Christophe Bothamy, wrote the keymapping code for Bochs, provided these instructions to help developers to add keymapping to a GUI.
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.
