function DirectEnumerateActive(Func: TEnumerateChildrenFunction): Pointer; override; |
|
This item has no description. Showing description inherited from TX3DNode.DirectEnumerateActive.
Enumerate all active child nodes of given node.
"Active nodes" are the ones affecting current look or collisions, e.g. from Switch node only one child will be enumerated. See Traverse for more precise definition.
"Direct" means that this enumerates only direct descendants, i.e. this is not recursive. See methods like Traverse or EnumerateNodes if you want recursive behavior.
This can enumerate both VRML1Children nodes and nodes within TSFNode and TMFNode fields.
Default implementation in this class enumerates all Children nodes of VRML 1.0. If you need to remove some children for VRML 1.0 (e.g. for Switch or LOD nodes) or add some children for VRML 2.0 you have to override this. You do not need to call inherited when overriding this — in fact, you should not, if you want to omit some nodes.
Stops and returns immediately if Func returns non-nil for some child.

constructor Create(const AX3DName: string = ''; const ABaseUrl: String = ''); override; |
|
This item has no description. Showing description inherited from TX3DNode.Create.
Constructor. Initializes various properties:
Name, BaseUrl are initialized from given parameters. The Fields, Events lists are filled in every descendant, to have all the fields/events defined by the specification. DefaultContainerField, and other node-specific stuff, is filled in descendants. This is actually implemented in CreateNode, that is called at the end of this constructor.

|
procedure CreateNode; override; |
|
Create node fields and events.

class function ClassX3DType: String; override; |
|
This item has no description. Showing description inherited from TX3DNode.ClassX3DType.
Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.
Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.
You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.

property EventSet_fraction: TSFFloatEvent read FEventSet_fraction; |
|
This item has no description. |
|
property FdControlPoint: TSFNode read FFdControlPoint; |
|
Internal wrapper for property ControlPoint. This wrapper API may change, we advise to access simpler ControlPoint instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

|
property ControlPoint: TAbstractCoordinateNode read GetControlPoint write SetControlPoint; |
|
This item has no description. |
|
property FdKnot: TMFDouble read FFdKnot; |
|
Internal wrapper for property Knot. This wrapper API may change, we advise to access simpler Knot instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
|
|
property FdOrder: TSFInt32 read FFdOrder; |
|
Internal wrapper for property Order. This wrapper API may change, we advise to access simpler Order instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
|
|
property Order: Integer read GetOrder write SetOrder; |
|
This item has no description. |
|
property FdWeight: TMFDouble read FFdWeight; |
|
Internal wrapper for property Weight. This wrapper API may change, we advise to access simpler Weight instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
