+
+ Properties / Entry arguments:
+ text-label: The value of this string indicates the property / entry-arg
+ that contains the string to place in the entry
+ <xxx> (actual name is the value of text-label): contains the string to
+ place in the entry.
+ <text>: The text to place in the entry (overrides the above mechanism).
+ This is useful when the text is constant.
Example node:
message = "a message directly in the node"
};
+ or just:
+
+ text {
+ size = <8>;
+ text = "some text directly in the node"
+ };
+
The text is not itself nul-terminated. This can be achieved, if required,
by setting the size of the entry to something larger than the text.
