click btnnewarticle --> (open new window find article) --> confirm selection -->as return article code.

is possible?

thanks

for me 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();     }              // rest of dialog code. } 

then call gets easy:

articleid articleid = articlesearchdialog.execute(this); if (articleid != null) {     //todo }
