This involved a refactoring to move all the media handling functions
(downloading, opening externally, etc) out of the Event delegates and
into the EventList, which manage keybinds instead.
This should also be better for performance since all these functions are
no longer duplicated for every Event in view.
Other user-noticable change: clicking on non-image media will
always download and open them no matter if the room is encrypted or not,
instead of opening non-encrypted files in browser like before. It will
be possible to still do that with an "open externally" command later.
Current features:
- Show scaled up thumbnail while the full image is loading
- Click to alternate between scaling mode (or reset zoom if not 1x)
- Click outside of image to close
- Double click to toggle fullscreen
- Middle click to open externally (also for thumbnail in timeline)
- Right click anywhere to close
- Ctrl+wheel to zoom
- Click-drag to pan when image larger than window
The Timeline EventList is the only HListView that uses it. For other
list views, it interferes with items like text fields which need to set
cursor shape by themselves.
Adopt the correct behavior to get rid of
"QML Connections: Implicitly defined onFoo properties in Connections
are deprecated. Use this syntax instead:
function onFoo(<arguments>) { ... }"
- Find the last event that wasn't sent by us to update the marker to,
instead of picking whichever is the most recent
- Use the proper event ID instead of ID that could be a local echo
- Wait for the current marker update request to complete before trying
to send a new one
Previously, events for which the sender, target (state_key) or remover
was missing from the room members would have their profile fetched
from network when registering the event into models.
This could cause very slow past events loading times for rooms, since
the event registering function (which contained the profile retrieval
directives) is run sequentially event-by-event.
Missing profiles are now lazy-loaded when events come into the
user's view in the QML timeline.
