Struct TreeItem 

pub struct TreeItem { /* private fields */ }

Godot class TreeItem.

Inherits Object.

Related symbols:

• tree_item: sidecar module with related enum/flag types

See also Godot docs for TreeItem.

Not instantiable

This class cannot be constructed. Obtain Gd<TreeItem> instances via Godot APIs.

Final class

This class is final, meaning you cannot inherit from it, and it comes without I* interface trait. It is still possible that other Godot classes inherit from it, but that is limited to the engine itself.

pub fn notify(&mut self, what: ObjectNotification)

⚠️ Sends a Godot notification to all classes inherited by the object.

Triggers calls to on_notification(), and depending on the notification, also to Godot’s lifecycle callbacks such as ready().

Starts from the highest ancestor (the Object class) and goes down the hierarchy. See also Godot docs for Object::notification().

Panics

If you call this method on a user-defined object while holding a GdRef or GdMut guard on the instance, you will encounter a panic. The reason is that the receiving virtual method on_notification() acquires a GdMut lock dynamically, which must be exclusive.

pub fn notify_reversed(&mut self, what: ObjectNotification)

⚠️ Like Self::notify(), but starts at the most-derived class and goes up the hierarchy.

See docs of that method, including the panics.
