how to check if a signal in emited or not??

Hi Every one,
in .h file, i defined a signal like

Code:

---

signals:
void mySig(arg list);

---

-- assume it in a.h

in .cpp file inside a method i'm emitting the signal like

Code:

---

emit mySig(arg);

---

in another file, b.h
i've a slot

Code:

---

void mySlot(arg list same as mySig);

---

and inside b file constructor i'm connecting this mySig to mySlot.

How ll i ckeck that if that signal is emited or not? plz help.

add qDebug in that place where you emit a signal.

i do not really understand what you mean, but if you only want to check if you code works,
type "qDebug() << "signal/slot works"; (or what ever) and run your code to test... you'll see if the signal and slot are really connected

Or just put a breakpoint on the signal and run the code. If the breakpoint is hit, the signal works.

Thank you spirit for the reply. Actually i've declare the signal in .h but didn't define it in .cpp file.

Code:

---

a.h
a();
~a()
function();
signal:
void mySig(arg);// signal return type is void

---

and inside a function

Code:

---

a.cpp
function()
{
....
...
qDebug()<<"checking mySig";
emit mySig(arg);
qDebug()<<"mySig executed";
}

---

But is this the right way???

actually, you don't need to define signals in cpp, because moc do it for you.
this code is ok

Code:

---

a.cpp
function()
{
....
...
qDebug()<<"checking mySig";
emit mySig(arg);
qDebug()<<"mySig executed";
}

Thank you very much. and 1 more question. if i'm emitting the signal in a.cpp,
and in b.cpp

Code:

---

connect(a.obj, SIGNAL(mySig(arg)),this, SLOT(mySlot(arg)));

---

where mySlot(arg), is a public slot in b.h
Is this rightway to connect Signal and slot belongs from different class?
