QTableView, default row height

Message 1 in thread

Hello,

the default row-height of QTableView is much larger than I would like.
How can I specify the row-height of *every* row,  instead of using
setRowHeight(row,height);?
Using a loop for new rows is absolutely not possible, because I'm handling
up to 500.000 rows and I'm sure it'd cause a noticeable delay.

Regards,

Daniel Albuschat

The row and column sizes are actually controlled by the headers. Even 
QTableview::setRowHeight() just makes calls to 
verticalHeader()->setSectionSize(). Check out 
QHeaderView::setDefaultSectionSize()

Thanks, it works. Hidden like that, I wouldn't ever have found it
myself, I think. :-)
