RE: Connect a signal to a slot

Hi Melinda,  

To use signal/slots in macros, please take a look at the few example macros in $ROOTSYS/tutorials/gui...
To use signal/slots into an executable (i.e. a standalone application), you have to generate a dictionary for your class (see examples in $ROOTSYS/test) If it is not sufficient and your code still doesn't work, please send me (part of) your code, so I can take a look and give more details.  

Cheers,
Bertrand.

Subject: [ROOT] Connect a signal to a slot

Hi Rooters,

I'm writing a GUI and I would like to create a certain number of TGComboBox objects depending on a certain value of a prevoius selection in another TGComboBox. I create the method UpdateCombos(Int_t selection) but I'm not able to connect it. When I start the GUI I obtain the message that the slot UpdateCombos(int) doesn't exist. Is there someone that can suggest me how to do to connect in a correct way the signal to the slot?

Thanks,

Melinda
