SigC::slot() (obj)
|
|
-----------------------
|
|
slot() can be applied to a object method to form a Slot with a
|
|
profile equivelent to the method. At the same time an instance
|
|
of that object must be specified. The object must be derived
|
|
from SigC::Object.
|
|
|
|
Sample usage:
|
|
|
|
struct A: public SigC::Object
|
|
{
|
|
void foo(int,int);
|
|
} a;
|
|
|
|
Slot2<void,int,int> s=slot(a,&A::foo);
|
|
|
|
