PyQt5 QSpinBox – 获取线程

在本文中，我们将了解如何获取旋转框的线程。旋转线是旋转框所在的线。一个接口可以有多个线程，从而提高性能。

为了做到这一点，我们使用带有旋转框对象的thread方法。

Syntax : spin_box.thread()

Argument : It takes no argument

Return : It returns QThread object

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")
  
        # setting status tip to the spin box
        self.spin.setStatusTip("Small Value")
  
        # creating a label
        self.label = QLabel(self)
  
        # making label multi line
        self.label.setWordWrap(True)
  
        # setting label geometry
        self.label.setGeometry(100, 200, 250, 60)
  
        # getting the thread
        value = self.spin.thread()
  
        # setting text to the label
        self.label.setText("Thread  : " + 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 ：
