Class TStringSensorNode

This item has no description. Showing description inherited from TAbstractKeyDeviceSensorNode.KeyDown.

Send key down/up events.

This is used internally by TCastleSceneCore to notify this key sensor that it should generate proper X3D events.

Semantics follow TInputPressRelease behavior for EventType = itKey. This means that

- Key may be keyNone (if not representable as TKey)

- KeyString may be '' (if not representable as String)

- But you cannot have both (Key=keyNone) and (KeyString='') at the same time. At least one of them must contain something useful.

- key presses are affected by the "key repeat" feature of the OS (windowing system actually), so when user holds down a key — we get many key down messages.

- KeyString is a UTF-8 encoded String representation of the key user pressed.

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.

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