Forum: Ruby-Gnome 2 ListStore - possible to use String and Pixbuf image in the same field?

Hi,

I use something like this:

@list_store_party = Gtk::ListStore.new(
  Gdk::Pixbuf,
  String, # ID
  String, # Name
  String, # Profession
  String, # Number of Attacks.
  String, # Race
  String, # Gender
  String, # Level
  String, # Hitpoints
  Gdk::Pixbuf,
  Float   # Lifebar
)

Now I would like to display both a String and an Image (Gdk::Pixbuf) in
a ListStore field (displayed via a TreeView).

But is this possible?

More specifically, in this display of a "fantasy hero group", I would
like to display the gender ("male" or "female") but also show a little
gender icon right next to this text. But, I don't want to use a new
field.

So my question is, can I combine both String and Gdk::Pixbuf in one
field?

The 'store' cannot do that, of course, but a treeview column can have 
multiple cellrenderers. You have to think at a single cell like an hbox 
of cellrenderers.

For example (untested):

column = Gtk::TreeViewColumn.new("Gender")

pixbuf_renderer = Gtk.cellRendererPixbuf.new
column.pack_start(pixbuf_renderer, false)
column.set_cell_data_func(pixbuf_renderer) do |column, cell, model, 
iter|
  if iter[6] ~= /$m/i then
    cell.pixbuff = <male_pixbuff>
  elsif iter[6] ~= /$f/i then
    cell.pixbuff = <female_pixbuff>
  else
    cell.pixbuff = <unknown_pixbuff>
  end
end

gender_text_renderer = Gtk.cellRendererText.new
column.pack_start(gender_text_renderer, false)
column.set_attributes(gender_text_renderer, :text => 6)


You can have a look at the pygtk tutorial :

Yes - https://gist.github.com/1231530

Most of the work is done by the Gtk::TreeViewColumn, which can contain
multiple Gtk::CellRenderers.

Gtk::TreeViewColumn#pack_start(renderer, expand) &
Gtk:TreeViewColumn#set_attributes(renderer, attributes) then allow you
to configure what data it displays from the model (ie. the
Gtk::ListStore).

HTH,

Geoff

It works!

Thanks a lot for your help, Geoff and Simon!
