SWIG/Python detected wxPasswordEntryDialog Memory Leak

Question

I'm using a wx.PasswordEntryDialog to get a password from the user, but every time I create a PasswordEntryDialog I get this error:

swig/python detected a memory leak of type 'wxPasswordEntryDialog *', no destructor found.

Here is one of the places that causes it:

def getpass():
    dialog = wx.PasswordEntryDialog(None, 'Enter your password')
    if dialog.ShowModal() == wx.ID_OK:
        value = dialog.GetValue()
    else:
        value = None
    del dialog
    return value

Answer 1

I found that you can get rid of the message by replacing the line

del dialog

with

dialog.Destroy()

(I'm using wxWidgets/wxPython 2.9.3, if that's relevant.)
