The problem with the GDK-DirectFB keyboard code is the dependency on a proper key map provided by the primary keyboard device. The keyboard device driver has to send hardware key codes and provide a mapping from each code to up to four different symbols depending on lock states (Shift+AltGr). DirectFB does not provide a key map if the driver doesn't do, but it translates between key identifiers and key symbols and does the key code to symbol lookup if there's a map. If there's no key code sent by the driver, there won't be a key code in the event sent to GDK-DirectFB. Check src/core/input.c for more details. GDK-DirectFB flaws: - only queries the primary keyboard for a map - does not support devices without a map properly - crashes if there's no keyboard at all (maybe fixed) I started working on a static key map within GDK-DirectFB to support simple remote controls or other devices without a map provided by the driver. Maybe you like to play with it, but I think the real fix should be done in DirectFB: - generate simple key map if none available - use key identifiers as key codes if none available - allow changes to a key map via API -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
