    I have a few object and tag plugins. Is it possible to change the icon through python?

    similar to how the annotation tag has the option "Color Icon".

    to change the icon of an object dynamically you have to react to the MSG_GETCUSTOMICON message in Message(). The data is a dictionary:

         if type == c4d.MSG_GETCUSTOMICON:  
              data['bmp'] = c4d.bitmaps.InitResourceBitmap(c4d.IDM_SELECTALL)  
              data['w'] = data['bmp'].GetBw()  
              data['h'] = data['bmp'].GetBh()  
              data['filled'] = True  

    best wishes,

    Ahh okay. I see the data. Now i tried:

    data['bmp'] = myCustomBitmap

    It doesn't update it. But if I do a test and write:


    it shows what i drawn. How can I update the objects icon after i assign it?

    don't forget to set 'filled' to true. Also make sure your bitmap "exists" after you assign it and is not destroyed by the garbage collection.

    One more thing. Where would the ideal location for the bitmap be so it isn't 'garbage collected'? Would the icon location best be suited in the init?

    Basically, I have an image icon with Alpha. I want to draw a color layer behind it and have it only show on the alpha of the main icon. I've seen some multi-layer bitmap in the API. Is that the way to go?

    if the icon is different for each object or tag you could store the bitmap as a member variable of your plugin class.

    Best wishes,
