PyQt5 QSpinBox – 获取文本的翻译版本

在本文中，我们将了解如何获得文本的翻译版本。文本的翻译版本基于消歧字符串和包含复数的字符串的 n 值。如果没有合适的翻译字符串可用，翻译文本将是 UTF-8字符串，即 Unicode 编解码器，并且可以表示 Unicode字符串中的所有字符，如 QString。但是，UTF-8 可能会出现无效序列，如果发现任何此类，它们将被替换为一个或多个“替换字符”，或被抑制。

为了做到这一点，我们使用带有旋转框对象的tr方法。

Syntax : spin_box.tr(text, d_text, n)

Argument : It takes 3 arguments first one is the text and other two are not compulsory first is disambiguation string and other is the integer that refer to the plurals number

Return : It returns string

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(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
  
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
  
        # setting status tip to the spin box
        self.spin.setStatusTip("Small Value")
  
        # creating a label
        self.label = QLabel(self)
  
        # making label multi line
        self.label.setWordWrap(True)
  
        # setting label geometry
        self.label.setGeometry(100, 200, 250, 60)
  
        # translating the text
        value = self.spin.tr(self.spin.text())
  
        # setting text to the label
        self.label.setText("Translated text : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
