If you edit an actor name, then delete the actor - it fails to be removed from the map in the editor. This is because the actor previews are keyed by ID. Editing their name edits their ID and breaks the stability of their hash code. This unstable hash code means the preview will now fail to be removed from collections, even though it's the "same" object.
Fix this by making the ID immutable to ensure hash stability - this means that a preview can be added and removed from collections successfully. Now when we edit the ID in the UI, we can't update the ID in place on the preview. Instead we must generate a new preview with the correct ID and swap it with the preview currently in use.
The Text element of these widgets was changed from display text to a translation key as part of adding translation support. Functions interested in the display text need to invoke GetText instead. Lots of functions have not been updated, resulting in symptoms such as measuring the font size of the translation key rather than the display text and resizing a widget to the wrong size.
Update all callers to use GetText when getting or setting display text. This ensure their existing functionality that was intended to work in terms of the display text and not the translation key works as expected.
- Add prefixes to all message keys to provide context
- Use messages with attributes for some UI elements (dropdowns, dialogs, checkboxes, menus)
- Rename some class fields for consistency with translation keys
