PyQt5 QSpinBox - 设置单步大小

在本文中，我们将看到如何设置微调框的单步长，默认情况下，当我们创建微调框时，步长为 1。步长基本上是递增或递减的大小。

为此，我们将使用setSingleStep方法。

Syntax : spin_box.setSingleStep(step)

Argument : It takes integer as argument

Return : 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 single step size
        self.spin.setSingleStep(5)
  
          
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
