[Qt-interest] Checkimg for dirty table model

[Petric Frank]

Hello,

i access a SQL table (Postgres, MySQL) via a QSqlTableModel instance. The edit 
strategy is set to "OnManualSubmit". This can not be changed.
The code looks basically like this:

--------------------------------- cut -----------------------------------
 QSqlTableModel *table = new ...;

 table->setEditStrategy (QSqlTableModel::OnManualSubmit);

...
 do the changes (via the GUI, ...)
...

 bool dirty = false;

  for (int row = 0; row < table->rowCount (); ++row)
    for (int column = 0; column < table->columnCount (); ++column)
      dirty = dirty || table->isDirty (table->index (row, column));

  if (dirty)
   ... (for example update a timestamp somewhere else)
--------------------------------- cut -----------------------------------

Do i really have to iterate through all rows and columns to find a changed (and 
not committed) field?

The method "isDirty" indicates that QSqlTableModel already maintains a dirty 
list. Is there a possibility to obtain this dirty list - for example - as a 
list QModelIndex items of changed fields directly ?

Any hints ?
