Re: [Discuss-gnuradio] a question about wx.App()

Thank u! Your explanation to me is rather explicit! I have found out the App() and downloaded wxWidgets 2.8.7, from which i checked out the app.cpp file, thank u! But I still have sth confusing me.

1, e.g. there is a method called detachmenubar in the /src/gtk/frame.cpp, but i cannot find that method in http://docs.wxwidgets.org/stable/wx_wxframe.html#wxframeoncreatetoolbar, a class method list for wxframe and vice versa (there is a method called oncreattoolbar in that list, but it is not in the frame.cpp file). I dont know why!!

2, we also used the class wx.boxsizer, but there is no file called boxsizer under wxWidgets 2.8.7. We cannot find that in wxWidgets, why is that??

3, now i can see the cpp file of app(), cause i downloaded wxWidgets 2.8.7, but i cannot find its source file under my system (Ubuntu 7.10 Gusty, ). The only one i could find in my laptop is wxPython (there should be wxWidgets or sth like that since usrp_wfm_rcv.py file is running successfully).

4, there is also a problem causing my headache: OnInit is a method of class stdapp(wx.app), i think it should be run somehow, but i cannot see how it is run! there is no object calling this method!

I spent 48 hours digging for the answers of these kinda problems, but still could not find the answers, maybe i am too stupid...... i am very depressed right now. Hopefully you could help me figure them out. Thank you very much!!!

I'm glad you caught my error .... "_core" instead of "_code" ;)

_core.py and _core_.so shuld be in the same directory (in your case, /
usr/lib/python2.5/sitepackages/wx-2.8-gtk2-unicode/wx ).  The 'so' is 
a shared library, created by wxPython, and is part of a SWIG interface 
into wxWidgets (which is a C++ compiled library and includes).

In order to access those codes, you'll need the original source 
tarball, extract it, and find those files.  Depending on your OS-type, 
this can be done as part of the code install - or you might need to 
download the tarball (e.g., from < http://www.wxwidgets.org/downloads/ 
>), extract it, and then start searching around in it.

For example, if you're running on MacOS X and using MacPorts, you can 
find the original source via:

sudo port -f patch wxWidgets
pushd `port dir wxWidgets`/work/wxWidgets*

and then search around from there (e.g. "grep -inr 'wx\.App' ..").  I 
would guess on most Linux'es, you're better off just downloading the 
original source tarball and working with it .... just makes sure you 
find the correct version of wxWidgets ;)  - MLD
