PyQt5 – 复选框中未被选中的指标的背景颜色
在这篇文章中,我们将看到如何在复选框的指标处于未选中状态时设置背景色。当选中时,它将恢复到默认的形式,对于未选中的状态,我们可以设置背景色。
为了给未选中状态的指示器添加背景色,我们必须改变未选中状态的指示器的样式表,下面是样式表代码。
QCheckBox::indicator:unchecked
{
background-color : yellow;
}
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 for unchecked state
checkbox.setStyleSheet("QCheckBox::indicator:unchecked"
"{"
"background-color : yellow;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
