Danny.OOo.Listeners.ListenerProcAdapters.py

This module has various helpers that make it extremely easy to create listeners on the fly, and make them call an arbitrary python procedure. <source lang=python>

3. Danny.OOo.Listeners.ListenerProcAdapters.py
5. A module to easily work with OpenOffice.org.

1. OOo's libraries

import uno import unohelper

1. --------------------------------------------------
2. An ActionListener adapter.
3. This object implements com.sun.star.awt.XActionListener.
4. When actionPerformed is called, this will call an arbitrary
5. python procedure, passing it...
6. 1. the oActionEvent
7. 2. any other parameters you specified to this object's constructor (as a tuple).

from com.sun.star.awt import XActionListener class ActionListenerProcAdapter( unohelper.Base, XActionListener ):

   def __init__( self, oProcToCall, tParams=() ): 
       self.oProcToCall = oProcToCall # a python procedure 
       self.tParams = tParams # a tuple 

   # oActionEvent is a com.sun.star.awt.ActionEvent struct. 
   def actionPerformed( self, oActionEvent ): 
       if callable( self.oProcToCall ): 
           apply( self.oProcToCall, (oActionEvent,) + self.tParams ) 

1. --------------------------------------------------
2. An ItemListener adapter.
3. This object implements com.sun.star.awt.XItemListener.
4. When itemStateChanged is called, this will call an arbitrary
5. python procedure, passing it...
6. 1. the oItemEvent
7. 2. any other parameters you specified to this object's constructor (as a tuple).

from com.sun.star.awt import XItemListener class ItemListenerProcAdapter( unohelper.Base, XItemListener ):

   def __init__( self, oProcToCall, tParams=() ): 
       self.oProcToCall = oProcToCall # a python procedure 
       self.tParams = tParams # a tuple 

   # oItemEvent is a com.sun.star.awt.ItemEvent struct. 
   def itemStateChanged( self, oItemEvent ): 
       if callable( self.oProcToCall ): 
           apply( self.oProcToCall, (oItemEvent,) + self.tParams ) 

1. --------------------------------------------------
2. An TextListener adapter.
3. This object implements com.sun.star.awt.XTextistener.
4. When textChanged is called, this will call an arbitrary
5. python procedure, passing it...
6. 1. the oTextEvent
7. 2. any other parameters you specified to this object's constructor (as a tuple).

from com.sun.star.awt import XTextListener class TextListenerProcAdapter( unohelper.Base, XTextListener ):

   def __init__( self, oProcToCall, tParams=() ): 
       self.oProcToCall = oProcToCall # a python procedure 
       self.tParams = tParams # a tuple 

   # oTextEvent is a com.sun.star.awt.TextEvent struct. 
   def textChanged( self, oTextEvent ): 
       if callable( self.oProcToCall ): 
           apply( self.oProcToCall, (oTextEvent,) + self.tParams )
