* In addition to using this macro (which you don't need to use,
|
|
* you can define the get_type() function directory if you wish)
|
|
* you also need to define the gobject type cast macros. For example,
|
|
* for the QofInstance type you would need to define the following
|
|
* macros:
|
|
*
|
|
* #define QOF_TYPE_INSTANCE (qof_instance_get_type ())
|
|
* #define QOF_INSTANCE(o) \
|
|
* (G_TYPE_CHECK_INSTANCE_CAST ((o), QOF_TYPE_INSTANCE, QofInstance))
|
|
* #define QOF_INSTANCE_CLASS(k) \
|
|
* (G_TYPE_CHECK_CLASS_CAST((k), QOF_TYPE_INSTANCE, QofInstanceClass))
|
|
* #define QOF_IS_INSTANCE(o) \
|
|
* (G_TYPE_CHECK_INSTANCE_TYPE ((o), QOF_TYPE_INSTANCE))
|
|
* #define QOF_IS_INSTANCE_CLASS(k) \
|
|
* (G_TYPE_CHECK_CLASS_TYPE ((k), QOF_TYPE_INSTANCE))
|
|
* #define QOF_INSTANCE_GET_CLASS(o) \
|
|
* (G_TYPE_INSTANCE_GET_CLASS ((o), QOF_TYPE_INSTANCE, QofInstanceClass))
