Java Swing将工具提示显示为消息对话框

Question

Is it possible in Java Swing to show message box using tooltip item. I need to show tooltip not only when a mouse hovers some component but also when I choose specific item in context menu of this component when tooltips are turned off.

You can use PopupFactory to show your popup message

    final Popup p = PopupFactory.getSharedInstance().getPopup(myComponent, new JLabel("Here is my popup!"), x, y);
    p.show();
    // create a timer to hide the popup later
    Timer t = new Timer(5000, new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            p.hide();

        }
    });
    t.setRepeats(false);
    t.start();

where myComponent - is the component for which popup must be shown

x, y - coordinates of popup.
