Hi,
Thanks.
IupGetAttributes is not a very safe function. I wouldn't recommend its use
unless strictly necessary. We kept it for backward compatibility with old
applications.
Regarding the callbacks in that case, are you using IupSetCallback or
IupSetAttribute+IupSetFunction?
Best,
Scuri

Subject: [Iup-users] IupGetAttributes
Gentlemen:
First of all - Thank You for the excellent application and the beautiful,
easy to read, code.
I am on Linux Ubuntu 13.04 using the source version of IUP 3.8
I am working on porting IUP to python using the Python CFFI which is modeled
on the Lua CFFI.
I was trying to use the function char* IupGetAttributes(Ihandle *ih) from
source file iup_attrib.c
in my python code and got the following unexpected result.
The Interface Element that I am trying to dump the attributes on has the
following attributes set
Callbacks on ACTION and K_ANY
SIZE = 200x
this is a hex dump of the returned buffer
41 43 54 49 4F 4E 3D 22 55 48 89 E5 48 83 EC 30 ACTION=" UH..H..0

It seems the test for non string pointers is never tripping
I dug around with iupAttribIsPointer and iupClassObjectAttribIsNotString and
could not get them to return True so the non string data could be output
to a string format.
I thought I would ask for advice before I continued to dig around in the
code.
Thanking you in advance for you time,
Richard
