[Spice-devel] How to adapt keymaps for spice-html5

[Eric Grammatico]

Hi Christophe,

Thanks a lot for your reply. 

I had a look in the direction you advise. Well... not that easy...

First I had modified the file /etc/X11/spiceqxl.xorg.conf with the following for inputs definition:

Section "InputDevice"
    Identifier "XSPICE POINTER"
    Driver     "xspice pointer"

    Option "CorePointer"
EndSection

Section "InputDevice"
    Identifier "XSPICE KEYBOARD"
    Driver     "xspice keyboard"

    Option "CoreKeyboard"
    Option "XkbLayout" "fr"
    Option "XkbModel" "pc104"
    Option "XkbVariant" "latin9"
EndSection


I made a test just to see if this update made any impact.... exactly not at all...

Then, I had a look in atKeynames.js. The KEY_Comma is wrong here. it's defined as "," and "<". On my keyboard it's "," and "?". I launch 'xev -event keyboard' from a terminal and pressing this key gave me the following result:

KeyPress event, serial 28, synthetic NO, window 0x5400001,
    root 0x399, subw 0x0, time 39177534, (81,88), root:(81,117),
    state 0x10, keycode 58 (keysym 0x2c, comma), same_screen YES,
    XLookupString gives 1 bytes: (2c) ","
    XmbLookupString gives 1 bytes: (2c) ","
    XFilterEvent returns: False


Thus I reported the keycode 58 in atKeynames.js for the element KEY_Comma. From there the key is not working anymore. No character printed when pressed.

The comments from the js file say:

* definition of the AT84/MF101/MF102 Keyboard

I had a look in Google to see a picture of a AT84.... Wahou ! Does someone believe a user will type on a AT84 using Xspice ? Last time I saw this kind of keyboard I was desperatly trying to have something out of RPGII on an IBM36....

I believe this AT84 is defined somewhere overwriting my keyboard config in spiceqxl.xorg.conf. From my point of view there is no reason to modified any javascript if on server side it's reading the wrong keyboard model/layout.

Thanks and regards,

Eric.
