Detailed Description

This handles provider can create handles to edit Polygon geometries.

It delegates its handle creation to a delegate IGeometryHandlesProvider for its exterior and interior PolylineRing instances.

Note: the handle to translate the entire feature is typically created by the IFeatureHandlesProvider. FeatureHandlesProvider does this by default.

Limitations of this handle provider:

• it does not create a handle to remove interior PolylineRing instances
• it does not create a handle to add new interior PolylineRing instances
• it does not prevent you from modifying the PolylineRing instances that overlap with other PolylineRing instances, or that self-overlap.

Constructor & Destructor Documentation

PolygonHandlesProvider()

Luciad.Edit.Geometries.PolygonHandlesProvider.PolygonHandlesProvider ( )

inline

Creates a new handles provider that can create handles for a Polygon geometry.

Member Function Documentation

CanProvide()

bool Luciad.Edit.Geometries.PolygonHandlesProvider.CanProvide ( Luciad.Utils.Observable< Luciad.Geometries.Geometry > geometry, Luciad.Edit.Features.FeatureEditContext context )

inline

Indicates if this handles provider can create handles for the given geometry.

Parameters

geometry	an observable geometry, cannot be null
context	the context. Contains additional information about the edited feature, cannot be null.

Returns

if this handles provider can provide handles and a translate action for the given Feature

Implements Luciad.Edit.Geometries.IGeometryHandlesProvider.

Dispose()

void Luciad.Edit.Geometries.PolygonHandlesProvider.Dispose ( )

inline

Equals()

override bool Luciad.Edit.Geometries.PolygonHandlesProvider.Equals ( object obj )

inline

GetHashCode()

override int Luciad.Edit.Geometries.PolygonHandlesProvider.GetHashCode ( )

inline

Provide()

Luciad.Edit.Handles.IEditHandles Luciad.Edit.Geometries.PolygonHandlesProvider.Provide ( Luciad.Utils.Observable< Luciad.Geometries.Geometry > geometry, Luciad.Edit.Features.FeatureEditContext context, Luciad.Edit.Geometries.IGeometryEditCallback geometryEditCallback )

inline

Returns the handles for the given feature.

Note: translation of features is handled by IFeatureHandlesProvider. So geometry handles providers should not provide handles to translate a geometry.

Parameters

geometry	the observable geometry for which to provide handles, cannot be null.
context	the context. Contains additional information about the edited feature, cannot be null.
geometryEditCallback	a callback that notifies the caller when the Feature has changed, cannot be null.

Returns

handles for the given feature. Never null.

Implements Luciad.Edit.Geometries.IGeometryHandlesProvider.

ProvideTranslateAction()

Luciad.Edit.Handles.ITranslateEditAction Luciad.Edit.Geometries.PolygonHandlesProvider.ProvideTranslateAction ( Luciad.Utils.Observable< Luciad.Geometries.Geometry > geometry, Luciad.Edit.Features.FeatureEditContext context, Luciad.Edit.Geometries.IGeometryEditCallback geometryEditCallback )

inline

Provides a translate action that can be used by the caller to add translation behavior.

A translation handle is typically added by an IFeatureHandlesProvider, for example the FeatureHandlesProvider implementation. It calls this method to retrieve a translate action, and uses it to create a TranslateEditHandle.

When ITranslateEditAction.Translate is called, the returned implementation must:

• apply a translation to the geometry
• apply this IGeometryHandlesProvider's constraint (if configured) to the translated geometry
• call IGeometryEditCallback with the resulting geometry

Parameters

geometry	the observable geometry for which to provide a translate action, cannot be null
context	the context, cannot be null
geometryEditCallback	a callback that notifies the caller of this method when a translation has occurred, cannot be null

Returns

a translate action. Never null.

Implements Luciad.Edit.Geometries.IGeometryHandlesProvider.

getset

The IGeometryHandlesProvider that is used to provide handles for the exterior and interior PolylineRing instances.

[get]

Returns the IGeometryHandlesProvider that is used to provide handles for the exterior and interior PolylineRing instances.

[set]

Sets the IGeometryHandlesProvider that is used to provide handles for the exterior and interior PolylineRing instances. If this method is not called, a default implementation is used.
