Re: Accessing a GtkTable's children.

["Craig Pemberton" <craigpemberton gmail com>]

I just discovered lookup_widget()! This makes life much easier. The code now
looks like the following. I'm not sure if this is best, but I used it by
getting the parent and then using lookup_widget() to look through it's
children.

I'm happy with this code now. Thanks again.

//This event is called when you press the enable/disable toggle button for
the estop.
void
on_toggletoolbutton_enable_toggled(GtkToggleToolButton *toggletoolbutton,
gpointer user_data)
{
   //We need the references to the widgets for the engage label and toggle
   GtkTable*  parent = (GtkTable*)
gtk_widget_get_parent((GtkWidget*)toggletoolbutton);
   GtkWidget* label_engage            = lookup_widget(parent,
"label_engage");
   GtkWidget* toggletoolbutton_enable = lookup_widget(parent,
"toggletoolbutton_enable");


   //These are the icons that show a connection and broken connecton
   GtkIconSize icon_size = gtk_tool_item_get_icon_size( (GtkToolItem*)
toggletoolbutton);
   GtkWidget *connect_image =    gtk_image_new_from_stock ("gtk-connect",
icon_size);
   GtkWidget *disconnect_image = gtk_image_new_from_stock
("gtk-disconnect", icon_size);


   //If off when pressed, turn it on! The icon should indicate that it is
connected.
   if (fstop_engaged == 0)
   {
       gtk_tool_button_set_icon_widget( (GtkToolButton*) toggletoolbutton,
connect_image);
       gtk_label_set_text (label_engage, _("Enabled"));
       //Redisplay the widgets
       gtk_widget_show ( (GtkWidget*) toggletoolbutton);
       gtk_widget_show ( (GtkWidget*) connect_image);
       gtk_widget_show ( (GtkWidget*) label_engage);
       fstop_engaged = 1;
   }

   //If on when pressed, turn it off! The icon should indicate that it is
disconnected.
   else
   {
       gtk_tool_button_set_icon_widget( (GtkToolButton*) toggletoolbutton,
disconnect_image);
       gtk_label_set_text (label_engage, _("Disabled"));
       gtk_widget_show ( (GtkWidget*) toggletoolbutton);
       gtk_widget_show ( (GtkWidget*) disconnect_image);
       //Redisplay the widgets
       gtk_widget_show ( (GtkWidget*) toggletoolbutton);
       gtk_widget_show ( (GtkWidget*) connect_image);
       gtk_widget_show ( (GtkWidget*) label_engage);
       fstop_engaged = 0;
   }

}
