PyQt5 QSpinBox - 检查它是否加速

在本文中，我们将了解如何检查旋转框是否加速。加速旋转框意味着在按下步进向上/向下按钮时加快步进频率。如果旋转框设置为加速，则按住按钮的时间越长，它会更快地增加/减少值。尽管我们可以使用setAccelerated方法使旋转框加速，但默认情况下旋转框不加速。

为了做到这一点，我们使用带有旋转框对象的isAccelerated方法。

Syntax : spin_box.isAccelerated()

Argument : It takes no argument

Return : It returns bool

编程需要懂一点英语

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(1, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
  
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
  
        # making spin box accelerate
        self.spin.setAccelerated(True)
  
        # creating a label
        label = QLabel(self)
  
        # making the label multi line
        label.setWordWrap(True)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 60)
  
        # checking if spin box is accelerated
        check = self.spin.isAccelerated()
  
        # setting text to the label
        label.setText("Accelerated ? : " + 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：
