PyQt5 – 悬停时更改标签的背景颜色
在本文中,我们将看到当光标悬停在标签上时如何更改标签的背景颜色。当光标出现在标签上时,它会改变颜色,当光标不在标签上时,它会回到默认颜色。
为此,我们必须更改与标签对象一起使用的样式表代码,并且必须在鼠标悬停在其上时设置背景颜色,下面是样式表代码。
QLabel::hover
{
background-color : lightgreen;
}
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 label
label = QLabel("Hello Geeks", self)
# setting geometry of the label
label.setGeometry(200, 150, 100, 40)
# setting background color to label when mouse hover over it
label.setStyleSheet("QLabel::hover"
"{"
"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())
输出 :
