Jtable row/cell/column selection issue

    Hi all,

    I think we're tied in our underwear here...

    (a) My JTable is set to allow cell selection, so I have these
    statements when I set up the table:

    fpeTable.setRowSelectionAllowed(false);
    fpeTable.setColumnSelectionAllowed(false);
    fpeTable.setCellSelectionEnabled(true);

    things work as advertised.

    (b) I also have a mouse listener for column header clicks that
    programatically selects all the cells in the column. The cells are
    shown with a different background, as wanted.

    (c) Now I would like to simulate the effect of
    setRowSelectionAllowed(true) in that I'd like to color all the row when
    any cell is clicked (selected). So I created a custom renderer that
    sets the background of the JLabel component to a different color when a
    cell is selected. This works too. However, now if I click on the column
    header, the entire table's background is changed. Clearly not what I
    want, and I understand why it's happening (because of the custom
    renderer sees all cells in the column being selected by the mouse
    listener).

    How does one fix this? The behavior we want is:

    If a cell is selected via a click, simulate selection with the custom
    renderer; however, if the cells are selected from the column header
    click, just select the column. Can this be done?

    Thanks!

    get the click x,y location and use the JTable columnAtPoint(Point
    point) or rowAtPoint(Point point) methods to check whether the click
    was done within the table. If the click is outside the table, the
    above methods will return -1.

    If it is outside, do not do the default select all columns in a row
    logic

    Yes, this did the trick. I was looking in the wrong places, like is
    there a way to alter the selection modes...

    Thanks!
