Hi, @Gaal-Dornik
Of course you can add header, divider and icon in to Popup dialog.
this is a simple example for how to add title, separator and icon:

import c4d

def main() -> None:
    bc = c4d.BaseContainer()
    bc.InsData(c4d.FIRST_POPUP_ID, "item01")
    bc.InsData(c4d.FIRST_POPUP_ID+1, "item02")
    
    # add a title
    bc.InsData(0, "This is Title")
    bc.InsData(c4d.FIRST_POPUP_ID+2, "item03")
    bc.InsData(c4d.FIRST_POPUP_ID+3, "item04")
    
    # add separator
    bc.InsData(0, "")
    bc.InsData(c4d.FIRST_POPUP_ID+4, "item05")
    
    # add icon for an item
    bc.InsData(c4d.FIRST_POPUP_ID+5, f"item06 &i{5140}&")
    bc.InsData(c4d.FIRST_POPUP_ID+6, "item07")
    
    res = c4d.gui.ShowPopupDialog(cd=None, bc=bc, x=500, y=500)
    

if __name__ == '__main__':
    main()

And the result is like this:

Hi @Gaal-Dornik

Yes, you can create just regular command with c4d.gui.ShowPopupDialog
Just like this:

import c4d

def main() -> None:
    
    menu = c4d.BaseContainer()
    # Add some commands
    menu.InsData(5159, "CMD")
    menu.InsData(1007455, "CMD")
    menu.InsData(1018544, "CMD")
    
    # Show the popup menu
    c4d.gui.ShowPopupDialog(cd=None, bc=menu, x=500, y=500)
        

if __name__ == '__main__':
    main()

And this is the result:

For more information about c4d.gui.ShowPopupDialog, you can go to This page.

And about your question：

How to create a radial (pie) menu?

I've done some research on this:

• Just using c4d.gui.ShowPopupDialog to create the radial menu. But I don't like the style of that. I want to highly customizable of UI creation methed.
• Use c4d.gui.GeUserArea. we can use c4d.gui.GeUserArea to draw anything we want. But unfortunately, we can't just keep the UI widgets and make the background Dialog disappear.
• Use third-party UI Library like PySide(PyQt), we can create any style of UI interface, but the problem is that Cinema 4D doesn't support third-party libraries, so we can't normally use PySide in Cinema 4D Python, While there are people in this thread who can use it, I think PySide is too big for a gadget like Radial Menu (it's fully 300MB in size).

That's it. If you have intrested or some ideas for that, please tell me.

Cheers~

Thanks so much for @Dunhou and other Boghma member to do this amazing things!

Hi @ferdinand ！
Sorry for late reply, and thank you very much for your detailed and thorough explanation, and for taking the time to explain the relationship between linear algebra and trigonometry in the context of computer graphics and transformations.
As a beginner, all I want to do here is to practice as much as I can with the knowledge I've learned, and I apologize if I didn't explain clearly.
Yes, in the code I want to implement is placing two tangent handle relative to the two input objects a and c.
Compared to calculating with trigonometric functions, your suggestion seems more straightforward and clear, and I never would have thought to use vectors to achieve this, I need to keep practicing.
I will take the time to review the thread you mentioned.
Thank you again for your support and guidance. Thank you very much for your insights!

Hi everyone!
I have recently been learning some basics of linear algebra.
In order to verify my learning results, I created a Bezier spline Generator with Python Generator.
But when I set the tangents of the spline, something confused me.
When I moved the point of the spline, the left and right handles of the tangent would switch positions, or would they flip 180 degrees? I don't quite understand what's going on here.

And there is my test code and Scene file:

import c4d
import math

def main() -> c4d.BaseObject:
    null = c4d.BaseObject(c4d.Onull)

    a = op.GetDown()
    b = a.GetNext()
    c = b.GetNext()

    obj = b.GetClone(0)
    obj[c4d.NULLOBJECT_RADIUS] = 5
    obj[c4d.ID_BASEOBJECT_USECOLOR] = 2
    obj[c4d.ID_BASEOBJECT_COLOR] = c4d.Vector(1,0,0)
    obj2 = obj.GetClone(0)
    obj2[c4d.ID_BASEOBJECT_COLOR] = c4d.Vector(0,1,0)

    a_pos_local = ~b.GetMg() * a.GetMg().off
    a_polar_angle = math.atan2(a_pos_local.y, a_pos_local.x)
    a_length = a_pos_local.GetLength()

