Hello!
Another question translate C++-Code to Python... ;)
I want to display a Bitmap in the Attribute Manager from a Tag-Plugin.
In C++ Message() was called with type==MSG_DESCRIPTION_GETBITMAP and the BITMAPBUTTON-id, but in Python it isn't? And what is the equivalent from GeData in GetDParameter() in Python?
Anyone have a Code-snippet how it works for me?
I would be glad,
Cheers,
Mark.

I guess it's like you do in C++ use BitmapButtonStruct.
https://developers.maxon.net/docs/Cinema4DPythonSDK/html/modules/c4d/CustomDataType/BitmapButtonStruct/index.html#c4d.BitmapButtonStruct
(btw there are some errors in the python sdk, then take a look at the c++ one)
https://developers.maxon.net/docs/Cinema4DCPPSDK/html/class_bitmap_button_struct.html
And just follow this thread https://plugincafe.maxon.net/topic/2006/1355_customdata-and-gui-messaging&PID=4936#4936
In python we don't have GeData since a variable is not type dependant.
So you can do
a = int()
b = "hey"
a = b #now a will be a string with value "hey"
Hope it's help

Hi Mark,
I'm afraid MSG_DESCRIPTION_GETBITMAP can't be handled inside NodeData.Message() currently.
With the Python API, the implementation of NodeData.GetDParameter() can return a c4d.BitmapButtonStruct object for the second item in the tuple. See NodeData.GetDParameter() documentation.
Unfortunately this is useless as a node can't respond to MSG_DESCRIPTION_GETBITMAP currently.
gr4ph0s: The errors in c4d.BitmapButtonStruct docs will be fixed.

Hello!
Thank you, Adam!
Sadly only now i read your answer, Yannick, after trying half a day ;)
My attempt was:
def Message(self, node, type, data) :
if type==c4d.MSG_DESCRIPTION_GETBITMAP:
if data['id'][0].id==c4d.ID_BITMAP:
dir, file = os.path.split(__file__)
path = os.path.join(dir, "res", "test.tif")
bm = bitmaps.BaseBitmap()
bm.InitWith(path)
data['bmp'] = bm
return True
return False
def GetDParameter(self, node, id, flags) :
if id[0].id == c4d.ID_BITMAP:
#BitmapButtonStruct bbs = BitmapButtonStruct(static_cast<PluginObject*>(node), id, dirty);
#t_data = GeData(CUSTOMDATATYPE_BITMAPBUTTON, bbs);
bbs = c4d.BitmapButtonStruct(node, id, 0)
return (True, bbs, flags | c4d.DESCFLAGS_DESC_LOADED)
return False
def SetDParameter(self, node, id, t_data, flags) :
if id[0].id == c4d.ID_BITMAP:
flags = flags | c4d.DESCFLAGS_DESC_LOADED
return True
But data in Message was always None...
Nevertheless thank you for your help :)
Cheers,
Mark.
