PyQt5 - 将皮肤设置为不可编辑组合框的行编辑部分

在本文中，我们将看到如何将皮肤设置为不可编辑组合框的行编辑部分。行编辑是用于输入和查看项目的部分。皮肤基本上是根据行编辑大小自行调整的背景图像。

注意：当我们将行编辑对象添加到组合框时，它会使组合框可编辑，需要使其不可编辑

执行此操作的步骤：
1.创建一个组合框
2.创建一个QLineEdit对象
3.给QlineEdit对象设置皮肤
4.使行编辑不可编辑
5. 将 QLineEdit 对象添加到组合框中

句法 ：

# creating line edit object
line_edit = QLineEdit()

# setting skin to line edit object
line_edit.setStyleSheet("QLineEdit"
                        "{"
                        "border-image : url(skin.png);"
                        "}")

# making it non editable
line_edit.setReadOnly(True)

# adding line edit object to combo box
combo_box.setLineEdit(line_edit)

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)
  
        # 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)
  
        # creating line edit object
        line_edit = QLineEdit()
  
        # setting skin to line edit
        line_edit.setStyleSheet("QLineEdit"
                                "{"
                                "border-image : url(skin.png);"
                                "}")
  
        # making it non editable
        line_edit.setReadOnly(True)
  
        # adding line edit object to combo box
        self.combo_box.setLineEdit(line_edit)
  
  
# 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 ：
