OnExit Event for an TexCtrl?

wxPython Users
1

Hi,

I am searching for an easy way to trigger an event, when finishing writing something into a TextCtrl. I know ‘OnExit’ can do that in Delphi, but this is not Delphi. EVT_KILL_FOCUS seems not to work with TextCtrls and is the only thing so far i found.

An alternative would be to let EVT_TEXT only react to user actions (changing something) and not to program actions. But how?

Suggestions?

Hello Michael,

I don't know on which platform are you on, but for me EVT_KILL_FOCUS works as it should (Windows 2000/XP, wxPython 2.6.2.1). If you want to detect when the user changes the focus from a TextCtrl to something else, it should work. Other way may be to detect an EVT_TEXT_ENTER (the user presses the enter key) and do something when this event fires.

Hi Andrea, hi Josiah,

it works now, although I do not really understand why.

I have had bound the events like normal buttons:

self.Bind(wx.EVT_MYEVENT,MyFuction,MyObject)

But that does not work for the KILL_FOCUS event (it does for the TEXT event …).

self.MyObject.Bind(wx.EVT_EVENT,MyFunction)

This works (thanks Josiah). But why? Where is the difference?

Thanks so far,
Michael

From a post later in the thread I linked to before:
http://lists.wxwidgets.org/cgi-bin/ezmlm-cgi?11:mss:47722:miebbcjeoepdcgoocmbd

Apparently button events are command events, as seemingly are
wx.EVT_TEXT, but not wx.EVT_KILL_FOCUS, nor wx.EVT_TEXT_ENTER.

I would wager that binding to the object itself always works.
