PyQt5 - 复选框中选中指示器的背景颜色
在本文中,我们将看到如何在指示器处于选中状态时为其设置背景颜色,当它被取消选中时,它的颜色将变为默认值。
为了给指示器设置背景颜色,我们必须编辑与复选框对象一起使用的样式表,并且我们必须更改选中指示器的背景颜色。下面是样式表代码。
QCheckBox::indicator:checked
{
background-color : red;
}
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
checkbox = QCheckBox('Geek ?', self)
# setting geometry of check box
checkbox.setGeometry(200, 150, 100, 30)
# adding background color to the indicator
# when it is in checked state
checkbox.setStyleSheet("QCheckBox::indicator:checked"
"{"
"background-color : red;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
