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”
value = self.model.data(0, 0, QModelIndex(), Qt.DisplayRole).toString()
But it doesnt work.
(it crashes the app.)
