Autocomplete in jTextfield - adapt class

Question

I was able to find here a code for autocomplete in a jTextfield. As I am new to programming, I have tried to adapt this code to use in Jtextfields of other classes I have but I haven’t been able to.

I tried to put this part of the code in my jTextfield action but it says that the Autosuggestor class is not published and so I can’t use it in my package:

  private void fActionPerformed(java.awt.event.ActionEvent evt) {                                  
_global.AutoSuggestor autoSuggestor = new _global.AutoSuggestor(f, frame, null, Color.WHITE.brighter(), Color.BLUE, Color.RED, 0.75f) {
        @Override
        boolean wordTyped(String typedWord) {

            //create list for dictionary this in your case might be done via calling a method which queries db and returns results as arraylist
            ArrayList<String> words = new ArrayList<>();
            words.add("hello");
            words.add("heritage");
            words.add("happiness");
            words.add("goodbye");
            words.add("cruel");
            words.add("car");
            words.add("war");
            words.add("will");
            words.add("world");
            words.add("wall");


            setDictionary(words);
            //addToDictionary("bye");//adds a single word

            return super.wordTyped(typedWord);//now call super to check for any matches against newest dictionary
        }
    };        

}

I have tried to make it public in the Test class which is the one that works with autocomplete but without success. Any hints where to start adjusting this autocomplete to my textFields?

Maybe go through the constructor the textField and the Word List? But how to then adapt in my code?

Answer 1

To answer your question:

I’d like to know where I position the list of suggestions, because it is showing me very much on the textField.

You can make that class change:

AutoSuggestor

In the method:

showPopUpWindow 

On this code line:

autoSuggestionPopUpWindow.setMinimumSize(new Dimension(textField.getWidth(), 30));
