PyQt5 – 鼠标悬停时为 ComboBox 设置背景颜色
在本文中,我们将看到当鼠标悬停在组合框上时如何设置组合框的背景颜色。默认情况下,组合框是灰色的,尽管我们可以改变它的颜色。此背景颜色仅在鼠标悬停在组合框小部件上时出现。
为此,我们必须更改组合框的样式表代码,下面是样式表代码 -
QComboBox::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 a combo box widget
self.combo_box = QComboBox(self)
# setting geometry of combo box
self.combo_box.setGeometry(200, 150, 150, 30)
# geek list
geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
# making it editable
self.combo_box.setEditable(True)
# adding list of items to combo box
self.combo_box.addItems(geek_list)
# adding background color to the combo box when mouse hover over it
self.combo_box.setStyleSheet("QComboBox::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 :
当鼠标悬停在组合框上时,它看起来像这样
