[Uml-devel] Re: What is #warning?

[Jens Krüger]

Hi Jonathan, 
I introduced this warning because I wasn't sure about the implementation of
the following code

bool UMLDoc::activateView ( int viewID ) {
        bool status = true;
        loading = true; //this is to prevent document becoming modified when 
activating a view

        for(UMLView *v = viewsNotActivated.first(); v; v = 
viewsNotActivated.next() )
                if ( v->getID() == viewID) {
                        status = v->ActivateAfterSerialize();
                        viewsNotActivated.remove();

                        loading = false;
                        return status;
                }
#warning this makes no sense ?
        loading = false;
        return status;
}

the loading variable is allways set to false in case of a return. 
I set this warning only for remembering to solve this question. If you are 
sure that the implementation is correct you can remove this warning.

Regards 

Jens
