    QlineEdit not usable after modal dialog

    Hello,
    after starting and closing a modal Dialog i am not able to click in a QLineEdit field to change the value.

    QLineEdit* qEditName = new QLineEdit(this);

    is working fine.
    but after some interaction i show a Fullsceen Dialog:

    SpringjamTellDialog *sjDialogObject = new SpringjamTellDialog(qHashDaten.value("t" + strResStr));
    sjDialogObject->setAttribute(Qt::WA_QuitOnClose);

    sjDialogObject->exec()

    and when i come back.. the QLineEdit is somehow deactivated to edit.
    thx
    Paul

    Just out of curiosity, why are you defining that attribute (Qt::WA_QuitOnClose)?
    It *should* quit after the dialog is dismissed, but apparently it can't (either bug in Qt, or in your app). This might be the root cause for the inactive QLineEdit.

    I set this attribute (Qt::WA_QuitOnClose) because it was used in the examüley i have. and i come back to the QWidget i used before - for example the buttons are working and so on but i cannot step into the QLineEdit.
    I am using Qt 4.6 with Nokia Qt SDK 1.0
    THx paul

    If you don't need that attribute, take it away. If that doesn't help your app, it sounds like the focus is broken.

    can you tell me what do you mean when you say "the focus is broken"?
    i cannot even set the Focus using the setFocus method.
    thx paul

    Re: QlineEdit not usable after modal dialog

    It was a comment that the focus probably goes to incorrect place. And the problem might be inside Qt itself (please, raise an issue to http://bugreports.qt.nokia.com if you think Qt is the culprit here; attaching a test app to the report makes the fixes appear faster).

    Have you already removed the attribute? Does it still behave in the same way?
