After having dealt intensively with GIMP and the creation of Python plugins, I present my plugin "HN: Draw arror" / "HN: Pfeil zeichnen" in different language versions.
You can see the appearance of the user interface in the miniature views. Thanks to "ofnuts" for his help.Version maintenance:
2018-11-22 First version of the plugin, that I have been developing since the end of Oktober 2018.
..
2023-08-27 Improvements/bug fixes:
At arrow type "Dimensioning with auxiliary lines", the "Filling type of arrowhead" setting was only applied to the first arrowhead, but not to the second arrowhead.
Some code fixes for later migration from Python 2 to Python 3.
2023-10-07 Improvements/bug fixes:
Added new arrow style "Coordinate axis (path segment, with markers, triangle head)".
Storage of presets has been completely reworked so that the path can also be stored. Attention: Tool presets created before this version, cannot longer be used!
2023-10-15 Improvements/bug fixes:
When naming the tool presets, all characters ~“#%&*:<>?/\{|}ÄÖÜäöüß are converted to _.
Reworked the "Coordinate Axis" arrow so that axes/markers are meaningful and logical.
Attention: The new library is necessary!

Tested with:
GIMP 2.10.34 (Revision 2) installed on Windows 10, Debian Linux and Manjaro Linux.

Installation description:
Descriptions in English and German for installing the plug-in and the associated library module on Windows 10, Debian Linux and Manjaro Linux.

Download plug-in, library (module), documentation and installation description:
Downloads (DON'T FORGET THE LIBRARY) In the base directory you will find an English and German installation description!

Important:
As from version 2020-04-15, the plugin will consist of two parts. The plugin "HN-Pfeil-zeichnen_YYYY-MM-DD.zip" and a library module "HN_Bibliothek_YYYY-MM-DD.zip".
Therefore, please ALWAYS install or update the plug-in and the library module together!

The library module is also used by the other plug-in I created "HN-Draw-shape" for creating paths and drawing shapes.
If you are interested in this plugin too, just have a look at the topic "HN-Draw-shape: Create paths draw shapes simultaneously and easily".

Tips for quick starters:
- Unzip "HN-Pfeil-zeichnen_YYYY-MM-DD.zip" into the private "plug-ins" folder and "HN_Bibliothek_YYYY-MM-DD.zip" in the private "modules" folder.
- Please read the user manual "Plug-in HN-Draw-arrow.pdf" for detailed installation and user instructions!
- For information on contents of the download folder, please read the file "!LiesMich+ReadMe.txt"!

Finally, I would have the following wishes:
1. In computer science, the principle "No program without errors" applies. So if you find a bug in my plug-in, please don't complain, but describe the bug in as much detail as possible and let me know.
2. English is not my native language. If you have any suggestions for improvements to the interface, help, messages, or anything else, please let me know as well.

alright another scripter! yeh!

You should look into Python dictionaries, your code could be much simpler (long sequences of if/elif).

Hello Ofnuts, thank you for the very big "help". In my world, real help looks a little different! To give an advice and refer only to a literature is not helpful. Really helpful would be to list a range of code from the script and present a possible solution.

For instance:



Something similar can be done around line 519, keeping parameters of functions as a dictionary of tuples.

Hello Ofnuts, thank you for your help. I could simplify a lot. Can you look at lines 641 through 649? Is it possible to integrate these definitions into the "pfeilDaten" at line 55?

The code in German makes things complicated for me. Another simplication:



And then where you use you "pfeilTypen" you can just use "pfeilDaten.keys()" or even just "pfeilDaten" when you iterate: "for aktStil in pfeilDaten"

Yes, but it is a bit more complicated. Lines 641-649 are in a method scope and use instance methods that are already bound to an instance, and you cannot do that where you define pfeilDaten at global scope. What you can do however is store unbound methods in pfeilDaten: "dialogFenster.zeichne...." and then use pfeilDaten[pfeilGewaehlt][3](self).

Speaking of pfeilDaten, you should look into replacing the plain tuples by named tuples. They work the same way, but in addition to using indices to access items, you can also use names, so instead of "pfeilDaten[pfeilGewaehlt][3](self)" you can use "pfeilDaten[pfeilGewaehlt].funkt(self)".

Learn something every day. Looking at your code and the configuration of unbound methods I wondered how such dynamically selected method could be used in UI callbacks (that require the method to be bound to some instance, for instance "self.callbackmethod"). It appears that you can do it, see https://stackoverflow.com/questions/101 ... od#1015405

For more convenience, I've created the ability to create, delete and load tool presets in the plugin.

Hi,

I would like to give your plugin a try; I am hoping that my lack of German won't be a barrier.

How do I install the plugin so that it reads the English language XML file?

My first attempt was to copy the plugin and the folder "locale" into my plug in directory. The plugin shows correctly in the Filters folder, but it is in German. I deleted the German XML file and that did not change anything.

Thanks!

The windows of the plugin were programmed with "GimpUI", so that the surface looks like in GIMP.

Appearance of the surface, download and installation, see the beginning of the topic!

I didn't see anything in the first post that would render the windows in English rather than in German; there is an announcement of an English-language version but nothing else.

When I installed, it's all in German. The EN XML file is in the folder along with the German XML version.

What Language is selected under "Edit -> Preferences -> Interface"?

Hi Herbie.

Your plugin has many advantages (the most important for me is: a large number of possible settings, the ease of adding translations to other languages, saving presets).
However bothers a very large window size - can you add bookmarks? (or version without instructions - because the plugin is intuitive to use - and it is enough to get acquainted once).
Optional: change the default language to English - but a different one according to the user's choice?

ps. No information: if this is a GPL licensed plugin?

At the suggestion of GimpChat member "MareroQ", I have created a user interface with and without instructions to create an arrow.
Please read my short, unfinished English description!

Standard user interface with instruction at top:

User interface without instruction at top:


Appearance of the surface, download and installation, see the beginning of the topic!

Thank You for the very quick implementation of my request/suggestion.
Very interesting guide Plugin HN-Draw-arrow.pdf(en) - let me know when it will be finished.

I will give here Your clue how to change the interface's appearance
Interface without instructions:
line 85 mitHilfeImFenster = False replace to mitHilfeImFenster = True.

Note, how to change the appearance of the user interface.

Interface without instructions:
line 85 "mitHilfeImFenster = True" replace to "mitHilfeImFenster = False".[/quote]

"mitHilfeImFenster" is equivalent to "withHelpInWindow".

News:
Since 28.06.2019 there is a Polish translation for the user interface. Thanks to Marek (MareroQ).
Since 05.07.2019 errors in the visibility test of the shaft disc are no longer available.
Since 13.07.2019 the curved arrow is calculated with system routines and is thus faster than before.
Since 13.07.2019 a documentation is available in German and also in English. Because my English is not very good, I am very grateful for suggestions!

Hi Herbert.

Thanks for the sysematic improvement of the plugin.

I have a problem - your plugin does not work (does not register in the menu) when using Python MSC (e.g. Gimp 2.10.18 Partha which uses Python 2.7.5 MSC v.1500 64 bit).
I use Python 2.7.16 MSC v.1500 64 bit and the same problem.
For versions from gimp.org and Portable Samj which uses Python 2.7.17 GCC 64 bit everything works as expected.
This is surprising to me because Python MSC is much better with extended Gimp plugins than Python GCC.
Any tip on how to solve this problem?

edit: The update from 23-03-2020 solved the problem.
Thank you.
