I'm not sure if this is what you mean but you can see all events before they are delivered to their widgets by overriding FilterEvent in the app object. You then use SetCallFilterEvent(True) to turn it on. Be sure to return -1 from your FilterEvent if you want to allow the event to continue to be processed normally.

thanks Robin,

I think that's exactly what I meant.

I want to record all events,
and then use these events later on in a test suite.

unfortunately, it doesn't seem to work:
the following code doesn't print anyting:

# app = wx.PySimpleApp ()
    app = wx.App ()

    app.FilterEvent_Old = app.FilterEvent
    def My_FilterEvent ( *args, **kwargs ) :
        print '&&&&&', args
        #app.FilterEvent_Old ( *args, **kwargs )
        return -1
    app.FilterEvent = My_FilterEvent
    app.SetCallFilterEvent ( True )

now searching on FilterEcent on Google,
I came across this message from you (august 2004):

When using the wxWidgets C++ api, you can override wxApp::FilterEvents
in order to intercept/log/etc all events. FilterEvents doesn't seem to
be exposed in the wx.App wrapper object.

Correct. I left it out because the overhead of checking for the
existence of a Python FilterEvents method on every event in the 99.9% of
apps that wouldn't use it seems excessive. I do however have a ToDo
list item to create a new wx.FilterableApp class that would let you do
it for the other 0.1% of apps, but I havn't gotten to it yet.

Is there any other way to
intercept all events as they come?

Not without explicitly binding all the events.

Maybe FilterEvent is still not implemented ?

It needs to be an actual overridden method, not a monkey-patched one. Try it like this:

import wx

class MyApp(wx.App):
     def FilterEvent(self, evt):
         print evt
         return -1

app = MyApp(redirect=False)
app.SetCallFilterEvent(True)
frm = wx.Frame(None, title='Hello')
frm.Show()
app.MainLoop()

     app.SetCallFilterEvent ( True )

hello Robin,

one additional question, which probably you can answer,
if I store all the (important) events in a log file,
and I want to playback the recorded events,
how shouls I inject these events ?

thanks,
Stef

There isn't a clean and easy way to do it in 2.8, at least not if you want the native widgets to see real native events as if they are coming from the system. Starting with 2.9.2 we'll have wx.UIActionSimulator. wxWidgets: wxUIActionSimulator Class Reference

thanks Robin,

for the moment I'll if there are other (simple) solutions (autoit?)
