Code Sample

import os
from PyQt5.QtWidgets import QMainWindow, QPushButton, QApplication
from pyqt_detailed_progress_dialog import DetailedProgressDialog


class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.__initUi()

    def __initUi(self):
        downloadStartBtn = QPushButton('Start the download')
        downloadStartBtn.clicked.connect(self.__download)
        self.setCentralWidget(downloadStartBtn)

    def getAllFilesInPath(self, pathname):
        path_lst = []
        for path, dir, files in os.walk(pathname):
            for filename in files:
                path_filename = os.path.join(path, filename)
                path_lst.append(path_filename)
        return path_lst

    def __download(self):
        filenames = self.getAllFilesInPath(os.path.join(os.path.dirname(__file__), 'src')) # Get all the filenames list in certain directory
        self.__dialog = DetailedProgressDialog(filenames)
        self.__dialog.canceled.connect(self.cancel)
        self.__dialog.completed.connect(self.complete)

    def cancel(self):
        print('cancel')

    def complete(self):
        print('complete')


if __name__ == "__main__":
    import sys

    app = QApplication(sys.argv)
    mainWindow = MainWindow()
    mainWindow.show()
    sys.exit(app.exec_())

Result

example.mp4

This video is incomplete. It should've shown the progression completely, from 0% to 100%. But it failed. I can tell you why.

First, i can't help but start in the middle of progress. Because i don't know how to start the record the video immediately when i run certain script.

Second, when i clicked the hide button to hide the QListWidget, it make the video stop somehow. I don't know why that happened.

Sorry for that.
