)
// Oxygene

Name Type Description
_path WideString full path of layer to be built; a connection string for SQL base shapes;
_extent ITGIS_Extent starting extent of layer - can't be zero sized
_type TGIS_ShapeType shape type supported by a layer
_dim TGIS_DimensionType dimension; for default layer dimension use TGIS_DimensionType.Unknown

Remarks

Use this method to build a new layer (prepare storage). Depending on layer type different files are created or used. For GIS_LayerSHP there are .shp and .dbf, GIS_LayerSQLAbstract uses .ttkls files.

To add a new layer to the viewer simply create one, use Build method with proper params, fill needed layer properties and use the viewer Add method.

Example

Here is a simple procedure to add a new layer to the viewer.
