PyQt5 - 将背景图像设置为可编辑的组合框

在本文中，我们将了解如何将背景图像设置为可编辑的组合框。默认情况下，组合框没有图像，尽管我们可以为其设置图像。仅当组合框处于可编辑状态时才会出现背景图像。组合框的可编辑状态是当用户将文本设置到组合框时，普通的组合框可以在 setEditable 方法的帮助下进行编辑。
为此，我们必须更改与组合框关联的样式表，下面是样式表代码

QComboBox::editable
{
background-image : url(image.png);
border :1px solid black;
}

下面是实现

Python3

# 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 check-able combo box object
        self.combo_box = QComboBox(self)
 
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 200, 80)
 
        # making combo box editable
        self.combo_box.setEditable(True)
 
        # geek list
        geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
 
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
 
        # setting style sheet of the combo box
        # adding background image to the combo box it is editable
        self.combo_box.setStyleSheet("QComboBox::editable"
                                     "{"
                                     "background-image : url(logo.png);"
                                     "border : 2px solid black;"
                                     "}")
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
window.show()
 
# start the app
sys.exit(App.exec())

输出 ：
