This timer might fire after the Cursor object has detached from a DOM
element, causing crashes. This will likely not happen in real scenarios,
but the tests are quick enough to trigger this.
The new gesture detection code will always prevent the default behaviour
of touchstart, so this check no longer works properly. We might want to
add something similar to GestureHandler in the future, but let's wait
and see what use cases are requested.
With the new gestures we will simulate the cursor being in a different
location than any of the touch points. This is a bit too complex for the
Cursor class, so let's just explicitly tell it where we want the cursor
rendered.
The previous value made the detection too sensitive and it was very
difficult to scroll precisely. A value of 50 pixels should give similar
behaviour to systems that don't do fine grained scrolling.
This isn't really expected behaviour from a user, i.e. that an extremely
small wheel movement still gives a large scroll event in the remote application.
Add several single and multitouch gestures to simulate various mouse
actions that would otherwise be impossible to perform.
This replaces the old system where you could select which mouse button
a single touch would generate.
The code that used these were removed in the following commits:
* 9ff86fb718 (RFB._mouse_arr)
* bb6965f2e6 (old_requestAnimationFrame)
* 490d471c53 (Display._c_forceCanvas)
This allows using TigerVNC server with PAM authentication (e.g. agains
LDAP or other extensible authentication mechanisms)
Tested with TigerVNC server (Xvnc -SecurityTypes Plain -PlainUsers '*')
Should not break anything else, this method is tried last when all
other fail.
Tested in Firefox 74 and Chromium 80
If too much text is copied in the session, String.fromCharCode.apply()
would crash in Safari on macOS and Chrome on Linux. This commit fixes
this issue by avoiding apply() altogether. Also added test to cover this
issue.
As a rule, instead of hard-coding a behavior on specific platforms we
should do dynamic detection.
This commit moves away from always hiding scrollbars on Android and iOS
and instead detects the rendered width of scrollbars in the browser.
Internet Explorer seems to flag images as loaded prematurely, which
can result in rendering bugs. We can detect this by looking at the
dimensions though.
