Struct TabGroupConstraints 

pub struct TabGroupConstraints { /* private fields */ }

Everything the container knows about a group’s place in the dock.

Pushed as one value rather than one setter per fact. These are read together, and a container that updates one while leaving another stale describes a dock that cannot exist — a group on a tiles canvas that still reports itself droppable, or a group beside siblings that still reports itself alone. Choosing a constructor forces the container kind to be stated; anything a constructor does not grant stays off, so a container that forgets something gets a group that does less rather than more.

Implementations

impl TabGroupConstraints

pub fn sealed() -> Self

A group with nowhere to go: locked, alone, unclosable. What a group starts as, before any container has placed it.

pub fn in_split(alone: bool) -> Self

A group in a split layout. alone when nothing sits beside it, which is what stops its last visible panel being dragged out and leaving the dock empty.

pub fn dock_locked(self, dock_locked: bool) -> Self

Whether the dock as a whole forbids rearranging.

pub fn collapsed(self, collapsed: bool) -> Self

Whether the group is folded away to a strip of tabs with no content.

pub fn closable(self, closable: bool) -> Self

Whether the container allows this group’s panels to be closed at all. A dock’s last group sets this false so the dock cannot be emptied.

pub fn is_alone(&self) -> bool

Whether nothing sits beside this group in its tree.

pub fn is_locked(&self) -> bool

Whether the group’s place in the dock is fixed.

The dock-wide lock is the whole of it. A tab group only ever sits inside a split — a tiles canvas holds panels directly and never a tab group — so there is no second way for a container to pin one down, and no separate is_dock_locked reader that would answer identically.
