[Kimchi-devel] [PATCH] Add the front end support for SPICE

This patch add the front end support of spice. 1 If there were a spice vm in host, show a "spice" button but not "vnc" in guest page. 2 click "spice" we can show a screen just like the demo http://www.spice-space.org/spice-html5/spice.html Signed-off-by: zhoumeina <zhoumein(a)linux.vnet.ibm.com&gt; --- ui/js/spice/atKeynames.js | 183 ++++++ ui/js/spice/bitmap.js | 51 ++ ui/js/spice/cursor.js | 92 +++ ui/js/spice/display.js | 806 ++++++++++++++++++++++++ ui/js/spice/enums.js | 282 +++++++++ ui/js/spice/inputs.js | 251 ++++++++ ui/js/spice/jsbn.js | 589 ++++++++++++++++++ ui/js/spice/lz.js | 166 +++++ ui/js/spice/main.js | 176 ++++++ ui/js/spice/png.js | 256 ++++++++ ui/js/spice/prng4.js | 79 +++ ui/js/spice/quic.js | 1335 ++++++++++++++++++++++++++++++++++++++++ ui/js/spice/rng.js | 102 +++ ui/js/spice/rsa.js | 146 +++++ ui/js/spice/sha1.js | 346 +++++++++++ ui/js/spice/spiceconn.js | 447 ++++++++++++++ ui/js/spice/spicedataview.js | 96 +++ ui/js/spice/spicemsg.js | 883 ++++++++++++++++++++++++++ ui/js/spice/spicetype.js | 480 +++++++++++++++ ui/js/spice/ticket.js | 250 ++++++++ ui/js/spice/utils.js | 261 ++++++++ ui/js/spice/wire.js | 123 ++++ ui/js/src/kimchi.api.js | 21 + ui/js/src/kimchi.guest_main.js | 26 +- ui/pages/guest.html.tmpl | 1 + 25 files changed, 7443 insertions(+), 5 deletions(-) create mode 100644 ui/js/spice/atKeynames.js create mode 100644 ui/js/spice/bitmap.js create mode 100644 ui/js/spice/cursor.js create mode 100644 ui/js/spice/display.js create mode 100644 ui/js/spice/enums.js create mode 100644 ui/js/spice/inputs.js create mode 100644 ui/js/spice/jsbn.js create mode 100644 ui/js/spice/lz.js create mode 100644 ui/js/spice/main.js create mode 100644 ui/js/spice/png.js create mode 100644 ui/js/spice/prng4.js create mode 100644 ui/js/spice/quic.js create mode 100644 ui/js/spice/rng.js create mode 100644 ui/js/spice/rsa.js create mode 100644 ui/js/spice/sha1.js create mode 100644 ui/js/spice/spiceconn.js create mode 100644 ui/js/spice/spicedataview.js create mode 100644 ui/js/spice/spicemsg.js create mode 100644 ui/js/spice/spicetype.js create mode 100644 ui/js/spice/ticket.js create mode 100644 ui/js/spice/utils.js create mode 100644 ui/js/spice/wire.js diff --git a/ui/js/spice/atKeynames.js b/ui/js/spice/atKeynames.js new file mode 100644 index 0000000..e1e27fd --- /dev/null +++ b/ui/js/spice/atKeynames.js @@ -0,0 +1,183 @@ +"use strict"; +/* + Copyright (C) 2012 by Aric Stewart <aric(a)codeweavers.com&gt; + + This file is part of spice-html5. + + spice-html5 is free software: you can redistribute it and/or modify + it under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + spice-html5 is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
