When initializing a pygimp plug-in derived from gimpplugin.plugin, only pass the plug-in's init() and quit() functions to gimp.main() if the plug-in actually implements them, instead of passing the default NOP versions. This avoids plug-ins that don't implement init() from being registered as having an init function, causing them to be run at each startup.

#
|
|
# This is a small wrapper that makes plugins look like an object class that
|
|
# you can derive to create your plugin. With this wrapper, you are pretty
|
|
# much responsible for doing everything (checking run_mode, gui, etc). If
|
|
# you want to write a quick plugin, you probably want the gimpfu module.
|
|
#
|
|
# A plugin using this module would look something like this:
|
|
#
|
|
# import gimp, gimpplugin
|
|
#
|
|
# pdb = gimp.pdb
|
|
#
|
|
# class myplugin(gimpplugin.plugin):
|
|
# def query(self):
|
|
# gimp.install_procedure("plug_in_mine", ...)
|
|
#
|
|
# def plug_in_mine(self, par1, par2, par3,...):
|
|
# do_something()
|
|
#
|
|
# if __name__ == '__main__':
|
|
# myplugin().start()
|
|
|
|
import gimp
|

|
|
class plugin:
|
|
def start(self):
|
|
# only pass the init()/quit() member functions to gimp.main() if the
|
|
# plug-in overrides them, to avoid the default NOP versions from being
|
|
# called unnecessarily. in particular, this avoids plug-ins that don't
|
|
# implement init() from being registered as having an init function,
|
|
# causing them to be run at each startup.
