Tooltip on QTableWidget header

[ghorwin]

Hi there,

is there an easy solution to get tooltips when hovering over headers in QTableWidget or QTableView widgets?

My solution would be a combination of QHelpEvent and some coordinate calculation using indexOf() in the QHeaderView to find the correct header/column, but this looks to complicated...

Thanks,
Andreas

Did you try returning data for Qt::ToolTipRole from within your model in the headerData() method?

And with QTableWidget you could use header items:

QTableWidgetItem* headerItem = tableWidget->horizontalHeaderItem(0);
if (headerItem)
   headerItem->setToolTip("Hello, world!");

QTableWidgetItem* headerItem = tableWidget->horizontalHeaderItem(0);
if (headerItem)
   headerItem->setToolTip("Hello, world!");

To copy to clipboard, switch view to plain text mode

All these of course provided that either the header view or the basic view can handle it. QHeaderView is a very limited class when it comes to model/view features.

Yup, QHeaderView can handle tooltips out of the box.
