On approximately 5/9/2009 12:28 AM, came the following characters from
the keyboard of Edwin Marshall:
I have a QTableView that displays the contents of a model with over
3000 rows, each with 11 columns. I'd like to the original size of
these columns to be no larger than the content within them, but
setting their resizeMode's to QHeaderView.resizeToContents causes the
tremendous slow downs (where originally the data would load in two
seconds, using this mode causes the data to be loaded after about a
minute and a half). Is there some faster alternative?
I'm thinking of calculating the width by using the length of the
largest item in the column, but that would require me to know how
large in pixels each character is.
Any suggestions? Mean while, I'm going to stare at the Qt
documentation for a couple more hours to see if I find something.
If you have nothing better to try, I'm wondering if unsetting
QHeaderView.resizeToContents, then loading the data, and then setting it
again, could provide a speedup? If it is successful, let me know. I'm
very novice to Qt, and working on a non-Qt project at the moment, or I'd
try it for you.
