I created a button through UserData with:
UD=c4d.GetCustomDataTypeDefault(c4d.DTYPE_BUTTON)
UD[c4d.DESC_NAME] = "Press Me"
UD[c4d.DESC_CUSTOMGUI] = c4d.CUSTOMGUI_BUTTON
node.AddUserData(UD)
(actually, I created more than one button)
Now, how can I check what button was pressed.
I believe it is inside the Message method but... how?!

I think it is:
NodeData.Message(self, node, type, data)
| MSG_DESCRIPTION_COMMAND | Sent by for example BUTTON (description element). See [example](file:///D:/Users/pgrooff/Documents/pim/c4d/Python%20Help%20R15/help/modules/c4d.plugins/BaseData/NodeData/index.html#msg-description-command-example) below. |

I had tried that but it returns me the same value, no matter what button I press 
I used this code to check it out:
def Message(self, node, type, data) :
if type==c4d.MSG_DESCRIPTION_COMMAND:
bt = data['id'][0].id
print bt

Here is how I do it in C++ (sorry).
I assume you already check this forum.
There are multiple posts about e.g. MSG_DESCRIPTION_COMMAND
Bool SolarObject::Message(GeListNode* node, Int32 id, void* data)
{
switch (id)
{
case MSG_DESCRIPTION_COMMAND: // MSG_DESCRIPTION_COMMAND is send when button is clicked
{
DescriptionCommand *dc = (DescriptionCommand* )data; //data contains the description ID of the button
Int32 button = dc->id[0].id; //Get the ID of the button
//GePrint ("MSG_DESCRIPTION_COMMAND: " + String::IntToString(button));
switch (button) //Check for different button IDs
{
case SETKEY: // set key
You can also try checking for MSG_DESCRIPTION_CHECKUPDATE
case MSG_DESCRIPTION_CHECKUPDATE: // MSG_DESCRIPTION_CHECKUPDATE is send UD field is clicked
{
//BaseContainer *data = ((BaseObject* )node)->GetDataInstance();
DescriptionCheckUpdate *dcu = (DescriptionCheckUpdate* ) data;
Int32 button = dcu->descid[0][0].id;

I don't understand why you can't get it's value just like any other UserData gizmo?
This script that will create a UD button to an object:
import c4d
def main() :
obj = doc.GetFirstObject()
if not obj: return False
bc = c4d.GetCustomDatatypeDefault(c4d.DTYPE_BOOL) #Create the default container
bc.SetString(c4d.DESC_NAME,"Click Me") #The text on the button
bc.SetLong(c4d.DESC_CUSTOMGUI,c4d.CUSTOMGUI_BUTTON) #Sets the bool gizmo to be a button
button = obj.AddUserData(bc) #Add the userdata to the object
obj[button] = False #Assign a default value to it when it created
c4d.SendCoreMessage(c4d.COREMSG_CINEMA, c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE))
c4d.EventAdd()
if __name__=='__main__':
main()
To get it's value this should be all you need to do.
#Since the button gimzo was the first UD item created
#It has a level ID #1
btnValue = obj[c4d.ID_USERDATA,1] #<---Returns true/false depending on the button's click state
print btnValue
Each new button should have it's own level#.
So you just use that number instead of #1 in the code for getting the value of the other buttons.
Are you doing something different than this Rui?

It worked great!! 
Thank you, Scott.
I just had to make sure that after reading the value I set the value back to False.
Now I just need to know how to change the name of the UserData tab into another thing.
And, how to simulate multi-column groups of UD parameters programmatically.
