+1 for going ahead with the splash screen. Also, maybe not for RC2 but soon, it would make more sense and be more like other programs to have the splash screen come first, followed by the startup screen. Michael __ C.

[GRASS-dev] Howto use a Python function as error handler in libgis
Dear developers,
i am trying to register a Python function as error handler callback
using ctypes in libgis.
I use this code in the temporal framework:
{{{
def error_handler(data):
pass
CALLBACK = CFUNCTYPE(None, c_void_p)
CALLBACK.restype = None
CALLBACK.argtypes = c_void_p
cerror_handler = CALLBACK(error_handler)
libgis.G_add_error_handler(cerror_handler, POINTER(None))
}}}
Unfortunately i get this error:
{{{
Traceback (most recent call last):
File /usr/lib/python2.7/multiprocessing/process.py, line 258, in _bootstrap
self.run()
File /usr/lib/python2.7/multiprocessing/process.py, line 114, in run
self._target(*self._args, **self._kwargs)
File
/home/soeren/src/grass7.1/grass_trunk/dist.x86_64-unknown-linux-gnu/etc/python/grass/temporal/c_libraries_interface.py,
line 759, in c_library_server
libgis.G_add_error_handler(cerror_handler, POINTER(None))
ArgumentError: argument 1: type 'exceptions.TypeError': expected
CFunctionType instance instead of CFunctionType
}}}
Does anyone know what the correct way is to register a Python function
as error handler in libgis?
Any help is highly welcome.
Best regards
Soeren

Using the example code here with the 400K version of the splash screen works perfectly. yes, but on the wiki page, they say: Although this example will work fine, it overlooks the main reason programmers add a splash screen; to give the user feedback while a program is loading. It first displays splash screen for 1 second and then start to load the main frame. So this would basically make the gui start even longer. I don't have problems as you describe so it's difficult to test anything. I still don'y understand, did you have the same problems with the old splash screen?
