Add visibleStart/End properties to HListView that take into account the
ListView's originX/Y, and not just contentX/Y which can be largely
offset.
Use those new properties in EventList for message focusing (fix
ctrl+up/down sometimes incorrectly focusing the message at the middle of
the screen even when we're scrolled at the bottom), and detection of
when we can update the read marker (fix cases when we're scrolled at the
bottom but the read marker never updates).
When switching rooms, first load only the delegates in the user's view
and wait a second before expanding the cacheBuffer and loading more
delegates outside the view. This reduces the amount of delegates to load
all at once by 3x.
When a chat page is recycled, set the eventList model to
null, wait for any animations to finish, then explicitely reassign it.
This prevents from model from randomly mixing up old and news delegates.
For rich text (rendered HTML) fields and areas, the selectedText
property for some reason contains "\u2028" or "\u2029"
characters that look like newlines in Qt programs but are just
invisible anywhere else. Translate them to normal "\n".
menu.mediaType can be an enum value, which includes 0 to represent a
web page link, or null if no link was right clicked.
Check for null explicitely when evaluating whether the menu entry
should be displayed.
Sometimes and randomly, a HListView/HGridView delegate's
add/populate transition will stop before completion.
This especially happens on startup when loading a large room list,
one room might get stuck and left tiny or invisible, despite its
normal space still being taken.
Returning a Future doesn't work on Windows for some reason
(https://github.com/thp/pyotherside/issues/116).
Instead of using these objects from QML to cancel running coroutines,
call a Python QMLBridge function that takes a coroutine UUID and will
take care of the cancelling.
If user right clicked on the most recent event in the timeline
(index 0), a new message was posted in the room (the new index 0),
and the user right clicked on it, the EventContextMenu's `event`
property relying on the index would not detect any change and
thus would still target the previous event.
This affected options depending on this property like "Reply".
The problem was reproducible with any same index repetition, not just 0.
Use a single [userId, roomId] property for the chat page.
This gets read of the intermediate state where the userId property has
been updated but the roomId one not yet, which led to the page unloading
and reloading itself until both were properly set.
Side-effect: when starting Mirage after this commit for the first time,
the last saved page will not load and user must click a room or
other page manually.
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.
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
thumbnail() and download() were remaining.
Use a direct and carefully chosen MatrixClient's methods instead to
avoid problems mentioned in the previous commit 7502c1.
