PyQt5 – Check Box的setChecked()方法
setChecked方法是用来改变复选框的状态。在默认情况下,点击复选框部件后,它的状态会被改变为选中,但在setChecked方法的帮助下,我们可以不点击它而直接完成。
语法: checkbox.setChecked(True)
参数: 它以bool作为参数。
执行的动作: 它将改变复选框的状态。
下面是实现方法。
# importing libraries

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 the check-box
checkbox = QCheckBox('Check Box', self)
# setting geometry of check box
checkbox.setGeometry(200, 150, 100, 30)
# setting check box state to checked
checkbox.setChecked(True)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
