How to get the child by the specified name

You can get the child by the specified name with the method: mpfc::WSCbase_getChildInstance();

use mpfc;
                                                                                
sub event_procedure {
  my ($object) = @_;
  # get the child which name is "newvbtn_001"
  $child = $object->getChildInstance("newvbtn_001");
  if ($child != 0){
    # the child exists.
    $child->setVisible($mpfc::True);
  }
  return;
}
1;

In the example, mpfc::WSCbase_getChildInstance() seeks the child which name is "newvbtn_001" from the instance: "object" recursively, and returns it if finds or returns NULL if not.
