Multiple window handling
Hi!!
I'm trying to program an application which have multiple windows and
is capable of executing method defined inside class of one another, i
tries a simpel frame work here and am creating Toplevel inside method
as the new window to be genereated, and again want another window to
be loaded when the widget inside toplevel is executed as
necessary..but am feeling lost to either create a class for such new
window or write function again..
also, when running clearentry() it is not working...have i missed
something here..
Programming with multiple window is main task for me..so how it can be
done???

Re: How to access an Array and a struct within a struct wrapped by Swig ?
Hi,
If you have struct defined in .h file then it's ok or can dea easyily
with struct written with .i file,
in .h file,
struct def
{
int a;
char name[10];
};
can be referenced as
>>strvar=new_def() //now strvar is your
object for struct def
and can access a and name as, get and
set for individual member see,
>>def_a_set(strvar,10)
>>def_a_get(strvar) will return 10.
or you can define struct as,
typedef struct
{
int sage;
}coll;
within .h file and access similarly.

Wrapping C with Python
Hi!!
I tried wrapping a simple C code suing SWIG to Python, but am having
problem,
my .c file is,
Step 1:
example.c
--
double val=3.0;
int fact(int n)
{
if(n<=1)
return 1;
else
return n*fact(n-1);
}
int mod(int x, int y)
{
return (x%y);
}
Step 2:
I then created interface file as.
example.i
--
%module example
%{
%}
extern int fact(int n);
extern int mod(int x,int y);
Step 3:
I compiled the .i file with SWIG,
c:\python25\swig> swig -
python example.i
It creates example.py and example_wrap.c
Step 4:
I compiled example.c and example_wrap.c individually
c:\python25\mingw\bin> gcc -c example.c (it create
example.o)
c:\python25\mingw\bin> gcc -c example_wrap.c -Ic:
\python25\include(it create example_wrap.o)
Step 5:
building .pyd for windows,
c:\python25\mingw\bin> gcc -shared *.o -o _example.pyd -Lc:
\python25\libs -lpython25 (it creates _example.pyd)
Then, i imported example module by palcing it in python25 directory,
it get's imported but i'm not able to use function, when i called
>>>print example.fact(4)
>>>print example.mod(4,2)
It is nither showing any error nor message...
even i tried simple void fact() by printf inside .c file and is not
showing ...
hope for help...
