[Qt-interest] Unknown signal sender

[Tony Rietwyk]

Hi Lucas, 

 

Have a look at QObject.sender(), QObject.objectName() and QObject.connect().


 

The documentation is correct.  The example is a custom widget that emits its
own signal, and it connects them directly.  

 

In your case, you wanted to consume the signal, so you used a slot.  

 

Hope that helps, 

 

Tony.

 Thanks, that worked.

 

Btw, I think the documentation example from QSignaleMapper is wrong.

 

     connect(signalMapper, SIGNAL(mapped(const QString &)),
             this, SIGNAL(clicked(const QString &)));

 

Shouldnt this be SLOT at the second line?

 

     connect(signalMapper, SIGNAL(mapped(const QString &)),
             this, SLOT(clicked(const QString &)));

  

 

Atleast thats the way it worked for me.
