Key-specific handlers, such as Key.onDeletePressed implicitly accept
the event. This means that the entire logic for the delete key must
be reimplemented, and e.g. Ctrl+Delete to delete the previous *word*
was missed.
Since all it has to do is handle the typing notification and format bar,
just use the already existing Keys.onPressed handler (which does *not*
accept the event) and add a case for Delete alongside Backspace.
First, the fill mode for the sticker images shouldn't stretch them.
Also make sure there is enough padding in the category so the image
doesn't appear larger than the button. Finally, set the source size for
the images so Qt can smooth them out better.
Currently both Enter and Ctrl+Enter send the message in ChatBar on
desktop. This might be unexpected behavior to users coming from other
chat applications (eg. WhatsApp, Telegram, Element) as those send
with Enter only by default. They allow changing send to Ctrl+Enter
in settings and other option is used to insert a newline.
BUG: 476758
Move the fucntionality of ActionsHandler into ChatbarCache and ActionsModel.
At this stage there wasn't much left that is was doing and the functionality could easily move.
Rework ActionsHandler as static helper functions.
The functions are now invoked from ChatBarCache so there is no need to pass an actions handler object around qml simplifying the code.
Move reply pane to use MessageContentModel. This means the reply pane component is no longer required.
This commit also limits the size of code and image componets in a reply to keep them from getting too huge.
So at the moment this remains behind the feature flag as this only adds a threadmodel and a basic visualisation. There is much more to come to get it ready for full release.
