One of My landlord's kids started using The GIMP the other day on a school provided netbook. Prior to trying to help Him with his project I never much thought about the fact that python plugins (unless written with a custom UI) do not scroll. Being a Linux user, Alt-Drag always worked just fine for me. But it did not for him. Thus I tackled gimpfu.

This is a drop in replacement for gimpfu, in fact it IS gimpfu with 6 new lines of code, and one line changed. (The curious can see the end of this post.)

Using this all python plugins begin with a size of 50% of your screen height, and a width equal to the data displayed + 44 pixels. The width won't be right on all machines however, as different operating systems and themes display scrollbars at different widths. None-the-less, almost all of the horizontal distance will be visible from the start, thus rendering any plugin usable from the get go without having to resize the window. (Although it can be fully resized if you choose to.) The "data entry" area of the plugin will scroll as needed using a traditional scroll bar. (If someone using the standard windows theme could give me a clue how much more width is needed, I can update this. Ditto for Macs)

Installing this plugin is a little different. It will work just fine installed into the standard user plugins folder (see next paragraph), but should be installed in place of the system version. On linux mint 17.1 this is at /usr/lib/gimp/2.0/python so probably the same for Ubuntu and other Debian derivatives as well. I'm not sure of this location on windows and macs. On linux the permissions need to be 644 (u+rw-x, g+r-wx, o+r-wx) with owner typically set to root:root.

A side note for those of you who run gimp from a command line. If it is installed to a user plugin folder, the following non-fatal errors will appear during gimp start up:This is completely ignorable, and is because GIMP is trying to import it as a plugin, and failing. Remember, this isn't an actual plugin, but a file to import into a plugin. Having it in this folder means it will override the one in the system folder, as it will be found first from within python during imports.

As for what changed, well changes were made in 2 spots, the first began as (line numbers added)and then became:
The second spot for changes was: became:
If anyone wants to make it be a wider starting size, simply change the "+ 44" on line 810 to a bigger number.

I think a mistake in annex (not the new file) ?

After making changes works well.
A great solution - it lacked me this.
Thanks Jazzon.

Python authors who make UIs that require scrolling should be taken out and shot(*). The script-fu authors have an excuse because they cannot do anything else to get parameters, but in Python you can use pyGTK to make more sensible UIs if needed.

(*) or sentenced to 6 months of Scheme coding, but given the choice...

ofnuts: I'll take shot .... and if schemers are the shooters, I'd like a blindfold...

Wallace: correct. The only changes made create the scroll effect, and only for python coded plugins.

MareroQ: Glad You like it! (Even You had to hand code it....)

CRAP! I zipped the wrong one! File in post one corrected to the NEW version

I thought that I would add an updated version of gimpfu for Gimp 2.10 users in case anyone else needs a scrolling dialog for any over-large python plug-in interfaces. The Gimp 2.8 version will display the filter dialog but it will not work when used in 2.10. This version has worked with all (Windows tested only I am afraid) versions so far.



If you have a portable version of Gimp 2.10 the location of the gimpfu file will depend on where you saved the portable. If you open the folder you should be able to click on the folders within to reach find the gimpfu and replace it using the instructions given below.

For Partha portables (substitute the 2.10.2 with whatever version number you have) it will probably be in something like:

Partha 2.10.2\Gimp-2.10\gimp\lib\gimp\2.0\python

For SamJ's versions there may be two optional locations to try (depending on 32 or 64 bit systems I assume). Once again find where your portable has been put and open the folders to drill down to the correct one. Either;

Gimp-2.10_Portable\lib\gimp\2.0\python

or

Gimp-2.10_Portable\32\lib\gimp\2.0\python

In my full version of Gimp 2.10.4, from gimp.org, the location I use is:

C:\Program Files\GIMP 2\32\lib\gimp\2.0\python

To copy and rename folders in this location you will need to provide/confirm Administrator priviledges when queried.

Instructions for replacing Gimpfu

Download and unzip the python file.

Copy my version (gimpfu_original_2pt10_ammended) into the same folder.
Rename the original gimpfu to something else (just in case) e.g. gimpfu_old.
Now rename my version as gimpfu.

You should now be good to go.

I'm sorry, but this sucks. Gimp is open source, but open source has rules. Gimp is licensed under the GPL, and by redistributing the code you agree to abide to the GPL requirements, and a key one is that if you make a derivative version, you must clearly identify it as your version:

To cite the GPL3 licence:



and I don't see anything like this in the code your provide.

Thank you Ofnuts for pointing this out. And I am more than very happy to comply with this - I shall add the required information at once and edit the post.

A courteous response Skinnyhouse, to a less than courteous post.

Thank you for your kind words TL.

I do think that Ofnuts has a number of extremely useful points to make in his follow up post and I value both his input and insight as a professional programmer. I have, personally, learnt a lot from his work and it must be extremely frustrating for him to witness the efforts of those, like myself, who battle with bits of code in order to get something working in Gimp.

I have to admit that I knew very little about licenses and stuff before this (obviously my own responsibility) and now I can understand the importance of documenting ownership, dating versions and modifications etc – hence the benefits of having someone around who works in the industry and to whom these things are so blindingly obvious.

I know that there is some information on script writing resources pinned to the ‘Gimp Scripts and Plugins’ section but perhaps some information about licences and modifications and their value could also be pinned there too. It might help others motivated to help fellow members in this time of transition from Gimp 2.8 to Gimp 2.10.

It is possible to change the theme of the scrolling interface to go with the gimp theme? I am using Gimp 2.10.10 Windows 64 Bit. I downloaded gimp from gimp.org

My Theme:


The Python Scrolling Interface:


I also tried Skinnyhouse's version of the gimpfu ammeded scrollbar and it crashed right away. I went back to jazzon's script. It works.. just not feeling the theme color since it doesn't match the theme I use.

It is possible for us to use the one that you made changes to, MareroQ?

Also is it possible to change the color in order for it to match the theme you're using? I'm using gimp 2.10.10 which I downloaded from gimp.org. OS I'm using is Windows 10 64 Bit.

Hi Mackenzieh.

The case with the scroll bar has been a bit complicated (different python versions) but the Jazzon recipe is still valid.
It is not complicated after all.
Copy the gimpfu.py file to a safe place and edit the original file (preferably in Notepad ++ 7.6.6:
https://notepad-plus-plus.org/download/v7.6.6.html ).
according to post # 1 (just look for spaces in the code's text).
Another (worse) option is to try the attached file (but without a guarantee of operation on your system - in my for Gimp 2.10 32bit works very well).

I will try the file first. I am not a coder but I will try it if the file doesn't go well. I have Gimp 2.10.10, Windows 10.. 64 bit.

Edit:
It works with all themes:
Dark:

Gray:

Light:

System:


I'm not sure if it works for themes other than the ones installed, but my guess is, it should.
