[wxPython] Re: event "wxTextCtrl loses focus"?

I think your question has been answered, but I would like to address another
point:

If I was a user of your software, by indicating that I made a mistake only
after I switch away, I have to switch back to correct the error. This could
get annoying very quickly, especially if I don't know how to fix the error
and I try something, switch away, no, go back, change it, switch away, still
didn't get it, etc... (Trust me, there are users out there that do this)

I don't know why you want the following to hold:

I do not want to do this validation while
the user is still typing.

...but one thing to try is to trigger validation AFTER the user has stopped
typing, but BEFORE he/she switches away. This can be done with a timer,
that's activated when a key is hit, then de-activated/re-activated (or
reset) when another key is hit, until the user stops long enough for the
timer to trigger the validation function (about half a second to a second),
which turns off the timer (until another key is hit), validates the contents
of the field and then points out the error in a nice way to the user, like a
squiggly line under the text or a message in the status bar, etc..

Just-my-2-cents-on-usability-ly y'rs...

Subject: [wxPython] event "wxTextCtrl loses focus"?
Reply-To: wxpython-users@wxwindows.org

I would like to present a data input form
using wxPython. E.g., using wxTextCtrl:

    parameter 1 _____________
    parameter 2 _____________

The underlines represent the input fields.

I would like to do some validation for
each parameter when the user hits Enter
or switches between the input fields.
I do not want to do this validation while
the user is still typing.

I figured out how to use
EVT_TEXT_ENTER(self, ID, self.EvtText)
to trigger the validation when the users
hits enter. Unfortunately, my experiments
with EVT_KILL_FOCUS have not been
successful. How can I register an
event handler that gets called when a
wxTextCtrl input field loses focus?

Are there wxPython applications with
data input forms that I could use for
learning?

Thanks for any help!
