+
+== Statically in RML ==
+The easiest way to attach to events with python is to write your code directly into the RML files, using the on* attributes. When the event is fired three global variables are set up, ''document'', ''event'' and ''self''.
+
+||self||The element thats currently being processed||
+||[wiki:documentation/PythonManual/Documents document]||The document the element thats currently being processed belongs to||
+||[wiki:documentation/PythonManual/Events event]||The event thats currently being processed||
+
+Example:
+{{{
+<button onclick="print('Clicked!')"/>
+}}}
+
+To aid in the coding of inline Python code, libRocket allows multiple lines of Python code can be put on one line, separated by a semicolon. The parser will then reformat this code before passing it to the Python interpreter.
+
+Example:
+{{{
+<button onclick="print('Line 1');print('Line 2')"/>
+}}}
+
+
+== Dynamically from Python Code ==
+
+The Python version of AddEventListener is modelled directly on Javascript. This allows you to bind any callable Python object (free function or method) or string to an event.
+
+Method 1:
+{{{
+element = document.GetElementById('button')
+element.AddEventListener('onclick', "print('Line 1');print('Line 2')", True)
+}}}
+
+Method 2:
+{{{
+def OnClick():
+  for i in range(10):
+    print('Line ' + str(i))
+
+element = document.GetElementById('button')
+element.AddEventListener('onclick', OnClick, True)
+}}}
