Issue by Signal to Slot via proxy

[anda_skoa]

When you do the connect in B, does "konfig" already exist?
Is it always the same instance?

Cheers,

Hi Casisto,
I think two other guys above get same issue as me, since we can't get the "relevant parts" of your problem, so we just can guess

1. as anda_skoa said, when/where you place the connect function must be valid. In some case it can be too late to "connect" when your dialog already called.
2. make sure the "this" of the receiver refer to the right object & you can use qDebug()<<sender(); inside the slot function to get exact information about the signal sender

Ok,

failure was found at minimizing... I had declare C in B, but call the show() by "parent", which is A. So, when I call it by "this" it is all right!

very much thanks here.
