How can I implement a directory selection dialog in GIMP using Python-Fu? I’m looking for a way to allow users to choose a directory when running a script. Any guidance on how to achieve this would be appreciated.

I’m diving into some scripting with Python-Fu in GIMP and hit a bump in the road that I could use some help with. I’ve been trying to figure out how to implement a directory selection dialog so that when users run my script, they can easily choose a directory instead of having it hardcoded.

It seems like a pretty handy feature for any script since people often want to work with different folders without changing the code every single time. I want to make the user experience as seamless as possible. But, here’s where I’m stuck. I’ve looked through the official GIMP docs, but they seem to skim over the GUI elements, and I haven’t found much about creating a dialog for directory selection specifically.

I’m familiar with creating basic dialogs for user input using the `gimpfu` module, but when it comes to allowing users to browse their file system for a folder, it’s a different story. Is there a simple way to invoke a file selection dialog that filters for directories only? I’ve seen some examples where people use file selectors, but those seem to allow file selection rather than folder selection.

What I’d really love is some sample code—or at least pointers on which functions to use. Are there specific functions or libraries in Python-Fu that handle this kind of task? Or maybe some workarounds you’ve found successful?

It’s important for my project because it involves processing images in bulk from specific folders, and I know being able to select a directory would make it much more user-friendly. Plus, I’m kind of excited about the prospect of learning how to extend GIMP’s functionality in this way! If anyone has tackled this before or has any resources to share, that would be super helpful. Thanks in advance!

    1. It sounds like you’re diving into an exciting area with Python-Fu in GIMP! I totally get the need for a directory selection dialog since hardcoding paths can be such a pain.

      To allow users to select directories, you can use the GTK file chooser dialog, which is part of the GIMP environment. Here’s a simple way to implement it:

          
import gimpfu
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk

def choose_directory():
    dialog = Gtk.FileChooserDialog(title="Select a Folder",
                                   action=Gtk.FileChooserAction.SELECT_FOLDER)

    dialog.add_button(Gtk.STOCK_CANCEL, Gtk.ResponseType.CANCEL)
    dialog.add_button(Gtk.STOCK_OPEN, Gtk.ResponseType.OK)

    response = dialog.run()

    if response == Gtk.ResponseType.OK:
        folder = dialog.get_filename()
        print("Folder selected: " + folder)  # Do something with the folder
    dialog.destroy()

def your_script_function(img, layer):
    choose_directory()
    # Continue with the rest of your script

register(
    "python_fu_your_script",
    "Your Script Description",
    "Your Script Help",
    "Your Name",
    "Your Name",
    "2023",
    "/Filters/Your Script",
    "*",
    [],
    your_script_function)

main()

      This code sets up a basic folder selection dialog. When the function `choose_directory` is called, it opens a dialog where users can select a folder. The chosen folder path can then be used further in your script.

      Just make sure you have GTK library installed and GIMP can access it. This should help streamline your workflow and hopefully enhance the user experience!

      Good luck with your project and have fun experimenting!

    2. To create a directory selection dialog in GIMP using Python-Fu, you can use the `gtk` or `gi` library depending on the version of GIMP you are working with. The following sample code illustrates how to create a simple directory selection dialog that allows users to browse and select a directory. After setting up the `gtk` environment, you can invoke a dialog that filters for directories. Here’s a basic example:

      import gimpfu
import gtk

def select_directory():
    dialog = gtk.FileChooserDialog("Select Directory",
                                    None,
                                    gtk.FILE_CHOOSER_ACTION_SELECT_FOLDER,
                                    (gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL,
                                     gtk.STOCK_OPEN, gtk.RESPONSE_OK))
    
    response = dialog.run()
    if response == gtk.RESPONSE_OK:
        directory = dialog.get_filename()
        print("Selected directory:", directory)
        # Add code here to process images in the selected directory
    dialog.destroy()

gimpfu.main()

      This code creates a dialog that prompts users to select a folder, allowing you to capture the chosen directory path for further processing. If you want to ensure the usage of GIMP’s existing event loop, consider integrating this dialog within your existing script’s context. You might also want to look into the `os` module to handle the file system or file iterators to process images in the selected directory efficiently. Make sure to check the latest GIMP documentation for any updates or changes in the GTK dialog functionalities. Tailoring your script to enhance user-friendliness through directory selection can significantly improve the workflow for users processing images in bulk.
