PyQt5 - 如何在组合框模型中获取可见列

在本文中，我们将看到如何获得组合框的可见列。列模型用于设置对用户可见的列，模型列属性保存模型中可见的列。为了设置它，我们使用setModelColumn方法。为了获得模型列，我们使用modelColumn方法。

Syntax : combo_box.modelColumn()

Argument : It takes no argument

Return : It returns integer

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)
  
        # 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)
  
        # getting model column
        model_column = self.combo_box.modelColumn()
  
        # creating label to show model
        label = QLabel("Model Column = " + str(model_column), self)
  
        # setting geometry to the label
        label.setGeometry(200, 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：
