Edited:

When I click on the START button of the GUI I would like to be executed the code in his section and close when finished or print an error message if there is one like from the Console.

I am faced with 2 problems that I have problem to solve:

  • Passing the paths I get from the GUI of the other 2 action buttons to the third action.
  • Displaying the error from the GUI if there is one (if it works fine I can simple exit from the program)

Here's what I did:

    1. Please no code in a link. If you have pertinent code, show it here. 2. I urge you not to try to merge a linear console program with an event-driven GUI. Better to change the Traduttore.java class to a new class, one that can be used in an event-driven way (or linear console way) and can act as a model for the GUI. Commented Dec 18, 2021 at 18:17
  • I tried initially to post it here but it is too long out of the bounds for stackoverflow. The code from the first part, I would like to show for completeness not knowing what might be useful to show and what not. As for doing it all in one class, I've tried that route and I'm still trying but I keep having constant problems. so having that part working fine like that I thought I'd just call it up in the GUI class instead of redoing everything.

  • You can add more code as long as you add a certain amount of text that fully explains your code and your problem. Make sure that the text that you add helps to clarify your code and your problem and is not "junk" text that some post to get around the code/text expected ratio. Best if you create and post a valid minimal reproducible example program as the code presented. Commented Dec 18, 2021 at 18:48
  • @AliasCartellano it would be a good workaround if i didn't need to get the paths from GUI Commented Dec 18, 2021 at 19:06
  • @HovercraftFullOfEels edited all the post since i'm near to have solved the first issue, it was related to all the library that i was using Commented Dec 18, 2021 at 19:19

What you need to do is make use of "dependency injection".

That is, you need to create some kind of "model" which can be shared amongst you Actions which provide the means to "set" the properties that they control and "get" the properties which they need.

Now, you could use multiple interfaces to further limit what each Action can do (because not all actions need access to all the functionality), but I'll leave that up to you.

Now start with one or more interfaces

public interface Model { public void setSourceFile(File file); public void setDestinationPath(File file); public File getSourceFile(); public File getDestinationPath(); }

Maybe reduce the code duplication by providing an abstract action which fills in some of the common features...

private abstract class ModelAction extends AbstractAction { private Model model; public ModelAction(Model model) { this.model = model; } public Model getModel() { return model; } }

And then fill in the required needs...

private class SwingAction_btnNewButton_1 extends ModelAction { public SwingAction_btnNewButton_1(Model model) { super(model); putValue(NAME, "..."); putValue(SHORT_DESCRIPTION, "Some short description"); } public void actionPerformed(ActionEvent e) { JFileChooser fileChooser1 = new JFileChooser(); fileChooser1.setCurrentDirectory(new File(".")); //seleziona solo cartelle fileChooser1.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); //prende i file da aprire 0 / 1 int risposta = fileChooser1.showOpenDialog(null); if (risposta == JFileChooser.APPROVE_OPTION) { getModel().setSourceFile(fileChooser1.getSelectedFile()); } } }

//JButton btnNewButton_1_2 private class SwingAction_btnNewButton_1_2 extends ModelAction {

 public SwingAction_btnNewButton_1_2(Model model) { super(model); putValue(NAME, "..."); putValue(SHORT_DESCRIPTION, "Some short description"); } public void actionPerformed(ActionEvent e) { JFileChooser fileChooser2 = new JFileChooser(); fileChooser2.setCurrentDirectory(new File(".")); //seleziona solo cartelle fileChooser2.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); //prende i file da aprire 0 / 1 int risposta = fileChooser2.showOpenDialog(null); if (risposta == JFileChooser.APPROVE_OPTION) { getModel().setDestinationPath(fileChooser2.getSelectedFile()); } } }

//JButton btnSalvaIn private class SwingAction_btnSalvaIn extends ModelAction {

 public SwingAction_btnSalvaIn() { putValue(NAME, "Save to :"); putValue(SHORT_DESCRIPTION, "Some short description"); } public void actionPerformed(ActionEvent e) { JFileChooser fileChooserSave = new JFileChooser(); fileChooserSave.setCurrentDirectory(new File(".")); //seleziona solo cartelle fileChooserSave.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); //prende i file da aprire 0 / 1 int risposta = fileChooserSave.showSaveDialog(null); if (risposta == JFileChooser.APPROVE_OPTION) { getModel().setDestinationPath(fileChooserSave.getSelectedFile()); } } } //button action start private class SwingAction_btnStart extends ModelAction { public SwingAction_btnStart(Model model) { super(model); putValue(NAME, "START"); putValue(SHORT_DESCRIPTION, "Some short description"); } public void actionPerformed(ActionEvent e) { File sourceFile = getModel().getSourceFile(); File destinationPath = getModel().getDestinationPath(); //button action code where to pass the 3 paths // 1) cartella 2) scopeCartella 3) scopeFinal } }

nb: I can't make heads or tails of your code so I'm guessing at what each Action is doing, so you'll need to fill out those details

null layouts

And because they are a complete pain in the ... code. null layout are a bad idea which are going to constantly come back and byte you. Instead, take the time and effort to learn how to make use of the layout functionality available in Swing.
