How to have the back command in InteractionDialog

[P5music]

I have a method call to set the back command in my utility dialogs, in a special class with static methods.

Now I have to use InteractionDialog instead of Dialog but I do not know how to implement  this kind of line

if (cancellable) alertDialog.setBackCommand(backCommand);

Thanks in advance

Use setBackCommand on the form. Install a command to the back action. In its actionPerformed check if you have an interaction dialog to dispose and dispose that. If not go to the previous form.

Do you mean something like this?

public static void openMyDialog(Form form, other parameters)

{

final InteractionDialog myDialog=new InteractionDialog();

...

Command oldBackCommand=form.getBackCommand();

        Command backCommand=new Command("Back") {

            @Override

            public void actionPerformed(ActionEvent evt) {

                form.setBackCommand(oldBackCommand);

                myDialog.dispose();

            }

        };

        form.setBackCommand(backCommand);

...

}       

Is it safe?

That looks reasonable.
