Markdown not shown on Linux

[CsatiZoltan]

Markdown files are not rendered on Linux. The title of the wxwidgets window is shown but not the content. No exception is thrown. I observed that both the LoadURL method

imagepy/imagepy/ui/mkdownwindow.py

Line 54 in c0804fa

if url != '': self.wv.LoadURL(url)

and the SetPage method

imagepy/imagepy/ui/mkdownwindow.py

Line 55 in c0804fa

else: self.wv.SetPage(cont, url)

have no effect.

I am not sure whether it's related but clicking on the icons (Snap, Load, >>, and the user-defined buttons) in a Workflow has no effect, as if the callback was not called. However, the mouse-over works: the documentation box is updated.

I confirm that both of these issues persist on Linux but not on Windows. This must be an issue with wxpython.

I did not bind any event on "Snap, Load, >>" yet, [snap] is designed to snap the current status, and [load] to reload the status snapped befor.

about the markdown not show on linux. may be because the 'math supportting' befor, I found the js did not run withing the SetPage, So I write the html to a file (in imagepy/data/index.html, and delete it when form loaded). so does your path need a sudo?

[CsatiZoltan]

It's OK that there is no action for Snap, Load and >>, but there is also no effect (on Linux) when clicking on the button created via the .wf file.

Yes, I observed that you write into imagepy/data/index.html, but the file is successfully created -- I cheked. Also, my path is in /home, where no sudo is needed.

I would have a look when I use linux next time.

I test markdown works on Mac. did you install python-markdown-math?
try this wxpython's webview demo if it is OK, tell me. and If this does not work, give an issue to the wxphoenix.

[CsatiZoltan]

Unfortunately, I couldn't try it because the demo file throws an error:

'WebView' has no attribute 'MSWSetEmulationLevel'

This is because I have wxPython version 4.0.7.post2, and MSWSetEmulationLevel requires version 4.1. at least: wxWidgets/Phoenix#1434 (comment)
No conda repository contains 4.1. and the existing wheels are not compatible with my system. Installing wyPython from the sources seems to be painful. What do you recommend?
