PyQt5 - 按下时如何更改复选框背景颜色
在本文中,我们将了解如何在按下复选框时为其设置背景颜色。默认情况下,没有与之关联的背景颜色。此背景颜色只会出现复选框被按下。
为了给复选框添加背景颜色,我们必须更改样式表代码,下面是执行此操作的样式表代码。
QCheckBox::pressed
{
background-color : lightgreen;
}
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, 600, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating the check-box
checkbox1 = QCheckBox('Geek ?', self)
# setting geometry of check box
checkbox1.setGeometry(200, 150, 100, 40)
# changing style sheet code of check box
# adding background color to check box when it get pressed
checkbox1.setStyleSheet("QCheckBox::pressed"
"{"
"background-color : lightgreen;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
