[pygtk] gtkunixprint.Printer Issue

[Vamsi Krishna Davuluri]

Hi all,

I'm in the process of writing a python program to do printing
by setting up a source file (pdf or ps) and using gtkunixprint
for it.
It's just test code:
So when i try to run this, the interpreter complains like this:

  File "printscript.py", line 37, in __init__
    gtkunixprint.Printer.__init__(self)
NotImplementedError: GetPrinter is an abstract widget

How do I get over this?
I cant create objects for that class, but this is standard,
can anyone tell me how I should Proceed?

My code is like this:
_PAGE_SETUP = None
_PRINT_SETTINGS = None

class PageSetup(gtk.Dialog):

    def __init__(self, title=None,):
        printDialog = gtkunixprint.PageSetupUnixDialog('Page Setup',
                                                        gtk.Window())
        printDialog.show_all()
        printDialog.connect('response',self.processResponse)

    def processResponse(self, widget, settings):
        _PAGE_SETUP = widget.get_page_setup()
        widget.destroy()


class GetPrinter(gtkunixprint.Printer):

    def __init__(self, title=None):
        gtkunixprint.Printer.__init__(self)
        self.connect('details-acquired',self.getPrinterName)

    def getPrinterName(self,obj,settings):
        pass#print self.get_name()

class PrinterSetup(gtk.Dialog):
    def __init__(self, title=None):
        printDialog = gtkunixprint.PrintUnixDialog('Printer Settings',

gtk.Window())
        printDialog.show_all()
        printDialog.connect('response',self.processResponse)

    def processResponse(self, widget, settings):
        _PRINT_SETTINGS = widget.get_settings()
        widget.destroy()

        if settings == -5:
           PrintJobObj = PrintJob()


class PrintJob:
    def __init__(self, title=None, printer=None, settings=None,
                      page_setup=None):
        PrinterOb = GetPrinter()
        printJob = gtkunixprint.PrintJob('lolcode',printer,
                                         _PRINT_SETTINGS,
_PAGE_SETUP)
        printJob.set_source_file('/home/iwikiwi/cupsinfo.txt')

Thanks,
Vamsi
