    FNV24: [9QAG4]

    A control used to show a set of internal TreeItems in a hierarchical structure. The tree items can be selected, expanded and collapsed. The tree can have multiple columns with custom controls like LineEdits, buttons and popups. It can be useful for structured displays and interactions.

    Trees are built via code, using TreeItem objects to create the structure. They have a single root, but multiple roots can be simulated with hideRoot:

    To iterate over all the TreeItem objects in a Tree object, use getNext and getFirstChild after getting the root through getRoot. You can use Object/free() on a TreeItem to remove it from the Tree.

    Incremental search: Like ItemList and PopupMenu, Tree supports searching within the list while the control is focused. Press a key that matches the first letter of an item’s name to select the first item starting with the given letter. After that point, there are two ways to perform incremental search: 1) Press the same key again before the timeout duration to select the next item starting with the same letter. 2) Press letter keys that match the rest of the word before the timeout duration to match to select the item in question directly. Both of these actions will be reset to the beginning of the list if the timeout duration has passed since the last keystroke was registered. You can adjust the timeout duration by changing ProjectSettings/gui/timers/incrementalSearchMaxIntervalMsec.

    • class Control

      Base class for all GUI controls. Adapts its position and size based on its parent control.

    Conformances

    • protocol CustomStringConvertible

      A type with a customized textual representation.

    • protocol Equatable

      A type that can be compared for value equality.

    • protocol Hashable

      A type that can be hashed into a Hasher to produce an integer hash value.

    • protocol Identifiable<ID>

      A class of types whose instances hold the value of an entity with stable identity.

    • protocol VariantRepresentable

      Types that conform to VariantRepresentable can be stored directly in Variant with no conversion. These include all of the Variant types from Godot (for example GString, Rect, Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.

    • protocol VariantStorable

      Types that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.
