Question about functions in classes

[cwnelatury]

Hey

Let's you use the QtCreator ...


when you type the dot next to the object you get a list of functions that the object has....

On the right of the list that automatically drops down some have an inclined red rectangle with a key symbol next to it...

What do the function with the key icon mean??

Thanks in advance

They specify if the function is private / protected / public.
I dont, however remember what icon is for what,,, you can find yourself
