        super().__init__()
        self.setWindowTitle("QProgressDialog的学习")
        self.resize(400,400)
        self.set_ui()


    def set_ui(self):
        progressDialog = QProgressDialog(self)
        #它会自动的弹出  如果在4s 内进度条已经走完了,那么它就不会弹出了



if __name__ == '__main__':
    app =QApplication(sys.argv)

    window = Window()
    window.show()

    sys.exit(app.exec_())

多个参数的构造函数:

from PyQt5.Qt import * #刚开始学习可以这样一下导入
import sys

class Window(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("QProgressDialog的学习")

        self.set_ui()


    def set_ui(self):
        # progressDialog = QProgressDialog(self)
        progressDialog = QProgressDialog("xx1","xx2",1,1000,self)


        progressDialog.setAutoClose(False)
        progressDialog.setAutoReset(False)

        # progressDialog.setMinimumDuration(0)

        progressDialog.setValue(50)  #4s 后会被显示

        for i in range(1,101):
            progressDialog.setValue(i) #4s 后不会被显示


        progressDialog.open(lambda :print("对话框被取消"))
