Dear All,

I want to "bind" a customized message handler to handle the keyboard message
(left/right arrow button down) sent from a wx.TextCtrl. Seems following code
does not work.I dont know why. Any one can tell me how to do that? Thanks in
advance.

# --------------------------------------------------------------
class MyFrame(wx.Frame)
    def __init__(self)
        ....
        txt = wx.TextCtrl( self, ....)
        self.Bind( wx.EVT_KEY_DOWN, self.OnKeyDown, txt)

    def OnKeyDown(self, event )
        ...

Best Regards
Michael

Hi Micheal,

The following should work:

class MyFrame(wx.Frame):
def init(self):
…
textctrl = wx.TextCtrl(self, -1)
textctrl.Bind(wx.EVT_CHAR, self.OnChar)

    ...
def OnChar(self, event):
    if event.GetKeyCode() == wx.WXK_DOWN:
        print 'its a key down'
    else:
        # Event skipped so goes to textctrl as normal
        event.Skip()
