Protected Sub cursorFirstInternal(
  ByVal _cursor As Integer,
  ByVal _viewerCS As Boolean,
  ByVal _extent As TGIS_Extent,
  ByVal _query As String,
  ByVal _shape As TGIS_Shape,
  ByVal _de9im As String,

Parameters

Name Type Description
_cursor int
Integer
cursor identifier (see TGIS_LayerVector.cursorOpen)
_viewerCS bool
Boolean
if True an the layer has been attached to the Viewer then expected _extent units are in a Viewer coordinate space; otherwise expected _extent units are in a Layer coordinate space
_extent TGIS_Extent extent of item to be found
_query string
String
query which must be matched by item; closely mimics SQL WHERE clause; for examples you can use 'AGE >= 18'; empty (default) means that no all items will match.
_shape TGIS_Shape if not nil, then only shapes matched _de9im matrix with _shape will be found
_de9im string
String
DE-9IM matrix of comparison
_skipDeleted bool
Boolean
set a skip deleted treatment; by default deleted items will be ignored

Remarks

Non internal version is unsafe in the event of any special overrides such as in TGIS_LayerVector.FindNext.
