If the room pane is below the default width (by user resizing or because
of narrow window), go to the room settings or a member profile will
automatically expand it as needed.
The pane goes back to its previous size once the settings/profile is
left.
If the window is narrow enough that expanding the pane normally would
reduce the timeline's width past its minimum, the pane is shown as an
overlay instead.
If the account passed to `saved_accounts.update()` doesn't exist in the
config file, return instead of failing with a KeyError.
An account can be absent from the file if "Remember my account" was
unchecked on login, or if the file hasn't been updated yet on disk after
login (race condition).
Enter/Return/Menu: open device menu
Space: toggle check device
Escape: uncheck all
Alt+R/F5: refresh device list
Alt+S/Delete: sign out checked or all sessions
<img> tags that either have a width and height (needed for QML to render
correctly) or the data-mx-emote attribute (if they have no width/height,
we assume 32x32) will be rendered inline.
QML's support for img tags with remote src URLs seems buggy on Qt 5.15
especially, not working sometimes. We need to download and cache these
images (like done for matrix media events), and use the local path in
the img's src.
- Refactor everything about HBox, and adapt all the pages and popups
that used it
- Replace HTabContainer by HTabbedBox
- Make boxes swippable
- Make esc presses in boxes click the cancel button
- Make all boxes and popups scrollable when needed
- Replace generic apply button icons in popups
- Fix tab focus for error and invite popups
- Rework (still WIP) the account settings page:
- Use the standard tabbed design of other pages
- Ditch the horizontal profile layout, hacky and impossible to extend
- Add real-time coloring for the display name field
- Implement a device list in account settings (Sessions, still WIP)
