PyQt5 - 如何获得组合框的视图

在本文中，我们将了解如何查看组合框。 View 基本上帮助我们改变下拉项目列表的视图。为了将视图设置为组合框，我们将使用setView方法。为了获得视图，我们使用view方法。

Syntax : combo_box.view()

Argument : It takes no argument

Return : It will return view type object

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 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)
  
        # getting view
        get_view = self.combo_box.view()
  
        # creating label to dhow the view object
        label = QLabel("view = " + str(get_view), self)
  
        # setting geometry of the label
        label.setGeometry(150, 100, 300, 30)
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
