PyQt5 – 按下单选按钮时将背景颜色设置为单选按钮的指示器
在本文中,我们将看到如何在单选按钮被按下时将背景颜色设置为指示符,默认情况下,当我们按下单选按钮时会关联蓝色,尽管我们可以更改此颜色。
为了改变指示器被按下时的背景颜色,我们必须改变单选按钮的样式表代码,下面是样式表代码。
QRadioButton::indicator:pressed
{
background-color : light green;
}
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 a radio button
self.radio_button = QRadioButton(self)
# setting geometry of radio button
self.radio_button.setGeometry(200, 150, 120, 40)
# setting text to radio button
self.radio_button.setText("Radio Button")
# changing style sheet code of radio button
# setting background color to indicator when it get pressed
self.radio_button.setStyleSheet("QRadioButton::indicator: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 :
