GTK3 ruby comboboxtext: remove text items

ruby-talk
1

Hello,

I am using GTK3 ruby 2.5. My problem I want do delete the list.

I already checked: remove_all, and combobox.model.clear

but nothing works.

How can I delete the Textlist.

Cheers

#!/usr/bin/env ruby

require "gtk3"
require "pry"

if str = Gtk.check_version(3, 10, 7)
puts "This sample requires GTK+ 3.10.7 or later"
puts str
exit
end

window = Gtk::Window.new("Gtk::ComboBox sample")
window.signal_connect("destroy") {Gtk.main_quit}

···

#
# Text only
#
combo1 = Gtk::ComboBoxText.new
["foo", "bar", "fuga", "hoge"].each do |val|
combo1.append_text(val)
end
combo1.active = 1

combo1.signal_connect("changed") do
p "combo1: #{combo1.active}, #{combo1.active_iter[0]}"
combo1.active = 1
end

# Show main window
vbox = Gtk::Box.new(:vertical)
vbox.add(combo1)
window.add(vbox).show_all

Gtk.main

The following works for me:

combo1 = Gtk::ComboBoxText.new
["foo", "bar", "fuga", "hoge"].each do |val|
  combo1.append_text(val)
end
combo1.active = 1

combo1.signal_connect("changed") do
  # p "combo1: #{combo1.active}, #{combo1.active_iter[0]}"
  if combo1.model.iter_first
    combo1.active = 1
  end
end

combo1.model.clear

# Show main window
vbox = Gtk::Box.new(:vertical)
vbox.add(combo1)
window.add(vbox).show_all

Gtk.main
