QComboBox values?

[rexi]

In that case you could connect the currentIndexChanged signal to a slot in your GUI class, convert the QString to an int and call the method from your application class. Of course, instead of calling the method directly you could also define and emit a custom signal which you connect to the slot from your application class. You can find an example in the Qt documentation.

The question is, why don't you want any Qt code in your application class? If that class has a slot, you have Qt code already in there.

Why dont u try as rexi said - convert QString to int in your slot ?

Still if u want a slot in ur application class with int parameter, then have a look at using QSignalMapper, though this will be lengthy way !
