QTableWidget - setSortingEnabled

[bruccutler]

Hello,
I have enabled sorting using the setSortingEnabled call on a QTablewidget.

How do I control how it sorts. For example, I have a column with number that I want sorted numerically, not alphabetically, how do I do that? I also want to sort case-insensitive, rather than case sensitive, how do I do that?

For numerical sortiing, set the data as integers, not as text:

QTableWidgetItem* item = ...
// item->setText("2"); // <-- not like this
item->setData(Qt::DisplayRole, 2); // but this

QTableWidgetItem* item = ...
// item->setText("2"); // <-- not like this
item->setData(Qt::DisplayRole, 2); // but this

To copy to clipboard, switch view to plain text mode 

For case insensitive sorting, you might need to reimplement QTableWidgetItem::operator<().

Thanks for the reply.

"Roles" are a bit confusing. Where's a good reference on what Qt means by "roles"?

Again, thanks for the help.

• Item Roles
• enum Qt::ItemDataRole
