TcxGeometryObject Class
The base class for persistent classes that store geometry-related information.
Declaration
TcxGeometryObject = class(
TcxLockablePersistent
)Remarks
This class extends its ancestor with members that allow you to do the following:
Save and restore geometry information (LoadFromStream and SaveToStream).
Scale geometry information by the specified numerator and denominator values (ChangeScale).
Respond to changes made to the stored geometric primitive (OnChange).
Do not use the TcxGeometryObject class directly. Use one of the following descendant classes instead:
- TcxMargin (stores a rectangular object’s margins, in pixels).
- TcxOffsets (stores pixel offsets of a visual object).
- TcxRect (stores the area and position (bounding rectangle) of a visual object).
- TdxPoint (stores a point in pixel coordinates).
- TcxSize (stores pixel dimensions of a visual object).
- TdxPointDoublePersistent (stores a point in double precision floating-point coordinates).
- TdxSizeFloat (stores dimensions of a visual object in double precision floating-point coordinates).
Note
A geometry object’s owner automatically calls the ChangeScale procedure in DPI-aware applications.
