Support toggling check state for all selected items in a tree view
- open can.ex2, apply
- open Multiblock Inspector, and select a bunch of rows.
- Now, if you click on the checkbox in any of the selected rows to toggle it, the selection gets cleared.
What we want instead, is following:
- leave selection state unchanged
- change check-state for all selected items to match the item that was clicked on.
The same behavior is expected of all checkable tree/table widgets including the variables, blocks, side sets, etc. selection widgets for readers like Exodus, CTH.
