PyQt5 – 进度条的 maximum() 方法
PyQt5 中的进度条允许我们设置进度条的取值范围。 maximum
方法用于获取进度条的最大值,即范围的上限。此方法返回整数值,如果我们不设置范围,默认为 100。
Syntax : bar.maximum()
Argument : It takes no argument
Return : It returns integer.
代码 :
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
# setting title
self.setWindowTitle("Python ")
# setting geometry
self.setGeometry(100, 100, 600, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating progress bar
bar = QProgressBar(self)
# setting geometry to progress bar
bar.setGeometry(200, 150, 200, 30)
# setting maximum value of progress bar to 200
bar.setMaximum(200)
# setting value to progress bar
bar.setValue(100)
# getting maximum value of progress bar
value = bar.maximum()
# creating label to print the value
label = QLabel("maximum value = " + str(value), self)
# adjusting the size of label
label.adjustSize()
# moving the label
label.move(200, 200)
# setting alignment to centre
bar.setAlignment(Qt.AlignCenter)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
