Thanks Justin!
This is what I did
- Get the data from the QModelIndex that was edited
- Block signals on the model
- Loop through and set the data on the selected rows
- "Unblock" signals
- It seems like the tableview updates fine, but if I want to force an
update do I call reset() on the model to do so?
I want the Tableview to only accept floats. I guess one way to get this
behaviour is to use a float when I set the data of the QStandardItem?
By default I get two decimals on the tableview spinbox editor. How can I
access and set the min, max etc of the spinbox? My initial idea was to use
self.tableview.itemDelegate() to get a reference to the spinbox, but I am
quite new to this, what is the best way to go?
Best Regards,
Johan
