Update the user model so it also sorts by power level and update how we initialize the model to improve performance.
The following is also changed:
- Store a single `UserListModel` in `RoomManager` and use it for everything, this means we don't create extra models (incluiding the long initialisation for each in big rooms)
- By using the single model once it has loaded the users of the new room opening and closing the draw now happens instantly (previously the model would have to be loaded every time the drawer was opened).
- To stop the initial loading and room change of Neochat slowing down (as the `UserListModel` would be loaded before the `TimelineView` is shown) the initialisation of the model is delayed until the `TimelineView` has loaded. This prioritises showing some messages in the timeline over populating the model so in large rooms the user list will initially be blank, but this keeps the initial load snappier.
Improve the behaviour of jump to last unread message. The view will now jump as high as possible if the last unread message isn't loaded. This at least triggers more items to load which will eventually get the user to the last unread message.
Fixes#645
- Active space handling is moved from QML to RoomManager
- Active tab in SpaceDrawer (space / no space / DM) is unified in a single variable
- RoomList & RoomPage loading is simplified: We're always pushing a RoomPage now; if there is no room, a placeholder is shown
- SpaceHomePage is moved into RoomPage; This replaces the entire push/replace room/spacehome logic
- If the current room is a space, the space home is shown, otherwise the timeline
- The concept of "previous room" is removed entirely. If we're leaving the active room, the placeholder room page is shown
- When clicking on a space in the list, the space room list is switched and the space home page is shown
In short, these changes should (after some initial regressions) lead to a less crashy NeoChat :)
Make sure that messages are not marked as read when going back to the roomlist after entering a room when neochat is thin and only showing a single page
Fixes#642
Make sure that message delegates are getting the room object directly rather than requiring the assumption that currentRoom is declared somewhere higher up.
The fixes include:
- improving the timer to make it more reliable
- making sure a read marker is added when changin rooms, this is needed when the messages have already been loaded.
- increase the default timer to 10s to avoid the read marker disappearing and being re-added when a message arrive in quick succession.
BUG: 465300
Currently trying to scroll with this scrollbar is probablematic and it's
unlikely we will find an easy solution to fix it, so make it non interactible.
Fix opening a room in a new window. This is done by makeing the model top level parameters in RoomPage set from RoomManager but overwritten by RoomWindow
Move the functionality to cache the contents of a chat bar from the room directly and to a new ChatCache object. This works pretty much the same with a few extra check and balances, this also made it easy to put a test suite around the functionality so I did. The current functionality should be identical to what exists.
This is in prep for threads which will require managing even more caches if we create one per thread.
