Displaying database info in QTableWidget

[deanhystad]

They are not windows. They are classes that put stuff in a window. I see this done in tkinter a lot, probably because tkinter does strange things like initialize tkinter and create a window at the same time (Tk()). In Qt I am more used to seeing a window class which is a subclass of a Qt class. Such as class MyMainWindow(qtwidgets.QMainWindow).

If Ui_MainWindow was a window you would not be doing this:

class Ui_MainWindow(object):
    def SetupUi(self, MainWindow):
        super().__init__()
        MainWindow.setObjectName("MainWindow")
        MainWindow.setWindowTitle("Phreesia Hardware")
        MainWindow.setWindowModality(QtCore.Qt.NonModal)
        MainWindow.resize(900, 350)
...
    window = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()2
    ui.SutupUi(window)

Instead your program would look more like this:

class Ui_MainWindow(QtWidgets.QMainWindow):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.setWindowModality(QtCore.Qt.NonModal)
        self.resize(900, 350)
...
    ui = Ui_MainWindow()
    ui.setObjectName("MainWindow")
    ui.setWindowTitle("Phreesia Hardware")

Differences are subtle, but making the UI_MainWindow class a window means it understands all the commands you can send to a window. I moved setObjectName and setWindowTitle out of the Ui_MainWindow class because now I can make two of these windows if I want and assign them different titles and give them different names.
