PyQt5 - 按下时选中的 RadioButton 指示器的背景图像
在本文中,我们将看到如何在单选按钮被按下并处于选中状态时将背景图像设置为单选按钮的指示器。默认情况下,当我们按下单选按钮时,虽然我们可以更改它,但它会显示为蓝色。背景图像仅在指示器处于选中状态以及我们按下单选按钮时才会出现在指示器上。
为了将背景图像添加到单选按钮的指示器,我们必须更改它的样式表代码。下面是样式表代码。
QRadioButton::indicator:checked:pressed
{
background-image : url(image.png);
}
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 image checked indicator when it get pressed
self.radio_button.setStyleSheet("QRadioButton::indicator:checked:pressed"
"{"
"background-image : url(image.png);"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
