Example

This program segment displays a string stored in the variable descriptionString.

ac = 0;
 XtSetArg (al[ac], DtNhelpType,   DtHELP_TYPE_DYNAMIC_STRING); ac++;
 XtSetArg (al[ac], DtNstringData, (char *)descriptionString);   ac++;
 XtSetValues (quickHelpDialog, al, ac);
 XtManageChild (quickHelpDialog);

If the string is no longer needed within the application, the memory can be freed, because the help dialog makes its own copy of the data.

 XtFree (descriptionString);
