Following is my code.
<br />
#include <Xm/Xm.h><br />
#include <Xm/ComboBox.h></p>
<p>/* the list of colors */<br />
char *colors[] = { "red", "green", "blue", "orange", "purple",<br />
"pink", "white", "black", "yellow" };</p>
<p>main (int argc, char *argv[])<br />
{<br />
Widget toplevel, combo;<br />
XtAppContext app;<br />
Arg args[4];<br />
int count = XtNumber (colors);<br />
int i, n;<br />
XmStringTable str_list;</p>
<p> /* initialize the toolkit */<br />
XtSetLanguageProc (NULL, NULL, NULL);<br />
toplevel = XtVaOpenApplication (&app, "Demos", NULL, 0, &argc, argv, NULL,<br />
sessionShellWidgetClass, NULL);<br />
/* create the List item */<br />
str_list = (XmStringTable) XtMalloc (count * sizeof (XmString *));</p>
<p> for (i = 0; i < count ; i++)<br />
str_list[i] = XmStringCreateLocalized (colors[i]);</p>
<p> /* create the combox */<br />
n = 0;<br />
XtSetArg (args[n], XmNitems, str_list); n++;<br />
XtSetArg (args[n], XmNitemCount, count); n++;<br />
combo = XmCreateDropDownList (toplevel, "combo", args, n);</p>
<p> for (i = 0; i < n; i++)<br />
XmStringFree (str_list[i]);<br />
XtFree ((XtPointer)str_list);</p>
<p> XtManageChild (combo);<br />
XtRealizeWidget (toplevel);<br />
XtAppMainLoop (app);<br />
}<br />

compile is ok.
and ,when I run it.the following warning is out.
<br />
Warning:<br />

Character '\162' not supported in font. Discarded.</p>
