[wxPython-users] Can FindReplace dialog have accelerator key?

[jeremy alexander]

Hi Josiah,

Thanks for the tip about PyPE but I don't think it
applies to what I am trying.  
I'm using the standard wxFindReplaceDialog widget
(pyPE doesn't seem to use the FindReplace dialog box).
 

The find loop in my application is using wxYield to
allow window updates.  The dialog has a cancel button
which when pressed kills the dialog.  I am trying to
also implement an abort feature in which the find is
stopped but the dialog remains.  The plan was to use
an accelerator key (like 'Escape') which would result
in an abort flag being set; the find loop would then
monitor the flag.  

Jeremy.
