Detailed Description

Allows you to specify which handles are created by this handles provider.

It allows you to

replace handles with other handle implementations
(dynamically) disable or re-enable specific handles

Additional handles can not be added using this factory. The way to do this is to wrap the IEditHandles provided by PointHandlesProvider, and to insert additional handles in the IEditHandles::getList method.

◆ createElevationPointHandle()

virtual std::shared_ptr< IEditHandle > luciad::PointHandlesProvider::IHandleFactory::createElevationPointHandle	(	const std::shared_ptr< Observable< std::shared_ptr< Point > > > &	point,
		const std::shared_ptr< IPointEditAction > &	editAction,
		const std::shared_ptr< FeatureEditContext > &	context
	)

pure virtual

Creates a handle that allows you to move the Point vertically.

This method is only called when a 3D Map is used. While the handle is not already present, this method is called whenever the edited geometry changes.

Parameters

point	the geometry that is being edited
editAction	the move-point edit action, to be used by the handle. If a `constraint` was configured on the handles provider, this action applies that constraint when it is executed, providing a `PointChange` parameter with the `translation`.
context	the context

Returns: a new handle, or nullptr if no handle should be used

◆ isElevationPointHandleValid()

virtual bool luciad::PointHandlesProvider::IHandleFactory::isElevationPointHandleValid	(	const std::shared_ptr< IEditHandle > &	elevationHandle,
		const std::shared_ptr< Observable< std::shared_ptr< Point > > > &	point,
		const std::shared_ptr< FeatureEditContext > &	context
