Class TInlineNode

This item has no description. Showing description inherited from TX3DNode.BeforeTraverse.

Override these methods to determine what happens when given node is traversed during Traverse call. The main use of this is to operate on TX3DGraphTraverseStateStack.

Remember to always call inherited when overriding. In BeforeTraverse and MiddleTraverse you should call inherited at the beginning, in AfterTraverse inherited should be called at the end.

Besides changing StateStack.Top fields, you can do push/pop on the stack. Remember that if you do StateStack.Push in BeforeTraverse, and then you must call StateStack.Pop in AfterTraverse.

This item has no description.

You can override this to do anything after the Inline children were loaded. It's called only after actual loading occurred, e.g. it's not called when LoadInlined was called on the already-loaded node with CanReload = False.

This item has no description. Showing description inherited from TX3DNode.ParseAfter.

Called at the end of parsing this node (including children) in any encoding.

This item has no description. Showing description inherited from TX3DNode.DeepCopyCore.

Does actual DeepCopy work. You can override this to copy some more properties for descendants.

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.

This item has no description. Showing description inherited from TX3DNode.VRML1ChildrenSaveToStream.

Should SaveToStream save our VRML1Children. In this class default implementation returns True, this is what you will want in 99% of cases. It's useful to set this to false if you use VRML1Children internally, e.g. *Inline nodes.

Load inlined content now. If Inlined is already loaded: if CanReload = True then it will be freed and loaded again, else (if CanReload = False) nothing will happen.

Note that this has a really simple support for "load" field (this concerns VRML 97 amendment 1 "InlineLoadControl.load" and X3D (actually used also in VRML 97 handling) "Inline.load" fields). It simply doesn't do any loading when "load" = False.

Note that this doesn't perform setting the "load" field, or sending any notifications to Scene about "load" field. It's the caller's job to keep loaded state synchronized with "load" field value.

LoadInlined(false) will be called automatically, to ensure the inlined contents are always loaded. It will be called at the end of Parse (this is needed to handle VRML/X3D IMPORT/EXPORT mechanism), it will also be called in BeforeTraverse (in case you constructed node by code, not by parsing; this also happens when node was made by expanding a PROTO).

Parameters

Exported

If non-nil, we will assign here node names exported from the file. Used to handle IMPORT/EXPORT X3D mechanism.

This item has no description.

Call this to indicate that you loaded the inline contents directly, by using AddChild yourself.

Create node fields and events.

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.

This item has no description.

This item has no description.

The inlined content (loaded from inlined url). Nil if not yet loaded, or no loading was successful.

This is also kept in VRML 1.0 children list as VRML1Children[0], but for future it's better to not depend on that. But it will always be enumerated by things like TX3DNode.EnumerateNodes.

Internal wrapper for property Load. This wrapper API may change, we advise to access simpler Load instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

This item has no description.

Internal wrapper for property Url. This wrapper API may change, we advise to access simpler Url instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Internal wrapper for property BboxCenter. This wrapper API may change, we advise to access simpler BboxCenter instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

This item has no description.

Internal wrapper for property BboxSize. This wrapper API may change, we advise to access simpler BboxSize instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
