I have a big problem. I have an application with many buttons and windows. On one of this windows (which extends Dialog class) a have a textField. I want to set it's value from another class B. If in class B I write tf.setText("test") and on the next line I write System.out.println(tf.getText) "test" is displayed, but in the textField the value doesn't change.
Cross-posting can frustrate anyone who tries to help you only to find out later that the same answer was given hours ago in a cross-posted thread. No one likes wasting their time, especially a volunteer. The polite thing to do would be to not do this, but if you feel that you absolutely must, to at least provide links in both cross-posts to each other.
