Ongoing tasks:

• Apply a yellow background highlight to messages that mention the current user

Difficulties:

To be honest, there are a large amount of difficulties but I finally almost figuire them out:

• Here is my main idea: In issue 229 , we don’t care the sender UserId, instead, only care the receiver UserId in a replied event.

Once self UserId is equal to the receiver UserId, we make a different draw logic to reply message’s background.

if let Some(mentions) = message.mentions() {
    let client = get_client().unwrap();
    let self_id = client.user_id().unwrap();
    new_drawn_status.mentioned_self = mentions.user_ids.iter().any(|x| x == self_id);
    if new_drawn_status.mentioned_self {
        log!("mentions_self: {}", self_id)
    }
}

• related code: The receiver UserId just in Mentions, whose father is Message in ruma.

  pub struct Mentions {
    #[serde(default, skip_serializing_if = "BTreeSet::is_empty")]
    pub user_ids: BTreeSet<OwnedUserId>,
  
    #[serde(default, skip_serializing_if = "ruma_common::serde::is_default")]
    pub room: bool,
  }
  

For this struct, just add a field mentioned_self to store if the receiver UserId equal to self UserId:

#[derive(Debug, Default, Clone, Copy, PartialEq, Eq)]
struct ItemDrawnStatus {
    profile_drawn: bool,
    content_drawn: bool,
    mentioned_self: bool,
}

WorkInsights:

At the end of draw_walk of RoomScreen:

let color = vec3(0.7, 0.3, 0.3);
item.as_view().apply_over(cx, live!(
    show_bg: true
    draw_bg: {
        color: (color)
    }
));
item.redraw(cx);
item.draw_all(cx, &mut Scope::empty());

The common message is do inside the RoomScreen. However, I don’t know why the common message still not can be apply_over to red though I forced apply_over all the widgets’ bg to red
