Virtual Key Codes

These are cross-platform defines for every distinct keyboard press on the computer. Every physical key on the keyboard has a virtual key code. So the "two" key on the top row of the main keyboard has a different code from the "two" key on the numeric key pad. But the 'w' and 'W' character are indistinguishable by virtual key code because they are the same physical key (one with and one without the shift key).

Use virtual key codes to detect keystrokes that do not have ASCII equivalents, allow the user to map the numeric keypad separately from the main keyboard, and detect control key and other modifier-key combinations that generate ASCII control key sequences (many of which are not available directly via character keys in the SDK).

To assign virtual key codes we started with the Microsoft set but made some additions and changes. A few differences:

  1. Modifier keys are not available as virtual key codes. You cannot get distinct modifier press and release messages. Please do not try to use modifier keys as regular keys; doing so will almost certainly interfere with users' abilities to use the native X-Plane key bindings.
  2. Some keys that do not exist on both Mac and PC keyboards are removed.
  3. Do not assume that the values of these keystrokes are interchangeable with MS v-keys.
