Scan Codes

Scan Codes

A key has two kinds of codes, and which one a command takes says which table is for it:

• KeyDown and KeyHit take the codes of the original, which are the DirectInput scancodes (1 to 237). A key has the same code as in the original. Keys that the original had a code for are all reported, including F13 to F15, Pause, Print Screen, the Windows keys, the menu key, the media keys and the international keys. Keys that DirectInput has no code for (F16 and above, Help, Undo and others) cannot be asked with them.
• VKeyDown and VKeyHit take the scancode of SDL (0 to 511), which is a USB HID usage and the position of the key, not the letter on it. Every key that the system reports has one, on every platform, and it does not change with the keyboard layout. F16 is 107, F24 is 115, Help is 117 and Undo is 122. Use these when a program has to know about every key.

Both kinds work with the Device argument for one keyboard, and both ask for the same key state. The key events $101 and $102 of BlitzPlus and HotKeyEvent use the DirectInput codes, as in the original. Some keys are taken by the system before a program sees them (Alt+F4, the Windows key on some systems, power and sleep keys). Those arrive when the system lets them through. GetKey is not affected by any of this: it still gives the characters that were typed.
