Jak správně vytvoření checkmenu? – C / C++ – Fórum – Programujte.com

Ahoj,

zkouším vytvořit checkmenu, ale nějak mi to nejde. Políčko stále zůstává zaškrtnuté, ikdyž na něj znovu kliknu.

Protože proměnou checkRules máš lokální, takže bude vždycky 0.

Nic co by nezpravilo #ifndef, aspo+n douf8m. :-D

musí se opravdu vytvořit globální proměnná? #ifndef,#define a #ifend nějak nefungujou. :-(

Musíš si pamatovat ten stav, takže globální proměnná je správná volba. Na globální proměnné není nic špatného :).
