displaying several treeviews one below the other

[sof4Rou]

I have a project that consists in displaying a datamodel using qtreeview from a folder that contains several files. I displayed a treeview of a single file but i couldn't display several treeviews one under the other of several files.
here is my main.py :

import sys
from PyQt5.QtWidgets import *
from start_window import StartWindow

def main():
    app = QApplication(sys.argv)
    start_window = StartWindow()
    start_window.show()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

my start_window.py where I need to implement the choose folder function to reach the goal :

from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from table_view import Table
from odl_parser import ODLParser

class StartWindow(QDialog):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setWindowTitle('Open ODL File or Folder')
        self.resize(600, 400) 

        main_layout = QHBoxLayout(self)

        self.image_label = QLabel(self)
        self.image_label.setPixmap(QPixmap('ACLViewer.jpg').scaled(300, 300, Qt.KeepAspectRatio))
        main_layout.addWidget(self.image_label)

        buttons_layout = QVBoxLayout()

        self.choose_file_button = QPushButton('Choose File', self)
        self.choose_file_button.clicked.connect(self.choose_file)
        buttons_layout.addWidget(self.choose_file_button)
        
        self.choose_folder_button = QPushButton('Choose Folder', self)
        self.choose_folder_button.clicked.connect(self.choose_folder)
        buttons_layout.addWidget(self.choose_folder_button)

        main_layout.addLayout(buttons_layout)

    def choose_file(self):
        file_path, _ = QFileDialog.getOpenFileName(self, "Open ODL File", "", "ODL Files (*.odl)")
        if file_path:
            self.open_table_view(file_path)

    def choose_folder(self):
        folder_path = QFileDialog.getExistingDirectory(self, "Open Folder Containing ODL Files")
        if folder_path:
            # code for the folder

    def open_table_view(self, file_path):
        parser = ODLParser(file_path)
        window = Table(parser)
        window.setWindowTitle('DM Parsing - ' + file_path)
        window.show()

can anybody help me ?

@sof4Rou said in displaying several treeviews one below the other:

but i couldn't display several treeviews one under the other of several files

And what is the problem? If you can add one QTreeView then you can also add more than one.

I'm not sure, but I wonder whether @sof4Rou really means they want one treeview and have not understood that each row in the treeview is another (potentially-collapsible) node. That is what their picture looks like to me. @sof4Rou: why do you want multiple treeviews?

[sof4Rou]

@JonB I don't want one treeView , I have many files , each file has an output one treeView but now i have a folder which contain several files , so when i choose a folder i want to display all the treeview one under the other

@sof4Rou
Then, as in any case where you want to create multiple widgets at runtime, you will have to create new QTreeViews dynamically (at runtime). And have somewhere to add them onto, like a QVBoxLayout.
