Currently i have a JTextArea embedded in a table cell.  BUT i don't want the row height to be the height of the text area.  what i want to have happen is that when a user clicks into the given cell it expands (the text area, not the table row) similar to how combo box does.

what would be the best way to do this?

Oh, it sounds like you want to activate a pop-up when the cell is activated.  That would be my suggestion.  Let me try a talk-through first.  1. Create a new class (maybe a JDialog) that would handle the text entry (a get/set method, loose focus method for activating the close.), implement the TableCellEditor interface.  2. create an instance of that class and register it as a cell editor for that column.

public class MyTEdit extends JDialog implements TableCellEditor {...}
...
.
.
//in the table creation area
TableColumn textColumn = table.GetColumn("TextArea");
textColumn.setCellEditor(new MyTEdit());


That should roughly do it.  Gives you a little something to play with, but I hope that the idea is clear enough.

yeah, that's kind of how i was thinking i had to do it... i thought there might be a different way where i didn't have to use JDialog but rather just use JTextArea.

i'll leave this open for a while to see if anyone else has some input.

JComboBox uses a popup as well to display it's list when you click it.. It's about the only way to do what you want (that I can think of.)

ok, sorry for the delay, i was working on another issue.

Ok, i have it set up more or less as shown above...

is it possible to get rid of the "Java Applet Window" in the status bar of the JDialog? If not, are there any suggestions as to what I should do to work around it (i don't want it there)...

You'll need to sign your applet.

can anyone tell me how to get the damn location of the current table cell relative to the screen!!!

ie:
in my table cell i'm storing a JTextArea.

so in my getTableCellEditorComponent(...)
i do something like this:

JTextArea jta = (JTextArea) value;

jta.getX() returns 0
jta.getY() returns 0

jta.getLocationOnScreen().getX() returns error
"Component must be showing on the screen ..."

same for jta.getLocationOnScreen().getY()

i'm sure this isn't as difficult as i'm making it... i'm not all there this morning!
