PyQt5 QSpinBox - 访问单步大小

在本文中，我们将了解如何访问微调框的单步长，默认情况下，当我们创建微调框时，步长为 1。步长基本上是增量或减量大小。为了设置步长，我们使用setSingleStep方法。

为此，我们将使用singleStep方法。

Syntax : spin_box.singleStep()

Argument : It takes no argument

Return : It returns integer

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 single step size
        self.spin.setSingleStep(5)
  
        # creating label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 160, 200, 30)
  
        # getting single step size
        step = self.spin.singleStep()
  
        # setting text to the label
        label.setText("Step Size : " + str(step))
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
