Yes What I am trying to say in my previous mail is this:
L1 L2 L3 L4
TF1 TF2 TF3 TF4 Add
When "Add" is clicked, becomes this:
(No label here the above label remains for this....)
TF5 TF6 TF7 TF8 Add
TF9 TF10 TF11 TF12 Add
and so on....
i.e.

You should be able to work out how to change my example that added
columns and make it add rows instead.

Which would be more conventional.
Hi
The conventional approach is the one I looked at and it is what se=
ems
more desirable ... However I tried experimenting with your program to
change the addColumn to the addRow method
private void addRows () {
constraints.gridx=fields.size();
constraints.gridy = 0;
panel.add(new JLabel(labelText), constraints); // I took this out
because I didn't want the labels to appear repeatedly when user
clicks ..
JTextField field = new JTextField(6);
JTextField field1 = new JTextField(6);
JTextField field2 = new JTextField(6);
constraints.gridy = 1;
constraints.gridy=1;
You need to increment gridy once for the new row.
You need to adjust gridx for each field.
panel.add(field, constraints);
panel.add(field1, constraints);
panel.add(field2, constraints);
fields.add(field); // so we can later retrieve content
fields.add(field1);
fields.add(field2);
Maybe you should consider a for loop involving an integer variable x?
y++;
constraints.gridy = y;
for(x=0, x<3, x++) {
constraints.gridx = x;
JTextField f = new JTextField(6);
panel.add(f);
fields.add(f);
}
I suspect you don't really need the extra variables x and y, you could
just operate on constraints.gridx and .gridy directly. But it seemed
clearer to have x and y.
Perhaps fields should be JTextField[][] instead of List<JTextField>?
panel.revalidate(); // redo layout for extra column
}
However the problem is that it still keeps adding one textfield thoug=
h
columnwise and not rowwise...Besides I removed the InputDialog as tha=
t
was not needed for repeated and new labels in the main program (Th=
e
actionevent method)
I couldn't figure why it kept on adding columnwise and not rows ??
constraints.gridx and .gridy set the x,y position of the component:
0,0 1,0 2,0 3,0
0,1 1,1 2,1 3,1
0,2 1,2 2,2 3,2
etc

Somehow I got it to display rowwise (i.e) adding dynamic textfields .
Here is the sample code. However is it possible to decrement by
clicking add One Row Above like I may not need a textfield when I have
fill the information desired....(i.e) the last textfield added
disappears and the row count of textfields is decremented......How?
Also I couldn't figure a way to make the buttons align automatically
when Add More Fields adds one textfield columnwise... Instead it would
be nice to have the two buttons aligbn themselves to the right when
one textfield is added columnwise?? I tried looking for a similar pack
property like resizing the frame when textfield is added columnwise
