PyQt5 QSpinBox – 设置对象名称

在本文中，我们将看到如何设置旋转框的对象名称，对象名称基本上是赋予旋转框对象的名称，当我们在 PyQt5 应用程序中借助对象名称借助findChild方法。

为了做到这一点，我们将使用setObjectName方法..

Syntax : spin_box.setObjectName(name)

Argument : It takes string as 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, 150, 40)
  
        # setting suffix to spin
        self.spin.setSuffix(" Spin Box")
  
        # name
        name = "Geeky"
  
        # setting up object name
        self.spin.setObjectName(name)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
