Its true, i havent thought of the implications of what it means to
switch rows. Should references pointing to cell A1 remain pointing to
A1, when the content of A1 is "traded" for the content of B1? What
should the references follow?
But apart from that, the way to exchange two rows is I believe indeed
achieved most easily by a combination of the insert_row(), move_row(),
delete_row() methods.
Doing this in Python would be a nice exercise.
Thanks again for the feedback.

Here is what I wrote a few years ago to move column "C" to the
location of "A", as Niklas suggests. :-)
Sub Main
oSheet = ThisComponent.getCurrentController().getActiveSheet()
Move_Column(oSheet, "C", "A")
End Sub
Sub Move_Column(oSheet, sFrom, sTo)
cFrom = oSheet.getColumns().getByName(sFrom)
cTo = oSheet.getColumns().getByName(sTo)
oSheet.getColumns.insertByIndex(cTo.getRangeAddress().StartColumn, 1)
iToBeRemoved = cFrom.getRangeAddress().StartColumn
cTo = oSheet.getColumns().getByName(sTo)
oSheet.moveRange(cTo.getCellByPosition(0, 0).getCellAddress(),
cFrom.getRangeAddress())
oSheet.getColumns.removeByIndex(iToBeRemoved, 1)
End Sub
That is for a single column, but could be enhanced to deal with
multiple columns and rows.
Anyone who are interested in writing code for the following behavior?
1. choose a certain cell or cells.
2. Ctrl-Alt-Arrow Key (up, down, left, or right)
3. the the column(s) or row(s) that accommodates the selected cells
goes around as directed by the arrow key.
That could be similar behavior as Writer does with Ctrl-Alt-Up or Down
arrow key to move the paragraph up or down as if the paragraph is
freely swimming on the document.
Thanks in advance,

Thanks for the feedback, indeed it makes intuitively sense to check
out that part of the API.
The simplest way of defining the rows to exchange (that I can think
of right now) would be to just to select two rows in the spreadsheet.
If more or less than two rows are selected, this would cause an
exception.

I was thinking, would it be possible to implement some kind of row-row
exchange button in Calc? Of course, the same could apply to
column-column exchange.
It depends on the desired behavior of that button. Probably it can
be a combination of "insert rows", "move cells" and "delete rows".
These are all available via API, so it can be implemented as an
extension. How do you want to select the rows to exchange?
Anyway, would be cool if someone could point me out to some part of
the
code where one might start looking at this.
See http://wiki.services.openoffice.org/wiki/Extensions_development
for general information about extension development.
