XtSetArg(3Xt) X11R5 XtSetArg(3Xt)NAME
XtSetArg, XtMergeArgLists - set and merge ArgLists
SYNTAX
XtSetArg(arg, name, value)
Arg arg;
String name;
XtArgVal value;
ArgList XtMergeArgLists(args1, num_args1, args2, num_args2)
ArgList args1;
Cardinal num_args1;
ArgList args2;
Cardinal num_args2;
ARGUMENTS
arg Specifies the name-value pair to set.
args1 Specifies the first
args2 Specifies the second
num_args1 Specifies the number of arguments in the first argument list.
num_args2 Specifies the number of arguments in the second argument
list.
name Specifies the name of the resource.
value Specifies the value of the resource if it will fit in an or
the address.
DESCRIPTION
The 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
static Args args[] = {
{XtNheight, (XtArgVal) 100},
{XtNwidth, (XtArgVal) 200}, }; XtSetValues(Widget, args, XtNum‐
ber(args));
Note that you should not use auto-increment or auto-decrement within
the first argument to can be implemented as a macro that dereferences
the first argument twice.
The function allocates enough storage to hold the combined 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
