detlef

Re: [ruby-gnome2-devel-en] GTK3 TreeView set_select_function support?

[cedlemo <ce...@gm...>]

Jon,

it seems that Kou validated your work and merged your pull request so 
that should be ok.

Thanks for your contribution

Re: [ruby-gnome2-devel-en] GTK3 TreeView set_select_function support?

[<Ra...@la...>]

Hi Cedlemo,

Thanks again for your help.  I believe I was able to add this support 
correctly, matching the existing coding style.  I have created a pull 
request with my changes.

I was not sure how to create a test case for this as I'm not sure how to 
test this without opening a window.  If this is a deal breaker let me know 
and I will try my best to come up with something.

For what its worth, I was able to verify that it works the same as the 
Gtk2 version as my code is able to run unmodified.  It is now possible to 
prevent the selection in a Gtk TreeView in the case of unsaved changes, 
etc.

Jon

Hi Cedlemo,

Thank you!  I believe this is the clue I needed to move forward.  I will 
try adding the support myself and make a pull request if I'm successful.

[cedlemo <ce...@gm...>]

Hi jon,

First of all the maintainer of the projet (kouhei Sutou) won't be able 
to help you right know because he is busy preparing a talk for the 
RubyKaigi event
in japan. Nonetheless you should open an issue for this here 
https://github.com/ruby-gnome2/ruby-gnome2/issues and I am sure he will 
help you after that.

Furthermore, could you provide a minimum of code that reproduce the error.

 >Have I done something wrong
no

 >or is Gtk3's  #set_select_function really not implemented yet?
I think that that it is the problem

 >If not, is there something I can do to help resolve this?
Try to implement it maybe.

Look at this issue :
https://github.com/ruby-gnome2/ruby-gnome2/issues/596
and the resulting commit :
https://github.com/ruby-gnome2/ruby-gnome2/commit/c77eea299eb97e789b2e5e04ffe18c3cd1e2b8e3

My guess is that you will have to deal with the C part of the gtk3 module

[ruby-gnome2-devel-en] GTK3 TreeView set_select_function support?

[<Ra...@la...>]

The code ...

@class_tree.selection.set_select_function do |selection, class_tree_model, 
path, currently_selected|
  @controller.on_class_selected(selection, class_tree_model, path, 
currently_selected)
end

... produces this error ...

.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/gobject-introspection/loader.rb:551:in 
`invoke': TODO: <TreeSelectionFunc>(func) callback is not supported yet. 
(NotImplementedError)

I'm running off git master and am migrating a project from gtk2 to gtk3. 
Have I done something wrong or is Gtk3's  #set_select_function really not 
implemented yet?  If not, is there something I can do to help resolve 
this?  "gobject-introspection/loader.rb:551" didn't lead me to the code 
responsible for this and searching the code didn't provide enough of a 
clue.

Re: [ruby-gnome2-devel-en] Using GObject-Introspection

[cedlemo <ce...@gm...>]

I have looked at /usr/share/gir-1.0/Gnm-1.12.gir

and it seems that there are some dependencies that are not already done:

     Goffice
     Gsf

Hi again,

With the example below, I get a name error, having replaced Vte against
Gnm or Gnumeric.: 
“in `init': uninitialized constant Module::Loader (NameError)”

If I use GObjectIntrospection::Loader.new(self), the error reads.
-----------------
/var/lib/gems/2.1.0/gems/gobject-introspection-3.0.7/lib/gobject-introspection/loader.rb:167:in

Good morning again.

Merci beaucoup, ce tuyau est apprécié.

I will take a look at the tests and see, where they get me. There is
still some guesswork needed, simply for the fact that Gnumeric must
replace something else, that I can only vaguely identify in the tests
that I have quickly overflown. There may be more and I am patient. 

No worries.

Re: [ruby-gnome2-devel-en] Using GObject-Introspection

[cedlemo <ce...@gm...>]

I think that the example I gave you is more simple and better to start with:

https://github.com/ruby-gnome2/ruby-gnome2/blob/master/vte3/lib/vte3.rb

Just change the Vte name with Gnumeric:

require "gobject-introspection"
require "gtk3"

base_dir = Pathname.new(__FILE__).dirname.dirname.expand_path
vendor_dir = base_dir + "vendor" + "local"
vendor_bin_dir = vendor_dir + "bin"
GLib.prepend_dll_path(vendor_bin_dir)
vendor_girepository_dir = vendor_dir + "lib" + "girepository-1.0"
GObjectIntrospection.prepend_typelib_path(vendor_girepository_dir)

# You don't nedd this
#require "vte3/loader"

module Vte
   LOG_DOMAIN = "Vte"
   GLib::Log.set_log_domain(LOG_DOMAIN)

   class Error < StandardError
   end

   class << self
     def const_missing(name)
       init
       if const_defined?(name)
         const_get(name)
       else
         super
       end
     end

     def init
       class << self
         remove_method(:init)
         remove_method(:const_missing)
       end
       Gtk.init if Gtk.respond_to?(:init)
       loader = Loader.new(self)
       loader.load("Vte")
     end
   end
end


This is the most basic example.

Regards.

Howdy.

I have been a bit worried to put my question on the list, but your
responses keep me interested in GObject-Introspection.

You subclass a Loader and I have the immediate feeling, that this must
be crucial for all that follows. I do not have to understand all the
meta-programming which is anyway out of my reach to see clearer now.

Thank you very much.

