Question

I am making an autocomplete project(just like Google). I have a jtextfield in my frame and whenever I type something to that field, a JWindow will appear below the textfield and that window is coming from another class.

Now the problem is how could I make the window always appear below the textfield whenever I drag the frame?

Any help would be much appreciated.. Thanks…

Answer 1

for manually set Location on the screen, you have to define something as private Point location; and getLocation from desired JComponent, don’t forget dealyed show for Show Top-Level Container into invokeLater();

for example

public void showWindow() {   
    window.setVisible(false);
    location = myTextField.getLocationOnScreen();
    int x = location.x;
    int y = location.y;
    window.setLocation(x - 20, y - 20);
    Runnable doRun = new Runnable() {

         @Override
         public void run() {
             window.setVisible(true);
         }
    };
    SwingUtilities.invokeLater(doRun);
 }
