PyQt5 QSpinBox - 访问显示整数基数

在本文中，我们将了解如何获得旋转框的显示整数基数，基数或基数是计数系统用来表示数字的不同数字的数量或数字和字母的组合。默认整数基数为 10，尽管我们可以更改它。

为此，我们将使用spin_box.displayIntegerBase方法。

Syntax : spin_box.displayIntegerBase()

Argument : It takes no argument

Return : It returns integer i.e its base

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, 100, 40)
  
        # setting display integer base
        self.spin.setDisplayIntegerBase(2)
  
        # creating label show result
        self.label = QLabel(self)
  
        # setting geometry
        self.label.setGeometry(100, 200, 200, 40)
  
        # getting display integer base
        base = self.spin.displayIntegerBase()
  
        # setting text to the label
        self.label.setText("Base : " + str(base))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())

输出 ：
