PyQt5 – 当鼠标悬停在未选中的单选按钮上时,将背景图片设置为单选按钮的指示灯
在这篇文章中,我们将看到当鼠标悬停在单选按钮上,并且它处于未选中状态时,我们如何为其设置背景图片。默认情况下,虽然我们可以为它添加图像,但没有图像与之相关。背景图像只在它处于未选中状态和鼠标悬停在单选按钮上时出现在指标上。
为了给单选按钮的指示器添加背景图像,我们必须改变它的样式表代码。下面是样式表的代码。
QRadioButton::indicator:unchecked:hover
{
background-image : url(image.png);
}
Python
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 image unchecked indicator when mouse hover over it
self.radio_button.setStyleSheet("QRadioButton::indicator:unchecked:hover"
"{"
"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())
