Estimados,
Fiz pequenas alteracoes em minha HC-TWBrowse:
Code: Select all
CLASS TWBrowse FROM TControl
DATA bFooter
DATA lSumFooter INIT .f.
...
//----------------------------------------------------------------------------//
METHOD ReDefine( nId, bLine, oDlg, aHeaders, aColSizes, cField, uVal1, uVal2,;
bChange, bLDblClick, bRClick, oFont, oCursor,;
nClrFore, nClrBack, cMsg, lUpdate, cAlias,;
bWhen, bValid, bLClick, aActions ) CLASS TWBrowse
...
::bFooter = {||.t.}
::lSumFooter = .f.
...
return Self
//----------------------------------------------------------------------------//
METHOD Paint() CLASS TWBrowse
local n := 1, nSkipped := 1, nLines
local nSkip, nRealSkip
if ::lIconView
::DrawIcons()
return 0
endif
if ::nRowPos == 1 .and. ! Empty( ::cAlias ) .and. ;
Upper( ::cAlias ) != "ARRAY" .and. Upper( ::cAlias ) != "_TXT_"
if ! ( ::cAlias )->( EoF() )
( ::cAlias )->( DbSkip( -1 ) )
if ! ( ::cAlias )->( BoF() )
( ::cAlias )->( DbSkip() )
endif
endif
endif
// **********
if ::lSumFooter
::lDrawFooters := .t.
::aFJustify := ::aJustify
endif
// **********
...
return 0
//----------------------------------------------------------------------------//
METHOD Refresh( lSysRefresh ) CLASS TWBrowse
If ::Cargo != Nil .or. ; // Tree
!( ::nLen := Eval( ::bLogicLen ) ) > 0
Super:Refresh()
Else // Si hay elementos en la tabla
DEFAULT lSysRefresh:= .f.
If "B"$ValType( ::aFooters )
::DrawFooters()
EndIf
Super:Refresh( .f. ) // No borrar fondo, WBrwPane se encarga de eso !!
If lSysRefresh // OJO Usar con cuidado porque puede hacer agotar
SysRefresh() // el Stack :-(
EndIf
// **********
if ::lSumFooter
eval( ::bFooter )
endif
// **********
EndIf
return 0
