PyQt5 QSpinbox - 检查是否启用了接受丢弃

在本文中，我们将看到如何检查是否启用了在旋转框中的 drop 的接受，我们使用setAcceptDrops方法来启用接受 drop。为了检查旋转框的接受放置属性是否启用，我们使用acceptDrops方法。

为了做到这一点，我们使用带有旋转框的 acceptDrops 方法。

Syntax : line_edit.acceptDrops()

Argument : It takes no argument

Return: It returns bool

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 spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # making accept drop enabled
        self.spin.setAcceptDrops(True)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 30)
  
        # checking if accept drop is enabled
        check = self.spin.acceptDrops()
  
        # setting text to the label
        label.setText("Accept drop enabled ? : " + str(check))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
