Question about events

wxPython Users
1

Hi all,

Is it possible to know if a user has clicked or done "Enter" on a button ?
I tried :

    btn.Bind(wx.EVT_CHAR, self.EvtChar)

For "F6" key, I go to self.EvtChar, but for "Enter" key, not ...

Friendly.

Hi Ronnie, and all,

Thank you, four your answer, but this does not work !...

However, after more analysis, I have found that I don't take the good way to solve the problem.

The problem is exactly the next :

- On a panel, there is a wxTextCtrl and a wxButton.
- When the user enter a barcode (with a scanner) in the wxTextCtrl, the program do many things (1/2 to 1 sec.) and come back to the wxTextCtrl (wxCallAfter(SetFocus), naturaly, the cursor would go to the button).
- Meanwhile, the user read a new barcode
- Sometimes, almost under linux, because the user have read to much quickly a new barcode, the characters of the barcode are lost and the "enter" at the end is taken by the button

Now, I think the best solution would be to keep in a buffer the characters read and to restore them when the cursor come back in the wxTextCtrl after the wxCallAfter(SetFocus) will be done.

But, I don't know how to do this and I don't understand why the character are lost and why the system does not wait the wxCallAfter(SetFocus) was done before accepting characters ?

Hope somebody have a idea ...

Thanks in advance ...

Sound to me like it would be best to not take so long to do whatever you do before it is ready to take the next entry. Can you grab the data and either save the processing for later, or hand it off to a worker thread?
