First crack at supporting touch screen for devices like Android and
iOS tablets. Part of https://github.com/kanaka/noVNC/issues/48.
This change detects touch screen support and uses the touchstart,
touchmove, touchend events in place of the normal mouse events.
In order to support middle and right mouse clicks, if the device is
a touch device, then three toggle buttons are added to the UI
representing the left, middle and right mouse buttons. These select
which mouse button will be sent when the screen is touched. All the
buttons can be toggled off, in which case then the touch events only
move the mouse cursor rather than sending a mouse down and mouse up
for touchstart and touchend events respectively. This allows fairly
full control with the mouse on touch screens.
API changes:
- include/canvas.js renamed to include/display.js
- Display.rescale() method removed from API. Use Display.set_scale() instead.
- Make logo configuration attribute of Display and display it when
clear() is called if it is set.
API deprecations:
- use RFB onUpdateState instead of updateState.
- use RFB onClipboard instead of clipboardReceive.
See https://github.com/kanaka/noVNC/wiki/ModuleAPI for detailed noVNC
modules and API description.
Expand and normalize the event/callback interfaces. Standize on
"onEventName" form for callbacks.
Callback Renames:
- RFB updateState -> onUpdateState
- RFB clipboardReceive -> onClipboard
- Keyboard keyPress -> onKeyPress
- Mouse mouseButton -> onMouseButton
- Mouse mouseMove -> onMouseMove
Callback Additions:
- RFB onPasswordRequired
- RFB onBell
- RFB onFBUReceive
- RFB onFBUComplete
Other:
- Add array type support to Util.conf_default()
- Removed a bunch of routines from the Display API that were just used
internally and not actually by noVNC: flush, setFillColor,
imageDataGet, imageDataCreate, rgbxImageData, rgbxImageFill,
cmapImageData, cmapImageFill.
- More keyboard/mouse logging when debug turned on.
- Some JSLinting
API change: changed include path variable from VNC_uri_prefix to
URI_INCLUDE since websock.js uses the variable and websock.js is no
longer just for noVNC (i.e. websockify is really the canonical
location for websock.js).
Changes to get web-socket-js to work. Right now it's a hack to get
around: https://github.com/gimite/web-socket-js/issues#issue/41. The
hack is to disable caching of the flash objects by appending
"?" + Math.random() to the end of the flash object path (but only when
using IE).
Rename the $() selector to $D() so that it doesn't collide with
the jQuery name.
The API change is that the 'target' option for Canvas and RFB objects
must now be a DOM Canvas element. A string is no longer accepted
because this requires that a DOM lookup is done and the Canvas and RFB
should have no UI code in them. Modularity.
