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.

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.

Java swing Table transparency
It is not so easy to make a JTable background transparent. I want to see only the text content of my cells.
The table will be transparent if neither itself nor the cells are opaque:
table.setOpaque(false);
((DefaultTableCellRenderer)table.getDefaultRenderer(Object.class)).setOpaque(false);
If the table is in a ScrollPane, it is to make transparent as well:
scrollPane.setOpaque(false);
scrollPane.getViewport().setOpaque(false);
At least, you can remove the grid lines:
table.setShowGrid(false);
Quite a big work for a simply result...
