Probleme with SigC::Signal0

[Florent Blanchon <florent blanchon gmail com>]

Hello,

 

I'm using Plotmm with gtkmm.

 

I want to connect a signal to my curve to display.

 

the prototype of the signal is : SigC::Signal0<void> signal_curve_changed

 

So, the prototype of the callback should be :   void MyCallback(void)  ?

 

When I compile the project with :

 

  myCurve1->signal_curve_changed().connect( sigc::mem_fun(*this,&PlotTest::Curve_changed) );

 

With Curve_changed as : void PlotTest::Curve_changed(void)

 

the compiler make me this error : Invalid use of void

 

so I ca't use this signal....

 

 

Is anyone can help me...?

 

Thanks.

Flo
