[?] JTable cell/row selection: how to activate dialog?

I'm struggling with a similar problem.
How to find out the double clicked row??
There is no such method like in JList: locationToIndex(Point location)!!

Hi yongsing,

Thanks for your response ... it gets me quite a bit of the way to a solution.

but ...

As nil_dib comments, I also need to find out how to identify the specific double-clicked row.  I don't need to know which particular cell of the matrix, but I do have to be able to detect so I can put up a dialog related to that particular database record.

Thanks, and hope to get an expansion of your answer.

FWIW,

I found out about a Sun web-page that looks like it addresses my question, hopefully in depth.  I haven't evaluated it yet, but you can check ...

http://java.sun.com/docs/books/tutorial/uiswing/components/table.html

I'm leaving this question open for further comments, and will post a code snippet when and if a solution is forthcoming.

you can use the mouse listener then do this:

public void mouseClicked(MouseEvent me){
    if(me.getSource() instanceof JTable){
        JTable jt = (JTable)me.getSource();
        int selectedRow = jt.getSelectedRow();
        if(selectedRow == -1)
           return; //no row was selected
        else{
            doSomething();
         }

    }
}

Good Luck,

Kylar

Unbelievable!  A++++

"sqoms" answered with what appears to be a custom written ** COMPLETE ** program for my specific question.  All I had to do was compile and run it.  I'm an EE newbie, and I think this is gonna spoil me.

What was especially helpful was that the answer was pretty much the bare minimum, which is good.  My impression is that the JTable widget is perhaps the most complicated Swing component, and the books I looked at clutter up the issue with TableModels and CellRenderers, which thoroughly confuse this Swing newbie.

Just to make sure I understood the code, I did tweak it a little to a 3x4 table, as a 2x2 table can hide base-zero issues.  I also changed the column headings and cell contents to be zero-based to correspond to what showed up in the dialog:

  Object[][] cellData
     = {{"row0-col0", "row0-col1", "row0-col2" },
        {"row1-col0", "row1-col1", "row1-col2" },
        {"row2-col0", "row2-col1", "row2-col2" },
        {"row3-col0", "row3-col1", "row3-col2" }};

  String[] columnNames = {"col0", "col1", "col2"};

So maybe I should reduce the grade to an A+++ instead of an A++++ ???? :-)

The response from Kylar was also very good, and appears to have been sent prior to sqoms reply.  I've asked the EE Support people to give both replies an A, but I'm not sure if I went about that correctly.

you can post an empty question for Kylar and give him points.

glad that u found that helpful!

Hi sgoms,

I can see why your last 10 grades received have been
AAAAAAAAAA
and why you state in your member profile
"Solving problems gives me immense satisfaction!"

As a newbie, I only have a minimum number of points (200), which could go fast.  I felt kind of cheesy only offering 50 for that question, but ...

On the EE tips page, they state:

"If a member gets helpful solutions from several Experts, the process of posting comments allows that member to pull pieces from several comments to solve the issue at hand, and keep the question open for more proposed solutions. In this case, they may reward Expert points to multiple Experts by notifying Community Support. "

I tried this but I'm not clear if it will happen.  Plus I don't have enough points (yet) to be generous.  I think I spelled your id as sQoms rather than sGoms.  Sorry.

As a rank newbie, I'm unclear how I would go about doing your suggestion above: "post an empty question to Kylar and give him points."  Also, realize that not all of us have almost 52,000 points accumulated :-)

Hope to "encounter" you again as I take advantage of this site.  I've just started working remotely for a former company on a Linux+Java+mysql project, none of which I have much familiarity with. (as you can probably tell, at least from the initial Java question.  And I know even less about Linux and mysql)

It's a great opportunity, but I know I'm going to have lots of questions.

Down to 153 pts :-(

I also solved my problem like 'kylar' did.
BUT: CAN YOU BE SURE OF, THAT THE ROW IS SELECTED (getSelectedRow()) BEFORE THE DOUBLE CLICK METHOD (mouseClicked(MouseEvent e)) WILL BE CALLED!?
I believe there is mno garanty!
