Enum Action

pub enum Action<NodeIdType> {
    SetSelected(Vec<NodeIdType>),
    Move(DragAndDrop<NodeIdType>),
    Drag(DragAndDrop<NodeIdType>),
    Activate(Activate<NodeIdType>),
    DragExternal(DragAndDropExternal<NodeIdType>),
    MoveExternal(DragAndDropExternal<NodeIdType>),
}

Expand description

An action the tree view would like to take as a result of some user input like drag and drop.

Variants§

SetSelected(Vec<NodeIdType>)

Set the selected node to be this.

Move(DragAndDrop<NodeIdType>)

Move set of nodes from one place to another.

Drag(DragAndDrop<NodeIdType>)

An in-process drag and drop action where the node is currently dragged but not yet dropped.

Activate(Activate<NodeIdType>)

Activate a set of nodes.

When pressing enter or double clicking on a selection, the tree view will create this action. Can be used to open a file for example.

DragExternal(DragAndDropExternal<NodeIdType>)

Indicates that nodes are being dragged outside the TreeView (but not yet dropped).

MoveExternal(DragAndDropExternal<NodeIdType>)

Triggered when dragged nodes are released outside the TreeView. Indicates that the nodes should be moved to an external target (e.g., another panel).
