Method ilcd.Extra.setMessageNamePrefix

static void setMessageNamePrefix(String prefix)

Throws:

_INSERT_METHOD_SIGNATURE_HERE_

Parameter	Range	Description
prefix	up to 4 ASCII chars (0x01 .. 0xFF)	string to be prefix

Sets a prefix of case-sensitive string characters, which will be put in front of any subsequently sent message name (see Draw.writeTextMessage(int)).

This functionality can be used to support multiple languages without conditional methods or macros. For example, if the message names for the English language are prefixed with "en_" and for the German language with "de_", the method

Draw.writeTextMessage("message");

would display the message "en_message" or "de_message", dependent on the prior defined message prefix.
When addressing text messages by index, an offset can be used to realize language switching. (see Extra.setMessageOffset(int)).
Remove any previously set Message Name Prefix by entering an empty string as prefix:

Extra.setMessageNamePrefix("");
The default value for prefix is an empty string. It will be automatically set to default on startup and by the methods General.resetAll() or General.rebootPanelController() if the "Extras on Reset" option on the "Settings" page of iLCD Manager XEJoC Manager is set to "Clear". Selecting "Keep" allows for using the reset methods without loosing e.g. the selected language.

Example

Extra.setMessageNamePrefix("en_");

Set the message name prefix to "en_" and will subsequently only call a message that start with these characters.
