Do you use the Fedora packages for wxWidgets? If so, I can update them to include the patch. If not, you'll probably have to patch the source yourself as I don't expect Robin will make any more wxPython Classic releases.

Thank you folks for testing it out!
It would be a tremendous help, if this fix can find its way into a
form, that I can automatically bring it over with Fedora and wxPython.
I don't have the knowledge to build the code myself.
When I check
dnf install wxWidgets
my Fedora 24 reports:
Package wxGTK3-3.0.2-19.fc24.i686 is already installed, skipping.
For wxPython I get:
Package wxPython-3.0.2.0-10.fc24.i686 is already installed, skipping.

Yes, I plan to do so. There's currently already a wxGTK3 package update in testing and it's tied to a wxGTK (2.8.x) update, so I'd rather let that go through first and then do another update. So, it might take a week or so.

Thank you for porting the bug fixes.
I'd rather avoid doing this myself, if I can,
therefore I'll wait until you prepare the Fedora package, and then use
dnf to bring it over.

Great. There is an update in progress (there was one previously but it got obsoleted so the time delay got reset), so the official packages should be out soon.

I'm not sure whether my Fedora 24 pyInstaller-compiled wxPython
program will run and work identically on Ubuntu 16.04 LTS.
So I thought of preparing for the need to compile my program on Ubuntu too.
But from further research, I think both distros use glibc 2.23, so
perhaps I won't need to recompile on Ubuntu.
In the public interest, it is a good idea to have an Ubuntu package
ready with the patch.
I appreciate your effort in maintaining these packages!
I installed an Ubuntu 16.04 LTS on a VM, and fully updated it.
I then installed wxPython 3.0.2.0, and interestingly, there is no issue drawing elliptic arcs. Is your fix in?
The Fedora 24 pyinstaller-compiled program runs on Ubuntu, but the menu bar and toolbar do not look right, and I get tons of warnings from GTK, starting with:
Gtk-WARNING **: Theme parsing error: gtk.css:13:31: The style property GtkMenu:horizontal-padding is deprecated and shouldn’t be used anymore. It will be removed in a future version.
Running the Python code of my program on Ubuntu, looks just fine!
What’s the best approach to getting a binary to look right and work across the major Linux distros?
Ubuntu doesn't have the elliptic arc fix but perhaps the problem only affects the GTK3 build - Ubuntu uses GTK2.
I'm not sure about pyinstaller - I've never used it. Does just taking your Python source files and running them on both distributions work?

Yes, the native code runs fine on both, although visual differences exist:
Toolbar icons that don’t fit horizontally in the window are grouped into a pull-down menu.
On Ubuntu the icons are shown OK,
but on Fedora the pull-down list looks empty, although the tools are there and are clickable…
When the program window is larger than wx.Canvas size,
on Ubuntu the space outside the canvas has the color I gave it (same as on Windows),
but on Fedora it looks gray.
SpinCtrl up/down arrows are aligned horizontally on Fedora, but vertically on Ubuntu.

Could potentially bug in wxWidgets GTK+3 implementation? I've seen reports of similar things, I think.

Again, potentially a wxWidgets GTK+3 bug.

Is it supposed to be OK to run a GTK2 compiled binary (Ubuntu) on a
GTK3 system (Fedora)?
When I run my Ubuntu binary on Fedora, the first error is:
GdkPixbuf-WARNING **: Cannot open pixbuf loader module file
'/usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such
file or directory
Can I select which GTK to use, e.g. GTK2 on Fedora instead of GTK3?
It depends what you mean by binary. You're just talking about your pure wxPython code, right (.py files)? In that case, yes, it should be 100% portable. If you are talking about actual binary code, the answer is more complicated.
No, you can't generally select which GTK you want to use, as on Fedora the official wxPython package is built for GTK3 only. You could, of course, compile your own wxPython if you really wanted a GTK2 version.
