If the user has not been sent any messages, show a message in the quick access menu with an educational message. If the user can send private messages, also show a link to open the "new message" composer:
This also adds a general improvement to the quick-access-panel, to be able to show an `emptyStateWidget` instead of just a message if there is nothing to show in the panel, as well as initial general styles for empty state.
* Revert "Revert "A11Y: Switch tabs using the keyboard (#12241)" (#12260)"
This reverts commit 4c1e02d412.
* FIX: Make sure that the "menu-link" is present when a plugin adds a tab.
Other changes:
- We put the notification tab first using JS instead of CSS. It's important because of the tab number data attribute, which the keyboard navigation uses.
- We only set the button id from the attrs object if it's a tab. Otherwise, it conflicts with the topic footer button
* A11Y: Switch tabs using the keyboard
According to the WAI-ARIA Authoring Practices, tabs should be navigable using the left/right arrow keys.
Additionally, the screen reader couldn't correctly announce that a tab was selected when clicking the tab icon. To fix this, we made the SVG icon non-clickable and set the "aria-hidden" attribute to true.
* Handle navigation events using appEvents
- The icon for the “view all” controls in the panels have no accessible alternative.
- Because the “Log Out” and "Do Not Disturb" elements in the preferences tab are an <a> element without an href attribute, it is not keyboard focusable and therefore not keyboard focusable. Use a button element instead.
The notification panel gets resized and the JS uses maxWidth of 320.
This tends to fight with the CSS causing notifications to "jump" a bit when a new one lands.
A first step to adding automatic dark mode color scheme switching. Adds a new SCSS file at `color_definitions.scss` that serves to output all SCSS color variables as CSS custom properties. And replaces all SCSS color variables with the new CSS custom properties throughout the stylesheets.
This is an alpha feature at this point, can only be enabled via console using the `default_dark_mode_color_scheme_id` site setting.
* Extract QuickAccessPanel from UserNotifications.
* FEATURE: Quick access panels in user menu.
This feature adds quick access panels for bookmarks and personal
messages. It allows uses to browse recent items directly in the user
menu, without being redirected to the full pages.
* REFACTOR: Use QuickAccessItem for messages.
Reusing `DefaultNotificationItem` feels nice but it actually requires a
lot of extra work that is not needed for a quick access item.
Also, `DefaultNotificationItem` shows an incorrect tooptip ("unread
private message"), and it is not trivial to remove / override that.
* Use a plain JS object instead.
An Ember object was required when `DefaultNotificationItem` was used.
* Prefix instead suffix `_` for private helpers.
* Set to null instead of deleting object keys.
JavaScript engines can optimize object property access based on the
object’s shape. https://mathiasbynens.be/notes/shapes-ics
* Change trivial try/catch to one-liners.
* Return the promise in case needs to be waited on.
* Refactor showAll to a link with href
* Store `emptyStatePlaceholderItemText` in state.
* Store items in Session singleton instead.
We can drop `staleItems` (and `findStaleItems`) altogether. Because
`(old) items === staleItems` when switching back to a quick access
panel.
* Add `limit` parameter to the `user_actions` API.
* Explicitly import Session instead.
