Subject: 2 problems while developing for KDE
X-MARC-Message: https://marc.info/?l=kde-devel&m=98372698025086

If anybody has any suggestion...

1) Weird missing connections
I have a virtual base class with the following features:
    - inherits QWidget
    - define a virtual destructor
    - doesn't define any new signal/slot (no Q_OBJECT in header file)

A child class with the following features:
    - inherits my base class
    - defines a normal destructor
    - defines new signals/slots (Q_OBJECT appear in header file)

Then I get this warning when instantiating my child class:

QObject::connect: No such slot KMWClass::cleanupEventFilter()
QObject::connect:  (sender name:   'unnamed')
QObject::connect:  (receiver name: 'unnamed')

But I don't make my self this connection. So I don't know where it
comes from.

2) Can't use KMainWindow as child widget
For some reasons, I'd like to use a KMainWindow as child widget of
another widget (for example a QTabWidget). When the KMainWindow
is not inserted in a layout, it works OK, but if I insert it into a layout,
then the KMainWindow is not shown anymore. If I force it by calling
explicitely "show()", then it is shown as separate window.

Thanks for any suggestion.

Michael.
