I'm attempting to run the simple Kivy application located here on OSX.
At first, CEF failed during initialization. The output was:

Trace/BPT trap: 5
I found a discussion here that suggested manually setting the local_pak
flag to avoid this error. I made the following changes to the example code starting on line 150:
# Command line switches set programmatically
g_switches = {
"locale_pak": cefpython.GetModuleDirectory()
+"/Resources/en.lproj/locale.pak",
}
#init CEF
cefpython.Initialize(settings, g_switches)
This solved my initialization issue! The CEF Browser appears, but will not respond to any input from my keyboard. I am also unable to scroll using my trackpad, although I am able to use it to click links.
I gave the whole background on this issue in case I took the wrong route by changing the locale_pak
flag.
I'm using:
Kivy v1.9.0
Python v2.7.6
cefpython3 v31.2
I should also mention that I am able to run the wxpython.py
example that is packaged with cefpython3
without issue.
Any help would be greatly appreciated!
The issue is that in the kivy_.py example key codes were translated specifically for Linux only, see the translate_to_cef_keycode() function:
Support for Windows/OSX key codes needs yet to be added.
