    Re: Accelerometer and other sensors on Belle

    And by not working QtMobility examples, I mean Sensors API examples. Other QtMobility stuff I am using, seems to work fine.

    Re: Accelerometer and other sensors on Belle

    It seems that some of the sensors are not supported on Symbian Belle when used through QtMoblity Sensors API. Or am I just doing something wrong? I am testing on Nokia 700.

    So... I was porting...

    Re: Virtual keyboard and password echo

    Ok. Found the issue. Problem arises when password field is child of a top-level widget that is wrapped by QGraphicsProxyWidget. If I wrap just password field with QGraphicsWidgetProxy it works.

    Re: connect problem

    To "stop connection" between signal and slot, there is disconnect.

    In your case, code might look like this:


    QObject::disconnect( ui->LineEdit, SIGNAL(selectionChanged()), this, SLOT(done()) );

    Re: Simple widget app getting segmentation fault..

    Thanks a lot! This narrows problem strictly to device side, which was excepted.

    And yes. I tried running it manually. Same error.

    Could it be that reflashing didn't wipe out everything?...

    Re: Simple widget app getting segmentation fault..

    That may be the case, but it might be some other libraries than Qt ones that are messing things up. Or it could be a bug in messaging that only happens in certain cases. For example I have quite a...

    Re: Simple widget app getting segmentation fault..

    Yeah. I don't think problem is with the code or with Nokia Qt SDK. Problem must be in the libraries installed to device.
