For the Modifier by Type addon i need a better way to recreate a enum property menu.
Some Hints how to do that? 4x enum in 1x enum?

If you want to replicate the layout, modifiers are listed in the same order in rna.
import bpy
# Categories start on these modifiers
mods = ('DATA_TRANSFER', 'ARRAY', 'ARMATURE', 'CLOTH')
# Rna enum items are listed in same order as menu.
op = bpy.ops.object.modifier_add
enum_rna = op.get_rna_type().properties['type'].enum_items
mdict = {"Modify": [], "Generate": [], "Deform": [], "Simulate": []}
for item, cat in zip(mods, mdict):
for mod in enum_rna[enum_rna.find(item):]:
mod_id = mod.identifier
# Delimit at next item in mods
if mod_id != item and mod_id in mods[mods.index(item):]:
break
mdict[cat].append((mod_id, mod.name, mod.icon))
# There's an invalid entry called Surface at the end of "Simulate"
# category. It's a duplicate of Simple Deform so we remove it.
if mdict["Simulate"] and mdict["Simulate"][-1][0] == "SURFACE":
del mdict["Simulate"][-1]
class MODIFIER_MT_add_modifier(bpy.types.Menu):
bl_label = ""
def draw(self, context):
layout = self.layout
split = layout.split()
for cat, mods in mdict.items():
col = split.column()
col.label(text=cat)
for id_, name, icon in mods:
col.operator("object.modifier_add", text=name, icon=icon).type = id_
if __name__ == "__main__":
bpy.utils.register_class(MODIFIER_MT_add_modifier)
bpy.ops.wm.call_menu(name="MODIFIER_MT_add_modifier")

Wow that is great!
I’m not so deep with blender RNA and I don’t know where I could have found it!
Thank you to figure that out!
