TGIS_Viewer.Items property

All layers.

Available also on: .NET | Java | ActiveX | Python.

Syntax

// Delphi
public
  property Items : TGIS_LayerAbstractList read;

// C++ Builder
public:
  __property TGIS_LayerAbstractList* Items = {read};

Type
TGIS_LayerAbstractList

USAGE: Access all loaded layers. Iterate for batch operations or enumerate layer collection. Use Get() to find by name.

layers = gis.Items
for each layer in layers
  layer.DeselectAll()

Do not manipulate Items directly. Use viewer methods and properties, such as: Open(), Close(), Add(), Delete(), Move(), and ZOrder.

Particularly calling Items.Clear() will not properly release layers. Instead, just call viewer.Close() method.
