PyQt5 – 如何更改单选按钮中的指示器边框
在本文中,我们将了解如何更改单选按钮的边框。默认情况下,指示器是圆形的,并且有黑色边框,尽管我们可以更改边框的大小和颜色。
为了改变指示器的边框,我们必须改变与单选按钮相关的指示器的样式表。下面是样式表代码。
QRadioButton::indicator
{
border : 2px solid green;
}
注意:当我们更改指示器的样式表时,它的形状会从圆形变为方形。
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
radio_button = QRadioButton(self)
# setting geometry of radio button
radio_button.setGeometry(200, 150, 120, 40)
# setting text to radio button
radio_button.setText("Radio Button")
# setting style sheet associated with the radio button
# adding border to the indicator
radio_button.setStyleSheet("QRadioButton::indicator"
"{"
"border : 2px solid green"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
