No, ttreeitemedit.selecteditems returns the items of the selected cells
of the grid. ttreelistitem.getselectednodes returns nodes where
tlistitem.selected = true (tlistitem.state ns_selected is set).
In order to set the selected state by GUI set
ttreeitemedit.itemlist.options no_checkbox and set tlistitem.state
ns_checkbox for nodes which should show a checkbox, see attachment with
[ns_checkbox,ns_showchildchecked] and ttreeitemedit.itemlist.options
[no_checkbox,no_updatechildchecked].
ttreelistitem.getcheckednodes() returns an array of the checked nodes.
Another option is to set ttreeitemedit.itemlist.options
no_cellitemselect which updates ns_selected by the cell selection state.
