Connection problem with menubar using Designer

[nikau]

You've declared aboutAction inside your UI with QtDesigner, so you should refere to it like this:

connect( &ui.aboutAction, SIGNAL(triggered()), this, SLOT(about()) );

connect( &ui.aboutAction, SIGNAL(triggered()), this, SLOT(about()) );

To copy to clipboard, switch view to plain text mode 

If you run your code from console I guess you'll get message that object aboutAction doesn't exist.

Actually what seemed to work is the following

connect( ui.aboutAction, SIGNAL(triggered()), this, SLOT(about()) );

connect( ui.aboutAction, SIGNAL(triggered()), this, SLOT(about()) );

To copy to clipboard, switch view to plain text mode 

When would I use the &??

I don't recal having to call ui.action when doing this...

Well thank you for helping out :-)

Ups, I was writing fast from my memory

I think the answer is in QtAssistant:

bool QObject::connect ( const QObject * sender, const char * signal, 
const QObject * receiver, const char * method,
Qt::ConnectionType type = Qt::AutoConnection )   [static]

bool QObject::connect ( const QObject * sender, const char * signal, 
const QObject * receiver, const char * method,
Qt::ConnectionType type = Qt::AutoConnection )   [static]

To copy to clipboard, switch view to plain text mode
