wxPython programs do not get activated after launching

wxPython Dev

When I launch a wxPython program on macOS (Apple M2), it stays in background, and come to foreground (and get wx.EVT_ACTIVATE event) only when I manually click on its icon on the Dock.

There is no such issue with the GUI programs written with Tkinter or PyQt.

I tried googling for solutions, and only got a trick of manually bring the program to foreground by calling NSApp().activateIgnoringOtherApps_(True) through the AppKit module – but this should be a temporary workaround.

Here is the test code:

import wx

def on_act(evt):
    print('EVT_ACTIVATE')

app = wx.App()

frame = wx.Frame(None, title='Hello World!')
frame.Bind(wx.EVT_ACTIVATE, on_act)
frame.Show()

app.MainLoop()

My environment is:

  • CPU: Apple M2 Pro
  • OS: macOS 13.4.1
  • Python 3.11.4 (installed through brew install python)
  • wxPython 4.2.1
MacOS window opens in the background and does not receive focus

Hi @Alan, I have the same problem too, have you found a not temporary solution?
