class var OnFont: TFontEvent deprecated 'use TFontStyleNode.CustomFont or TCastleText.CustomFont';

Warning: this symbol is deprecated: use TFontStyleNode.CustomFont or TCastleText.CustomFont

Adjust the font. Assign here a callback which can modify a font. You can look at any font style properties to decide how to adjust the font, like Bold, Italic, Family.

You can always decide to leave the given "Font" instance at the default value, or to modify it.

The font instance set here is a TTextureFontData instance. You can load it from a TTF file by TTextureFontData.Create, or you can assign here a TTextureFontData instance defined by a unit generated by texture-font-to-pascal. See https://castle-engine.io/manual_text.php about using texture-font-to-pascal. In the first case, remember that it is your resposibility to free this font later, but only after all possible Text nodes using this font are destroyed.

Methods

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.

	`destructor Destroy; override;`
This item has no description.

class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;

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

Some nodes are present only in specific VRML/X3D version. This functions decides it.

For example some nodes can only work in VRML < 2.0, some others only in VRML >= 2.0. There are even some pairs of nodes: for example TConeNode_1 works with VRML < 2.0, TConeNode works with VRML >= 2.0.

NodesManager will use this.

Default implementation of this function returns always True. Generally, I don't try to set this too aggresively — in other words, for all cases when it's sensible, I allow nodes to be used in every VRML/X3D version, even when official specification doesn't. This means that when reading VRML 1.0 files actually a large part of VRML 2.0 is allowed too, and also while reading VRML 2.0 many constructs from VRML 1.0 (officially no longer present in VRML 2.0) are allowed too. I'm trying to support what I call a "sum of VRML 1.0 and 2.0".

In practice I only use this function when various VRML/X3D versions specify the same node name but

With different fields.
For example Cone and Cylinder have slightly different fields, due to the fact that VRML 2.0 resigned from using TSFBitMask fields.
With different behavior.
For example definitions of Sphere for VRML 1.0 and 2.0 are practically equal. However, the behavior from where to take texture and material info is different — in VRML 1.0 we take last Texture2, Material etc. nodes, while in VRML 2.0 we look in parent Shape's "appearance" field. So once again two different Sphere classes are needed.

	`function Font: TTextureFontData;`
Font used by this node, determined by our fields (like Bold) and OnFont.

procedure CreateNode; override;

This item has no description. Showing description inherited from TAbstractFontStyleNode.CreateNode.

Automatically generated node properties.

Do not edit this file manually! To add new properties: - add them to the text files in tools/internal/x3d-nodes-to-pascal/nodes-specification/ , - and regenerate include files by running x3d-nodes-to-pascal

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.
