Olá todos,

Segue abaixo um exemplo de como mudar a cor/fonte do browse e das colunas:

Code: Select all  Expand view
// Browsing arrays using TXBrowse and change colors and fonts

#include "FiveWin.ch"
#include "hbclass.ch"
#include "xbrowse.ch"

//----------------------------------------------------------------------------//

function Main()

   local oDlg, oBrw
   local aSample := { { "Teste", "Teste", "Teste", "Teste", "Teste" } , ;
                      { "Teste", "Teste", "Teste", "Teste", "Teste" } , ;
                      { "Teste", "Teste", "Teste", "Teste", "Teste" } , ;
                      { "Teste", "Teste", "Teste", "Teste", "Teste" } , ;
                      { "Teste", "Teste", "Teste", "Teste", "Teste" } , ;
                      { "Teste", "Teste", "Teste", "Teste", "Teste" } , ;
                      { "Teste", "Teste", "Teste", "Teste", "Teste" } }

   override method SelFont  in   class  TXBrowse with MySelFont
   extend   class  TXBrowse with method SelColor

   DEFINE DIALOG oDlg FROM 2, 2 TO 20, 60 TITLE "right click on the listbox"

   oBrw := TXBrowse():New( oDlg )

   oBrw:SetArray( aSample )

   oBrw:nTop          := 0
   oBrw:nLeft         := 0
   oBrw:nBottom       := 100
   oBrw:nRight        := 200
   oBrw:lHScroll      := .f.
   oBrw:lVScroll      := .f.
   oBrw:nMarqueeStyle := MARQSTYLE_HIGHLROW

   for n = 1 to 5
       oBrw:aCols[n]:cHeader := "Coluna " + alltrim(str(n))
   next

   oBrw:CreateFromCode()

   oDlg:oClient := oBrw

   oBrw:brclicked := { |nRow, nCol| SHOWPOPUP( oBrw, nRow, nCol ) }

   ACTIVATE DIALOG oDlg CENTERED

return nil

//----------------------------------------------------------------------------//

static function SHOWPOPUP( oBrw, nRow, nCol )

     separator
     menuitem "&Mudar cor       da Coluna" action oBrw:SelColor( nColbrw,, .t. )
     menuitem "&Mudar Fonte     da Coluna" action oBrw:SelFont( nColbrw, .f. )
     menuitem "&Mudar cor/fonte da Coluna" action oBrw:SelFont( nColbrw, .t. )
     separator
     menuitem "&Retornar"  action oPopup:End()
endmenu

activate popup oPopup at nRow, nCol of oBrw

return NIL

//----------------------------------------------------------------------------//

return nil

return nil

Antonio,

Eu encontrei um problema na classe ´TFont´no método choose(). Para você simular o problema no exemplo acima faça o seguinte:

1º) Mude a fonte do browse
2º) Mude a fonte de uma coluna qualquer, aí a fonte do browse é toda mudada também, porque ???

Peço a todos interessados que testem e me reporte possíveis erros ok ?

Obrigado,

Rossine.

Antonio,

Aproveitando o tópico, seria interessante incluir o processamento da tecla "VK_TAB" para se focar o próximo/anterior objeto dentro da xbrowse. Segue código:

Code: Select all  Expand view

METHOD KeyChar( nKey, nFlags ) CLASS TXBrowse

...

      case nKey == VK_TAB .and. GetKeyState( VK_SHIFT )

           ::oWnd:GoPrevCtrl( ::hWnd )

      case nKey == VK_TAB

           ::oWnd:GoNextCtrl( ::hWnd )

      case nKey == VK_RETURN
...



Saludos,

Rossine.
