Hi all,

i want to plot values from a QTableWidget in qwt. Can anyone let me know how i can restrict the item types in every cells of my table to double values?

In the Qt4 doc, i saw QTableWidgetItem::Usertype. Maybe it's the solution to my problem but i don't know how to use it.

Thx a lot 4 the answers.

Create a custom delegate and return QDoubleSpinBox as editor. See the Spin Box Delegate Example (http://doc.trolltech.com/4.4/itemviews-spinboxdelegate.html) for more details.
