Detailed Description

Base class for a panel in the PrefsDialog. Classes derived from this class include BatchPrefs, DirectoriesPrefs, GUIPrefs, KeyConfigPrefs, QualityPrefs, SpectrumPrefs and ThemePrefs.

The interface works like this: Each panel in the preferences dialog must derive from PrefsPanel. You must override Apply() with code to validate fields (returning false if any are bad), updating the global preferences object gPrefs, and instructing the applicable parts of the program to re-read the preference options.

To actually add the new panel, edit the PrefsDialog constructor to append the panel to its list of panels.
