I have a QT aplication, and in GUI i usses subclasses e.g.
Code in file1:

class Test(QWidget):
    def __init__():
        print(self.tr("hi! I'm test"))
        ...

Code in file2:

class TestChild(Test):
    def __init__():
        super().__init__()
        print(self.tr("hi! I'm another test"))
        ...

And translations works fine when i call Test class. But, when i call TestChild class, i get first print untranslated, and second print translated.

Both of files is in sources in .pro file
How can i get translation from super class?

Actually I find solution in adding a own translation methods to every file, but this is’nt right solution.
