[Qt-interest] signal and slot

[Malyushytsky, Alex]

I would highly recommend you to try to describing your questions clearly.
I am not a good writer myself - English is not my first language either,
but if people don't understand you they can't help.

I guess you want 1 slot executed as a reaction on the specific signal,
and second slot to be called after.

If yes, you connect mentioned signal with 1st slot, so this lot is called when signal is received.

Now you have a choice:
a) you can simply call second slot as an ordinary function at the end of the 1st slot  ( you need to have an access to the pointer ).
b) or in the class 1st slot belongs to, you add the signal, which you emit at the same place you would call the second slot in case a.
In addition you need to connect that signal to second slot.

Hope this helps.

Alex

But the other function will call the first slot,and in this case the second slot will not be called.

You could send out a user-defined signal inside the first slot and
create a connection between this signal and the second slot.

Thanks,
