Só na minha máquina.

Todo controle é uma janela, então é criada uma janela.
O "desenho" da janela, no geral é definido pelo estilo, e o tratamento do Windows para o controle é definido por classes padrão.
Esta parte define isso

Faz parte também desse estilo algumas mudanças visuais e/ou de comportamento.

A partir daí, o tratamento adicional vai ser feito por esta função/método.

Código: Selecionar todos

METHOD wvgControl:handleEvent( nMessage, aNM )

Cada evento passa por essa função, através de mensagens.
No geral é enviar/receber mensagens, a função acima recebe, wapi_SendMessage() envia.

Certos parâmetros não são compatíveis com Harbour, como já disse antes.

Resumindo:
GTWVG Pode funcionar como console ou GUI.
Só o esqueleto básico está pronto, com controles básicos e funções básicas.
Se falta alguma coisa é porque ninguém fez.

Comparar OOHG mostra exatamente do que eu venho falando.

Se uma simples MsgBox() não está padrão, já dá pra imaginar o restante.
A diferença entre as LIBs começa por aí.
Se essa função que é simples, e já existe padronizada, não está padrão, o que dizer das demais que não são padrão.

   ::wvgWindow:create( oParent, oOwner, aPos, aSize, aPresParams, lVisible )

Aqui se percebe a diferença na rotina de criar janela, que na OOHG é em C, e uma rotina pra cada controle.
Na GTWVG essa rotina está unificada, e em código Harbour, não limitando a conhecer linguagem C.

A questão principal é que isso faz parte dos fontes do Harbour.
Quando baixamos o Harbour, a hbwin e a GTWVG vém junto.

Comparando GTWVG e OOHG, com certeza OOHG tem mais recursos.
Mas comparando os fontes... prefiro da GTWVG.

A GTWVG tá aí, faz parte do Harbour, só precisa melhorias.
Acho que não vai ser expulsa do Harbour como a QT, porque não depende de nada externo.

A OOHG segue mais parecido com GTWVG, apesar de muitas rotinas em C, como mostrei acima, até mesmo pra criar a janela.

Só lembrando um dos exemplos da GTWVG, criando tudo dinâmico.

A GTWVG permite ser usada em console.
Mas ela também permite ser usada totalmente GUI.

Só falta alguém interesssado em implementar melhorias, e que tenha conhecimento pra isso.
Se for o que já existe na OOHG.... vai centralizar muitos usuários....

Uia... mais interessante ainda... dezembro/2003, há 13 anos atrás.
De lá pra cá, a grande mudança foi isso de criar controles usando a API do Windows, que recebou outro nome: gtwvg
Agora já não serão necessários 13 anos.
O próximo nome nem importa, o que importa é o conteúdo.
Pode ser gtwvg extended, ou oowvg.... rs

Só corrigindo o que passei errado:
a criação do controle não é em wvgWindow:Create(), e sim em wvgWindow:CreateControl()

Código: Selecionar todos

METHOD WvgWindow:createControl()
   LOCAL hWnd, aPosSz
   ::nID := ::oParent:GetControlId()
   aPosSz := ::getPosAndSize( ::aPos, ::aSize )

      ::exStyle, ;
      ::className(), ;
      "", ;                              /* window name */
      ::style, ;
      aPosSz[ 1 ], aPosSz[ 2 ], ;
      aPosSz[ 3 ], aPosSz[ 4 ], ;
      ::oParent:hWnd, ;
      ::nID, ;                           /* hMenu       */
      NIL, ;                             /* hInstance   */
      NIL )                              /* lParam      */
   IF wapi_IsWindow( hWnd )
      ::hWnd := ::pWnd := hWnd
      wapi_SendMessage( ::hWnd, WIN_WM_SETFONT, wapi_GetStockObject( WIN_DEFAULT_GUI_FONT ), 1 )
      ::hWndTT := wvg_CreateToolTipWindow( ::hWnd )
   ENDIF
   RETURN Self

como dá pra ver, é uma chamada à API do Windows CreateWindowEx(), passando os parâmetros necessários.
Igual às outras LIBs GUI, mas em código Harbour.
O posicionamento usa funções da GTWVG, porque converte linha/coluna para equivalentes em pixels.

Essa é uma parte que eu gostaria de alterar, porque a rotina que faz os cálculos se baseia em linha/coluna em números inteiros.
Bem que poderia aceitar decimais, por exemplo, linha 3.5, e converter pra inteiros somente antes de chamar a função de API.
Como essa rotina de cálculo está em C, não sei alterar.

Uia, saiu alguma coisa do progressbar.
Ainda não está totalmente funcional, por causa de parâmetros em C, por exemplo a combinação de dois números inteiros pra formar um número "long".

Se pegar as rotinas da OOHG já resolve, mas quero evitar rotina em C.
Talvez algum equivalente a MAKEINT() pra usar em Harbour.

Aliás está aí mais um exemplo do que venho dizendo, a progressbar da OOHG.

Pra usar esse mesmo fonte na GTWVG, pode até ser os mesmos fontes em C.
Mas tudo em C pode ser eliminado, já que a hbwin tem wapi_SendMessage(), e a GTWVG já tem a criação da janela.
Foi isso que eu fiz, mas não sei o equivalente desse MAKELONG(a,b) que está em C.

Obrigado Quintas,

Os códigos estão no forno e bem interessantes.

Os fontes que postei pra progressbar são da OOHG, e não fazem uso da HBWIN.
Dá pra incluir tudo na GTWVG usando do mesmo jeito, mas o ideal seria fazer uso da HBWIN e eliminar esse fonte em C.
Como dá pra perceber, faz uso de SendMessage(), que é equivalente a wapi_SendMessage().

Alguém por aí sabe qual o equivalente a MAKELONG( a, b ) ?

Quintas,

Procurei na MiniGui

#define MAKELONG( a, b ) ( ( LONG ) ( ( ( WORD ) ( ( DWORD_PTR ) ( a ) & 0xffff ) ) | ( ( ( DWORD ) ( ( WORD ) ( ( DWORD_PTR ) ( b ) & 0xffff ) ) ) << 16 ) ) )

Encontrei no google sobre ser a junção de dois números 16 bits, chutei e deu certo.

Mas no harbour-users, o Viktor me passou uma definição existente na hbwin:

Progressbar usando "marquee" (que apenas indica movimentação) ou que indica progresso.

Mas valeu assim mesmo.

A propósito, peguei o fonte do pushbutton e fiz as modificações pro progressbar, aliás... chamei de wvgcontrol pra encher de testes num lugar só.... rs
Usei a OOHG de referência para o que faltava ( o fonte postado anteriormente )

Foram essas rotinas que acrescentei para o progressbar.
Ainda não testei o smooth e o vertical.
Dá pra dizer que acabou sendo o mesmo progressbar da OOHG, que deve ser o mesmo da minigui, e o mesmo do Windows.

O fonte completo.
Com certeza misturando tudo fica mais complicado ainda, mas agora que alguns funcionaram já dá pra começar a separar.
