QTableWidgetItem and formatting / input masks

I have a QTableWidget and for the contained QTableWidgetItem I need...

• to set input masks
• to format the displayed numbers correctly (e.g. 17.40 or 17,40)

But there is no setInputMask() available for a QTableWidgetItem?
How to format the numbers both during input and during displaying?

Thanks a lot!

Nobody? So is it not possible and I have to derive my own classes? :(

You might try to subclass QItemDelegate and reimplement QItemDelegate::createEditor() to make it set an input mask on the line edit. This should be enough, since QTableWidgetItems keep data as strings, so they won't reformat them after editing.

Thanks.
I am a bit disapointed that I have to code such a simple feature myself. I am just starting to learn Qt and sometimes it seems a bit... eh... low-ended
