TcxPointDoubleBasedGeometryObject Class

The base class for classes that implement points in double precision floating-point coordinates.

Declaration

TcxPointDoubleBasedGeometryObject = class(
    TcxGeometryObject
)

Remarks

This class extends its ancestor with members that allow you to do the following:

• Compare geometry information to its stored initial state (IsDefault).

• Compare geometry information to a point (IsEqual).

• Identify if stored values are zeros (IsEmpty).

• Restore the initial geometry information (Reset).

Do not use the TcxPointDoubleBasedGeometryObject class directly. Use one of the following descendant classes instead:

• TdxPointDoublePersistent (stores a point in double precision floating-point coordinates).
• TdxSizeFloat (stores dimensions of a visual object in double precision floating-point coordinates).
