Tree-table selection logic

SelectionHandling

The current tree selection logic is not optimal because it only refers to individual rows. A row is either selected or not - it is not possible to see whether there are other selected rows under a collapsed row.

The logic should be extended so that the following states are recognizable in a tree table with multiple selection at the selection marker:

Neither the node nor any of the children (recursive) is selected.
Only the node, but none of the children (recursive) is selected.
The node is not selected, but some of the children (recursive) are selected.
The node is selected and some but not all of the children (recursive) are selected.
The complete subtree is selected (the node and all of its children (recursive)).

A click on the selection marker for the following status transitions:

Background represents the children and children's children white, gray, black - none, do, all
Plunger in the middle represents the node itself - filled, or empty - selected or not selected

Consideration:

When selecting, the node itself is selected first and then (when clicking again) the entire subtree (if it did not previously contain a selected node) - careful selection.
A completely selected subtree can be deselected with a single click.
If other selections already exist in the subtree, these are not overwritten - a click only switches between the selection of the clicked node.
There could be the additional context menu commands
- Select all (regardless of the state in the subtree)
- Deselect all (regardless of the state in the subtree)
- 1, 2, 3,... Select levels.
