possible issue with unhandled win32 exception using Python 3.12.1

[AndrewJHetzel]

Operating System: Windows 10, version 22H2, build 19045.3803 wxPython version: 4.2.1 (Phoenix) wxPython source: pypi Python version: 3.12.1 Python source: stock from python.org

I tried running "Hello World, Part 2" (taken verbatim from https://wxpython.org/pages/overview/#hello-world) through VS Code. However, when I closed the GUI, I got the message that Python had stopped working due to an unhandled win32 exception in python.exe.

Code Example (click to expand)

```python #!/usr/bin/env python """ Hello World, but with more meat. """ import wx class HelloFrame(wx.Frame): """ A Frame that says Hello World """ def __init__(self, *args, **kw): # ensure the parent's __init__ is called super(HelloFrame, self).__init__(*args, **kw) # create a panel in the frame pnl = wx.Panel(self) # put some text with a larger bold font on it st = wx.StaticText(pnl, label="Hello World!") font = st.GetFont() font.PointSize += 10 font = font.Bold() st.SetFont(font) # and create a sizer to manage the layout of child widgets sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(st, wx.SizerFlags().Border(wx.TOP|wx.LEFT, 25)) pnl.SetSizer(sizer) # create a menu bar self.makeMenuBar() # and a status bar self.CreateStatusBar() self.SetStatusText("Welcome to wxPython!") def makeMenuBar(self): """ A menu bar is composed of menus, which are composed of menu items.

On the # platforms that support it those letters are underlined and can be # triggered from the keyboard. menuBar = wx.MenuBar() menuBar.Append(fileMenu, "&File") menuBar.Append(helpMenu, "&Help") # Give the menu bar to the frame self.SetMenuBar(menuBar) # Finally, associate a handler function with the EVT_MENU event for # each of the menu items.

I suspect this may have been a sip issue that's since been resolved, can you try the latest snapshot builds? https://wxpython.org/Phoenix/snapshot-builds/

Woo Hoo! "wxPython-4.2.2a1.dev5626+a1184286-cp312-cp312-win_amd64.whl" did the trick for me! Thank you so much.
