PyQt5 QSpinBox - 清理文本

在本文中，我们将看到如何清理旋转框的文本，清理文本意味着删除任何数字之前的空格和零，因为我们知道 001 类似于 1，因此清理文本将从文本中删除不需要的零.

为了做到这一点，我们使用 cleanText 方法。

Syntax : spin_box.cleanText()

Argument : It takes no argument

Action Performed : It cleans the text of spin box

注意：不包括前缀、后缀或前导或尾随空格。

Implementation steps :
1. Create a main window
2. Create a spin box set its range prefix and suffix
3. Create a push button
4. Add action to the push button
5. Inside the action method call the cleanText method

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")
  
        # creating a push button
        push = QPushButton("Clean", self)
  
        # setting geometry to the push button
        push.setGeometry(100, 200, 100, 40)
  
        # adding action to the push button
        push.clicked.connect(self.push_action)
  
  
    # method called by the push button
    def push_action(self):
  
        # cleaning the text
        self.spin.cleanText()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
