PyQt5 – 单选按钮被按下时的背景颜色
在这篇文章中,我们将看到如何为处于选中状态并被按下的单选按钮的指标设置背景色。虽然我们可以改变这个颜色,但默认情况下,指标的颜色是偏蓝的。
为了在单选按钮处于选中状态并被按下时给其添加背景色,我们必须改变样式表代码。下面是样式表的代码。
QRadiobutton::indicator:checked:pressed
{
background-color : lightgreen;
}
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
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 checked indicator when it get pressed
self.radio_button.setStyleSheet("QRadioButton::indicator:checked: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())
