Method Detail

actionPerformed

public void actionPerformed(ActionEvent event)

Allow the user to select a single file, and attempt to use its contents to replace all currently stored Portfolio objects.

• If a file is not selected, then take no action.
• If a non-existing file is selected, inform the user and ask them to select something else.
• If an existing but non-readable file is selected, inform the user and ask them to select something else.

If the user attempts to import a second time, present the file selection GUI using the directory in which they showed interest during the first import. (This will often decrease the navigation burden on the user.)
