drag and drop to jcomboBox

[Bumsys]

I want to drag and drop from jtree to jcomboBox. But when I try to
drop the string to jcomboBox. It needs that the popup menu appears and
the items will have the possibility to be selected?
How to do so?

I want to drag and drop from [JTree] to [JComboBox]. But when I try
to drop the string [on the JComboBox,] the popup menu appears and the
items will have the possibility to be selected?
How to do so?

This seems to be an odd user interface choice. Why can't the
TreeSelectionListener's valueChanged() method communicate the choice to
the JComboBox?
