pybee / toga-demo Goto Github PK

I installed the following depedencies:

dnf install python3-gobject pywebkitgtk

But I can’t get the demo running:

(toga) $ toga-demo

Seems like width is not what it is supposed to be, I'll take a look later, this is just so it does not get lost :D

Thanks for the Gtk support! Unfortunately, the demo is failing to find the WebKit bindings on Fedora, and the number of different projects and version numbers interacting, as well as the major naming differences between Debian and Fedora in this area, makes it hard to figure out what it's actually looking for:

ValueError: Namespace WebKit2 not available for version 3.0

gir1.2-webkit2-3.0 seems to be the relevant Debian package (which is mentioned on toga's Gtk support page), and looking at https://packages.debian.org/sid/gir1.2-webkit2-4.0 shows that's the Gobject introspection bindings for WebKit2 3.0

However, I can't find anything similar for Fedora, which suggests this may work quite differently on non-Debian derived Linux systems.

Installed toga-demo on Ubuntu 12.04.1 in a brand new virtualenv; pip used the source tar.gz package.
Upon launching "toga-demo" from the CLI it crashes due to missing icons. After checking it looks like the icons are indeed missing from the source package on Pypi. This did not happen on OSX 10.8 where the wheel package gets used by pip and everything installs and runs fine.

Followed the tutorial on RTD, but I get this error running toga-demo:
AttributeError: module 'toga' has no attribute 'App'
Needless to say that if I try the first example it returns the same error.

I tried running the toga-demo 0.2.14 with python3.6.2 under OS X 10.12.6 and got this traceback

The demo runs and buttons and menus work after changing line 55 in toga_demo/app.py from
self.main_window.toolbar = [cmd1, toga.SEPARATOR, cmd2]
to
self.main_window.toolbar.add(cmd1, cmd2)

but it displays this traceback in the Terminal

This traceback is also displayed for the scripts in the toga tutorial.

Thanks for creating toga and the whole BeeWare project.

executing toga-demo in command prompt gives the following error:
