Question

I have a class that extends JFrame to make orders.
in the middle I have a button that opens a new window that is used to find an article.

What I need is:
When I click btnNewArticle, after searching new article, and confirm in new window, I will get as return article code.

Click btnNewArticle –> (open new window to find an article) –> confirm selection –>as return I get Article Code.

Is it possible?

Thanks

For me this principle has worked:

public class ArticleSearchDialog extends JDialog {

    public static ArticleId execute(Frame parent) {
        ArticleSearchDialog dialog = new ArticleSearchDialog(parent, true);
        dialog.setVisible(true);
        return dialog.getSelectedArticle();
    }

    private ArticleId getSelectedArticle() {
        return selectedArticle;
    }

    private void jbCancelActionPerformed(ActionEvent evt) {
        selectedArticle = null;
        setVisible(false);
        dispose();
    }

    private void jbOkActionPerformed(ActionEvent evt) {
        selectedArticle = ...; //TODO 
        setVisible(false);
        dispose();
    }        

    // All the rest of the dialog code.
}

Then the call gets really easy:

ArticleId articleId = ArticleSearchDialog.execute(this);
if (articleId != null) {
    //TODO
}
