PyQt5 – 不可编辑组合框的 lineedit 部分的边框宽度不同

在本文中，我们将看到如何为不可编辑组合框的行编辑部分设置不同的边框宽度，行编辑是组合框显示所选项目的部分，它本质上是可编辑的。为了设置和访问行编辑对象，我们分别使用setLineEdit和 lineEdit 方法。

In order to do this we have to do the following :

1. Create a combo box
2. Add item to the combo box
3. Create a QLineEdit object
4. Set border with different width to the QLineEdit object
5. Make line edit object non-editable(read-only)
6. Add QLineEdit object to the combo box

编程需要懂一点英语

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, 150, 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 border to the line edit part
        # set different border width
        line_edit.setStyleSheet("QLineEdit"
                                "{"
                                "border : solid black;"
                                "border-width : 1px 10px 2px 5px;"
                                "}")
  
        # making line edit read only
        line_edit.setReadOnly(True)
  
        # adding line edit object to the combo box
        self.combo_box.setLineEdit(line_edit)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
