PyQt5 – 如何获得组合框的视图

在这篇文章中，我们将看到如何获得组合框的视图。视图基本上可以帮助我们改变下拉项目列表的视图。为了设置组合框的视图，我们将使用setView方法。为了获得视图，我们使用view方法。

语法： combo_box.view()

参数： 它不需要参数

返回： 它将返回视图类型对象

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)
 
        # getting view
        get_view = self.combo_box.view()
 
        # creating label to show 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())
