Setting jtable cell height same as jtextfield height?

Hello,

I'm trying to use my own StandardOneClickEditor which extends
DefaultCellEditor as a cell editor in a jtable.

====
public class StandardOneClickEditor
extends DefaultCellEditor{
public StandardOneClickEditor(){
super(new JTextField());
this.setClickCountToStart(1);
}
}
====

StandardOneClickEditor uses a JTextField as the editor component. When
i run the program and click on the cell the StandardOneClickEditor
appears with the jtextfield. No problem here.

But it seems that the cell height is a little to small for a
jtextfield with border. So i made a little function which makes all
cells in a jtable the same height as a standard jtextfield:

====
public FieldTable() {
super();
this.setRowHeight((int)new
JTextField().getPreferredSize().getHeight());
}
====

This seems like a nice working hack, but i'm wondering if this is the
right thing to do. Any ideas about this?

Regards,

JTable has a default row height of 16 pixels.
The brain dead part is that you have to adjust this by hand
using setRowHeight. If you use a different font or put a
custom component in the table the table does not get the
preferred size from the contents.

Seems resonable. It works.
You might want to put a sanity check in case some other JVMs/JREs dont
work the same. (Possible that empty textField might have default 0s).
eg (untested code)
public FieldTable()
{
super()
int rowHeight = (int)new JTextField().getPreferredSize().getHeight();
if (rowHeight >= 1) this.setRowHeight(rowHeight);
}

After browsing a little more at the given link i've come to the
conclusion that it really is a nice site. I'm wondering why google
didnt gave me that site. It's now on my desktop :-)
