The good news first: I can launch my program again with 3.05 after a
few fixes. But this is what is logged at the console:

http://ssalewski.de/tmp/msg.txt

The deprecated warnings are not a problem for me, I had that already
when I port the application from gtk2 to gtk3. That is easy to fix. But
all the other messages? No idea currently.

For my current fixes:

class ColBox < Gtk::ComboBox
  attr_accessor :lock
  Col_Name, Col_Pixbuf, Col_Full_Name = 0, 1, 2
    def initialize
    store = Gtk::ListStore.new(String, Gdk::Pixbuf, String)
    Pet_Config::get_default_config.get_colors(Pet_Config::SCR_S).each{|sym, b, c|
      next unless s = Pet_Config::Color_Name[sym] # some colors may have no name/index, i.e. pin hot end color
      iter = store.append
      iter[Col_Name] = "(#{s})"
      iter[Col_Pixbuf] = Gdk::Pixbuf.new(Gdk::Pixbuf::COLORSPACE_RGB, true, 8, 12, 12) # (colorspace, has_alpha, bits_per_sample, width, height)
      iter[Col_Full_Name] = sym.to_s
    }
    super(:model => store)
    self.margin = 0 
    self.id_column = Col_Full_Name
    renderer = Gtk::CellRendererPixbuf.new
    self.pack_start(renderer, false)
    self.add_attribute(renderer, "pixbuf", Col_Pixbuf)
# self.set_cell_data_func(renderer) do |w, renderer, model, iter| # Gtk::ComboBox, Gtk::CellRendererPixbuf, Gtk::ListStore, Gtk::TreeIter
# r, g, b, a = Pet_Config::get_default_config.get_conf(Pet_Config::SCR_S)[iter[Col_Full_Name].to_sym]
# renderer.pixbuf.fill!((r * 255).round * 16777216 + (g * 255).round * 65536 + (b * 255).round * 256 + (a * 255).round)
# end

That is a problem when set_cell_data_func is not available :-(

And here:

class Properties_Widget < Gtk::Notebook
  attr_accessor :main_window # ask for redraw of object if property is changed
  def initialize(main_window)
    super()
    @main_window = main_window
    @grid_sensitive_spin_button_list = Array.new
    self.enable_popup = true
    self.add(w = Box_Widget.new(self))#, :tab_label => 'Box')
    self.set_tab_reorderable(w, true)

So I am not allowed to set the tab_label this way any more. What is the strategy
to find out how to do it now? In the last years, I did it mostly by guessing,
which can take really much time.


That is indeed much more trouble than expected. But what can we do? GTK 3.16 is what people
will use on Linux in these days, and that gives crashes with ruby-gnome2.2.5.
