Open file tree

[jeluard]

Is there an API to open the fileTree and trigger the highlight of currently open file?
I’d like to make sure the fileTree is always open at theia startup.

@jeluard it is definitely possible, you can rebind FileNavigatorContribution to update the onStart lifecycle hook to perform something similar to the getting-started widget (to open the view on startup).

If you’d like to highlight a node in the tree, you can use the ApplicationShell to determine if there are any currently opened editors present in the application and highlight (selectNode) the tree node.

Additional Information:

• ApplicationShell: https://eclipse-theia.github.io/theia/docs/next/classes/core.applicationshell.html
• getting-started onStart: https://github.com/eclipse-theia/theia/blob/master/packages/getting-started/src/browser/getting-started-contribution.ts#L51-L57

Thanks!

Can I highlight a specific file in the FileTree using this method?

The highlight of a currently opened file is already supported, but if you’d like to highlight a specific node in the tree (given that you identify the node) you can call selectNode to highlight it.