    b_pos_local = ~b.GetMg() * c.GetMg().off
    b_polar_angle = math.atan2(b_pos_local.y, b_pos_local.x)
    b_length = b_pos_local.GetLength()

    polar = (a_polar_angle + b_polar_angle)/2 + (math.pi / 2)
    leng = (a_length + b_length)/2
    x = leng * math.cos(polar)
    y = leng * math.sin(polar)
    vec = c4d.Vector(x,y)


    move_vec1 =  vec.GetNormalized() * op[c4d.ID_USERDATA,1]
    m1 = ~op.GetMg() * b.GetMg() * c4d.utils.MatrixMove(move_vec1)
    m2 = ~op.GetMg() * b.GetMg() * c4d.utils.MatrixMove(-move_vec1)

    obj.SetMg(m1)
    obj2.SetMg(m2)

    obj.InsertUnder(null)
    obj2.InsertUnder(null)
    
    spline = c4d.SplineObject(3, c4d.SPLINETYPE_BEZIER)
    spline.SetPoint(0, a.GetMg().off)
    spline.SetPoint(1, b.GetMg().off)
    spline.SetPoint(2, c.GetMg().off)
    
    vl = ~b.GetMg() * obj.GetMg().off
    vr = ~b.GetMg() * obj2.GetMg().off
    spline.SetTangent(1, vl, vr)
    
    spline.InsertUnder(null)

    return null

tangent.c4d

Thanks for your explaination @ferdinand
Now I understand what's going on here.

Cheers!

This is my plugin , I promise I'm not reuse plugin id, and I can't use it, it will show that the plugin ID has been registered
But I get this: (It's a TagData Plugin, but I can get another Command-Type here.)

So many Object, Tool and Tag type plugins have a command type.

Hey @ferdinand ，
Thank you for your clarification.
What I meant by the difference is what will happen when users execute commands with the same ID but different types.
How do they differ in terms of their functionality?
For instance, if executes a Tool-type Cloud Tool and Command-type Cloud Tool, what would happen in each case?
and if they perform the same function, can I then avoid manually screening them?

Hi @ferdinand
I'm sorry I wasn't clear. Currently I'm using PySide to create my plugin, And my final goal is fully recreate the Command Manager Dialog, and Drag and Drop the Commands to my other UI widgets just for better experience.

I have created a user interface similar to a command manager, but I've noticed that some commands retrieved using the plugins.FilterPluginList() method are duplicated.
In my understanding, Plugin IDs are meant to be unique in Cinema 4D, but encountering duplicate command IDs has confused me.

For example, I get three "Cloud Tool" with same ID using plugins.FilterPluginList() but diffrent type (tool, command, node).
While I can manually filter them, but I think this complicates the workflow unnecessarily.
So I would like to know why commands with the same ID have different types, and what their differences are.

An my second question: How do I get the information in the plugin column in Command Manager?

In Cinema 4D, many commands share the same icon and name. I believe when users search for a command by its name, encountering multiple identical commands can be confusing. Therefore, additional information about the commands is needed to help users filter them effectively. In now , I can get the icon, name, shortcut key, help string of command, but I don't know how to get "the information in the plugin column in Command Manager" or the owner like you said.

Thanks for your reply
Cheers~

Hi Everyone!
Currently I'm recreating the Command Manager Dialog in Cinema4D, because I need to drag and drop these commands to other plase in my plugin.
And I have some questions:

• Is there a shortway to get all the commands in Command Mnager directly? because the plugins.FilterPluginList(PLUGINTYPE_ANY) give everything in cinema , it have some folders, and some commands are repeated, the plugin id is same but diffrent plugin type and diffrent info, some commands do not have names, I'm a little confused in this situation.

• if there are no shortway to get all commands in Command Manager, How do I get the information in the plugin column in Command Manager?
  

Thanks for your explanation @m_adam , Yes it's a CommandData plguin but no GeDialog.
Because of some limitations, I had to use PySide to create my plugin's special user interface.

Thank you @m_adam , I will try it later today!
Cheers!

Hi everyone!
I want my plugin to do different things on different Windows, similar to Commander in Cinema 4D.
So I try to get the current active window, such as; Object Manager, Material Manager, Node Editor, etc.
But I didn't find anything about this in the SDK documentation.
So is that possible to do that?
