Move to the first shape in the Layer.
Syntax
// C# protected void cursorFirstInternal( int _cursor, bool _viewerCS, TGIS_Extent _extent, string _query, TGIS_Shape _shape, string _de9im, bool _skipDeleted );
' VisualBasic 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, ByVal _skipDeleted As Boolean )
// Oxygene protected procedure cursorFirstInternal( _cursor : Integer; _viewerCS : Boolean; _extent : TGIS_Extent; _query : String; _shape : TGIS_Shape; _de9im : String; _skipDeleted : Boolean ); virtual;
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.
