PyQt custom widget not showing

Question

I\'m new to PyQt.

I\'m trying to put a QTableView in a class, so I can define it\'s behaviour in the class without mixing it with all the other code, but when I do so it

Answer 1

You defined Tableas a QWidget with an attribute self.view=QTableView. But you didn't define a layout on Table, so it will be displayed as an empty widget.

You either have to define a layout for Table, and add the view to it, or directly add the view to the main window's layout:

class MyWindow(QWidget):
    def __init__(self, *args):
        QWidget.__init__(self, *args)

        tablemodel = MyTableModel(my_array, self)
        table = Table(tablemodel)

        layout = QVBoxLayout(self)
        layout.addWidget(table.view)  #add view instead of table
        self.setLayout(layout)

A third way is to change the definition of Table: you could subclass QTableView instead of QWidget (code not tested):

class Table(QTableView):
    def __init__(self, model, parent):
        super(Table,self).__init__(parent)
        self.setMinimumSize(300,300)
        self.setModel(model)
