Hi Everyone！
I want to Draw HUD in the viewport using CommandData Plugin. And i put my 'draw' function in to CommandData.GetState(self, doc)
but nothing happend in the viewport.
And the code like this:

import c4d


_Plugin_id = 20230616
_Plugin_name = "Command_Test"


class Command(c4d.plugins.CommandData):

    def __init__(self):
        self.a = False

    def Execute(self, doc):
        if self.a:
            self.a = False
        else:
            self.a = True
        print(self.a)

        return True

    def GetState(self, doc):
        if self.a:
            print(123)
            bd = doc.GetActiveBaseDraw()
            bd.SetMatrix_Screen()
            bd.DrawHUDText(50,50, "Test HUD")
            
            return c4d.CMD_VALUE | c4d.CMD_ENABLED
        else:
            return c4d.CMD_ENABLED

if __name__ == '__main__':
    c4d.plugins.RegisterCommandPlugin(id=_Plugin_id, str=_Plugin_name, 
                                info=0, icon=None, help='', dat=Command())

And there have another problem: you can see the "print(123)" in the GetState
method for testing, when i click my plugin, cinema4d can print correctly and continuosly in the console, but if i move my mouse to the viewport or click somewhere (like refreshing maybe), the cinema4d has been stucking.
I don't know if I'm wrong or misunderstood something

Hi @m_adam I am using Windows 10

I get a solution:
1.Create a material and insert it
2.EventAdd()
3.delete the material
code like this:

mat = c4d.Material(5703)
doc.InsertMaterial(mat)
c4d.EventAdd()
mat.Remove()

But this is not the correct way

There is a problem;
When i try to add some object in the scene and add c4d.EventAdd() , the object added correctly and viewport is refreshed but nothing happed in Object Manager, i need to click some button to refresh the object manager.

import c4d

def main() -> None:
    doc.InsertObject(c4d.BaseObject(c4d.Onull))
    c4d.EventAdd()

if __name__ == '__main__':
    main()

Is that BUG or something changed ?
Oh, i used Cinema 4D 2023.2.1 version.

Hi @ferdinand , I get it ! Thanks again to your reply!

@ferdinand
I mean i Get the Object Data using BaseList2D.GetData() and SetDatato another object, it's only change the parameter of "Object" Tab in Attributes Manager.
Hera is a exmaple:

from typing import Optional
import c4d

doc: c4d.documents.BaseDocument  # The active document
op: Optional[c4d.BaseObject]  # The active object, None if unselected

def main() -> None:
    new = doc.GetFirstObject()
    old = new.GetNext()
    
    old.SetData(new.GetData())
    
    c4d.EventAdd()

if __name__ == '__main__':
    main()

Before run the script

After run the script

As you can see, the object name, visibilitys and display color is not changed by SetData

Hi @ferdinand , thanks to your reply.
There is another quession; the basic property (like Name, Viewport visibility, Enabled, e.t.c) of object is not in the data container? I mean the c4d.BaseContainer returned by c4d.BaseList2D.GetData()

@dunhou
Cool man ! That's what i want !
I actually thought about traverse everything in the scene, but I felt it would be a waste. for example, if there were a lot of objects in the scene, so I think if there was another way to do that. But based on your post, that's the only way to do.
Anyway , thank you and @ferdinand

Hi plugincafe~
I want to get the object newly added in to current scene in my Dialog plugin and update something in my dialog.

For example:
Add something in the scene(like a null object), how do i get this object? and how to get this Message?

I find c4d.EVMSG_CHANGE in SDK and i can get some document changed message in CoreMessage. But I don't know what to do next.

@manuel
Cool ! Thank you ~

Hi everyone~
How did i create and get redshift light groups with python ?

@ferdinand
Wow~ Thank you so much bro

Hello everyone~
I have a GeDialogwindow now. and i want to close it when my mouse click in anywhare.
I can get the mouse click event in GeDialog.Message(), but it's just work inside of dialog.
So i think maybe i need to get the global input event . But i can't find any method in SDK.
How do i do that?

@m_adam
OK~ Thank you so much!

Hi guys!
I want to get the shader preview image , but i can't find any method in Python SDK.

So the question is :
is there have some tricks to get shader preview image ?

Another question is :
Is that posible to change Material Preview size before i use BaseMaterial.GetPreview() ?
Because i see the material preview image size is 90*90, it's small to me.

@fwilleke80
Yes, it's a solution. But it's can not to orbiting the scene or transforming the model.
I think i need to make a desktop application, and make sure the window always on top.
However, this will lead to more work for me.
And thanks to your reply!

@ferdinand
Hi!
Actually, i developed a simple model viewer using PyOpenGL and GLFW(for the window).
And i don't know if i can use CINEMA 4D VIEWPORT(replace the GLFW) to show my own OpenGL things.
So , clearly i need a dockable opengl window. is that possible?

hello everyone!
is that posible to attach an OpenGL window to Cinema 4D GUI using python?
if posible , how can i do that?

@ferdinand
Wow! you perfectly solved my problem!
Thank you! :beers:

Hi! plugincafe~
I try to get an image from website, And ShowBitmap() in C4D python.
This is my simple code:

import c4d
from c4d import gui, bitmaps

def main():
    img = "https://images.pexels.com/photos/10204089/pexels-photo-10204089.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500"
    bmp = bitmaps.BaseBitmap()
    a,b = bmp.InitWith(img)
    print(a,b)
    if a == c4d.IMAGERESULT_OK:
        bitmaps.ShowBitmap(bmp)
    bmp.FlushAll()
    
# Execute main()
if __name__=='__main__':
    main()

Sometimes it can ShowBitmap() correctly like this:

Sometimes it's can show bitmap but the image is not loaded correctly:

And sometimes it's faild! And the InitWith() result is -6
Is there have some right way to show an image from the URL?
