Class TStringSensorNode
Unit
Declaration
type TStringSensorNode = class(TAbstractKeyDeviceSensorNode)
Description
Generates events as the user inputs a longer string on the keyboard, useful for example to simulate "input fields" in 3D.

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.

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.
