    Default Receive only first mouse-click, looking for double click

    Using swing jTable (named resultTbl), I want to have double click select the current row. The canonical suggestion is essentially to add a mouse listener
           resultTbl.addMouseListener(new java.awt.event.MouseAdapter() {
                public void mouseClicked(java.awt.event.MouseEvent evt) {
                    resultTblMouseClicked(evt);
                }
            });
    pointing to
       private void resultTblMouseClicked(java.awt.event.MouseEvent evt) {                                       
             if (evt.getClickCount() == 2 && !evt.isConsumed()) {
                evt.consume();
               /* perform select action */
            }
        }
    Much trial (both with and without the evt.consume() line and lots of printlns) has proven to me that this code sees one mouse click but never a second one. What can I do to get the second click?

    Thanks!

    Can you post a small, complete program for testing?
    Include the debug print statements that show when a mouse, press, release and click were received.

    I rather doubt it. I should have mentioned that Netbeans is the framework for this is program, and I don't think it's possible for Netbeans to create a small enough program to post. I'll give it a try when I get a chance [later today or tomorrow: life gets in the way], and maybe put the program into a dropbox file -- or is there a generally accepted repository for placing such programs (similar to the golang playground)?

    That is interesting.
    Strip out everything but a component that can receive a mouse click and display it. Add the listener.
    It shouldn't be over 50 lines.

    I don't care to download code from 3rd party sites.

    I started to create a sample, but for a jForm containing an empty jTable Netbeans generates over 100 lines of code. Now what should I do? I could continue trying to create an example, but it'd be uncomfortably long.

    An sample program does not need a JTable. Just a frame and maybe a JPanel and a listener should be enough.

    Default Re: Receive only first mouse-click, looking for double click

    I finally found the answer: disable the default editing caused by double clicking in a column of a jTable. Then, the MouseListener added as in the original post does work.

    Details -- two parts:

    1) Embedded in the solutions to a query about how to make a jTable non-editable at
    https://stackoverflow.com/questions/...e-non-editable
    is the comment
    "This is also the solution for making double click events work correctly with JTable. A double click is normally consumed by a cell as it goes into edit mode, and this will keep a cell from doing that and instead send the double click to the JTable itself. Thanks for the solution, Nelson! – " Mar 15 '12 at 15:39

    Ah ha! And how to prevent editing of a jTable in Netbeans?

    2) Answer is at
    https://stackoverflow.com/questions/...edit-in-jtable
    Specifically, "Well on netbeans you can right click on the table and click on table contents, then you go to the column tab and uncheck the "Editable" checkbox." I would add that this should be done for each column.

    So, problem solved.
