PyQt5 QCommandLinkButton – 如何设置检查状态
在本文中,我们将了解如何使可检查的 QCommandLinkButton 被选中或取消选中,默认情况下它是不可选中的,尽管我们可以随时借助setCheckable
方法使其可选中。此外,当它是可检查的时,它的状态是未检查的,尽管我们可以以编程方式使其状态检查。
为了做到这一点,我们使用setChecked
方法和命令链接按钮对象
Syntax : button.setChecked(True)
Argument : It takes bool as argument
Return : It returns None
下面是实现
# 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, 500, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating a command link button
cl_button = QCommandLinkButton("Press", self)
# setting geometry
cl_button.setGeometry(250, 100, 150, 50)
# making it checkable
cl_button.setCheckable(True)
# making its state checked
cl_button.setChecked(True)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
