XtDisplayStringConversionWarning(3) XT FUNCTIONS XtDisplayStringConversionWarning(3)NAME
XtDisplayStringConversionWarning - issue a conversion warning message
void XtDisplayStringConversionWarning(Display* display, String from_value, to_type);
display Specifies the display connection with which the conversion is associated.
Specifies the string that could not be converted.
to_type Specifies the target representation type requested.
The XtDisplayStringConversionWarning function issues a warning message using XtAppWarningMsg with name ``conversionError'', type
``string'', class ``XtToolkitError, and the default message string ``Cannot convert "from_value" to type to_type''.
To issue other types of warning or error messages, the type converter should use XtAppWarningMsg or XtAppErrorMsg.

XtAppWarningMsg - call the high-level warning handler.
void XtAppWarningMsg(app_context, name, type, class , default, params, num_params)
Specifies the application context.
name Specifies the general kind of error.
type Specifies the detailed name of the error.
class Specifies the resource class.
default Specifies the default message to use if no message is found in the database.
params Specifies an array of values to be inserted into the message.
Specifies the number of elements in params.
XtAppWarningMsg() passes all of its arguments except app_context to the installed high-level warning handler. The default high-level warn-
ing handler is _XtDefaultWarningMsg(). It calls XtAppGetErrorDatabaseText() to lookup a message of the specified name, type, and class in
the error database. If no such message is found, XtAppGetErrorDatabaseText() returns the specified default message. In either case,
_XtDefaultWarningMsg() does a printf-style substitution of params into the message, and passes the resulting text to the low-level warning
handler by calling XtWarning().
See XtAppGetErrorDatabaseText() for details on how messages are looked up in the error database.
To report fatal error messages and exit, use XtAppErrorMsg(). To change the high-level warning handler, use XtAppSetWarningMsgHandler().
Note that the num_params argument to this function is a Cardinal *, not a Cardinal.
Although the Intrinsics interface allows separate error and warning handlers for each application context, most implementations will sup-
port only a single set of handlers. When a new handler is installed, it will be used in all application contexts.
The following code is from XtDisplayStringConversionWarning():
Cardinal num_params = 2;
params = (String)from;
params = (String)toType;
XtNconversionError, "string", XtCXtToolkitError,
"Cannot convert string to type %s",
