XtSetArg __libmansuffix__ __xorgversion__ "XT FUNCTIONS"
NAME
XtSetArg, XtMergeArgLists - set and merge ArgLists
SYNTAX
#include <X11/Intrinsic.h>
int XtSetArg(Arg arg, String name, XtArgVal value);
ArgList XtMergeArgLists(ArgList args1, Cardinal num_args1, ArgList args2, Cardinal num_args2);
ARGUMENTS
arg 1i
Specifies the name-value pair to set.
args1 1i
Specifies the first
ArgList . args2 1i
Specifies the second
ArgList . num_args1 1i
Specifies the number of arguments in the first argument list.
num_args2 1i
Specifies the number of arguments in the second argument list.
name 1i
Specifies the name of the resource.
value 1i
Specifies the value of the resource if it will fit in an
XtArgVal or the address.
DESCRIPTION
The
XtSetArg function is usually used in a highly stylized manner to
minimize the probability of making a mistake; for example:
Arg args[20]; int n; n = 0; XtSetArg(args[n], XtNheight, 100); n++; XtSetArg(args[n], XtNwidth, 200); n++; XtSetValues(widget, args, n);
Alternatively, an application can statically declare the argument list and use XtNumber :
static Args args[] = {
{XtNheight, (XtArgVal) 100},
{XtNwidth, (XtArgVal) 200},
};
XtSetValues(Widget, args, XtNumber(args));
Note that you should not use auto-increment or auto-decrement within the first argument to XtSetArg . XtSetArg can be implemented as a macro that dereferences the first argument twice.
The XtMergeArgLists function allocates enough storage to hold the combined ArgList structures and copies them into it. Note that it does not check for duplicate entries. When it is no longer needed, free the returned storage by using XtFree .
