Why doesnt this Work!
Message 1 in thread
Why does this Work?
connect(qationbutton, SIGNAL(triggered()), parse, SLOT(startSim()));
and Why doesnt this work startSim(); ??
I have posted around 4 emails about this subject, without anyone giving
me a clear idea what the problem might be.
I have posted the code, pseudo kode. And when I say why doesnt this
work, i mean the function is called but it gott timers inside and they
dont call the proper function.
startSim(){
QTimer *time = new QTimer(this);
timer->start(1000);
connect(timer, timeout, this, timeIncr());
now the interesting part is that this connect works perfect if the user
clicks on the button qactionButton (statement above) but if the startSim
slot is called as a function it wont work.

Please create a minimal compilable example that illustrates the problem
instead of trying to rewrite the code in your email. There is no way
that the code below is actually what you are using since it wouldn't
even compile; you create a new QTimer called "time" and then try to
start a QTimer called "timer".
The only thing I can think of based on your emails is that wherever you
are that you are calling startSim() explicitly in your code doesn't have
an event loop running, so therefore no signals/slots.
Usually if you post 4 times and don't get a response it means that you
aren't being clear enough in your email to show us what the real problem
is.

As i said its pseudo kode, and ofcourse i have pasted yesterday the
whole code, its 450 lines of code in just one of the files iam having
problems with. if i pasted the whole 1200 lines of code it would be too
difficult and none gott time to read trought it, therfor i tried to
minimize where i think the problem might be and. thats why i wrote the
pseudo code.
anyway its QTimer *timer = new QTimer(this); and timer is always used
not time. its just a typo.
but if you would like i can paste the code for that file:

I don't think your getting it.
First, none of us get paid to do you work... We don't mind helping, but
going through 450 lines of code, looking for 1 problem line... isn't
easy...
Looking at the example, since your talking about 1 method that's
broke...
YOU (as in not US) could probably reduce it into 20-30 lines of
compliable code.
Maybe even a project file, with what ever options you using...
Another thing, Im going to throw out... your attitude sucks... Ill say
it. No one owes you a solution. People are putting an effort in here,
and your response is that of a child who isn't getting the candy they
wanted.
Now as said before, I bet the problem is in either the event loop not
running (stated yesterday and again today) or you are connecting to the
timeout of the timer AFTER its already passed that time...
Another thing I notice, you should ONLY connect to the timer once... In
your "full" code exaple your connecting it EVERY time your start it.

Iam really sorry if I wrote like a child, Iam just frustrated because I
really could not understand where the problem could be and i debuged in
hundred different ways.
So again Iam sorry if I said something offending i know you people do a
great job offering your time to help us.

Posting the whole file is hardly what I mean by posting a "minimal
compilable example". As another email just pointed out, we are all
developers working on our own stuff and don't have time to run through
450 lines of *YOUR* code to find out what you're doing wrong. So forget
your project for now. Write a brand new application that just attempts
to do what you think you are seeing that is wrong. If you can get your
small application to fail, and you still don't understand why it's
failing, send that to the list. But often times the mere exercise of
writing that sample code will illustrate what you are doing wrong and
you will find the bug yourself. Some of us might have time to look over
20-30 lines of code and point out flaws we see, but we don't have time
to run through 450 lines of code, just to find the one line of code that
is causing the problem.

No, we don't like this - this is a mailing list for *questions*, not for
debugging other people's code.

Because the connect statement in startSim() should read (I guess):
connect( timer, SIGNAL( timeout() ), this, SLOT( timeIncr() ) );
I'm assuming that timeIncr is declared as a slot, etc.

Try creating an absolutely minimal code example... And explaing what
doesn't work clearly... Also, explain what YOU have done to debug and
diagnose.
Ie, I watch the debugger step into startSim as a method call, however,
the timer does not change its timer value.

As the others already stated, you weren't verbose and concise enough in
your question; this includes the subject you chose. However,

if you do it exactly this way, I'm just guessing that it doesn't work
because you don't connect the timeout *before* you start the timer...

What do you mean? i dont connect the timeout, please explain in detail

He means that these 2 lines should be switched:
>>> timer->start(1000);
>>> connect(timer, timeout, this, timeIncr());
Should be:
connect(timer, SIGNAL(timeout()), this, SLOT(timeIncr()));
timer->start(1000);
Which makes perfect sense to me.
