The SoXtObject class is the common superclass for all SoXt component classes.
The purpose of making this class the superclass of all SoXt device, component and viewer classes is to be able to do runtime type checking of the SoXt objects.
You can place the macro SOXT_OBJECT_HEADER(classname,parentname) within a class definition header for SoXt extension components to automatically provide the necessary definitions for setting up a runtime type system for your extension classes:
Then put the SOXT_OBJECT_SOURCE(classname) macro within the actual implementation source code file to include the necessary code for the runtime type system:
See also the documentation of the SoType class in Coin or Inventor.

static |
This static method returns the SoType object associated with objects of this class.
|
pure virtual |
Returns the type identification of an object derived from a class inheriting SoXtObject. This is used for runtime type checking and "downward" casting.
Usage example:
|
static |
Initialize the type system of SoXtObject, all SoXt device classes and all SoXt components (including viewers).
|
static |
Sets up initialization for data common to all instances of this class, submitting necessary information to the internal SoXt type system.
SbBool SoXtObject::isOfType | ( | SoType | type | ) | const |
Returns TRUE
if the type of this object is either of the same type or inherited from type.
