I am trying to show bubble help for some controls in GUI shown by NodeData (all GUI controls are loaded from description file).
I found some example using GeDialog and its Message method (https://developers.maxon.net/forum/topic/7408/9180_how-to-implement-tooltips-like-bitmapbutton#36397) :

virtual Bool Message(const BaseContainer& msg, BaseContainer& result) {
    switch (msg.GetId()) {
        case BFM_GETCURSORINFO: {
            result.SetId(BFM_GETCURSORINFO);
            result.SetLong(RESULT_CURSOR, MOUSE_BUSY);
            result.SetBool(RESULT_SUPPRESSBUBBLE, FALSE);
            result.SetString(RESULT_BUBBLEHELP_TITLE, "Bubble Help Title");
            result.SetString(RESULT_BUBBLEHELP, "Cool description stuff here.");
            result.SetString(RESULT_HELP1, "RESULT_HELP1");
            result.SetString(RESULT_HELP2, "RESULT_HELP2");
            result.SetString(RESULT_HELP3, "RESULT_HELP3");
            result.SetString(RESULT_HELP4, "RESULT_HELP4");
            break;
    }
}
        return super::Message(msg, result);
    }

Obviously, I cannot use this method directly as NodeData has no message handler for GUI messages. Also, I would stil need to determine, which control is located at position given by BFM_DRAG_SCREENX/BFM_DRAG_SCREENY.

Is there anything I could use instead?
