Exactly. Sorry it was my typo. I haven't tested above code and I've wrote it
only for this message. Now I see that it needs also yet another modification.
We need parameter to enable/disable RTE in this function. So final version
should look like:
typedef void * ( * QT_PARAM_FUNC ) ( int, BOOL );
[...]
QPageSetupDialog * hbqt_par_QPageSetupDialog( int iParam, BOOL fError )
{
QPointer< QPageSetupDialog > * pObj;
QPageSetupDialog * obj = NULL;
pObj = ( QPointer< QPageSetupDialog > * )
hb_parptrGC( &s_gcQPageSetupDialog, iParam );
if( pObj == NULL )
{
/* Not a QPageSetupDialog pointer item, check all registered
* descendant classes
*/
QT_PARAM_INFO * paramInfo = s_paramList;
while( paramInfo )
{
obj = ( QPageSetupDialog * ) paramInfo->pFunc( iParam, FALSE );
if( obj )
return obj;
paramInfo = paramInfo->pNext;
}
}
if( pObj == NULL )
{
if( fError )
{
/* RT ERROR - wrong parameter */
}
}
else
{
obj = * pObj;
if( obj == NULL && fError )
{
/* RT ERROR - object deleted by other code */
}
}
return obj;
}
If you want then instead of adding new parameter you can define that
iParam < 0 disables RTE and change this function to:
QPageSetupDialog * hbqt_par_QPageSetupDialog( int iParam )
{
QPointer< QPageSetupDialog > * pObj;
QPageSetupDialog * obj = NULL;
BOOL fError = TRUE;
if( iParam < 0 )
{
fError = TRUE;
iParam = -iParam;
}
pObj = ( QPointer< QPageSetupDialog > * )
hb_parptrGC( &s_gcQPageSetupDialog, iParam );
if( pObj == NULL )
{
/* Not a QPageSetupDialog pointer item, check all registered
* descendant classes
*/
QT_PARAM_INFO * paramInfo = s_paramList;
while( paramInfo )
{
obj = ( QPageSetupDialog * ) paramInfo->pFunc( -iParam );
if( obj )
return obj;
paramInfo = paramInfo->pNext;
}
}
if( pObj == NULL )
{
if( fError )
{
/* RT ERROR - wrong parameter */
}
}
else
{
obj = * pObj;
if( obj == NULL && fError )
{
/* RT ERROR - object deleted by other code */
}
}
return obj;
}
though maybe such version is less readable.
