<Solved> Pointer to Calling class is needed

[Casisto]

Hi there,

I've a problem with the old topic "Signal from one class to another class".

To clearify my situation:

I have A which calls B (a modal QDialog, so it is without parent). B has a button, when pressed a function in A is calling, this way works. But the other way round I have the problem...

I initialize B like this:

b = new B();

and later in the "openFunction":

b->setFixedSize(b->minimumSize());
testbshow();

and now, in B I want this:

connect(A, SIGNAL(CallB()), this, SLOT(FunctionB()));

Because B should be Modal I can't do anything like this (maybe, I'm only don't know how I get B modal with this line):

b = new B(this);

I hope someone has a idea what I can do, so that B can get a signal from A.
