Signal connected to slot (or signal)

[Althor]

Hi

is there any method to check if a signal is connected to a slot yet?

regards.

Sure, there must be something in QMetaObject but I am to lazy to look into...
Some simple options which might solve your issue are: Use Qt::UniqueConnection when connecting or have a look at QObject::receivers().

You can also use connectNotify and disconnectNotify in your object.
