I think we should use a supported language

I meant only for README files.

I have no objection for migrating to YARD. It is better that
we have a tool that imports documentations from GTK+ to YARD.
Most of Ruby-GNOME2 documentations are based on
documentations of GTK+.

Moreover, it is better that we can generate documentations
for GObject Introspection bindings such as Ruby/GIO2
automatically. .gir files provided by GObject Introspection
have documentations.

Hi,

do you mean it only for README file or for all docs? For the other docs
I am in favor to switch to YARD, because with YARD we get the types of
the parameters of methods and of the return values in a simple to pares
format. This is very useful for tools which analyses code written with
ruby-gtk.

Re: [ruby-gnome2-devel-en] Maintaining own fork of Ruby/GStreamer

[<ma...@sa...>]

I have been trying to run rake gem without success. It crashes on one of
requires that comes with rake-compiler gem.

I spend hours digging in the code because gem is installed and the same
requires called from irb work perfectly. As far as I remember I found out
that this happens due to the way how rake tasks spawn subcommands (probably
env is lost).

Maybe it's because I am using rvm but I had no problems with any other
piece of software.

I had no time to do further investigation and switched to Vala.

Hi,

you can build the gems in the following way:

cd gobject-introspection
rake gem    # builds the gem in pkg
cd pkg
gem install -l *.gem     # install the gem as root
cd ../../gstreamer
rake gem
cd pkg
gem install -l *.gem     # as root

first, I have tested it on debian testing and it works with ruby 1.9,
2.0 and 2.1 fine for me. From your back trace it doesn't look like a
ruby rsvg bug. I think it is in GLib or rsvg (both the C libs). Can you
install the debugging symbols for this two? It may give a more useful
back trace.

[ruby-gnome2-devel-en] Unable to use rsvg2 gem with Ruby 2

[Vlad K. <VK...@ji...>]

I haven't been able to use your rsvg2 gem with Ruby 2. i have tried 2.0, 2.1, and 2.1.2 and yet i always get a segmentation fault.

Here is the error dump: http://pastebin.com/aUR5L04b

and here is the very simple test file i am using: http://pastebin.com/vQb19QYT

I tested this on CentOS 6.5 with installing pretty much nothing other than rbenv, ruby and this gem.

Starting with a brand new fresh install of CentOS 6.5, i only ran the following commands:

——————————————

fresh install of CentOS 6.5
yum update
yum install git

--install rbenv and update PATH etc
git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec bash

yum install openssl-devel
rbenv install 2.1.2
rbenv global 2.1.2
gem install rsvg2

-- grab test file (same as in pastebin above) and execute
scp tools-qa.jiwiredev.com:/home/vkatz/test/test.rb
ruby test.rb

————————————

This gives me a segmentation fault.  doing the exact same as above but using ruby 1.9.3 works fine with no errors.

Any help would be greatly appreciated!  Thanks!

[ruby-gnome2-devel-en] Maintaining own fork of Ruby/GStreamer

[<ma...@sa...>]

Hi,

for some reason I would like to maintain my own fork of Ruby/GStreamer.

I don't need any other lib.

I've cloned the ruby-gnome2 repository, and typed the following

ruby extconf.rb glib2 gobject-introspection gio2 gstreamer
make

and the compilation succeeded.

How can I turn the outcome into gem, similar to official "gstreamer" gem?

Thank you,

[ruby-gnome2-devel-en] Gtk::Container subclassing

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

Hi,

I want to create a widget as a subclass of Gtk::Container. For this, in
C I have to overwrite some virtual functions: container_class->add,
container_class->remove, container_class->forall,
widget_class->get_preferred_width, widget_class->get_preferred_height
and maybe others.

How can I do this from ruby?

A GTK window is just shown when `Gtk.main` is called.
`show_all` sets flag to be displayed to all widgets, but doesn't
actually display until `Gtk.main` is called.

It seems that need to design such as the following:

* Do paging when an event occurred.

    ...
    FlickRaw.api_key=
    FlickRaw.shared_secret=

    @pixbufs = []

    results = flickr.photos.search(:tags => "tag", :per_page => 1)
    results.each {|currentresult|
      ...

      if myheight > 700
        ...
      end

      @pixbufs << currentpixbuf
    }

    update_image(@pixbufs.first)

      case event.keyval
      when Gdk::Keyval::GDK_KEY_Right

        @pixbufs.unshift(@pixbufs.pop)
        update_image(@pixbufs.first)
      end
    end

    # auto mode
    GLib::Timeout.add(1000) do
      @pixbufs.push(@pixbufs.shift)
      update_image(@pixbufs.first)
      true  # continue
    end
  end

  def update_image(currentpixbuf)
    if (defined?(@gtkimage)).nil?
      @gtkimage = Gtk::Image.new  :pixbuf => currentpixbuf
      add @gtkimage
    else
      @gtkimage.set_pixbuf(currentpixbuf)

    show_all

I don't tested it, but I think the problem is, that you while fetching
your images never go back to your Gtk main loop. This is necessary to
get the updates done. So after creating every Gtk::Image you should add
this line. I think, that it will help.

