Instance of wx.App

#1

What’s the best method of getting an instance of “theApp”
wx.App.Get(), wx.GetApp(), wx.App.GetInstance() all return typeof wx._core.AppConsole

I would like to get an instance that is typeof wxApp or wxAppBase

I see native has GetGUIInstance()

Are you calling these using python or C++ ?

When I run the code below they all return the same wx.App object.
I am using Python 3.10.12 + wxPython 4.2.1 gtk3 (phoenix) wxWidgets 3.2.2.1 on Linux Mint 21.2

import wx

app = wx.App()
print(app)
print(wx.GetApp())
print(wx.App.Get())
print(wx.App.GetInstance())
print(wx.AppConsole.GetInstance())

Output:

/usr/bin/python3.10 /home/richardt/Development/python/exp/hci/wxpython/app/app_exp_1.py 
<wx.core.App object at 0x7f677992bd90>
<wx.core.App object at 0x7f677992bd90>
<wx.core.App object at 0x7f677992bd90>
<wx.core.App object at 0x7f677992bd90>
<wx.core.App object at 0x7f677992bd90>

I just use wx.GetApp() in my own python code.

Hi Richard

Note, I am creating “wxApp’ in C++, but accessing it from Python

This is what I get

def PyRxCmd_doit():
    try:
        print(sys.version)
        print(wx.version())
        print(wx.GetOsDescription())
        
        print(wx.GetApp())
        print(wx.App.Get())
        print(wx.App.GetInstance())
        print(wx.AppConsole.GetInstance())
        
    except Exception as err:
        traceback.print_exception(err)

Output:

My hunch is wx.App() creates a wxPyApp and not a wxApp.
The solution for embedded might be to create their own wrapper
I was able to do this using wxPyConstructObject(pApp, wxT(“wxPyApp”));
