[PyKDE] QTabWidget: Unbound symbols -> AttributeError?

[Greg Fortune]

I can reproduce on a 5500, but the explanation is simple.  The version of 
Qtopia running on the 5500 uses Qt 2.3.2 and the count property is not 
available in that version of Qt.

This is untested, but you might be able to get at the number of pages by

1) temp = currentPageIndex()
#This is the unknown..  Hopefully, negative indexs work like 
#they do for insertTab
2) setCurrentPage(-1) 
3) num = currentPageIndex() + 1
4) setCurrentPage(temp)

Morale of the story: Watch out for the different versions of Qt :)
