I want to make a pie menu for Blender's toolbar, but I don't know the name of the icon

I wrote this code to create a pie menu for the toolbar.

class my_translate_piemenu(Menu):
bl_label = "Translate"
bl_idname = "my_translate_piemenu"  
def draw(self, context):
    layout = self.layout
    pie = layout.menu_pie()
    pie.operator("wm.tool_set_by_id", text = "Annotate").name = 'builtin.annotate'
    pie.operator("wm.tool_set_by_id", text = "Rotate").name = 'builtin.rotate'
    pie.operator("wm.tool_set_by_id", text = "Transform").name = 'builtin.transform'
    pie.operator("wm.tool_set_by_id", text = "Select Box").name = 'builtin.select_box'
    pie.operator("wm.tool_set_by_id", text = "Cursor").name = 'builtin.cursor'
    pie.operator("wm.tool_set_by_id", text = "Move").name = 'builtin.move'
    pie.operator("wm.tool_set_by_id", text = "Measure").name = 'builtin.measure'
    pie.operator("wm.tool_set_by_id", text = "Scale").name = 'builtin.scale'
    pie.separator()
    pie.separator()

Here is the resulting pie menu.

I would like to add an icon to this pie menu.

To add an icon, you need to write “icon = hoge” as the third argument of “pie.operator()”.
However, I don’t know the name of the toolbar icon.
I used an add-on called “Develolpment: Icon Viewer,” but it could not tell me the name of the icon in the toolbar.

Also, I searched Google and found similar questions to mine, but it didn’t tell me what I needed to do…

Can anyone tell me how to know the name of the toolbar icon when specifying it in Python code?

Try to search in the source file of that particular tool. Simply right-click on the icon and then choose edit source then check for the icon name.

You need to take a look at “WM_OT_toolbar_fallback_pie” as an example.
Check “draw_fallback_tool_items_for_pie_menu” in space_toolsystem_common.py,
you will need to use “icon_value” rather than “icon” argument.

A while ago, having that very problem, I made a cheat sheet

Cheat sheet for icons

I used it in one of my addons like this:

row.operator(
“object.bmapvis2_config”, text=“Provider”, icon=“WORLD_DATA”
).cmd = “providers”

HTH

Thank you for reply.

Right-clicking on the icon did not bring up the “Edit source” option.
a
This image shows the screen when you right-click on any icon.
I’m using Blender version 2.91.2, is it not possible to show the “Edit source”?
Or am I doing something wrong?

For a full list of icons accessible from blender use the addon included (Development: Icon Viewer)

to have the option “Edit Source”

Thanks for the reply.
I used “Development: Icon Viewer” to look at the icon list, but I couldn’t find the toolbar icon I wanted to use in it.
Does this mean that I can’t use the icons in the toolbar myself?

You should have all this checked in preferences/interface

Oh so you want to use the big color icons…
maybe this could help:

Thank you for your kind reply.

I looked at the site you gave me.
I found out that there are two types of icons in Blender and that the large size colored icons I’m trying to use are .dat files in [2.91\datafiles\icons].
But I couldn’t find anything more than that…

I tried right-clicking on the icon I want to use in the Blender toolbar and going to “Edit source” to see the code, but I’m not sure what code I need to write to use it in the pie menu.

See the function: _icon_value_from_icon_handle(icon_name)
In the file: scripts\startup\bl_ui\bl_ui\space_toolsystem_common.py

I modified the function to print the Tool Panel icon names to the system console as follows:
ops.transform.translate
ops.transform.rotate
ops.transform.resize
ops.transform.transform
ops.gpencil.draw
ops.view3d.ruler
ops.mesh.primitive_cube_add_gizmo
ops.generic.select_box
ops.generic.cursor

Thank you very much.
I’m really sorry for the delay in replying.

I looked at the _icon_value_from_icon_handle function in space_toolsystem_common.py.
By modifying it, do you mean that I should write the code you gave me somewhere in the _icon_value_from_icon_handle function?

If so, where should I put it?

I don’t recommend modifying the code in _icon_value_from_icon_handle, my intention was to direct you to where and how I retrieved the names of the icons that you are interested in so that you might examine the script in \2.93\scripts\startup\bl_ui\space_toolsystem_common.py to see how the icons are retrieved.

Hope this helps

Space_toolsystem_common.ToolSelectPanelHelper(). _icon_value_from_icon_handle(“ops.generic.select_box”)

↑By writing it like this, I was able to successfully get the toolbar icon!
Perhaps someone else told me about this a while ago, but I didn’t understand it at the time due to my lack of understanding.

Thank you very much!

I was able to resolve this question.
Thank you to everyone who helped me.

Sorry again when I said it was resolved.
I have one more question.

I don’t know how to check the icon_value of the icon in the toolbar.
I know “ops.generic.select_box” etc. because you wrote it in your reply earlier.
However, I don’t know the icon_value for other tools such as knife cut.

I looked at space_toolsystem_common.py and the icon_value for the toolbar is “icon_value = ToolSelectPanelHelper._icon_value_from_icon_handle(item.icon)”.
I found out that the icon_value of the toolbar is related to

However, I don’t know the specific name of the icon_value.
How can I find out the specific name of the icon_value?

Translated with www.DeepL.com/Translator (free version)

        print("idname: " + item.idname.split(".")[1] + "\nicon_value: " + str(icon_value))
        print("----------------------------------------"

I added the above to \2.93\scripts\startup\bl_ui\space_toolsystem_common.py: Line 689 to print out the following (Blender is in edit mode):

Thank you very much for your very kind help.
I have added the code you gave me to line 689 of space_toolsystem_common.py.

Then I got the same output in “Window > Toggle System Console” as you replied, and I was able to check the icon_value.

This is my first time using Python, and there are many things I don’t understand, so thank you very much for your kind help.

“ops.generic.select_box” - this matches the .dat file name,
see “…/2.93/datafiles/icons/” for all the others.

from bl_ui.space_toolsystem_common import ToolSelectPanelHelper
pie.operator(
    "wm.tool_set_by_id",
    text="Move",
    icon_value=ToolSelectPanelHelper._icon_value_from_icon_handle("ops.transform.translate"),
    ).name = 'builtin.move'

Thank you.
Now I see that the names of the icon_values, such as “ops.generic.select_box.dat” are
“D:\Program Files\blender-2.91(MyConfig)\2.91\datafiles\icons”
The name of the icon_value is the same as the file name in
Someone else had told me the same thing before, but I couldn’t figure it out, so…
