PyQt5 – 如何为组合框设置视图

在这篇文章中，我们将看到如何为组合框设置一个视图。视图基本上可以帮助我们改变下拉项目列表的视图。为了给组合框设置视图，我们将使用setView方法。

语法： combo_box.setView(view)

参数： 它以视图为参数

返回：无

以下是实现方法

# 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 Saiyan", "Super Sayian 2", 
                                               "Super Sayian B"]
  
        # making it editable
        self.combo_box.setEditable(True)
  
        # creating a view
        view = QTreeView()
  
        # setting view to combo box
        self.combo_box.setView(view)
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
