Picture in UserData

Ok thanks.
I can't figure out how to apply the image to the button. In my C++ code I use SetImage() but it's not working in my UserData.

import c4d,os  
def main() :  
  
  fn = c4d.storage.GeGetC4DPath(c4d.C4D_PATH_DESKTOP)  #Gets the desktop path  
  path = os.path.join(fn,'myimage.jpg')                #The path to the image    
        
  bc = c4d.GetCustomDatatypeDefault(c4d.CUSTOMDATATYPE_BITMAPBUTTON)  
  bc[c4d.DESC_NAME] = 'my image'  
  bc.SetFilename(12345, path)  
  bc.SetImage(path, False)    #<---Error...How do we add the image?  
        
  entry = op.AddUserData(bc)  
  
  c4d.SendCoreMessage(c4d.COREMSG_CINEMA, c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE))  
  c4d.EventAdd()  
        
if __name__=='__main__':  
  main()

First, the image needs to be loaded, of course. I use:

pic=bitmaps.BaseBitmap()
pic.InitWith(image_path)

Then, the image needs to be registered with an unique ID (get it from plugincafe) :

c4d.gui.UnregisterIcon(UNIQUE_ID)

Now, place it in the UserData (or in the description) with something like this:

mypic=c4d.GetCustomDataTypeDefault(c4d.DTYPE_BOOL)
mypic[c4d.DESC_NAME] = "Preview"
mypic[c4d.DESC_CUSTOMGUI] = c4d.CUSTOMGUI_BITMAPBUTTON
mypic[c4d.BITMAPBUTTON_ICONID1]=UNIQUE_ID
mypic[c4d.BITMAPBUTTON_ICONID2]=UNIQUE_ID
mypic[c4d.DESC_PARENTGROUP] = node.GetUserDataContainer()[0][0]
preview=node.AddUserData(pic)
node[preview]=1

Thanks Rui.
I didn't know we had to use registered IDs for images too.

Here's a script example in case anyone needs it:

import c4d, os  
from c4d import gui, bitmaps  
def main() :  
  
  #WARNING: Register your image with a unique ID from the plugincafe.com instead of 12345!!  
  imageID = 12345  
  
  fn = c4d.storage.GeGetC4DPath(c4d.C4D_PATH_DESKTOP)  #Gets the desktop path  
  path = os.path.join(fn,'myimage.jpg')                #The path to the image  
  image = bitmaps.BaseBitmap()  
  image.InitWith(path)  
  gui.RegisterIcon(imageID, image)  
  
  obj = doc.GetActiveObject()   
  if not obj: return False     
  
  container = c4d.GetCustomDataTypeDefault(c4d.DTYPE_BOOL)  
  container.SetString(c4d.DESC_NAME, "My Image")  
  container.SetLong(c4d.DESC_CUSTOMGUI, c4d.CUSTOMGUI_BITMAPBUTTON)  
  container.SetString(c4d.BITMAPBUTTON_TOOLTIP, "Click ME!")  
  #container.SetLong(c4d.BITMAPBUTTON_BORDER, c4d.BORDER_OUT) #Creates a raised button border if that's desired  
  container.SetLong(c4d.BITMAPBUTTON_BUTTON, True)      #Creates indented border when the button is clicked  
  container.SetLong(c4d.BITMAPBUTTON_ICONID1, 12345)    #Off state: Puts your custom image on the button  
  container.SetLong(c4d.BITMAPBUTTON_ICONID2, 5159)     #On State:  Puts a cube icon image on the button  
  
  obj.AddUserData(container)                            #Adds the userData to the object  
  
  c4d.EventAdd()  
  
if __name__=='__main__':  
  main()

Using just c4d.EventAdd() to refresh the document is not enough.
We need to force an AM refresh with:

c4d.SendCoreMessage(c4d.COREMSG_CINEMA, c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE))
c4d.EventAdd()

Does it not work for you without it?
It works fine for me without that code.

The only time I've needed to use that code is when I'm deleting, or changing existing UserData items.
Mostly when I delete one UD item and leave other ones behind in the manager.
I've never needed to use that code when creating new UD items.

Well, in my plugin I have to delete them all. So, I really need to force a refresh of the AM.

Hi ScottA

Is there maybe a way to resize the image button of that code of yours???

For which one?

CUSTOMGUI_BITMAPBUTTON - Changes it's size automatically depending on the size of the image used.
CUSTOMGUI_BITMAPBOOL - Displays an icon size of your image. Something like 32x32.

I don't see any way to manually set the sizes for either of them.
But I could be wrong.

Hi ScottA

I see this piece of code manually set the size off the button:

container.SetLong(c4d.BITMAPBUTTON_FORCE_SIZE, 64)

Good find. Thanks for posting it.
The SDK lists that as private. So I never tried it.
