TGIS_LayerVector.GetNewUid method

DK11 for Delphi | GisLayerVector.TGIS_LayerVector.GetNewUid | Constructors | Fields | Methods | Properties | Events

Gets the Uid for a new shape.

Available also on: .NET | Java | ActiveX.


// Delphi
  function GetNewUid : TGIS_Uid; virtual;
// C++ Builder
  virtual TGIS_Uid* GetNewUid(void);


Type Description
TGIS_Uid 0 if Uid not assigned (in fact, only for pixel layers) or Uid value.


Use this method to find the Uid for a new shape. It simply uses GetLastUid method to determine the next available id. See example in GetLastUid.

When using this operation, never call any function which uses FindFirst..FindNext (i.e., any function which iterates through the shapes using it). So never use inside an operation like Locate etc.
