function onTxError(error) {
    console.error("TX Text Control error:", error.msg);
    error.handled = true;
}

TXTextControl.inputFormat.getUnderline(
    function(result) {
        if (result) {
            console.log("get underline is available.");
        } else {
            console.warn("get underline is not available in the current document state.");
        }
    },
    onTxError
);
