viewcvs doesn't list libgnomeprintuimm, so I cannot link to that.  
However, the situation to which I allude above is with

Gnome::Print::UI::PrintDialog::run();

In the file "printdialog.h" in the libgnomeprintuimm library I 
downloaded (version 2.5.2), the run method  is listed in the class 
declaration but it is commented out.   The method  as it appears (also 
commented out) in printdialog.cc is shown below:

/*
int PrintDialog::run()
{
   gnome_print_dialog_run(gobj());
}
*/

As you can see, the function prototype specifies a return value, but the 
function returns nothing.  Because the method wrapper is commented out, 
and since the class is derived from Gtk::Dialog I made the assumption 
that the run method would return something meaningful, but as I said in 
my previous message, it does not seem to do that.  My perusal of the 
gedit source code indicated that a callback function was connected to 
the print dialog object to handle the different button presses in the 
dialog.  I am guessing that this is probably what should have been done 
in the wrapped version of the dialog since the buttons displayed by the 
print dialog are "PRINT PREVIEW", "PRINT", and  "CANCEL". 
Gnome::Print::UI::PrintDialog::run  returns the same value regardless of 
which of those buttons are pushed.

Is there any forecast about when the new cairo-based printing API will 
arrive?
