|
|
* @query_procedures: This method can be overridden by all plug-ins to
|
|
* return a newly allocated #GList of allocated strings naming the
|
|
* procedures registered by this plug-in. See documentation of
|
|
* #GimpPlugInClass.init_procedures() for differences.
|
|
* @init_procedures: This method can be overridden by all plug-ins to
|
|
* return a newly allocated #GList of allocated strings naming
|
|
* procedures registered by this plug-in.
|
|
* It is different from #GimpPlugInClass.query_procedures() in that
|
|
* init happens at every startup, whereas query happens only once in
|
|
* the life of a plug-in (right after installation or update). Hence
|
|
* #GimpPlugInClass.init_procedures() typically returns procedures
|
|
* dependent to runtime conditions (such as the presence of a
|
|
* third-party tool), whereas #GimpPlugInClass.query_procedures()
|
|
* would usually return procedures that are always available
|
|
* unconditionally.
|
|
* Most of the time, you only want to override
|
|
* #GimpPlugInClass.query_procedures() and leave
|
|
* #GimpPlugInClass.init_procedures() untouched.
|
|
* @create_procedure: This method must be overridden by all plug-ins
|
|
* and return a newly allocated #GimpProcedure named @name. It will
|
|
* be called for every @name as returned by
|
|
* #GimpPlugInClass.query_procedures() and
|
|
* #GimpPlugInClass.init_procedures() so care must be taken to
|
|
* handle them all.
|
|
* Upon procedure registration, #GimpPlugInClass.create_procedure()
|
|
* will be called in the order of the lists returned by
|
|
* #GimpPlugInClass.query_procedures() and
|
|
* #GimpPlugInClass.init_procedures()
|
|
* @quit: This method can be overridden by a plug-in which needs to
|
|
* perform some actions upon quitting.
|
|
*
|
|
* A class which every plug-in should subclass, while overriding
|
|
* #GimpPlugInClass.query_procedures() and/or
|
|
* #GimpPlugInClass.init_procedures(), as well as
|
|
* #GimpPlugInClass.create_procedure().
