That's actually a QWidget method, so I don't know if the problem happens only with line edits ("object has no method called...").
If I comment out those lines in the UI files, the rest of the code runs fine -- not pretty, but working :-)
Has this method been added since Qt 4.5.3 ?

Oh, and a third one : is there a Maemo4 API somewhere to make less ugly apps with PyQt ?... :-)

Qt4.6 port has been a rewrite (the port, not Qt), so most of the Maemo specifics - esp regarding input methods end events - are done differently, which has all sorts of implications. Q4.5 was more of a tech demonstrator, to show Qt could actually run, and also a lot of the Hildon finger/look goodies came later so there was a lot less to 'build on' at the time of 4.5. This is also the reason why, real, good lookin' 4.6 or 4.7 on N8x0 is not a trivial thing - it relies quite a bit on Fremantle parts to actually look/behave as it does - and those are simply not present on Diablo.
Not sure I follow - is the problem that you are compiling with the 4.7.5 pyuic ? Does it happen if you use the corresponding 4.7.1 Diablo pyuic, too ?
I just tend to copy the whole lot over and see what happens. So yes, the UI files were done with the newer pyuic. I'll give it a try, just for kicks...

OK, reality check report... What I did :
On the N810,
- deleted the offending Ui_xxxx.py
- used the pyuic4.py from the PyQt 4.7.1 snapshot on the original xxxx.ui file (the one made with the Qt 4.6.2 Designer, with the inputHints in the XML)
- generated a new Ui_xxxx.py
The inputHints for the line edit are back in the Python code. So it seems commenting them out after the fact is the only workaround.
Is that what you wanted to verify ?

Hm, it seems that pyuic is not too smart then (i.e. it doesn't really know/do anything about what version of Qt it was originally built with). In that case, not much help - a newer PyQt would probably make the same mistake, as it would happily translate the 4.6.2 design into non-4.5 compatible ui_...py files.

Yup. Well, at least the manual fix is easy :-)

My wording was bad. I guess I wasn't so much thinking of a *Qt* Maemo4 API, like Fremantle has... but more like coding hacks or good practice that could make a Qt4.5 app feel more at home in Diablo, and not stand out so much as a ported desktop app.
Are there any examples of PyQt apps tweaked specifically for use on a N8x0 out there ?
