[Qt-interest] Using Strings instead of SIGNAL(foo())

[Scott Aron Bloom]

Take a look at QMetaObject::invokeMethod( QObject *, char * )

 

The string sent it will have to be normalized using QMetaObject::normalizedSignature (gets rid of spaces etc)

 

That should od the trick.

Hi Scott,

Thats not what I am trying to do ... I want to take a string parameter, obtained from say the user ... and emit a Signal based on that ...   i.e., normally One would make the connection like

connect( this, SIGNAL( sigMySignal( ) ), object, SLOT( slotMySlot( ) ) );

I am interested in doing it as,

connect( this,  myStringSignal, object, SLOT( slotMySlot( ) ) );

and then somehow ....

emit FUNCT(myStringSignal);

I hope you understand what I want to do ?

thanks,
Hari

Are you trying to emit a signal with a single parameter as a string?

 

signals:

void sigMySignal( const QString &  ) ;

 

with a connection like:

connect( this, SIGNAL( sigMySignal( const QString & ) ), object, SLOT( slotMySlot( const QString & ) ) );

 

Will do the trick…

Hi,

I am interested in emitting a signal based on a string ... now since SIGNAL(foo) converts the function to a string ... I should be able to manage this ... right ?

Is this possible ? How would I go about doing this ?  

thanks,
Hari
