Get currently active image in python
Hello
I've been developing a plugin for my wife for her photography business. I'm using GTK and sqlite successfully in the plugin.
I'm at a part where I need to be able to find out the currently active
image (the image that is selected in gimp).
I have tried:
activeImage = gimp.image_list()[0]
but this only returns the most recently opened image, and not the currently selected image in gimp. Is there a way to get the currently selected image from gimp from within python?
thanks!

When you call the plugin's main function, you will automatically have access to the current image and drawable.
So something like this:
def my_plugin_function (image, drawable): print image
Will output the image object if gimp was started from a terminal. This is a bare-bones plugin that adds guides to the current image: http://registry.gimp.org/files/rule_of_thirds_guides.py

Thanks for the reply. I do realize that the current image and drawable is passed to the plugin when first opened. Perhaps I should explain further. I'm trying to build more of an extension that is opened just once, and updates as you move from image to image. (Its a time tracking window which stays open along side gimp). I wanted to make it so that a new instance of the plugin doesn't have to run for each image - just open it once, and it "knows" which image is currently active so that it can populate my sqlite database.
Is there a way to do this at in in gimp?
I'm not sure (reposting to list - be sure to 'reply-all' vs just 'reply').

No, there is not - at least no clean ways that I can think of. There
is nothing on the GIMP's API that marks an image as the
currently active image.(The "unclean way" I can think of would mean
to use GTK+ instrumentation for GUI debugging to be able to introspect
active
windows, and infere the active image from its title)
Another "unclean", but tidier, way would be to create a very simple script, with no parameters but "image and drawable" that would just signal your main plug-in when called - and you could bind it to a shortcut key and press it everytime you switch the active image.
To notify your mainplug-in you could use some file-system signaling mechanism, xmlrpc, or some gtk+ mechanism..
I'd use this second approach.

Ok thanks for the information. I think I'll file a feature request as well - I think this would be a great addition to the API
