As the title stated i want to show tooltip when the user press up and down keys in combo box, Please any hint ..... Regarding to problem

and what did you tried, nothing complicated

1) (for fun, but safiest way) get popup from JComboBox.getComponent[0]

2) or directly add JList with pre-definned popup for its Items

I have added tool tip in form of List, and Pop function pop combo box , i dont want to pop combo box, i want to pop its tool tip.....

that same if you extract popup and then JList from JComboBox or (hardiest) to set JToolTip to the JComboBoc(JList);
