Before, we have had two different gradiant versions, one where the two
colors meet in the middle, and one where only the top part of the
element was the darker shade. This was easily missed. Let's standardize
on the latter alternative. This commit introduces a variable to make it
easier.
It was completely unnecessary that these two were separate, lets combine
them. The only difference was that the lower rule didn't apply for
<select>. That doesn't matter though, since padding-left and
padding-right are specifically set for <select> elements anyway.
Use the more specific background-color, and background-image properties
when setting the state backgrounds for the control bar buttons. This way
we no longer pollute all background related properties. It makes things
easier if we need to replace them in some states in the future.
Instead of marking the hover selector with ":not(:disabled)" we can
break out this into its own section. This makes things easier to read.
In order to ensure the correct selector prioritization we also reorder
the file a bit.
Use the more specific background-image property when setting
linear-gradient backgrounds for input elements. This way we no longer
pollute all background related properties. It makes things easier if we
need to replace it in some states in the future.
Some elements used grey text and background when disabled, and some used
opacity. It looked a bit old school to make the elements grey when
disabled. Let's use opacity for all input elements when disabled.
Use the new modern :focus-visible instead of :focus. This is only shown
when navigating using the keyboard.
And in the case of the control bar buttons, This means we can separate
the :focus and :hover styles. Instead of showing a lighter overlay (or
darker for selected) like we use for hover, lets use a more common
blue outline for focus-visible. This also means we can re-use the common
focus-visible from input.css instead of having a special one for control
bar buttons.
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.
It seems that Firefox has a bug where these are fired incorrectly when
we are in an <iframe>. The events also contain no useful details, so we
can't really do anything useful with them anyway.
This space that was added here was added to the parsed value of the
query variable. This broke any comparisons with the value, for example
"myvar=true" resulted in a value of "true ".
This was broken by f796b05e42
The commit also adds unit tests for webutil.getConfigVar() that will
detect problems like this in the future.
Passing parameters as part of the fragment could be considered
benifical from a security or privacy standpoint when compared to query
string parameters. The URL fragment parameters are not sent to the
server.
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.
This was done a bit arbitrarily before which could easily miss things,
end up in the wrong state and not trigger animations correctly.
This reverts commit c12e5b2b54 and fixes
things in a different way.
