Problemas com prompt/menuto - harbour

Abel · Mensagem por **Abel** » 23 Mar 2012 01:20

valeu, vou estudar estas rotinas de menu para ver se resolvo o problema de passar o mouse por cima..das
opcoes...e ele ir navegando..

Abel, na minha opinião o problema no está no menuto e sim na biblioteca API que controla o mouse e alguma interferência que o SO faz sobre ela.

Pablo, fiz uns testes e aparentemente qdo o menuto esta aguardando uma tecla, ele nao esta com o controle do mouse mrow() mcol() funcionando ele fica estatico esperando, coloquei um loop com inkey(0.1) e ele ja le o mrow() e mcol(), preciso adaptar algumas coisas ainda.

è possivel baixar o menuto.prg do xharbour para eu ver ?

Ahhh é ? Quê bom que está conseguindo, não se esqueça de postar o seu exemplo, assim é de utilidade para todos. Eu procurei e encontrei este código de menuto.prg:

Consegui, descobri os problemas e arrumei ...
Agora a barra rola tranquilo, nao executa a opcao se clicar fora do menu, e se abrir alguma outra rotina ela continua funcionando.

segue a rotina alterada e com os comentarios para facilitar as devidas adaptacoes de quem quiser.
é so retirar as //// e fazer um teste simples para ver como é executado, faciltando assim debugar.

Parabéns você conseguiu !
Eu compilei o seu exemplo junto com o menuto.prg alterado e rodou beleza !
Ao compilar deu erro pela falta da função COLORARRAY(), aí desabilitei e funciona sim !

PARABÉNS ! Gostei da sua perseverança, é assim que muitas vezes se consegue quebrar barreiras. Valeu !

mas forum é isso, a gente aprende e ensina, da uma dica, encaminha uma solucao e colabora para que todos possam melhorar seu profissional.
