= Dynamic User Interfaces Built With Glade

== Using Libglade

After you design your application in Glade, the next step is to load the user interface with Libglade. This library is used to parse the Glade user interface and create all of the necessary widgets at runtime.

To create a runable application from your Glade file is run the following command:

 ruby-glade-create-template browser.glade > browser.rb

This step will create the following output in the "browser.rb" file: 

((*browser.rb*))

 #!/usr/bin/env ruby
 #
 # This file is gererated by ruby-glade-create-template 1.1.4.
 #
 require 'libglade2'

 class BrowserGlade
   include GetText

   attr :glade

   def initialize(path_or_data, root = nil,
                  domain = nil,
                  localedir = nil,
                  flag = GladeXML::FILE)
     bindtextdomain(domain, localedir, nil, "UTF-8")
     @glade = GladeXML.new(path_or_data,
                           root,
                           domain,
                           localedir,
                           flag) {|handler| method(handler)}
   end

   def on_address_activate(widget)
     puts "on_address_activate() is not implemented yet."
   end
   def on_forward_clicked(widget)
     puts "on_forward_clicked() is not implemented yet."
   end
   def gtk_main_quit(widget)
     puts "gtk_main_quit() is not implemented yet."
   end
   def on_refresh_clicked(widget)
     puts "on_refresh_clicked() is not implemented yet."
   end
   def on_info_clicked(widget)
     puts "on_info_clicked() is not implemented yet."
   end
   def on_go_clicked(widget)
     puts "on_go_clicked() is not implemented yet."
   end
   def on_home_clicked(widget)
     puts "on_home_clicked() is not implemented yet."
   end
   def on_up_clicked(widget)
     puts "on_up_clicked() is not implemented yet."
   end
   def on_back_clicked(widget)
     puts "on_back_clicked() is not implemented yet."
   end
   def on_delete_clicked(widget)
     puts "on_delete_clicked() is not implemented yet."
   end
   def on_treeview_row_activated(widget, arg0, arg1)
     puts "on_treeview_row_activated() is not implemented yet."
   end
 end

 # Main program
 if __FILE__ == $0
   # Set values as your own application. 
   PROG_PATH = "browser.glade"
   PROG_NAME = "YOUR_APPLICATION_NAME"
   BrowserGlade.new(PROG_PATH, nil, PROG_NAME)
   Gtk.main
 end

:Currently there's a bug in  ruby-glade-create-template:

    I believe there is currently a bug in ((*ruby-glade-create-template*)). {{image_right("dialog-warning.png")}} The code it produces is missing the following two lines at the end of ((*initialize*)) method:

     window =****@glade*****_widget("window")   # <--- BUG: add these two lines
     window.show_all                        # <--- BUG: add these two lines

    Here is how ((*ruby-glade-create-template*)) creates the initialize method:

     def initialize(path_or_data, root = nil, domain = nil, localedir = nil, flag = GladeXML::FILE)
       bindtextdomain(domain, localedir, nil, "UTF-8")
       @glade = GladeXML.new(path_or_data, root, domain, localedir, flag) {|handler| method(handler)}
     end

    You should add the two missing lines into the above ((*initialize*)) method like shown here:

     def initialize(path_or_data, root = nil, domain = nil, localedir = nil, flag = GladeXML::FILE)
       bindtextdomain(domain, localedir, nil, "UTF-8")
       @glade = GladeXML.new(path_or_data, root, domain, localedir, flag) {|handler| method(handler)}

       window =****@glade*****_widget("window")   # <--- BUG: add these two lines
       window.show_all                        # <--- BUG: add these two lines
     end

After you fix this BUG you may run your output ((*browser.rb*)) program. Indeed, you would need to implement the all the callback methods, but one should be fixed immediately, namely: 

 def gtk_main_quit(widget)
   puts "gtk_main_quit() is not implemented yet."
 end

Change it to: 

 def gtk_main_quit(widget)
   Gtk.main_quit
 end
