Hi and welcome.
It's hard to say what the problem is without you showing us any code.
Could you at least show the connect() call and the signal/slot
definitions?
A common error would be to have the function parameter names in the
connect() call - you have to omit them.
P.S.
Your mail is hard to read - try to spell check it before submitting to
the list.
Cheers,
Peter

U connct the 1st un 1st and the 2nd un direct aftr that.
In bth casses U use teh "connect" commd (mak sur you dont forgt any lettrs
or symbels and U dont spel it wrung). Forthermor U writte "SLOT(...)"
around yur slots and "SIGNAL(...)" round yur signalls. also be sur you hav
valid pointors too yur objeckts.

read the first un too! it iss rather good. all the ozzers between thos 2
are also worthe yur while!

I never intended to help you but to show you that your chat room dialect
is not appreciated here on this list! And obviously I was not the only
one. Choose an online chat room for kids if you want to keep on like this.
If you are not willing to spend the time to write your posts in a good
english (and it may well have grammatical errors as your lines above,
that's okay for most people), then why should anyone spent her precious
time to answer your question? Think about it - and then you are welcome
here again!
And please choose a meaningful subject next time: "Hi" is not
descriptive (and mostly reveals poorly asked questions).
Cheers, Oliver
p.s. Don't write to me in private!

I was also a student, learning Qt within 2 weeks when writing
www.pointshop3d.com. That was back in 2000. I never wrote a post to this
list in such a chat room style though!

*Your* post was rude in the very first place. I just wrote in the same
manner as *you* did, remember? So if you call this "rude" then you have
learned a lesson. Good.
In fact I actually *gave* you some valid hints, although they were
burried within the chat room dialect: "Dont confuse the slot()" meant
that the compiler does *not* complain when you write the name of the
slot wrongly - only at runtime you will get a warning message on stderr.
And "bring good parameters" meant that you must not write the
parameter's name in the connect call, *only* the type, e.g.
WRONG: connect (this, SIGNAL (foo (int i)),
this, SLOT (fooSlot (int i)));
GOOD: connect (this, SIGNAL (foo (int)),
this, SLOT (fooSlot (int)));

Wrong, see above.

Then *please stop doing so* for God's sake! You have just done so now a
2nd time! Check your recipient's field (To:) before hitting the "Send"
button! Is this so hard?

And in the post i was nowhere being rude. I was asking my QUERIES!!
(Remember??!! Lost are you??)
By the way, i also didn't specify any where in my post that only people
whose name is OLIVER should reply :P (get your eyesight checked!!)

Priya,
Such a pity that you seem to be more interested in engaging in a
flamewar than in your original problem with Qt.
Till Oliver Knoll gave you hints, even if they seemed rude to you.
> And your hints were useful to my dogs who understand
> your hints!!
This remark is disgusting and if taken literally raises interesting
questions.
P.S.
if you must flame, do it personally. While not all personal mail is
flame mail all flame mail is personal mail. (Yes, you can flame "the
list". Then it's... "personal" to the list (represented by its
members).) - see http://email.about.com/library/weekly/aa110998b.htm

Message 10 in thread
Can we all please stop this thread?
First, yes there was very poor grammar, and very poor spelling in the
OP. This is NOT a chat room, and showing no respect to us, will not get
you any back
Second, Till, was probably overly insensitive to you in his response...
However, if your read his original email, it was tongue in cheek...
(p.s. Sorry, it's friday, I could not resist...
)
Third, we are supposed to be professionals here.... Your comments about
dogs will not get you anywhere... Till has been around for years and has
been a huge resource for many a noob on the list.
Forth, NONE OF US get paid to be on this list. Don't like the responses
you get, pay us as a consultant, and we will be as nice as you ever
wish.
Scott

Peter,
I had sent the mail saying that she had sent me a rude email
privately. But she said i was rude because i emailed her privately. How
can a person who is seeking help be rude?
She insisted that i send this to the qt interest email address
only (you can see it in the post) and not to her on her private email
address. Its her choice. You can advise her about how to reply to
queries and not to be rude, if you wish to.
I had not started this purposely. She was trying to teach me a
lesson (in grammar rather than Qt) which is wrong on her part. She
should have minded her own business if she was not interested in helping
me regarding my query. I can show u what she had replied when i had
posted my question to the mailing list.
I am here to learn, but i cant tolerate anyone being rude to me.
I am not doing any harm by asking my doubts. I don't regret what i did.

I am male! Oliver is a male name. Just in case you are treating women in
the same tone you just did (that would explain maybe your absolutely
misplaced voice here!).

> How can a person who is seeking help be rude?
No! Wrong! I did not say your email was rude because you *sent it to me
in private* (= to my private email adress instead of to the list, as I
prefer it). I said your first post was rude (in reply to another email
that you had sent to me in private) *because you had written it in this
chat room dialect*. Don't confuse the facts, please!
And please go search the archive about "chat room dialect" and you will
quickly find out that this is not the place to use it here. And it had
been pointed out by 3 members of this list, including me.
So please take this as a strong advice or stop posting here.

And you failed twice in doing so.
> I had not started this purposely. She was trying to teach me a
I wasn't trying. I simply told you the facts: no chat room dialect
please in this list! It's not polite. People spend time to answer your
questions, so please invest your time to formulate the questions properly.
> lesson (in grammar rather than Qt) which is wrong on her part. She
No! Wrong again! I did not complain about *grammar* (in fact I wrote
that it's okay to have grammatical mistakes, I'm not a native english
speaker myself). I complained about your *chat room dialect*! Please
stick to the facts!

You don't need to show it, I posted it on this list, so everyone who is
interested in this useless discussion we're having has already read it.
>

And you are welcome to learn! Simply follow the advices you are given
and see how others ask their questions. Good question -> good answer.
> am not doing any harm by asking my doubts. I don't regret what i did.
Then you won't get any replies, at least not from me if you continue
like this (chat room dialect).
So, you have taken my point, appreciate it or not, but please don't
twist the facts from people who have been much longer on this list than
you studied! This is my last post regarding this issue.
Cheers, Oliver
p.s. Sorry to all others for the noise!

Hi Priya,
your mail is easier to read this time, but you should have sent it to
the list - not to me in private.
i suggest you check out the fine Qt Tutorial here:
http://doc.trolltech.com/4.3/tutorial.html
it demonstrates nicely where to do the connect() call.
Other useful links for Qt Beginners:
http://doc.trolltech.com/4.3/index.html
http://doc.trolltech.com/4.3/how-to-learn-qt.html
I hope you're using a current (4.3.x or 4.2.x) Qt Version.
Cheers,
Peter
