  • Copy
  • Copy Row (if applicable)

• Context menu actions stay in sync with toolbar/command palette state and persisted settings.json view state.

Pull request overview

Adds a VS Code webview context menu to the Component Viewer/Core Peripherals tree-table, enabling copy and view-state actions that stay aligned with existing toolbar/command state and persisted settings.

Changes:

• Added webview context menu contributions (Copy / Copy Row / Periodic Update toggle / Exclude/Include Updates / Reset View State) with conditional visibility based on row state.
• Implemented webview-side context generation (selected-text aware Copy) and new extension commands to handle copy + reset actions.
• Added dynamic view-state clearing support and accompanying unit test coverage for the new reset behavior.

Note tested yet. Already some feedback from code review.

All good ✅

[jreineckearm]

Context menu behaves nicely, great job!

Just two feedback items

• It "feels" a bit odd that Reset View State collapses all nodes. Are we storing the expand states as part of the viewState setting? Or can we make that stop? A user got the collapse all button to achieve that.
• Suggestions for renaming commands/context menu entries
  • Component Viewer: Exclude from Updates --> Maybe better Freeze Component Display or Lock Component Display? It's not very clear what's excluded as you may not immediately understand the connection for which node this applies. And Exclude Component from Updates becomes a bit lengthy.
  • Core Peripherals: Exclude from Updates --> Maybe better Freeze Peripheral Display or Lock Peripheral Display?

Note: hard for me to predict how long the entries become with the suggested names. So, may need a bit of experimentation.

[jthuangarm]

Thanks for the feedback! The suggestions have been applied.
I chose Lock Display as we are using Lock icon.

Are we storing the expand states as part of the viewState setting?
No, it is stored in runtime. After stopping the session will clear the expand/collapse states

Re-tested, LGTM. Thanks!