Hi, like cedlemo I'm not much of an expert, but I have made a binding
for my own gobject-based library here:

  https://github.com/jcupitt/ruby-vips8

I used the binding for gst as a model, it's pretty simple to understand:

  https://github.com/ruby-gnome2/ruby-gnome2/blob/master/gstreamer/lib/gst.rb

Just copy-paste that and change the names to refer to the gnumeric
objects instead and it should work.

The gst binding does some extra renaming and overriding to make the
interface pleasant to use, you probably won't need that, at least to
start with.

[cedlemo <ce...@gm...>]

Hi Michael,

I am not  really an advanced contributor but Kouhei Sutou (which is the 
maintainer of ruby-gnome2) is busy at the moment so I will try to give 
you some hints.

There is not yet a good documentation. The best informations that you 
could find I think should be in the unit tests :

https://github.com/ruby-gnome2/ruby-gnome2/blob/master/gobject-introspection/test/

Have a look at the vte3 module which is really simple and follow the 
most common way to use GObjectIntrospection.

https://github.com/ruby-gnome2/ruby-gnome2/tree/master/vte3

and especially this file

https://github.com/ruby-gnome2/ruby-gnome2/blob/master/vte3/lib/vte3.rb

[ruby-gnome2-devel-en] Using GObject-Introspection

[Michael U. <mic...@so...>]

Good morning,

I try to understand GObject-Introspection to manipulate Gnumeric.
Apart from the method-listings and an almost empty ri-output, I find no
document dealing the topic.

A working Python equivalent, which by use of the gi module writes
'hello world' into a table cell is impossible to reproduce in Ruby as
the available documentation does not correspond, trial and error lead
nowhere.

Please point me at a more comprehensive overview. I see GI::Loader,
Gio2, GObjectIntrospection::Loader but cannot bring them together with
Gnumeric. In Python, using gi, a namespace 'gnm' is imported. If you
want to help me with a direct hint, instead, just tell me how this is
done in Ruby. I am not against finding a way on my own, but currently,
there is only big mist.

Thank you.

[ruby-gnome2-devel-en] FYI - assertion 'gtk_accel_group_from_accel_closure (accel_closure) != NULL' failed

[<Ra...@la...>]

I just ran across this assertion failure and wanted to document it 
somewhere in case someone else runs across it.

I have a Glade file containing a window organized with a layout containing 
a vbox.  The vbox contains two radio buttons with clicked signals defined. 
 For some reason the cell/column containing the vbox was wider than the 
others so I found that by specifying a width request of 1 on the vbox the 
widths seemed to look ok.

The problem was that as soon as I made this change I now get this 
assertion failure whenever I send :show to a Gtk::Builder object:

Gtk-CRITICAL **:IA__gtk_accel_label_set_accel_closure: assertion 
'gtk_accel_group_from_accel_closure (accel_closure) != NULL' failed

This appears to be related to the radio buttons in the vbox since I'm 
actually getting the assertion warning twice.

It was an easy fix for me because I knew exactly what I changed to produce 
the warnings - I just removed the width request on the containing vbox.

Hopefully this helps someone else who sees the assertion and wants a hint 
on where it might be coming from.

Re: [ruby-gnome2-devel-en] seeing GC-related crashes in 3.0.7, I think

[<jc...@gm...>]

I've made an example that shows the problem, but it is quite large :-( sorry.

This is a binding for the vips image processing library.

The libvips packaged for ubuntu is missing the typelib, unfortunately,
so you need to build from source:

https://github.com/jcupitt/libvips

You need:

./bootstrap.sh
./configure --prefix=/home/john/vips
make
make install

Then add vips to your library path and to GI_TYPELIB_PATH.

Then install this branch of this gem:

https://github.com/jcupitt/ruby-vips8/tree/gc-segv

so:

bundle install
rake build
gem install pkg/ruby-vips8-0.1.0.gem

Then run:

$ ./example/example3.rb
loop 0 ...
loop 1 ...
loop 2 ...
loop 3 ...
loop 4 ...
loop 5 ...
loop 6 ...
loop 7 ...
/home/john/packages/gems/gems/gobject-introspection-3.0.7/lib/gobject-introspection/callable-info.rb:31:
[BUG] rb_gc_mark(): 0x00000001ff1878 is T_NONE
ruby 2.1.2p95 (2014-05-08) [x86_64-linux-gnu]

Please let me know if you have problems setting this up, perhaps I can
make it smaller.

Could you show us a script that reproduces your problem?
We can't fix your problem without running the script on our

[ruby-gnome2-devel-en] seeing GC-related crashes in 3.0.7, I think

[<jc...@gm...>]

Hi, thank you very much for 3.0, it's added a couple of features I
needed and I'm now making progress on a goi binding for my image
processing library.

However I'm seeing crashes which seem to be related to
#<GLib::Param::Object:0x000000011be6e8> objects being GCd when they
should not.

I have an Argument class I used to track object args during setup. The
init looks like:

        def initialize(op, name)
            @op = op
            @name = name.tr '-', '_'
            @cls = op.gtype.to_class
            @prop = @cls.property name
        end

ie. I have a prop member which keeps track of the gobject property
during creation. After a GC, these pointers will sometimes become
invalid and I get crashes on lines like:

            value = Argument::arrayize prop.value_type, value

as it tries to use the prop. The C backtraces look like:

/usr/lib/x86_64-linux-gnu/libruby-2.1.so.2.1(+0x18a4b7) [0x7f8df89794b7]
/usr/lib/x86_64-linux-gnu/libruby-2.1.so.2.1(+0x18a583) [0x7f8df8979583]
/usr/lib/x86_64-linux-gnu/libruby-2.1.so.2.1(+0x6db13)

... etc
