Such as topic, defines two functions in the ancestor window f_setstart () and f_setend (), the function parameters and return values are empty, the function body is empty
Then also defines a function in the ancestral window f3 (), the function of f3 () code like this:

F_setstart ()

.

F_setend ()

Excuse me: the function body is empty function role here? It doesn't do anything.

Please help me, thank you for the first

CodePudding user response:

Thank you very much!
In addition to this kind of situation is there anything else?
I watched, the following code back function body empty behind these two functions are not being expanded

CodePudding user response:

Set aside or give up use, if it is empty just don't think about it for a while

CodePudding user response:

F_setstart () and f_setend () needs to be rewritten in the child window, but not all child window needs to be rewritten, need to rewrite, defined in the parent window is the code for the convenience of maintenance
