SigC::convert
|
|
-------------
|
|
convert() alters a Slot by assigning a conversion function
|
|
which can completely alter the parameter types of a slot.
|
|
|
|
Only convert functions for changing with same number of
|
|
arguments is compiled by default. See examples/custom_convert.h.m4
|
|
for details on how to build non standard ones.
|
|
|
|
Sample usage:
|
|
int my_string_to_char(Callback1<int,const char*> *d,const string &s)
|
|
int f(const char*);
|
|
string s=hello;
|
|
|
|
|
|
Slot1<int,const string &> s2=convert(slot(f),my_string_to_char);
|
|
s2(s);
|
|
