[vtkusers] which keycode has a cursor-key ?

[Song Ho Ahn]

Hi Seffen,
Have you try assign keycode value with a specific number, for example;
char keycode = 28; // or 0x1C in Hex (RIGHT ARROW)

Also you might try the following functions rather than OnChar().
void OnKeyDown();
void OnKeyUp();
void OnKeyPress();
void OnKeyRelease();
