Re: Dialog-like window?

[Micah Carrick <email micahcarrick com>]

I just make myself a dialog in Glade and then use gtk_dialog_run... the

result it returns just lets you know what button was clicked... once 
that is done you can take any information you want from the dialog 
before returning from the function. Below is a little example. Let's say 
you have a dialog made in glade called "dialog1" and on that dialog you 
have the stock "Ok" and "Cancel" buttons. Inside the dialog is an Entry 
called "entry1" where you want to get a string from the user.

You could then use this "dialog" as a function such as:  g_print("You 
typed: %s", dialog_get_string ());  or   gchar *some_string = 
dialog_get_string ();

gchar *
dialog_get_string ()
{
      GladeXML                *gxml = NULL;
      GtkWidget               *dialog = NULL;
      GtkWidget               *entry = NULL;
      GtkResponseType         response;   
      gchar                   *str = NULL;
     
      /* build dialog from glade */

      gxml = glade_xml_new ("gui.glade", "dialog1", NULL); 
     
      dialog = glade_xml_get_widget (gxml, "dialog1");
      entry = glade_xml_get_widget (gxml, "entry1");
     
      response = gtk_dialog_run (GTK_DIALOG(dialog));
     
      /*
      function sits here waiting for the user to click a button
      on my home-made dialog. Let's say that in this example I
      have "Ok" and "Cancel". I will just return str as NULL if
      the user clicks cancel, but will return the contents of the
      entry if they click "Ok".
      */

      if (response == GTK_RESPONSE_OK)
      {
              /* get value from the text */
              str = g_strdup (gtk_entry_get_text (GTK_ENTRY (entry)));

              /*
              this is also where you could get values to populate
              some struct you want to return to user
              */
             
      }    

      /* clean up */
      gtk_widget_destroy (dialog);
      gtk_object_unref (GTK_OBJECT (gxml));
     
      return str;
}
