Why i am getting error when use new signal slot method ?

[Qt embedded developer]

@raven-worx no there is only one public slot named BlinkLabel()

@Qt-embedded-developer
the this pointer is an instance of the class G3_Scan?

btw: using the old connect syntax might silently fail, but it doesnt mean that the old syntax is working. You would need to check the return value if the connection was successfully established.

@raven-worx i made the mistake due to use of &qTScanning. now my code is working . but i am not getting why i can not use &qTScanning?

Hi
because qTScanning is already a pointer

[Qt embedded developer]

@raven-worx How to check return value of successful connection ?

[raven-worx]

@Qt-embedded-developer
return true -> success, false -> failed

but simply dont use the old connect syntax anymore

[Qt embedded developer]

@raven-worx sorry but can you give sample example ?

[raven-worx]

@Qt-embedded-developer

if( QObject::connect(qTScanning, SIGNAL(timeout()), this, SLOT(BlinkLabel())) )
    qDebug() << "GOOD";
else
    qDebug() << "BAD";
