Move the whole RFB object to rfb.js. vnc.js is now just the loader
file. This allows an integrating project to easily replace vnc.js with
an alternate loader mechanism (or just do it directly in the html
file). Thanks for the idea primalmotion (http://github.com/primalmotion).
Also, JSLint the various files.
The following API changes may affect integrators:
- Settings have been moved out of the RFB.connect() call. Each
setting now has it's own setter function: setEncrypt, setBase64,
setTrueColor, setCursor.
- Encrypt and cursor settings now default to on.
- CSS changes:
- VNC_status_bar for input buttons switched to a element class.
- VNC_buttons split into VNC_buttons_right and
VNC_buttons_left
- New id styles for VNC_settings_menu and VNC_setting
Note: the encrypt, true_color and cursor, logging setting can all be
set on load using query string variables (in addition to host, port
and password).
Client cursor (cursor pseudo-encoding) support has been polished and
activated.
The RFB settings are now presented as radio button list items in
a drop-down "Settings" menu when using the default controls.
Also, in the settings menu is the ability to select between alternate
style-sheets.
Cookie and stylesheet selection support added to util.js.
To change the appearance of the cursor, we use the CSS cursor style
and set the url to a data URI scheme. The image data sent via the
cursor pseudo-encoding has to be encoded to a CUR format file before
being used in the data URI.
During Canvas initialization we try and set a simple cursor to see if
the browser has support. Opera is missing support for data URI scheme
in cursor URLs.
Disabled for now until we have a better way of specifying settings
overall (too many settings for control bar now).
Util.Debug, Util.Info, Util.Warn, Util.Error routines instead of
direct calls to console.*. Add "logging=XXX" query variable that sets
the logging level (default is "warn").
Logging values:
debug: code debug logging (many calls in performance path are also
commented for performance reasons).
info: informative messages including timing information.
warn: significant events
error: something has gone wrong
Some basic functions from mootools implemented in util.js.
Also, some more DOM separation. Move clipboard focus logic into
default_controls and canvas and out of vnc.js.
JSLint cleanup.
- All state/status updates go through updateState routine which
updates the status line also.
- Old firefox (and opera) don't support canvas createImageData, so use
getImageData as replacement.
- Add console.warn and console.error stubs so that firefox without
firebug doesn't crap out.
- If no WebSockets then error if no flash or if URL is location (flash
will refuse to load the object for security reasons).
