Printing under Mac OsX spools multiple pages #32

Open GoogleCodeExporter opened 8 years ago

What steps will reproduce the problem?
1.Create a diagram
2.Print

What is the expected output? What do you see instead?

Instead of printing one page, hundreds of pages are spooled very quickly.

Reported by user:

Downloaded pyNsourceGui for Mac OSX-- really like it. I imported some existing 
python code and your app successfully generated an accurate UML diagram.  I 
wanted to print one of the digrams to a PDF file, but when I selected 'print' 
the app started spooling a ton of pages. I canceled when it reached 398 pages. 
Is there a way to print the UML diagram?

Print module is pretty off the shelf stuff.  I wonder if the wxPython demos 
print ok under mac?

Current Workaround: You might just have to do a screenshot for now and print 
from there.

Aha - it seems that the print dialog is pre-populated with 9999 as the pages 
'to' range.  If you correct that in the gui print dialog back to 1 again, you 
are good to go.

Now I just have to figure out how to do this in code, or prevent it from 
happening in the first place.

See http://wxpython.org/Phoenix/docs/html/printing_framework_overview.html for 
some nice doco.

/Users/andy/Devel/pynsource/src/pyNsourceGui.py
calls
/Users/andy/Devel/pynsource/src/common/printframework.py
where I define my own
class MyPrintout(wx.Printout):

The calls are

 printout = MyPrintout(self.canvas, self.log)
 printout2 = MyPrintout(self.canvas, self.log)
 self.preview = wx.PrintPreview(printout, printout2, self.printData)

why am I creating 2 printout objects?

Seems to happen in the official wxPython demo.
So I posted
