[wxPython] Window id will not set

[dodle]

When I create an instance of a wx.Frame, I set the id to -1, but when I try to retrieve that id, it comes back as -201.


class App(wx.App):
def OnInit(self):
frame = wx.Frame(None, -1, "Blah") # Set id to "-1"
print frame.GetId() # Id prints as "-201"
frame.Show()
self.SetTopWindow(frame)
return True

app = App(0)
app.MainLoop()Can someone tell me why this is happening? If I want to set the frame's id, I have to do:
frame.SetId(-1)Then it prints correctly. But shouldn't that id be set at construction?

-1 is the value of wx.ID_ANY, the "generate a unique ID for me" constant.

Ok, thanks. I didn't realize that. But now I have a different issue: I've created a wx.Frame with a method to print an event object's id. But once again, after calling the method, the id prints out as -201.
import wx


class MainWindow(wx.Frame):
def __init__(self, parent, id=wx.ID_ANY, title=""):
wx.Frame.__init__(self, parent)

print id # Id prints out correctly here "100"

# Call event handler with wx.Frame as event object
wx.EVT_WINDOW_CREATE(self, self.PrintId)


def PrintId(self, event):
# Print the Id
print event.GetEventObject().GetId() # Id prints out as -201
event.Skip()

class App(wx.App):
def OnInit(self):
frame = MainWindow(None, 100, "Blah")
frame.Show()
self.SetTopWindow(frame)
return True

app = App(0)
app.MainLoop()But I can't see why it wouldn't print out 100. Doesn't this call the method with the wx.Frame as the event object
wx.EVT_WINDOW_CREATE(self, self.PrintId)

wx.EVT_WINDOW_CREATE(self, self.PrintId)

It does, but you aren't passing the id from MainWindow.__init__ to wx.Frame.__init__.

Ok, I see. Thanks, Robots.

wx.Frame.__init__(self, parent, id)
