PyQt5 QListWidget – 获取编辑触发器属性

在本文中，我们将了解如何获取 QListWidget 的编辑触发器属性。 QListWidget 是一个方便的类，它提供了一个带有经典的基于项目的界面的列表视图，用于添加和删除项目。 QListWidget 使用内部模型来管理列表中的每个 QListWidgetItem。此属性描述将启动项目编辑的操作，它可以在setEditTriggers方法的帮助下设置。

In order to do this we will use editTriggers method with the list widget object.

Syntax : list_widget.editTriggers()

Argument : It takes no argument

Return : It returns edit triggers object

编程需要懂一点英语

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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
  
  
    # method for components
    def UiComponents(self):
  
        # creating a QListWidget
        list_widget = QListWidget(self)
  
        # setting geometry to it
        list_widget.setGeometry(50, 70, 150, 60)
  
        # list widget items
        item1 = QListWidgetItem("A")
        item2 = QListWidgetItem("B")
        item3 = QListWidgetItem("C")
  
        # adding items to the list widget
        list_widget.addItem(item1)
        list_widget.addItem(item2)
        list_widget.addItem(item3)
  
        # setting edit trigger property
        list_widget.setEditTriggers(QAbstractItemView.NoEditTriggers)
  
        # creating a label
        label = QLabel("GeesforGeeks", self)
  
        # setting geometry to the label
        label.setGeometry(230, 80, 280, 80)
  
        # making label multi line
        label.setWordWrap(True)
  
        # getting edit triggers property
        value = list_widget.editTriggers()
  
  
        # setting text to the label
        label.setText("Edit Trigger : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
