pub struct UiTags(pub HashMap<String, Option<Arc<dyn Any + Send + Sync + 'static>>>);
Expand description
User-chosen tags.
You can use this in any way you want,
i.e. to set some tag on a crate::Ui
and then in your own widget check
for the existence of this tag up the UiStack
.
Note that egui never sets any tags itself, so this is purely for user code.
All tagging is transient, and will only live as long as the parent crate::Ui
, i.e. within a single render frame.
