    1.54 +	 * 
    1.55 +	 * This constructor allows the use of setting page using only the editor resource.  Other combinations are also possible
    1.56 +	 *
    1.57 +	 * In all cases the number (if supplied i.e. <> 0 ) is used.

    1.60 +	 *			present				present				Both are used (but text & number overridden)
    1.61 +	 *			 = 0					present				Editor resource is used via SP resource (Effectively like the other constructor)
    1.62 +	 *			present				= 0					Default Avkon SP resource if used + this editor resource
    1.63 +	 *			 = 0					= 0					uses default resource for both SP and editor. This is OK if:
    1.64 +	 *	 i) control type is present, 
    1.65 +	 *  ii) a default resource exists ( OK for text, integer, date, time, duration )
    1.66 +	 *
    1.67 +	 * Note: THe first argument is a TDesC* (rather than TDesC&) because the other constructor
    1.68 +	 * cannot initialize such a member without allocation or having an internal dummy buffer.
    1.69 +	 *
    1.70 +	 * Rules for text and numbers: The rules are the same for both:  (non-zero length) text or number other 
    1.71 +	 * than EAknSettingPageNoOrdinalDisplayed if given in this constructor will not override resource 
    1.72 +	 * (unless that is zero length or EAknSettingPageNoOrdinalDisplayed).  Note, however, that text or number given via the 
    1.73 +	 * specific API for setting them, WILL override resource.
    1.74 +	 * It is assumed that number from resource is very rare.  Special text is somewhat more likely.
