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?

If the plugin is for public use, gimp.message() is a better solution
because it will display in a dialog box or in the Gimp message console 
depending on user preferences. You don't really need to drag in all the
GTK support just to display an error message.

On the other hand, I don't see how you pass a list of files to a
plugin.. If this is a batch script, things are a bit different, but then
there may be no UI at all, and the message would be better printed to
the console.
