[Qgis-developer] Problem with large attribute tables

[Tim Sutton]

Hi

This is really a side effect of ticket

https://svn.qgis.org/trac/ticket/135

The table display needs to be redesigned to use qt interview
framework. I have some in progress work to do this, and martin has
been doing some similar work in python.

Regards

Tim
