I am trying to get a dialog box working using wxpython under Centos 6.

Here is my initialzation code which give the error: object has no attribute ‘OnPressEnter’

I am new at this so be kind :slight_smile:

Ideas as to what I am doing wrong?

Thanx alot!

def initialize(self):
sizer = wx.GridBagSizer()

self.entry = wx.TextCtrl(self,-1,value=u"Enter File Name")
sizer.Add(self.entry,(0,0),(1,1),wx.EXPAND)
···

###########################

next lines cause error

AttributeError: object has no attribute ‘OnPressEnter’

self.Bind(wx.EVT_TEXT_ENTER,self.OnPressEnter,self.entry)

button = wx.Button(self,-1,label="Click me!")
sizer.Add(button, (0,1))

###########################

next line cause errors

self.Bind(wx.EVT_BUTTON, self.OnButtonClick, button)

self.label = wx.StaticText(self,-1,label=u'Hello !')
self.label.SetBackgroundColour(wx.BLACK)
self.label.SetForegroundColour(wx.RED)
sizer.Add(self.label,(1,0),(1,2),wx.EXPAND )
self.Refresh()

sizer.AddGrowableCol(0)
self.SetSizerAndFit(sizer)
self.SetSizeHints(-1,self.GetSize().y,-1,self.GetSize().y );
self.Show(True)

John,
you can bind to button methods you have to add them, usually as a member of the same class.

The error "Object has no attribute" points out that "OnPressEnter" does not exist for the object, have you defined this event handler? Have you written it exactly the same?

Hi Werner,

Might have been a typo - I moved the code higher in the class code and then the error stopped.

The error stops but when I press enter, it does not execute my code.

Here is test code I am using:

#!/usr/bin/python

-- coding: iso-8859-1 --

try:
import wx
except ImportError:
raise ImportError,“The wxPython module is required to run this program”

class simpleapp_wx(wx.Frame):
def init(self,parent,id,title):
wx.Frame.init(self,parent,id,title)
self.parent = parent
self.initialize()

def initialize(self):
    sizer = wx.GridBagSizer()

    self.entry = wx.TextCtrl(self,-1,value=u"Enter text here.")
    sizer.Add(self.entry,(0,0),(1,1),wx.EXPAND)
    self.Bind(wx.EVT_TEXT_ENTER, self.OnPressEnter, self.entry)

    button = wx.Button(self,-1,label="Click me !")
    sizer.Add(button, (0,1))
    self.Bind(wx.EVT_BUTTON, self.OnButtonClick, button)

    self.label = wx.StaticText(self,-1,label=u'Hello !')
    self.label.SetBackgroundColour(wx.BLUE)
    self.label.SetForegroundColour(wx.WHITE)
    sizer.Add( self.label, (1,0),(1,2), wx.EXPAND )

    sizer.AddGrowableCol(0)
    self.SetSizerAndFit(sizer)
    self.SetSizeHints(-1,self.GetSize().y,-1,self.GetSize().y );
    self.Show(True)

def OnButtonClick(self,event):
    print "You clicked the button !"

def OnPressEnter(self,event):
    print "You pressed enter !"

if name == “main”:
app = wx.App()
frame = simpleapp_wx(None,-1,‘my application’)
app.MainLoop()

The button click works but when I press Enter nothing happens.

Thoughts??

Thanks,

John

Hello John, you need to set the style TE_PROCESS_ENTER for the TextCtrl to recieve events for the Enter-Key.

self.entry = wx.TextCtrl(self,-1,value=u"Enter text here.",style=wx.TE_PROCESS_ENTER)
