PyQt and i18n, only "half of it" is translated

[NebuK]

Hi,

i wrote a project in pyqt and wanted to let it do i18n now. so i wrapped all my texts in self.tr() and wrote a .pro file like this:

SOURCES = main.py models.py
FORMS = ui/beans.ui ui/blends.ui ui/edit.ui ui/mainWindow.ui ui/profile.ui ui/roast.ui ui/select.ui ui/settings.ui ui/temptime.ui
TRANSLATIONS = roasterbase_de.ts

SOURCES = main.py models.py
FORMS = ui/beans.ui ui/blends.ui ui/edit.ui ui/mainWindow.ui ui/profile.ui ui/roast.ui ui/select.ui ui/settings.ui ui/temptime.ui
TRANSLATIONS = roasterbase_de.ts

To copy to clipboard, switch view to plain text mode 

then i did a pylupdate4 on that pro-file and translated everything in linguist. ran lrelease on the pro file and it says that ~140 finished entries are there. now i installed a translator onto my QApplication:

app = QtGui.QApplication(sys.argv)
 
    translator = QTranslator()
    print translator.load("roasterbase_de.qm", ".")
 
    app.installTranslator(translator)

app = QtGui.QApplication(sys.argv)
    
    translator = QTranslator()
    print translator.load("roasterbase_de.qm", ".")
    
    app.installTranslator(translator)

To copy to clipboard, switch view to plain text mode 

load() returns true. Thing is, only half of the stuff is translated, only a few dialogs but not all and some table headings - but again not all...

where could i start looking for the error?

Thanks in advance

PS: the project is available on svn://ghostdub.de/roasterbase

Do these untranslated strings come from your code or are part of Qt?

[NebuK]

Partially from my code an partially from the pyuic4 converted qt-designer files...

[jacek]

Check if you don't have more than one roasterbase_de.qm file, delete all of them and run lrelease once more.

Could post the location in your code where such untranslated string appears?

[NebuK]

Example would be all strings from beans.py (created from ui/beans.ui).

Just deleted the .qm and retranslated everything, still the same :/.

thanks for the help so far!

Please post the example code, not the repository address.

Hi,

i somehow resisted to post two such long files ... also the BBS didnt allow me to post them, so i nopasted them. How i install the QTranslator is in my first post. Here the files, ui and pyuic4 generated:
http://rafb.net/p/HfZ0sF93.html
http://rafb.net/p/9fI0ir88.html

[wysota]

Couldn't you have just pasted the parts of the files that are relevant to the problem?

BTW. I don't think that ui files or autogenerated files will get us anywhere... We can assume they are ok.

[NebuK]

Well, what code should i post then? Its mainly the Strings from the pyuic generated files.

Another example would be main.py 365,

self.fcMarker1 = Qwt.QwtPlotMarker()
[...]
label = self.fcMarker1.label()
label.setText(self.tr('first Crack'))

self.fcMarker1 = Qwt.QwtPlotMarker()
[...]
label = self.fcMarker1.label()
label.setText(self.tr('first Crack'))

To copy to clipboard, switch view to plain text mode 

where the last line is 365. 'first Crack' is transted to "Erstes Knacken" in linguist, howver "first Crack" still shows up. On the other hand all headers in models.py are translated:

def headerData(self, section, orientation, role):
        if role==0 and orientation==1:
            if section==0:
                return QtCore.QVariant(self.tr("Name"))
            elif section==1:
                return QtCore.QVariant(self.tr("Country"))
            elif section==2:
                return QtCore.QVariant(self.tr("Stock"))
        return QtCore.QVariant()

def headerData(self, section, orientation, role):
        if role==0 and orientation==1:
            if section==0:
                return QtCore.QVariant(self.tr("Name"))
            elif section==1:
                return QtCore.QVariant(self.tr("Country"))
            elif section==2:
                return QtCore.QVariant(self.tr("Stock"))
        return QtCore.QVariant()

To copy to clipboard, switch view to plain text mode 

ALL strings from uic-generated files aren't translated except temptime.[py,ui] - if i only knew whats different with this one...

thanks again so far :P

[wysota]

Check if the .ts files contain correct translations and if the strings are marked as translated.

[NebuK]

Everything alright on that side - or at least it looks to me like it is. I nopasted the .ts file, so maybe someone could doublecheck: http://rafb.net/p/wHxClu46.txt

Thanks once again :P

[jacek]

What happens if you change one of the working translations and regenerate the .qm file? Can you see the change in your application?

[wysota]

I nopasted the .ts file, so maybe someone could doublecheck

And why not use the attachment feature from this forum?

[NebuK]

Heho,

just tried, changes are visible...

[jacek]

What happens if you change labels for downButton and upButton in beans.ui to "down" and "up" (or similar)?

[NebuK]

Hi,

also no luck with that, those unicode-chars dont seem to do any harm.

Try deleting all intermediate files (.pyc included) and rebuild the project.

[NebuK]

i do that everytime i try ...

i also tried again with using both, the uic generated files in SOURCES= and the .ui files in FORMS=. Another thing i tried is letting the classes generated by pyuic4 be inherited from QObject and using self.tr instead of the QtGui.QApplication.translate provided by pyuic ... doesnt work too :/.

[wysota]

Could you see if the problem is persistent across applications? I mean if the same happens for a clean simple and small application written from scratch.

[NebuK]

Just created a mainwindow with only 2 labels, one set from the source, and one set from the ui file. i then again tried both, including the .ui or the uic4-generated .py in the .pro and translating. Didnt work - only the label i set from source worked, ui didnt.
