PyQt5 – 在关闭状态下将皮肤设置为组合框

在本文中，我们将了解如何在组合框处于关闭状态时为其设置皮肤。关闭状态基本上是列表视图部分未打开时。皮肤是根据组合框大小自行调整的背景图像。当组合框列表视图（项目视图）部分未打开时，皮肤只会出现在组合框中。

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::!on
{
border-image : url(image.png);
}

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 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 combo box
        # adding skin to the combo box when it is in OFF state
        self.combo_box.setStyleSheet("QComboBox::! on"
                                     "{"
                                     "border-image : url(image.png);"
                                     "border : 1px 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 ：
