The SoQtObject class is the common superclass for all SoQt component classes.
The purpose of making this class the superclass of all SoQt device, component and viewer classes is to be able to do runtime type checking of the SoQt objects.
You can place the macro SOQT_OBJECT_HEADER(classname,parentname) within a class definition header for SoQt extension components to automatically provide the necessary definitions for setting up a runtime type system for your extension classes:
Then put the SOQT_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 SoQtObject. This is used for runtime type checking and "downward" casting.
Usage example:
|
static |
Initialize the type system of SoQtObject, all SoQt device classes and all SoQt components (including viewers).
|
static |
Sets up initialization for data common to all instances of this class, submitting necessary information to the internal SoQt type system.
SbBool SoQtObject::isOfType | ( | SoType | type | ) | const |
Returns TRUE
if the type of this object is either of the same type or inherited from type.
