[Qt-interest] loading large data into QTable

[Ulf-Alexander v. Ceumern-Lindenstjerna]

Hi,

1) QTable? Are you still using Qt 3.x? 
2) Do you set the number of rows/columns before inserting the text?
AFAIR QTable automatically resized the table every time an item outside
the existing bounds was inserted which cost a lot of time.

Cheers, Ulf
