My answer - yes it exist....data table wizard give me this table in db tables list....
Where is my problem?

Where do you show that widget? In the Designer?

Code:

---

#include <qapplication.h>
#include "inc/qformeditobjbase.h"
 
int main( int argc, char ** argv )
{
  QApplication a( argc, argv );
 
  // widget with one data table
  QFormEditObjBase frmObjEditBase;
  a.setMainWidget(&frmObjEditBase);
  frmObjEditBase.show(); 
 
  a.connect( &a, SIGNAL( lastWindowClosed() ), &a, SLOT( quit() ) );
  return a.exec();
}

You must connect to the database yourself. Connections that you define in Qt Designer are only used internally --- they aren't stored in a .ui file.
