Enumeration Type Documentation

ChangeFlag

enum ChangeFlag : uint8_t

Flags indicating the types of modifications an object has undergone. These flags can be combined using bitwise OR to represent multiple changes simultaneously.

gom.h

Since

1.0, Jan 2026, sl

Enumerator
Properties	Simple property changes (e.g. values).
Structure	Structural changes (e.g. hierarchy).
Geometry	Geometric changes (e.g. mesh).

eDataType

enum class eDataType

strong

Available data types.

PropertyTypeKey.h

Since

1.0, Jan 2025, sl

Enumerator
xsString	String data type.
xsLong	Long integer data type (64 bit).
xsInt	Integer data type (32 bit).
xsDouble	Double precision floating point data type (64 bit).
xsFloat	Single precision floating point data type (32 bit).
xsBoolean	Boolean data type (true/false).
xsDate	Date data type (YYYY-MM-DD).
xsDateTime	Date with time data type (ISO 8601).
xsID	ID data type.
xsIDREF	ID Reference data type.
xsAnyURI	Any URI data type.
xsObject	Non-XML Schema data type, handles JSON objects/arrays.

eObjectStatus

enum eObjectStatus

Object status.

Since

1.0, Jan 2025, sl

Enumerator
None	No status.
Visible	Object is visible.
Selected	Object is selected.
Wired	Object is shown in wireframe mode.
Locked	Object is locked and cannot be modified.

FormulaType

enum class FormulaType

strong

gom.h

Since

PersistenceStatus

enum class PersistenceStatus : uint32_t

strong

gom.h

Since

1.0, Jan 2026, sl

Note

: do not change order of value, see isDirty()

Enumerator
Saved	clean
Restored	clean
Changed	dirty
Imported	dirty // todo: check if needed
New	dirty

PropertyTypeAddResult

enum class PropertyTypeAddResult

strong

gom.enums.h

PropertyTypeFlag

enum PropertyTypeFlag

Flags for property types, stored at key. Avoids hash look-up in property type store.

Since

TreeModelType

enum class TreeModelType : uint8_t

strong

Identifies type of a tree model.

Could be Objects, SmartSets or Viewpoints.

Since

1.0, Jan 2026, sl
