Ok, estão incompletos, tem rotina no fonte de teste que deveria ser função da classe do controle, etc. etc.

Agora é ir "recheando" cada um, com fonte PRG combinado com :sendMessage.

Controles mais complexos são a combinação dos anteriores, e rotinas de desenhar/escrever diretamente nas janelas.

Em último caso, é uma boa referência à API do Windows, e de como as coisas funcionam no Windows.

É tudo na base de janelas, para cada ítem da tela. Por isso o nome: Windows

Nota:
Talvez este tópico se encaixe melhor em contribuições.
Acabou mostrando o uso dos controles que existem no Windows, e todo básico do que acontece na programação Windows.
Infelizmente acabei misturando com a TUI, que era o assunto inicial.
De qualquer forma, tudo que foi usado está dentro dos fontes do Harbour, até mesmo a gtwvg.
