PyQt5 QSpinbox - 检查是否启用了拖动

在本文中,我们将看到如何检查是否为整个文本(即包括前缀和后缀)启用了拖动。当我们创建一个旋转框时,我们不能从中拖动文本,拖动文本意味着根据光标将选定的文本移动到任何位置,我们使用setDragEnabled方法和旋转框的行编辑对象来启用拖动。

为此,我们将 dragEnabled 方法与旋转框的行编辑对象一起使用。

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")
  
        # getting the line edit object
        line = self.spin.lineEdit()
  
        # enabling the drag
        line.setDragEnabled(True)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 30)
  
        # checking if drag is enabled
        check = line.dragEnabled()
  
        # setting text to the label
        label.setText("Drag 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 :
