Cursor flashing when skipping a QLineEdit

Message 1 in thread

Hi,

I'm using this code ( it results from what ie learned here some time ago ) to 
test if a QLineEdit should get focus or not:

bool LineEdit::eventFilter( QObject *Object, QEvent *Event )
{
  bool SignalRet = TRUE;
  if ( Event->type() == QEvent::FocusIn )
  {
    emit When( &SignalRet );
    if ( !SignalRet )
      focusNextPrevChild( TRUE );
   }
  return(QLineEdit::eventFilter(Object,Event));
}

But, when a QLineEdit is skipped due to a FALSE return from When signal, a 
flashing cursor appears at this QLineEdit. If two or more QLineEdits are 
skipped at one QDialog, each one of them gets a flashing cursor.

The users doesn't like these "fake" cursors. How can i make this "fake" cursor 
disappears?

Thanks

Josinei R. L. Silva

Would returning 'true' help?

I.e. something like

 bool LineEdit::eventFilter( QObject *Object, QEvent *Event )
 {
   if ( Event->type() == QEvent::FocusIn ) {
	   bool SignalRet = true;
	   emit When( &SignalRet );
	   if ( !SignalRet )
	      focusNextPrevChild( true );
	   return true;
   }
   return false;
 }

?

It works :)

I used:


 bool LineEdit::eventFilter( QObject *Object, QEvent *Event )
 {
    if ( Event->type() == QEvent::FocusIn ) {
 	   bool SignalRet = true;
 	   emit When( &SignalRet );
 	   if ( !SignalRet )
              {
 	      focusNextPrevChild( true );
              return true;
              }
    }
    return false;
}

Well, not exactly like this because my eventFilter does somethings more. But 
return true makes the "fake" cursor disappears.

Thanks a lot

Josinei
