Adding rows to a JTable
I am creating a jTable. Initially it has no rows.If we click "add" button a new row will insert.Is it possible to do this in a jTable?
Update your underlying TableModel and fire the appropriate event. Or, if you use an extension of DefaultTableModel, use the addRow method.
Consult the table tutorial for more information.

Value Change Listener to JTextField
(14 answers)
Closed 5 years ago.
I have a Swing program that uses JTextField's text to draw a string in canvas. The problem is it only does so after the entire text in the JTextField has been entered. How can I change the text in GUI dynamically, meaning each character that is being typed or deleted in JTextField is immediately drawn or deleted in GUI? I've already implemented MVC and have a bunch of actionListeners. Just not sure on what I should use the action listener for this. Scanner? Could somebody please point me in the right direction? Thank you.
It's possible to use DocumentListener to reach the goal. The details is at Value Change Listener to JTextField
Changes like "insert", "remove" can be detected at the listener, no need to press Enter to trigger them.

In javaFx, Why do we need to call "getChildren()" when we add an element to a window?
(3 answers)
Closed 5 years ago.
For example if I were to add a line of code such as-
hbox.getChildren().add(calculateButton);
what significance does .getChildren hold and what happens if it not used in a program?
getChildren method is used to get the children components(such as checkboxes, buttons etc) in a container.
In your case, hBox is a container which can contain buttons, spinners etc. So getChildren lists the current components in hBox.
It is basically a list of components currently present in the container. By using add() you are adding a new component in that list.
