Description

Summary is in a subject line. More detailed example:

main.py - very simle file to display main window and assign text to a label:

from PySide6.QtWidgets import QApplication, QMainWindow
from main_wnd import Ui_MainWindow

class MainWnd(QMainWindow, Ui_MainWindow):
    def __init__(self):
        QMainWindow.__init__(self)
        self.setupUi(self)

        self.label.setText(self.tr("Test label"))


def main():
    app = QApplication()
    wnd = MainWnd()
    wnd.show()
    return app.exec()


if __name__ == '__main__':
    main()

UI of main window is created as main_wnd.ui with help of Qt Designer (attached). This file was converted to main_wnd.py with help of command /usr/lib/qt6/uic -g python -o ./main_wnd.py ./main_wnd.ui. It contains a right block of code for UI translation:

def retranslateUi(self, MainWindow):
    MainWindow.setWindowTitle(QCoreApplication.translate("MainWindow", u"Test phrase window", None))
    self.label.setText(QCoreApplication.translate("MainWindow", u"TextLabel", None))

Then I created very simple main.pro file:

SOURCES = ./main.py ./main_wnd.py
TRANSLATIONS = en.ts ru.ts

Next step is to generate translation files and here is the problem.

When I run command /usr/lib/qt6/bin/lupdate main.pro I get only this in ru.ts:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS>
<TS version="2.1">
<context>
    <name>MainWnd</name>
    <message>
        <location filename="main.py" line="12"/>
        <source>Test label</source>
        <translation type="unfinished"></translation>
    </message>
</context>
</TS>

I.e. it takes only text from my own main.py module and ignores QCoreApplication.translate() calls generated by Qt Designer in main_wnd.py.

Old version of the tool (pylupdate5 main.pro) generates full set of tranlations - one line for main.py and two lines for main_wnd.py:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS>
<TS version="2.1">
<context>
    <name>MainWindow</name>
    <message>
        <location filename="main_wnd.py" line="50"/>
        <source>Test phrase window</source>
        <translation type="unfinished"></translation>
    </message>
    <message>
        <location filename="main_wnd.py" line="51"/>
        <source>TextLabel</source>
        <translation type="unfinished"></translation>
    </message>
</context>
<context>
    <name>MainWnd</name>
    <message>
        <location filename="main.py" line="9"/>
        <source>Test label</source>
        <translation type="unfinished"></translation>
    </message>
</context>
</TS>