Gtk.main_iteration while Gtk.events_pending?

Re: [ruby-gnome2-devel-en] Displaying web images

[Michael B. <be...@ju...>]

Hi,

thanks for your help, this got me a big step further. Now I want to
display a slideshow: I am retrieving images from flickr into an array,
and now I want to iterate through those images with #each

My code shows only the last image. Seems like the window is not updated
while the initial code is run. I would like to force an update at the
end of each #each iteration. How may I do that? Is there a better way?

My current code is here:

Re: [ruby-gnome2-devel-en] Displaying web images

[Masafumi Y. <my...@gm...>]

Hi,

We can display web images in a GTK window by the following way:

    ...
    require "tempfile"
    ...
    image_path = Tempfile.open("display-web-image-in-gtk") do |tempfile|
      urlimage = open("http://rmagick.rubyforge.org/framed_clown.jpg")
      tempfile.write(urlimage.read)
      tempfile.path
    end

    posh = Gdk::Pixbuf.new(image_path)
    ...

This way is saving web images to local temp directory. When the script
is finished,
temp files will be deleted. And, doesn't need RMagick.

How about this?


Thanks,

[ruby-gnome2-devel-en] Displaying web images

[Michael B. <be...@ju...>]

Hi, 

I am trying to display an image from the web in a GTK window. Fetching
the image works, and displaying local images works too, but how can I
get my web image into an GTK::image object? Here's my code.
https://gist.github.com/anonymous/aa4f27aa135bc59bc792 -- Ruby complains
about an implicit conversion from nil to integer

I am trying to convert the image to a "well-behaved" blob using
Imagemagick/RMagick, because I have read in the documentation that
Gdk::Pixbuf accepts data input. Is there a better way?

Cheers

Michael

Hi, here is a simple example. From the appearing Dialog I want to
disable or hide some of the settings on the second page (page setup).

The reason why I want to disable some elements is, that I'm writing a
label editor (see at https://github.com/detlefreichl/etti ). And for
such a program it is really not useful if you i.e. can print double sided.

Cheers, detlef


#!/usr/bin/env ruby

require 'gtk3'

class Printer
    def initialize
        printOperation = Gtk::PrintOperation.new
        printOperation.n_pages = 1
        
        printOperation.signal_connect('draw-page') do |widget,
printContext, pageNumber|
            cc = printContext.cairo_context
            # drawing code
        end

        ret = printOperation.run :print_dialog
    end
end

printer = Printer.new
Gtk.main

Could you show a sample program to reproduce the case?

[ruby-gnome2-devel-en] disable widgets in print dialog

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

Hi,

I like to disable some of the settings in the print dialog, because in
my program it is not useful to change them, i.e. the paper size. The
dialog is created from Gtk::PrintOperation in the "run" method. Because
I found no way, to come from this point to the print dialog widget I've
tried to overwrite the initialize method of Gtk::PrintUnixDialog,
connect i.e. to the configure signal, search for the widget and  make it
insensitive. But my initialize is never called. Is there any other way
to get to this?

Re: [ruby-gnome2-devel-en] Next memory leak and infinity loop

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

Hi kou,

over the day at work I came to the same solution :-). Thank you!

I've looked into the gtk+ sources. The implementation is not that nice,
cause it takes a pointer of int as argument for the new order. So
checking the data for doubles like it happened in my example is useless,
cause even the length of the list can't be checked.

To get the safety for my programs I've extended the ListStore class in
the following way. It checked if the order index has the same size as
the list and if the indices are valid.

module Gtk
    class ListStore
        alias_method :old_reorder, :reorder
        def reorder order
            self_length = 0
            self.each {self_length += 1}
            raise ArgumentError, "invalid new_order size" unless self_length == order.length
            new_order = order.sort.uniq
            raise ArgumentError, "invalid index in new_order" if
                (new_order.length() != order.length() or new_order.last != order.length() -1)
            old_reorder order
        end
    end
end

Is it worth to include it in ruby gtk? It think an thrown exception is
always better then a program that eats all your memory and CPU time and
then crashes without a useful message.

Cheers detlef
