Change style's to DATA

[sambomb]

I'm with a trouble to change a Buttombmp style(especificaly WS_TABSTOP) and a LOT of good programmers don't know how to change the style in execution...
I think that change the nStyle for logical Data will solve all this troubles...

Code: Select all

Ex.:  Redefine ButtonBMP oBtn;
        ID         100
        Prompt "Can be focused";
        Update;
        Action CanFocus(oBtn)

Procedure CanFocus(oObj)

   oObj:[red]WS_TABSTOP[/red] := !oObj:WS_TABSTOP
   if   oObj:WS_TABSTOP
      oObj:settext( "Can't be focused" )
   else
      oObj:settext( "Can be focused" )
   end
   
   oObj:Refresh()

Return

The only trouble I see is a lot of classes to be changed (or not I don't know how it can be done)

You can use:

SetWindowLong( oBtn:hWnd, GWL_STYLE, nXor( GetWindowLong( oBtn:hWnd, GWL_STYLE ), WS_TABSTOP ) )

Thanks Linares, I already discover how to change but it's difficult to understand.
