PyQt5 QCommandLinkButton – 下载属性
在本文中,我们将了解如何获取 QCommandLinkButton 的属性。 Down 属性保存命令链接按钮是否被按下。如果此属性为 true,则按下按钮。如果我们将此属性设置为 true,则不会发出pressed
和clicked
的信号。默认情况下,此属性为 false。我们可以在setDown
方法的帮助下设置这个属性。
为了做到这一点,我们使用isDown
方法和命令链接按钮对象
Syntax : button.isDown()
Argument : It takes no argument
Return : It return bool
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, 200, 50)
# setting down property
cl_button.setDown(True)
# creating label
label = QLabel("GeeksforGeeks", self)
# setting label geometry
label.setGeometry(50, 100, 200, 40)
# getting down property
value = cl_button.isDown()
# setting text to the label
label.setText("Down : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
