This sample demonstrates the following:
- use buffers to create shapes
- set buffer size
- use FindFirst and FindNext to search for shapes on a layer
- use the function TGIS_Topology.Create
- use the topology function MakeBuffer
In this sample, select the buffer size to perform the selection of all
polygons that at least partially overlap with the area of the buffer.
The names of the selected polygons are listed in the box below the map
window.
