Add a RoomListItem-like button that opens a dialog
containing all of the messages that would result in a
highlight from the server (for example, the user is mentioned,
or @room is mentioned).
This is VERY rudimentary and will be completely reworked in the future
to take advantage of the existing TimelineView class, instead of
using a dialog like it does now. The button to show the mentions
also needs work.
When user is mentioned (via matrix 'highlight_count'), inactive
rooms will use a different color for the notification circle than
when only general unread messages exist.
work regardless of the theme choices the user makes. The code
now incorporates the contrast between the background color and the
color generated by the user_name when picking colors. It currently
has two 'big' issues:
1. Colors are not cached. I am planning on adding a QHash for this
a little later. This should improve performance by not calculating
the color for the same users over and over and over again.
2. Theme changes do not trigger the colors to get refreshed.
Currently, you will have to switch to a different room and back
to get the colors to refresh.
* Refactor widget items to use same interface
* Support audio, video, generic file for pasting
* Add utils function for human readable file sizes
* Set correct MIME type for media messages
This change also determines the size of the upload once from the
ContentLengthHeader, rather than seeking the QIODevice and asking for
its size. This prevents any future trouble in case the QIODevice is
sequential (cannot be seeked). The MIME type is also determined at
upload once, rather than using the QIODevice and the underlying data
inside.
* Allow for file urls to be used as fall-back
This fixes an issue on macOS which uses `text/uri-list` for copying
files to the clipboard.
