  26. --  This widget is a container that catches events for its child when its 
  27. --  child does not have its own window (like a Gtk_Scrolled_Window or a 
  28. --  Gtk_Label for instance). 
  29. --  Some widgets in GtkAda do not have their own window, and thus can not 
  30. --  directly get events from the server. The Gtk_Event_Box widget can be 
  31. --  used to force its child to receive events anyway. 
  32. -- 
  33. --  For instance, this widget is used internally in a Gtk_Combo_Box so that 
  34. --  the application can change the cursor when the mouse is in the popup 
  35. --  window. In that case, it contains a frame, that itself contains the 
  36. --  scrolled window of the popup.
