>Bochs creates a bx_keymap_c object named bx_keymap.
|
||
|
|
This object allows you to :
|
||
|
|
- load the configuration specified keymap file
|
||
|
|
- get the translated BX_KEY_* from your GUI key
|
||
|
|
|
||
|
|
You have to provide a translation function from string to your Bit32u key
|
||
|
|
constant. Casting will be necessary if your key constants are not Bit32u typed.
|
||
|
|
The function must be "static Bit32u (*)(const char *)" typed, and must return
|
||
|
|
BX_KEYMAP_UNKNOWN if it can not translate the parameter string.
|
||
|
|
|
||
|
|
What you have to do is :
|
||
|
|
- call once "void loadKeymap(Bit32u (*)(const char*))",
|
||
|
|
providing your translation function, to load the keymap
|
||
|
|
- call "Bit32u getBXKey(Bit32u)" that returns the BX_KEY_*
|
||
|
|
constant, for each key you want to map.
|
||
|
|
|
||
|
|
The file gui/x.cc implements this architecture, so you can refer to it
|
||
|
|
as an example.</PRE
