Is there a way to utilize GimpPreview (or live preview window) api in a Python plugin? I can't find any tutorials or plugins using it and most resources are several years old.

This is not a solution - but maybe some direction.
Probably the only plugin (py) displays the image in your window is: GimpPublishr by Jayesh Salvi.
http://code.google.com/p/altcanvas/wiki/GimpPublishr

I'm not a programmer- can anyone look at the code?

The Annex - Image_in_python.py ( fragment of plugin GimpPublishr ).
In Gimp menu: File - > Image in plugin python
It does not do anything - just displays the image (without scaling and not every type of file).

Does anyone have an idea how to add (in gdkpixbuf.py) proper behavior scale ?

Can it be useful for something beyond the additional preview ?

I saw an idea garagecoder:

Question for GC:
wxwidgets can be used as a preview for each file Python?
Can I ask for more information (for beginners on this issue)?

Hi MareroQ
I'm not sure if I understand your question correctly, but I think you're asking if it's possible to have a preview window in a gimp python plugin. I think it's always been possible using a C wrapper, but according to this thread it should be possible directly from python now:

http://forum.meetthegimp.org/index.php?topic=87.0

I'm afraid it's not something I know a lot about, you could definitely write a C wrapper to do it but that's not something I'll be working on for now. If anything GTK will be what you need (not wxwidgets) to interface with.

*edit* there are some things I'm working on, documentation of gmic with wxwidgets and possibly a python wrapper for gmic (which I have already tested at a basic level). But don't hold your breath waiting!

This could be your revolution for Gimp Python.
(Unfortunately, my options are limited by the lack of a good knowledge of the English language).
Can you put the code somewhere (and instructions) on how you obtain GCTool

Hah I knew it would be dangerous to show it so early
I made it as a quick and dirty test of gmiclib with wxwidgets. The code is ugly. I'm not even a c++ programmer. But... once I have it to a reasonable state the code will be released, along with docs on the gmic wiki (which is the main reason for creating it).

Anyway back to your python question now that you got me interested, I had a look at the python script and I see "import gtk.gdk" and "import gtk" so basically the plugin is creating it's own GUI using a gtk python module. Beyond that I can't help without spending a lot of time learning python... hmm I'm so easily distracted

I've tried a number of times to get this working with no success. Possibly a more experienced python coder might have better luck than I.

Does somebody have a link to a recent version of "gimpui" python module? Perhaps just looking at the defs/classes in that would shed some light. Anyway I'm out of my depth here so I'll leave it to some flyby expert (I hope!).

For a beginner is not consolation
experienced programmer (Rob'A) has the same problem - with an image in Python for GIMP plugin - a much-needed solution - any idea on weight in gold

OK well if it is something a few people want, I'll look into it tomorrow. If it starts taking me days I won't be doing it though, so no promises!

"Tomorrow Never Dies".
Apparently, time is money –when ?

Relax, just a couple things I have to do to get started (learn python, learn how to create a gimp python script) so it's not going to be immediate

OK you're probably not going to like this answer
Preview doesn't seem to be implemented for "normal" gimp python plugins i.e. using gimpui module. I searched through all the modules and even the C wrappers. You would have to create the window from scratch using python gtk module instead (as the example you gave does), which for a non-programmer is not easy - and there's no way I can give a demonstration without spending a lot of time learning it.

@ RobA - I'd like to know which classes/defs you attempted to use! I noticed PF_DISPLAY isn't functional but I think it's to do with opening a new display which you can do with gimp.display() anyway.
