PyQt5 – 为单选按钮的指示器设置颜色
在本文中,我们将了解如何为单选按钮的指示器设置颜色。默认情况下,白色与指示器相关联,尽管我们可以借助与其相关联的指示器样式表来更改颜色。
为了改变指示器的颜色,我们在样式表中为指示器设置了背景颜色。下面是执行此操作的样式表代码。
QRadioButton
{
background-color : lightgreen;
}
注意:当我们更改与指标关联的样式表代码时,指标的形状会设置为正方形。
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 color to the indicator
radio_button.setStyleSheet("QRadioButton::indicator"
"{"
"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())
