PyQt5 - 为 ComboBox 的 lineedit 部分添加边框

在本文中,我们将看到如何为组合框的行编辑部分设置边框。行编辑部分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setLineEditlineEdit方法。下面是普通组合框与行编辑部分有边框的组合框的表示。

句法 :

# creating line edit object
line_edit = QLineEdit()

# setting border to the line edit
line_edit.setStyleSheet("QLineEdit"
                        "{"
                        "border : 2px solid green;"
                        "}")

# adding line edit object to the combo box
self.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 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"]
  
        # 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
        line_edit.setStyleSheet("QLineEdit"
                                "{"
                                "border : 2px solid green;"
                                "}")
  
        # 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 :
