* WIP: Add TreeTableSource * Improve expand/collapse * Render branch/tree properly * Simplify TreeTableSource to only allow one TreeView * Add TestTreeTableSource_BasicExpanding test * Add test combining checkbox and tree together * Move tree example into main TableEditor scenario (deleting TreeTableExample.cs) * Mouse support for expanding/collapsing branches * Make TreeTableSource work with CheckBoxTableSourceWrapperByObject<T> * Add tests for mouse expand/collapse * Improve quality of TableEditor scenario * Fix mouse expanding not refreshing screen * Fixed null reference when clicking in header lines * Add null checks to scenario now it can show trees as well as data tables * Switch to underscore prefix on private members * Remove accidentally committed file * Add setup/teardown to explicitly set driver checked/unchecked glyphs --------- Co-authored-by: Tig <tig@users.noreply.github.com>
