PyQt5 – 设置组合框模型中的可见列

在这篇文章中，我们将看到如何设置组合框的可见列。这是用来设置用户可见的那一列，模型列属性持有模型中可见的那一列。为了设置这个，我们使用setModelColumn方法。

语法： combo_box.setModelColumn(n)

参数： 它需要整数作为参数，即列索引。

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)
  
        # setting visible model column 
        self.combo_box.setModelColumn(0)
          
        # geek list
        geek_list = ["Sayian", "Super Saiyan", "Super Sayian 2", "Super Sayian B"]
  
        # making it editable
        self.combo_box.setEditable(True)
  
        # 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())

输出 :
