I'm building a GUI for a project at school. My button structure is:
typedef struct 
{
int x,y,w,h;
void (*action) (void);
int raised;
char *text;
int clickable;
} Tbutton;

I initialise a button as
Tbutton load={215,60,70,20,NULL,1,"Load",0};
here the function is NULL because I haven't implemented it yet :)
Anyways, I have an array of buttons. (but)
If I say
but[number].(*action)(); I get a parse error before "("
but if I say
void (*thing)();
thing=but[number].action;
(*thing) ();
it works and calls the right function. Why?
