which some-more appropriate: getters setters functions?

is ever suitable dried "getmyvalue()" "setmyvalue()" settlement getters setters choice duty names api some-more obvious?

for example, suspect i have category c++:

public category someclass {
private:
    bool misvisible;

public:
    vacant draw();
    vacant erase();
}

i supplement functions get/set "misvisible" this:

bool getvisible() { relapse misvisible; };


void setvisible(bool visible) { 
    (!misvisible && visible) {
        draw();
    } else (misvisible && !visible) {
        erase();
    }

misvisible = visible;


}

however, equally illusory following methods instead:

bool isvisible() { relapse misvisible; };

void show() { 
    (!misvisible) {
        misvisible = true;
        draw();
    }
}

void hide() {
    (misvisible) {
        misvisible = false;
        erase();
    }
}

in brief, improved have unparalleled "setvisible(bool)" method, camber "show()" "hide()" methods? there convention, definitely inequitable thing?
