load uic file

[MaMo]

I have found the following topic, which i would like to adopt in part:
https://forum.qt.io/topic/124028/display-custom-list-of-files-in-qtreeview-using-qfilesystemmodel-or-qabstractitemmodel/6

Can someone please tell me how to convert the code so that the data is output to a specified UI file?

@MaMo
There is no output or data in that topic. It's just about displaying files in a treeview. What is "a specified UI file"? What does your title "load uic file" mean?

I have created a complex window with qt designer with a treeview. This is saved as a UI file. Now i would like to know how i can integrate this file into the code from the other topic.

Sorry, wrong comment was linked. I corrected the link above now.

@MaMo
From your .ui file you either generate a .py file from it or you dynamically load it at runtime (https://doc.qt.io/qtforpython-6/tutorials/basictutorial/uifiles.html). Either way you end up with a QTreeView or a class derived from it. You then call treeView.setModel(theFileSystemModel) at runtime to connect the view to the model (https://doc.qt.io/qtforpython-5/PySide2/QtWidgets/QTreeView.html#detailed-description).

I have always integrated the ui as follows:

from PyQt5 import QtWidgets, QtCore, uic


class ListMovies(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()

        uic.loadUi("GUI\GUI_Movies.ui", self)

        self.readAllMoviesButton.clicked.connect(self.on_read_all_entry)
        self.readMainMoviesButton.clicked.connect(self.on_read_main_entry)
        self.updateListButton.clicked.connect(self.on_update_list)
        self.addListButton.clicked.connect(self.on_add_list)
        self.newEntryButton.clicked.connect(self.on_new_entry)
        self.saveCsvButton.clicked.connect(self.on_save_csv)
        self.saveXlsButton.clicked.connect(self.on_save_xls)

        # self.actionSave.triggered.connect(self.on_save)

        self.moviesTable.itemDoubleClicked.connect(self.OpenLink)

        self.progressBar.hide()

        ui_width = self.width()
        ui_height = self.height()

        # self.setFixedWidth(ui_width)
        # self.setFixedHeight(ui_height)

        xy = fc.center_window(self, ui_width, ui_height)
        self.move(int(xy[0]), int(xy[1]))

        self.show()

Can someone please tell me how to insert it exactly into the code linked above?
Maybe someone can even give me the right lines of code?
