Reordering columns in table view

Message 1 in thread

Hi

I'm trying to adjust the positions of columns in a table view linked
to a SqlRelationalTableModel. I want to be able to add an additional
column containing static data and also reorder the columns in the view
differently to the sequence the fields that are returned from the
select query.

I can successfully remove the primary key field using removeColumn(0),
but when I try and insert a column using insetColumn(2), whilst I
correctly get an extra column in the table view all the data after the
insert is shifted 2 columns to the right (and I therefore also lose
the data from the final field).

i.e. originally:

col1        col2        col3        col4
data1     data2     data3      data4

after insertColumn(2):

col1        col2       newcol        col3        col4
data1     data2                                         data3


So my 2 questions are:

1. Am I able to reorder the columns to appear in a different sequence
to that which is returned in the result set for the select query?
(I've looked at altering the select query but can't see a call on the
api to do this)

2. Why when I insert a column does the data shift 2 columns right rather than 1?

Hi

Have you noticed QHeaderView::moveSection()? The horizontal header
view is accessible via QTableView::horizontalHeader().
