The issue with the selection prior to the fix can't be reproduced to
the same degree. It may have been some other bug that caused interaction
with the remote to be blocked.
Since we are setting "appearance: none" on our <select> elements, the
drop down arrow from the browser is hidden. This arrow doesn't fit in
visually though. This commit adds a new arrow from a simple data url
SVG. Its a dark triangle "pointing" downwards.
Note that we need to set the background to both the gradient and the
image here. Both use the "background-image" property for the graphic,
but since they are positioned differently we must use the general
"background" shorthand.
The class "noVNC_button" is only used for control bar buttons. Lets
clarify this in the CSS selectors by only applying styles to elements
with this class that are children of "#noVNC_control_bar".
In order to make the sidebar feel more like a GUI element from a real
application, we can disable the long-press image popup on iOS. Note that
this only has an effect on iOS devices.
When long pressing stuff in the sidebar on iOS, you can sometimes
accidentally select the container or the canvas. This results in a
broken state where the user can't interact with the session anymore.
This commit prevents this from happening.
We want to disable selections in the sidebar because when users drag
the handle, they could otherwise accidentally select stuff. This results
in a very broken state.
When selections are disabled, the sidebar also feels more like a GUI
element from a real application, and less like part of a webpage.
Without this fix we still get a "pointer" cursor on disabled inputs of
type "image" in Firefox. Currently, all our noVNC_buttons are
<input type="image">. Reported to firefox here:

We depend un such modern things anyway, having these kinds of properties
are more confusing than helpful. Let's not give the impression that we
make any attempt to work in old browsers.
The clipboard textarea could potentially shrink further than what was
possible for the header text elements, which looked a bit broken. In
that regard, a min width is introduced for the textarea.
All panels should be limited in this way, not just the clipboard panel.
One additional upside of this is that the numbers used to calculate the
max-width are closer by, in the code. This hopefully makes it easier to
avoid mistakes in the future.
Makes it a more independent element responsible for it's own positioning
and vertical centering. This makes the hint easier to adapt for external
CSS styles and makes it possible to remote the fixed size if needed.
After the user has "followed" the hint by dragging the handle to the
other side, the control bar will switch to that side. Once this has
happened, we will now hide the hint until the user starts over by
dragging the handle again.
This change was added to make the hint feel more like a "hint" and less
like a permanent GUI element. It isn't as persistent and intrusive now.
Note that we don't want the act of hiding the hint to result in a
transition animation here.
This makes it easier for integrators of vnc.html to write their own
input and button styles.
It's also positive to cut a bit off from the size of the large base.css.
When the error handler itself causes an exception, it falls back to a
simple document.write(). This means the proper error dialog isn't shown
when this happens.
The focus changes that were added to the error handler in e1f8232b are
not crucial for its function. If these focus changes causes an exception
we can just ignore that.
When this error is shown, something has gone very wrong. It shows when
a bug in the JavaScript causes an uncaught error. In these scenarios we
dont want the user to be able to interact with the GUI or the remote
session, since we can't guarantee that things work.
This button fills no real purpose. It's easy to mark everything and
delete with either "Ctrl + A -> Delete" or, on touch devices, "long
press -> mark everything -> Delete".
Currently novnc will only retry once (assuming the server is unavailable) and then stop (as the detail from is unclean, usually "failed to connect"). Minor change will continue to reconnect every reconnect_delay seconds until either reconnected or user intervention cancels the attempt.
Most (all?) new APIs will require a "secure context", which generally
means served over TLS. We can expect crashes because of missing
functions if this requirement isn't fulfilled, so try to warn the user.
