Send message to tooldata
-
How can I send data from a command plugin dialog to a tooldata plugin?
I tried following in the command pluginself.mode = id #c4d.SpecialEventAdd(PLUGIN_ID2, p1=id, p2=id) msg = c4d.BaseContainer() msg[1] = id self.CoreMessage(c4d.EVMSG_TOOLCHANGED, msg)
But nothing is received in the tooldata plugin.
def Message(self, node, type, data): if type==c4d.EVMSG_TOOLCHANGED: print "EVMSG_TOOLCHANGED" if data['id'][0].id==PLUGIN_ID2: print "Pushed button with the ID", PLUGIN_ID2 return True def CoreMessage(self, id, msg): if id == PLUGIN_ID2: print "Message received." ....

If I remember correctly we did discuss the other way (from CommandData to ToolData) quite a while ago (see https://developers.maxon.net/forum/topic/10044/13513_using-objectmessage). But I guess using this same technique could still be applicable to your current request.
Most important is to understand that a CoreMessage is not captured by a ToolData. This type of message can only be captured by a MessageData plugin, where you then could "translate" it into a message that actually is sent to the ToolData.
What I have been successful in using is, performing following from the "transmitter":
BasePlugin* tool = FindPlugin(TOOL_PLUGIN_ID, PLUGINTYPE::TOOL); if (tool) tool->Message(TOOL_MSG_PREPAREDATA);
Where TOOL_PLUGIN_ID is the plugin ID of the ToolData, and TOOL_MSG_PREPAREDATA is a custom defined message, using a unique plugin ID.
And then using following in the "receiver" ToolData:
Bool MyToolData::Message(BaseDocument *doc, BaseContainer &data, Int32 type, void *t_data) { if (type == TOOL_MSG_PREPAREDATA) { PrepareData(); } return DescriptionToolData::Message(doc, data, type, t_data); }

Furthermore, I am not sure you can simply sent out a EVMSG_TOOLCHANGED.
Why would you do so?
Best is to actually perform a change of tool (by doing adoc->SetAction(...)
), which will automatically sent out this message. But of course the message being a CoreMessage it can only be captured by a MessageData plugin. Again, you could provide this detection and "translate" that captured EVMSG_TOOLCHANGED into a "tool->Message(custom_msg_id_toolchanged)", which you would then listen to in your ToolData::Message() -
