wxPython Error

Jun 30th, 2009

When I run this code:

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
import wx
 
ID_FILE_QUIT = 101
 
class MainFrame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, wx.ID_ANY, title=title)
        self.menuBar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.fileMenu.Append(1, '&Quit\tCtrl+Q')
        self.Bind(wx.EVT_MENU, self.Close(), id=ID_FILE_QUIT)
        self.menuBar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menuBar)
        self.Show()
 
app = wx.App()
frame = MainFrame('Ya Mum')
app.MainLoop()
import wx

ID_FILE_QUIT = 101

class MainFrame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, wx.ID_ANY, title=title)
        self.menuBar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.fileMenu.Append(1, '&Quit\tCtrl+Q')
        self.Bind(wx.EVT_MENU, self.Close(), id=ID_FILE_QUIT)
        self.menuBar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menuBar)
        self.Show()

app = wx.App()
frame = MainFrame('Ya Mum')
app.MainLoop()

I get some error about expecting a callable object for self.Bind()?

Can someone tell me why this is happening?

Theres ya problem!
You dont need to put the brackets after self.Close, the brackets are only used if you actually want to call the function, so take out those brackets and try again. That hopefully should fix your dilemma.

Make it idiot-proof, and someone will just make a better idiot

If paulthom12345's suggestion does not fix your problem, try to bind this way:

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
import wx
 
ID_FILE_QUIT = 101
 
class MainFrame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, wx.ID_ANY, title=title)
        self.menuBar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.fileMenu.Append(ID_FILE_QUIT, '&Quit\tCtrl+Q')
        self.Bind(wx.EVT_MENU, self.quit, id=ID_FILE_QUIT)
        self.menuBar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menuBar)
        self.Show()
 
    def quit(self, event):
        self.Close(True)
 
 
app = wx.App()
frame = MainFrame('Ya Mum')
app.MainLoop()
import wx

ID_FILE_QUIT = 101

class MainFrame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, wx.ID_ANY, title=title)
        self.menuBar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.fileMenu.Append(ID_FILE_QUIT, '&Quit\tCtrl+Q')
        self.Bind(wx.EVT_MENU, self.quit, id=ID_FILE_QUIT)
        self.menuBar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menuBar)
        self.Show()
        
    def quit(self, event):
        self.Close(True)


app = wx.App()
frame = MainFrame('Ya Mum')
app.MainLoop()

Forgot to mention this, but I also corrected line 10 to:

self.fileMenu.Append(ID_FILE_QUIT, '&Quit\tCtrl+Q')

Thanks guys, it turns out that I had to only put the function name, not call the function.

Better test it, that won't work!

Why not? It worked for me when I tested his code... and there's nothing wrong with his binding as I added another menu item with a separate function and ID and that still worked without conflict.

here is what I got:

File "c:\Users\Elijah Ministries\Desktop\daniweb.py", line 17, in <module>
frame = MainFrame('Ya Mum')
File "c:\Users\Elijah Ministries\Desktop\daniweb.py", line 11, in __init__
self.Bind(wx.EVT_MENU, self.Close(), id=ID_FILE_QUIT)
File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\_core.py", line 3911, in Bind
event.Bind(self, id, id2, handler)
File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\_core.py", line 3985, in Bind
target.Connect(id1, id2, et, function)

I wonder how it runs on you!
What version of wxPython do you have?

If you were to take the most updated code, you'd see that it works. This is what Lardmeister posted:

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
import wx
 
ID_FILE_QUIT = 101
 
class MainFrame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, wx.ID_ANY, title=title)
        self.menuBar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.fileMenu.Append(ID_FILE_QUIT, '&Quit\tCtrl+Q')
        self.Bind(wx.EVT_MENU, self.quit, id=ID_FILE_QUIT)
        self.menuBar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menuBar)
        self.Show()
 
    def quit(self, event):
        self.Close(True)
 
 
app = wx.App()
frame = MainFrame('Ya Mum')
app.MainLoop()
import wx

ID_FILE_QUIT = 101

class MainFrame(wx.Frame):
    def __init__(self, title):
        wx.Frame.__init__(self, None, wx.ID_ANY, title=title)
        self.menuBar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.fileMenu.Append(ID_FILE_QUIT, '&Quit\tCtrl+Q')
        self.Bind(wx.EVT_MENU, self.quit, id=ID_FILE_QUIT)
        self.menuBar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menuBar)
        self.Show()
        
    def quit(self, event):
        self.Close(True)


app = wx.App()
frame = MainFrame('Ya Mum')
app.MainLoop()

Which tom tetlaw acknowledged as he said "all I need to do is put the function name, not call the function". This is what we're doing by binding the function self.quit, rather than self.quit().
