This is the problem in thuban but I have an idea.

I have seen the sample in WxPythonOSX and I check samples/pySketch

In terminal I enter:
% pythonw pysketch.pyw

and the program works with all icons inside the window.

Thuban usually run in Linux (GTK) and Windows 
system with menu in a floating window: in this 
window there are the icons (source mainwindow.py, 
I think). OS X is different: the menu is up not 
in a floating window and the icons are lost. 
These icons must to be in a floating window like 
a LEGEND (see LEGENDA window at 
The source is in legend.py: the normal layer 
icons are there. If I select Zoom In from Map 
menu the icon is showed at the selected window 
but normally is hide.

This bug is fixed.

Now works: this is the config

I have produced a Thuban SVG file: it's OK but 
the lines are very big, more than 1 point. OK I 
can change them in my vector program but perhaps 
it's possible to write a smaller size in SVG

I have seen other Free and Commercials sw and Thuban is faster.
