| class CEikFloatingPointEditor : public CAknNumericEdwin |
This class presents an editor modifying a real. The decimal place can occur anywhere. Exponential notation is allowed.
Validation, consisting of a check that the contents are parsable as a number (using TLex::Val()) and a range check, is carried out when PrepareForFocusLossL is called. Invalid contents cause a leave of that method.
Value() only returns a value corresponding reliably to the value in the editor after a non-leaving call to PrepareForFocusLossL.
