Hello all,
I have an AES32 sound card that I am trying to write a general control interface for using qt4. I'm wanting to register callbacks so that the interface will reflect changes made by other apps. Now I'm not entirely up to speed on the API, but from what I can gather, the callback can be registered to call a regular function, or to change a public class variable.
Since I decided to use qt4, everything is in classes. Is there any way to have the callback trigger a public class function? I guess I don't understand why you would want to use a public variable instead. Wouldn't you have to set up a means within the class to continually pole the variable to see if it has been changed? Or can the option to call a regular function be used to call a public class function as well?
Well, which callback do you have in your mind? A bit more specificically please...
