how to make a cellview read-only?

JJ202502261359

I want to implement the "Make Read Only" function found in the Virtuoso menu using SKILL.

Virtuoso must revert to the last saved state without closing the layout GUI.

1. dbPurge() has an issue where the GUI window closes.
2. When proceeding with dbReopen("r") after hiUndo() multiple times,
   the undo operation is incomplete due to the limit on the number of undo steps.
3. If I open a layout in "r" mode and then modify it using `dbCreatePath`, the action cannot be undone.

Based on points 1, 2, and 3, implementing "Make Read Only" using Skill proved difficult.

Is there a possible way to do it

    cv=geGetEditCellView()
    dbRefreshCellView(cv) ; restore to what was on disk if there were edits
    dbReopen(cv "r") ; make readonly
