A little problem with signals
-
Hi everyone,
I am kind of new to the qt and i had this problem.
i have a signal defined as
@signals:
void dataReceived(QByteArray &data);@
and i am calling this function/signal like this,
@emit dataReceived(incoming_data);@and finally
@connect(serialPort, SIGNAL(dataReceived(const QByteArray &)), this, SLOT(slot_newDataReceived(const QByteArray &)));@
The problem is, i debug and see the data coming but when i said "connect", it should call this function @slot_newDataReceived(const QByteArray &)@ but nothing happens.
Sorry about my english,
Thanks -
You define a signal <code>dataReceived(QByteArray &)</code>, but you're trying to connect to a signal <code>dataReceived(const QByteArray &)</code>.

It works. i had so much work and i could have missed it. [/quote]Such things just happen. Having an eye on the debug help helps in such situations.
<code>Object::connect: No such signal Object::dataReceived(const QByteArray&)</code>.
