PyQt5 – 为单选按钮的指示器设置颜色
在这篇文章中,我们将看到如何为单选按钮的指示灯设置颜色。默认情况下,指标是白色的,尽管我们可以在与之相关的指标样式表的帮助下改变其颜色。
为了改变指示器的颜色,我们已经在样式表中为指示器设置了背景色。下面是样式表的代码,可以做到这一点。
QRadioButton
{
background-color : lightgreen;
}
Python
注意: 当我们改变与指标相关的样式表代码时,指标的形状被设置为方形。
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 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())
Python
