[PyQt] QTabWidget subclassing woes
Hi, I tried to subclass QTabWidget in order to do some processing before a tab is displayed or left. The problem is, that my setCurrentIndex methods are not called, if switching tabs via keyboard (cursor left/right on linux). Interestingly, my keyPressEvent handlers are called. Out of desperation, I also intercepted QTabBar, but beside key presses, the expected calls to setCurrentIndex are missing. I've added some shortcuts (Alt+Left/Right) to switch tabs programmatically, but I would like to catch all set* calls. Do I do something stupid, or do I need to handle the key presses myself (which would make the whole thing less robust and less portable)? TIA, Pete tabwidget.py Description: application/python ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

The problem is, that my setCurrentIndex methods are not called, if switching tabs via keyboard (cursor left/right on linux). Thats because the C++ setCurrentIndex method is not virtual and hence cannot be overriden so easily. Your only options are handling all events yourself (also check wether QTabWidget has any event filters set) or do your processing based on the currentChanged() signal instead (i.e. post-processing).

[PyQt] [i18n] Can't understand contexts
Hi,
I develop my application using PyQt4.
First I've decided to put all messages those are subject to be translated
into a separate file, let's call it msg.py like:
ADD_ACTION = QCoreApplication.translate('here goes context', 'Add', '', 1)
# ...
and etc. and init QApplication and setup translators in main source file
before import-ing msg.py.
Is it possible to put something as context argument so translations will
actually work for all classes or is there any way to disable
context chack?
P.S. Even when I put class name for class that exists in main source file
and is already declared into context arg, e. g. QtInterface
or AddAction anything doesn't get translated.
Thanks!

Context is just a string that allows you to differentiate between the
same string being used in different places of your application.
Sometimes these differing places need different translations in some
languages, hence the translator needs a context. For proper translation
appearing in the GUI there shouldn't be anything you need to do. lupdate
should extract the messages including the custom context into the .ts
file and there it'll appear for the translator to use.
P.S. Even when I put class name for class that exists in main source
file and is already declared into context arg, e. g. QtInterface
or AddAction anything doesn't get translated.
Hmm, strange, works fine here with the attached three files (C++
though). Can you post a minimal example?
(To run the example put all three files into a directory, then do qmake;
make; lrelease testtrans.pro)

I just need to test these features sooner than later, and the next Qt release is 6-9 months off. In order to get these classes, you'll have to get Qt/master or Qt/master-stable out of the git repo. Part of deleivery, aside from sip files is to then provide instructions on how to drop it into a PyQt 4.5.2 installation. Classes I need immediately for my test: ($100) * QAbstractAnimation * QAnimationGroup * QEasingCurve * QParallelAnimationGroup * QPropertyAnimation * QSequentialAnimationGroup * QVariantAnimation Not so immediate, but would like to have them eventually: ($100) * QGraphicsWidget * QAbstractState * QAbstractTransition * QActionState * QEventTransition * QFinalState * QHistoryState * QKeyEventTransition * QMouseEventTransition * QSignalEvent * QSignalTransition * QState * QStateAction * QStateFinishedEvent * QStateFinishedTransition * QStateInvokeMethodAction * QtStateMachine * QTransition I figure it's a cool opportunity to get paid for something that has to be done anyway.

[PyQt] Function-pointer typedef
Hi Phil
In my attempt to wrap the new Qt animation classes, as requested by Jason H,
I find that I'm not able declare a function-pointer typedef within a class.
According to the SIP syntax specification it seems perfectly possible,
however. Can you please tell me why the following declaration from
QEasingCurve doesn't work:
class EasingCurve
{
[...]
public:
typedef qreal (*EasingFunction)(qreal progress);
[...]
};

Thanks, you're right. Looks like I'll have to wrap the function-pointer by
hand though, am I right (sip says I have to provide %Metod code)? I'm
guessing you should fix sip's error message to say %MethodCode instead of
%Method code.

If I embed the FigureCanvas in a QTabWidget the widget is to big, but if I put it in a QWidget it is shown correctly. Sorry, but this is my first try of Matplotlib and I don't know what I could have done wrong - maybe this is just because it's nearly 3 o'clock in the night and I'm to tired to find this mistake. ;-) Thanks for help, Lukas PyQt4_MPL.tar.bz2 Description: application/bzip-compressed-tar ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
