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.

Description
Methods
|
procedure KeyDown(const Key: TKey; const C: Char; const Time: TX3DTime); override; |
|
This item has no description. Showing description inherited from TAbstractKeyDeviceSensorNode.KeyDown. React to key down/up events. This is used by TCastleSceneCore to communicate with this key sensor. Semantics follow TInputPressRelease behavior for EventType = itKey. This means that Key may be keyNone (if not representable as TKey) and C may be #0 (if not representable as char), but not both — at least one of Key or C must contains something useful. Also, 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. | |

procedure CreateNode; override; |
|
This item has no description. Showing description inherited from TAbstractKeyDeviceSensorNode.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. | |
Properties
|
property FdDeletionAllowed: TSFBool read FFdDeletionAllowed; |
|
Internal wrapper for property DeletionAllowed. This wrapper API may change, we advise to access simpler DeletionAllowed instead. | |
