 /*

 TO DO:

 (1) Optional popup-help for each item, and an optional Help button
   for dialog.

 (2) Align Ok, Cancel, Help buttons properly.

 (3) Consider retrieving the rectangle on the panel that can be
 drawn into (where the value listbox is) and giving an example
 of editing graphically. May be too fancy.

 (4) Deriveable types for wxPropertyValue => may need to reorganise
 wxPropertyValue to use inheritance rather than present all-types-in-one
 scheme.

 (5) Optional popup panel for value list, perhaps.

 (6) Floating point checking routine still crashes with Floating
 point error for zany input.

 (7) Property sheet with choice (or listbox) to select alternative
 sheets... multiple views per panel, only one active. For this
 we really need a wxChoice that can be dynamically set: XView
 may be a problem; Motif?

 (8) More example validators, e.g. colour selector.
