[Qt-interest] Question SLOT Macro & messing with the QObject::connect method

[Ian Thomson]

Hi, you have mistunderstood me.

The functions which you are connecting as slots must fall in to one of 
two cases:

1) Stored as string literals somewhere in your program. In this case, 
call SLOT() on them at the point they are declared and use the const 
char* result. E.g.

const char* slots[] = { SLOT(firstFunc()), SLOT(secondFunc()), 0 };

connect(myButton, SIGNAL(clicked()), myObject, slots[0]);

or

2) Not stored as string literals anywhere, so the connections are 
determined at run time only. In this case you want to use QMetaObject to 
find out what slots are available. This sounds like a different problem 
to the one you are having.

Cheers,
Ian.
