Hi, if I want to call the value (as a string say) from the model (through a buttonclick from a pushbutton in the mainwidget), not through clicking in a cell in the QTableView but giving the information through a pair of integers. lets say row 0, column 0. Given the structure in the tutorial "Displaying tabular data in Qt5 ModelViews" https://www.pythonguis.com/courses/model-views/qtableview-modelviews-numpy-pandas/

I try value = self.model.data(0, 0, QModelIndex(), Qt.DisplayRole).toString()

But it doesnt work. (it crashes the app.)
