GIMP Python，切换所有可见或不可见的路径，如何？

Question

I'm trying to create a GIMP Python plug-in to toggle visibility of all paths in the image on or off. This is to more easily process images with lots of paths (>100+) instead of endless clicking in the paths dialog.

The GIMP Python documentation is not very helpful and I could only find the function set_component_visible. But when I try img.set_component_visible(v, False) or img.set_component_visible(v, 0) is gives this error:

TypeError: an integer is required

Here is the code I have got so far:

from gimpfu import *
import os

def select_paths_visible(img, layer, tog, apl, wc):

    # iterate all paths (internally called "vectors")
    for v in img.vectors:
        img.set_component_visible(v, 0) # <== TypeError on this line

# tell gimp about our plugin
register(
    "python_fu_select_paths_visible",
    "Toggle paths visible",
    "Toggle paths visible",
    "BdR",
    "BdR",
    "2017",
    "<Image>/Tools/Toggle paths visible", # menu path
    "",
    [
        (PF_RADIO, "p1", "Toggle paths:", 1, (("Invisible", 0), ("Visible", 1))),
        (PF_RADIO, "p2", "Apply to paths:", 1, (("All", 0), ("With name", 1))),
        (PF_TEXT, "p3", "Pathname contains:", "test")
    ],
    [],
    select_paths_visible
)

main()

My question is
1. should I use set_component_visible differently
2. is there a different function to toggle paths visibility on/off?
3. What is a good source for documentation on the GIMP Python functions

Answer 1

Simply:

for v in image.vectors:
    v.visible = False

1. set_component_visible() is about RGB channels and not paths (it seems to be the equivalent of clicking he visibility of the RGB channels in the Channels dialog)
2. gimp_vectors_set_visible() or change the attribute of the vector directly as done above
3. The Procedure Browser ( Browse... button in the Python-fu console) is quite efficient IMHO. In Python, the more often used calls have equivalents as object methods and attributes. Use dir(object) to list methods and attributes. You will find many things that have obvious equivalents as PDB functions. Attributes may be be R/W (as visible above) or just R/O (and should then be changed with a method or a PDB function).

If you need sample code, see these two scripts repositories: general scripts and paths-related scripts

PS: for you name criterion:

for v in image.vectors:
    if string in v.name:
        v.visible = False
