In DelphiVCL Library or Python in general, the following methods can be defined to emulate numeric objects. Methods corresponding to operations that are not supported by the particular kind of number implemented (e.g., bitwise operations for non-integral numbers) should be left undefined.
object.__add__(self, other)
object.__sub__(self, other)
object.__mul__(self…

In previous examples, we already use .Items several times (see Getting Started with DelphiVCL III: Overview of Commonly used VCL Components). We use it in ListBox, ComboBox, and RadioGroup. Items contain the strings that appear in the ListBox, ComboBox, and RadioGroup.
Use Items to add, insert, delete and move items. By default, the items in a list box are of type Strings. Use this item type to…
