Inheritance HierarchyNamespace: Telogis.GeoBase.ShapeUI
Assembly: geobase.net (in geobase.net.dll) Version: 4.99.0.0
SyntaxThe PolygonEntity type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
  | PolygonEntity |
Creates a polygon entity on the supplied layer with the supplied geometry.
|
Properties| Name | Description | |
|---|---|---|
 | BoundingBox |
The bounding box of this shape.
(Inherited from ShapeEntity.) |
| Fill |
Determines the color / style of the inside of the shape.
(Inherited from ShapeEntity.) |
| IsHighlighted |
Whether the entire shape is highlighted
(Inherited from ShapeEntity.) |
| IsSelected |
Whether this shape is selected.
(Inherited from ShapeEntity.) |
| Outline |
Determines the color / style of the outline of the shape.
(Inherited from ShapeEntity.) |
| Polygon |
The underlying polygon object.
|
| Priority |
The rendering priority of this shape.
(Inherited from ShapeEntity.) |
| Tag |
A tag for the entity, can be used to model any relevant data for the entity.
(Inherited from ShapeEntity.) |
Methods| Name | Description | |
|---|---|---|
| AddVertex |
Add a new vertex at the end of the polygon.
|
| BeginEditing |
Returns the PolygonEditState when the layer begins editing this shape.
(Overrides ShapeEntityBeginEditing.) |
| DeleteVertex |
Deletes the last modified (added, inserted or moved) point.
|
| DeleteVertex(Int32) |
Deletes the vertex with the specified index.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetArea |
Gets the total area of the polygon using a Pythagorean approximation.
(Overrides ShapeEntityGetArea.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetPoints |
Gets the polygon's vertices.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| HitTest |
Checks whether a location is within this polygon.
(Overrides ShapeEntityHitTest(LatLon).) |
| InsertVertex |
Inserts a vertex between two other vertices.
|
| MoveVertex |
Moves an existing vertex to a new location.
|
| Render |
Renders the underlying polygon.
(Overrides ShapeEntityRender(Graphics, RenderContext).) |
| RenderEdge |
Renders a specific edge. The edge is the one that starts at the vertex with the
specified index and ends at the next vertex.
|
| RenderVertex |
Renders a specific vertex.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| ValidateShape |
Determines whether the polygon is a complete loop, in which case it is valid.
(Overrides ShapeEntityValidateShape.) |

Event that is fired when the shape's bounding box changes.
(Inherited from ShapeEntity.) |
| FillChanged |
Event that is fired when the shape's fill brush changes.
(Inherited from ShapeEntity.) |
| GeometryChanged |
Event that is fired when the shape's geometry changes.
(Inherited from ShapeEntity.) |
| IsHighlightedChanged |
Event that is fired when the shape is highlighted or un-highlighted.
(Inherited from ShapeEntity.) |
| IsSelectedChanged |
Event that is fired when the shape is selected or unselected.
(Inherited from ShapeEntity.) |
| OutlineChanged |
Event that is fired when the shape's outline pen changes.
(Inherited from ShapeEntity.) |
| TagChanged |
Event that is fired when the shape's tag changes.
(Inherited from ShapeEntity.) |
