How to Create Double-Click Event on a JTable
in Swing?
I have created a basic application with buttons, combo boxes a
JTable with a JScrollPane and want to have a double-click event on
my JTable which opens an "Edit Detail" screen that pulls up the
record's data and allows data to be filled in and then saved.
Here is how to set up a double-click event that opens a new
form:
1) First set up Mouse Listener on your JTable:
myJTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount() == 2) {
JTable target = (JTable)e.getSource();
int row = target.getSelectedRow();
int column = target.getSelectedColumn();
// do some action
}
}
});
This will give you the row and column that was
double clicked.
2) You can then use this to get the value of that row's ID and open
a new form and populate it with this record's data. Here is how you
would open a new form
JFrame newFrame = new JFrame();
newFrame.setTitle("Detail Screen");
newFrame.setVisible(true);
