Inheritance¶

Description¶

TNumericField is an abstract class which overrides some of the methods of TField to handle numerical data. It also introduces or publishes a couple of properties that are only relevant in the case of numerical data, such as TNumericField.DisplayFormat and TNumericField.EditFormat.

Since TNumericField is an abstract class, it must never be instantiated directly. Instead one of the descendent classes should be created.

Properties¶

Member	Visibility	Description
Alignment read only	published	Alignment of the field.
DisplayFormat	published	Format string for display of numerical data.
EditFormat	published	Format string for editing of numerical data.
