Change Icon Color parameter

chuanzhen

hi,
I use script to create bone and insert it to document, set it Icon Color=Display Color,Why does the Icon Color parameter of the object turn to Custom when I click on it.

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected object in `doc`. Can be `None`.

def main() -> None:
    for i in range(2):
        obj = c4d.BaseObject(c4d.Ojoint)
        obj[c4d.ID_BASELIST_ICON_COLORIZE_MODE] = 2
        obj[c4d.ID_BASEOBJECT_USECOLOR] = 2
        obj[c4d.ID_BASEOBJECT_COLOR] = c4d.Vector()

        obj.SetName(str(i))
        doc.InsertObject(obj)
    c4d.EventAdd()


if __name__ == '__main__':
    main()

Thanks for any help!

Hello chuanzhen,
I tried this, you're right, it's strange, but curiously if a value is assigned to the color it manages to be created with the defined color without the need for interaction, this is a possible solution, even so I would like to know what could be happening.

@JH23 Thanks for your help,this is indeed a solution.
For existing objects in Object Manager, using this code is effective, but creating a new object and setting it up yields a different result, which is confusing.

@chuanzhen said in Change Icon Color parameter:

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected object in `doc`. Can be `None`.

def main() -> None:
    for i in range(2):
        obj = c4d.BaseObject(c4d.Ojoint)
        obj[c4d.ID_BASELIST_ICON_COLORIZE_MODE] = 2
        obj[c4d.ID_BASEOBJECT_USECOLOR] = 2
        obj[c4d.ID_BASEOBJECT_COLOR] = c4d.Vector()

        obj.SetName(str(i))
        doc.InsertObject(obj)
    c4d.EventAdd()


if __name__ == '__main__':
    main()

Hi @chuanzhen,
I wanted to say that it is confusing that it fails to create an automatic color when defining the use of icons with custom colors, I suspect a reason why this happens but I am not at all sure, I am still happy that this solution works for you, even so I would like to know if this is something planned or some kind of bug.

Hi @chuanzhen,

The "Display Color" value of the "Icon Color" attribute is a dynamic value (comparing to "None" and "Custom" being static values), this was explained in the related thread: Python Documentation - Icon Color. This is the reason why it requires special handling, namely (as Manuel explained in the related thread: Simple Organisational Structure Generation Script), one needs to send a c4d.MSG_GETCUSTOMICON_SETTINGS message to the object to properly set this attribute. Please check the example code snippet that shows its usage.

Cheers,
Ilia

Example code, showing the usage of the c4d.MSG_GETCUSTOMICON_SETTINGS message:

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected object in `doc`. Can be `None`.

def main() -> None:
    obj = c4d.BaseObject(c4d.Ojoint)
    
    # Configure object display color attribute
    obj[c4d.ID_BASEOBJECT_USECOLOR] = c4d.ID_BASEOBJECT_USECOLOR_ALWAYS
    obj[c4d.ID_BASEOBJECT_COLOR] = c4d.Vector(1, 0, 1)

    # Configure object icon color attribute
    settings = c4d.CustomIconSettings()
    settings._colorMode = 2
    obj.Message(c4d.MSG_GETCUSTOMICON_SETTINGS, {'setting': settings})
    obj[c4d.ID_BASELIST_ICON_COLORIZE_MODE] = c4d.ID_BASELIST_ICON_COLORIZE_MODE_CUSTOM + 1

    obj.SetName("Magenta Joint")
    doc.InsertObject(obj)


if __name__ == '__main__':
    main()
    c4d.EventAdd()
