PyQt5 – 为复选框中的复选指标设置背景色
在这篇文章中,我们将看到如何在指标处于选中状态时为其设置背景色,当它被取消选中时,颜色将变为默认。
为了给指示器设置背景色,我们必须编辑与复选框对象一起使用的样式表,在该样式表中我们必须改变选中指示器的背景色。下面是样式表的代码。
QCheckBox::indicator:checked
{
background-color : red;
}
Python
以下是实施情况。
# 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())
