If you need to check some values, etc. you can use the function LogFile() or change the caption of the window, etc. Use other ways to report info without interfering with the focus :-)

Hi Antonio.
Sorry I didn't get it...
This isn't a bug ?
It is the expected behavior ?

There are many places in an event driven application (like the Windows GUI one) in which you can find strange behavior if the focus is altered.

Seems I am too dumb, still didn't understand.
Is this a bug or the expected behavior ?

Hard to say. You have to check without changing the focus and if the problem is still there it could be a bug.

you can use
debug function for bypass the focus in controls.

dbwin32.exe or dbgview.exe


Code: Select all  Expand view


function main()
   ?KDSDebug( version() )
return

FUNCTION KDSDebug( xVal, lReturn )
   DEFAULT lReturn := FALSE

   OutPutDebugStringC( CStr( xVal ) + IIf( lReturn, FINL, "" )  )

RETURN NIL

#pragma BEGINDUMP

/*definición de constante necesaria para compilador XCC de xharbour.com*/
#ifndef __BORLANDC__
   #define WINVER 5
#endif

#ifdef __XCC__
#endif

/*llamada a encabezados de api de xharbour y windows SDK*/
#include "hbapi.h"
#include "windows.h"

/*funcion wrapper de api para mostrar un valor en un depurador*/
HB_FUNC( OUTPUTDEBUGSTRINGC )
{
    PHB_ITEM szMsg = hb_param(1, HB_IT_STRING );

    if( szMsg != NULL )
    {
        OutputDebugStringA( hb_itemGetC( szMsg ) );
        OutputDebugStringA( "\n" );
    }
    hb_retc( "" );
}

#pragma ENDDUMP

Ok.

Since in the sample if I only replace wbrowse to xbrowse the problem disappears, no mater focus changing, it's clear to me that wbrowse i buggy !

And wbrowse should be avoided, deprecated to xbrowse, in order to avoid unpredictable behavior.

So I will hunt for wbrowse in all my code and replace with xbrowse.
