PyQt5:强制翻译特定语言

Question

无论在应用程序中选择了哪种语言，我都在尝试翻译成特定语言。 我试图不更改应用程序的语言，所以即使知道我所在的应用程序，我认为也不会帮助我。 下面我有一个 alwaysTranslate(( 方法，即使我在应用程序中卸载翻译器(或者在这种情况下我只是没有翻译器(，我也总是想返回翻译的文本。

import sys
from os import getcwd
from PyQt5.QtWidgets import QApplication
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Form(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(556, 362)
        self.verticalLayout = QtWidgets.QVBoxLayout(Form)
        self.verticalLayout.setObjectName("verticalLayout")
        self.lineEdit = QtWidgets.QLineEdit(Form)
        self.label = QtWidgets.QLabel()
        self.verticalLayout.addWidget(self.label)
        self.lineEdit.setObjectName("lineEdit")
        self.verticalLayout.addWidget(self.lineEdit)
        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)
    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        self.label.setText(_translate("Ui_Form", "something"))
    # this is what I want to come back with a local translation
    def alwaysTranslate(self):
        qt_translator = QtCore.QTranslator()
        m_langPath = getcwd()
        qt_translator.load("test.qm", m_langPath)
        _translate = QtCore.QCoreApplication.translate
        print("should NOT be 'something': " + _translate("Ui_Form", "something"))
if __name__ == '__main__':
    app = QApplication(sys.argv)
    qt_translator = QtCore.QTranslator(app)
    m_langPath = getcwd()
    _translate = QtCore.QCoreApplication.translate
    qt_translator.load("test.qm", m_langPath)
    app.installTranslator(qt_translator)
    print("should NOT be 'something': " + _translate("Ui_Form", "something"))
    qt_translator.load("en.qm", m_langPath)
    app.installTranslator(qt_translator)
    print("should be 'something': " + _translate("Ui_Form", "something"))
    ex =  Ui_Form()
    ex.alwaysTranslate()
    sys.exit(app.exec_())

我我的测试.ts文件看起来

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS><TS version="2.0" language="zh_TW" sourcelanguage="en_US">
<context>
    <name>Ui_Form</name>
    <message>
        <location filename="test.py" line="58"/>
        <source>something</source>
        <translation>matters not</translation>
    </message>
</context>
</TS>

当我运行它时，我得到以下内容

不应该是"某物"：不
重要 应该是"某物"：某物
不应该是"某物"：某物

最后一个我也想成为"不重要"。

Answer 1

我没有

尝试过，但我认为这应该有效：

def alwaysTranslate(self):
    qt_translator = QtCore.QTranslator()
    m_langPath = getcwd()
    qt_translator.load("test.qm", m_langPath)
    # use local translator
    _translate = qt_translator.translate
    print("should NOT be 'something': " + _translate("Ui_Form", "something"))
