Please help - EVT_CHAR

wxPython Users
1

I'm still having problems getting my application to acknowledge keyboard events. I've tried this on two machines, both linux boxes (apparently using wxGTK). Here's my latest attempt...

---start code---
#!/usr/bin/env python

from wxPython.wx import *
class Form1(wxPanel):
    def __init__(self, parent, id):
        wxPanel.__init__(self, parent, id)
        self.My_Text = wxTextCtrl(self, wxNewId(), '', wxPoint(20, 20))

        EVT_CHAR(self, self.kybdEvent)

    def kybdEvent(self, event):
        self.My_Text.WriteText(event.KeyCode())

app = wxPySimpleApp()
frame = wxFrame(None, -1, 'Some Frame')
Form1(frame,-1)
frame.Show(1)
app.MainLoop()
---end code---

What am I doing wrong? Any help would be GREATLY appreciated... TIA

import wx

class Form1(wx.Panel):
    def __init__(self, parent, id):
        wx.Panel.__init__(self, parent, id)
        self.My_Text = wx.TextCtrl(self, -1, '', (20, 20))

        self.Bind(wx.EVT_CHAR, self.kybdEvent)

    def kybdEvent(self, event):
        c = chr(event.KeyCode())
        self.My_Text.WriteText(c)

app = wx.PySimpleApp()
frame = wx.Frame(None, -1, 'Some Frame')
Form1(frame, -1)
frame.Show(1)
app.MainLoop()

change the EVT_CHAR linr to the following:
EVT_CHAR(self, self.My_Text.GetId(), self.kybdEvent)

you need to tell EVT_CHAR the ID of the control for which
to capture events.

Only the widget with the keyboard focus will generate CHAR or KEY events, and since they are not command events they are delivered only to the window they happen to, not their parents. Try binding the EVT_CHAR event to the text ctrl by using it for the first parameter of EVT_CHAR().
