Question

Hi I have a java GUI application which shows table and allow user to move column and resize them. The problem is that each time I exit and restart the application, column place and size are back to default. Is there a mean to keep it as what it was before exiting the application? any link to ref on the subject would be appreciated. thank you

I would record this info and store it using the Java Preferences API. Capture the resize using something like:

TableColumn col=table.getColumnModel().getTableColumn(colNumber);
col.addPropertyChangeListener(new PropertyChangeListener() {
   public void propertyChanged(PropertyChangeEvent e) {

      // has the column width changed ?
   }
});
