| #define MGUI_NR_KEYS 255 |
Number of MiniGUI keys.
The number of MiniGUI keys is defined to 255 by default. This means that MiniGUI can destinguish 255 different keys with each has an unique scan code. The scan codes below 129 are defined for PC keyboard by default. If your system has a large amount of keys, you can define the scan code of keys ranged from 1 to 255 in your IAL engine. And your application will receive a MSG_KEYDOWN and MSG_KEYUP messages when a key pressed and released, and the wParam of the messages will be defined to be equal to the scan code of the key.
| #define NR_KEYS 128 |
The number of keys defined by Linux operating system.
For a PC box, NR_KEYS is defined to 128 by default. You can define some input events from an input device other than keyboard, e.g. your remote controller, as key events with different scan codes from those of PC's. MiniGUI can support 255 keys, and the constant is defined by MGUI_NR_KEYS.
| #define SCANCODE_USER (NR_KEYS + 1) |
The first key scan code different from OS defined ones.
You can define your special key scan codes like below
#define SCANCODE_PLAY (SCANCODE_USER) #define SCANCODE_STOP (SCANCODE_USER + 1) #define SCANCODE_PAUSE (SCANCODE_USER + 2)
to distinguish the keys on your remote controller.
