The chat page is complex and slow to create, which creates a visible lag
when user switches room.
Instead of throwing the pre-switch one away and
making a new one from scratch, keep the same page and update its user &
room ID for a big improvement in responsiveness. The rest is automatic
thanks to QML property bindings.
When using the focus(Previous/Next)Message keybinds, no message is
focused and the view has been scrolled up, focus the message in the
center of the view instead of returning to the list's bottom to focus
the most recent one.
In the composer, when the text cursor was inside a word starting
with a @ but not matching any username (thus the completion UI being
invisible), pressing up/down arrow would not do anything instead of
going to the prev/next line.
When there's a one line (emote or non-message) event with its avatar
shown and combinable events follow it, that first event delegate's height
is supposed to be one line with the avatar overflowing into
the following event's blank space.
This behavior hasn't been working for a long time. This commit restores
it, along with improving the related code's quality.
- Remove pointless confusing aliases for avatar properties
(smallAvatar, collapseAvatar, etc)
- Make some EventDelegate properties readonly as they should be
- Use Layout.preferredWidth/Height for avatarWrapper instead of both
minimum and maximum W/H
- Make the code cleaner and more declarative
- Start loading past events when the join state of the room changes,
e.g. when accepting an invite, load history right then
- Properly cancel the loading task when leaving the room chat page
Send a pseudo-reply consisting of two messages: a `m.text` which is just
a reply with an empty body, then the file event itself.
This is a workaround to the restriction imposed by the Matrix API,
which prevents us from simply attaching a reply to a media event:
https://matrix.org/docs/spec/client_server/latest#rich-replies
These cause problems with the composer alias parsing code.
If an alias from the config file has whitespace, only the first word
will be taken into account (ignoring any leading or trailing whitespace).
Simplify the code, make it more declarative, and improve the reliability
of sending typing notifications (notably when changing the used alias in
the middle of a message).
If the chat was opened under e.g. "@user1:example.org", but the
composer text is "o abc" where "o" is a composer alias for
"@other_account:example.org", save the composer text to state.json as
"@user1:example.org" and not the alias user.
thumbnail() and download() were remaining.
Use a direct and carefully chosen MatrixClient's methods instead to
avoid problems mentioned in the previous commit 7502c1.
If the display name of a user is blank (e.g. just a space character),
autocomplete it as a user ID.
If the display name starts or ends with whitespace, trim it.
Contact the server's .well-known API before anything to get
available login flows instead of blindly assuming it will be
m.login.password, and to get the server's real URL instead of
requiring users to remember that e.g. it's "chat.privacytools.io"
and not just "privacytools.io" despite user IDs making it look like so.
The server field will also now remember the last accepted URL.
Making the window narrow enough to switch to "mobile mode", then big
again would trigger a signal in SettingsView that switched focus to it,
even when it wasn't visible.
This required us to set the media downloaded local path on events
entirely from python instead of simply lazy-fetching them when needed
from QML, due to pyotherside's async nature and files that must be open
in a certain order.
