>Christophe Bothamy, wrote the keymapping code for Bochs, provided these
instructions to help developers to add keymapping to a GUI.</P
><PRE
CLASS="SCREEN"
>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
