PyQt5 QSpinBox – 如何取消设置光标

在本文中，我们将了解如何取消设置旋转框的光标，光标是一种指示器，用于在计算机显示器或其他显示设备上显示用户交互的当前位置，它将响应来自文本输入或指向的输入设备。我们使用setCursor方法为其设置新光标。

In order to do this we use unsetCursor method

Syntax : spin_box.unsetCursor()

Argument : It takes no argument

Return : It returns None

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 range to the spin box
        self.spin.setRange(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # creating a cursor
        cursor = Qt.WaitCursor
  
        # setting cursor to the spin box
        self.spin.setCursor(cursor)
  
        # un-setting the cursor new cursor
        self.spin.unsetCursor()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())

输出 ：
