We would incorrectly show a "truncate" button for standalone images
which isn't applicable since there's no text. That check has been fixed,
and it doesn't seem to regress normal link previews.
Another is that if there's only an image, our layout would center the
image which looks awkward since almost everything else is left-aligned
in chat. This is also fixed, which notably matches up to Element Web's
behavior.
I added support for the hover link indicator as well. Someone could
maliciously hide it via Markdown but have a legitimate-looking link
preview, for example. You can check that by hovering over the link in
the message itself, but now the link preview is another way to confirm
that!
I added ellipses so it matches the other loading placeholder we have. I
also removed the spacing in it's layout, because there is more than
enough space inside of BusyIndicator itself that it makes the
additional spacing look odd.
Unfortunately a pretty common spam/annoyance online is putting "spam"
via abusing Unicode symbols - which is used for multilingual support -
in display names. This typically results in an unreadable word jumble in
our UI, which looks bad.
So I decided to put a stop to that by clipping some labels that could be
used for this crap. I didn't cover *everything* yet, but this at least
prevents these idiots from showing up in the completion menu, the room
member list and as authors for messages.
Apply all the required styling to show links, table, spoilers, etc in cpp. This also updates the method of revealing spoilers so now you can click to reveal then click again to hide.
Update `ChatDocumentHandler` so `RoomManger` is no longer required for saving the text in the chatbar between room switches. This is achieved by allowing `ChatDocumentHandler` to get the correct `ChatBarChache` itself rather than having to have it passed from `ChatBar.qml`. This avoids any race conditions.
Separate out a base `MessageContentModel` that can be extended to get the component types from different places. This is used currently for `EventMessageContentModel` but will be used later as part of the rich chat bar.
All display text is now in the text component so it never needs special casing. This also cleans up some of the model parameters so more things come from attributes including location and file data (which was already a qvariantmap anyway).
Also cleaned up the itinerary and file enhancement views,
Add a dev setting to allow relations to be sent to any message using the right click delegate menu. This shouldn't be a main feature, but since it's technically allowed in matrix this will help any future debugging
And optionally show an error message, if libQuotient gets one. This
helps in certain rare situations where you just *Cannot* download
something. Before, NeoChat would just reset the image or video without
telling you anything but now there's a nice big error message telling
you what's wrong.
The video thumbnail is no longer hidden while loading. This makes it
look less buggy (like NeoChat forgot what the thumbnail was) while
loading a large video. To help with contrast, a slight background tint
is added.
