Re: [Gimp-developer] When writing a GIMP Plugin using Python, can the Plugin display a GIMP based Dialog box informing the user if they haven't provided an argument?

When you write a Gimp plugin in Python, either you do your whole
interactive UI with PyGTK, or you let Gimp auto-generate a dialog to
collect parameters from the user before calling you. Of course the
second solution is a bit less user-friendly(*) but in many scripts,
doing the whole UI would represent the larger and most complex part of
the code.

(*) though not as bad as it looks, you can normally expect passed
image/layers/files/colors to exist since they have been specified using
specific dialogs.
