VSCode extension TreeView set selected

Question

I have created a TreeDataProvider and populated it with TreeItem s. I would like to be able to set the TreeItem that is selected based on the current editor window, like happens in the Explorer/Open Editors view.

I have looked through the API but cannot find any way to do this.

Answer 1

You can use the reveal() API that was added in VSCode 1.21.0 (February 2018) for this.

This requires you to first obtain a TreeView instance using createTreeView():

const treeView = vscode.window.createTreeView("viewId", {treeDataProvider: provider});
treeView.reveal(item, {select: true});
