Accessors

onChanged

get onChanged(): Event<void>
Emit when the tree is changed.

Returns Event<void>
Implementation of Tree.onChanged
- Defined in packages/core/src/browser/tree/tree.ts:293

onNodeRefreshed

get onNodeRefreshed(): Event<CompositeTreeNode & WaitUntilEvent>
Emit when the children of the given node are refreshed.

Returns Event<CompositeTreeNode & WaitUntilEvent>
Implementation of Tree.onNodeRefreshed
- Defined in packages/core/src/browser/tree/tree.ts:301

root

get root(): undefined | TreeNode

- Defined in packages/core/src/browser/tree/tree.ts:278
set root(root): void
A root node of this tree. Undefined if there is no root node. Setting a root node refreshes the tree.
Parameters
- root: undefined | TreeNode
Returns void
Implementation of Tree.root
- Defined in packages/core/src/browser/tree/tree.ts:283

Methods

dispose

dispose(): void
Dispose this object.

Returns void
Implementation of Tree.dispose
- Defined in packages/core/src/browser/tree/tree.ts:273
