Handling a TableColumn width change at the *end* of the resize

Question

Hi all.
I have a table with AUTO_RESIZE_OFF where the user can resize the columns. I want to store off the column sizes in a file so that the next time they open the app they get the same sizes. (Yes, I could use Preferences for this, but on Windows this results in data in the registry, and we want the files to be more visible and in a format users can see.)
I can of course do this:
addPropertyChangeListener(new PropertyChangeListener() {
    public void propertyChange(PropertyChangeEvent event) {
        if ("width".equals(event.getPropertyName())) {
            saveToFile();
    });The problem is that as the user is dragging the column divider, I get 1 to 50 of these events, and each individual one results in saving the whole file again. :-(
Is there a "proper" way out of this, or should I just use a Timer to save the columns a second after I stop getting events?

Answer 1

Some people seem to misunderstand the word "general". A general solution solves it in all cases. If it doesn't solve it in all cases then it's not general, it's specific and solves it only for the assumptions made.Your the one who doesn't understand "general". It was a general solution.
"Generally" speaking when you have an application with multiple tables, the tables contain different information so the sizing of the columns will be different for every table. So changing the size of one table does not "generally" change the size of all other tables in the application
So if you have a special requirement then you should specify it.
Also, good to see that the forum mods are deleting the retaliation but not the original attack it was in response to. GJ guys. There was no original attack. There was no name calling. The point of the response was to get you to specify requirements so we don't waste time giving a "general solution" when a "specifc solution" is required.
