PyQt5 QSpinBox - 未设置语言环境

在本文中，我们将了解如何取消设置旋转框的特殊区域设置。只要没有设置特殊的语言环境，旋转框的语言环境要么是父级的语言环境，要么如果给定的旋转框是顶级小部件，那么它就有自己的默认语言环境。虽然我们也可以为旋转框设置一个特殊的自定义本地。取消设置特殊语言环境意味着自定义语言环境将被删除，默认语言环境将再次恢复。

为了做到这一点，我们使用带有旋转框对象的unsetLocale方法。

Syntax : spin_box.unsetLocale()

Argument : It takes no argument

Return : It returns None

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")
  
        # locale
        locale = QLocale()
  
        # setting locale to the spin box
        self.spin.setLocale(locale)
  
        # 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)
  
        # unset the special locale
        self.spin.unsetLocale()
  
        # getting the locale of the spin box
        value = self.spin.locale()
  
        # setting text to the label
        label.setText("Locale : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
