# Gtk2::UniqueMessageData(3pm)

Message container for Gtk2::UniqueApp

## NAME

Gtk2::UniqueMessageData - Message container for Gtk2::UniqueApp

## DESCRIPTION

This class wraps the messages passed to a `"Gtk2::UniqueApp"`. Usually you will never create a message with the Perl API has this is done by the bindings on your behalf. Since messages are only read through the Perl bidings the methods for setting the contents of a message are not accessible.

What's important to understand is that a `"Gtk2::MessageData"` is a generic container for all message types (text, data, filename and uris). There's no way to query what kind of message a `"Gtk2::MessageData"` holds. It is the responsability of each application to know it in advance and to call the proper get methods. If you don't call the proper get method you could have a segmentation fault in your application as the C library will try to unmarshall the message with the wrong code.

You can retrieve the data set using `"Gkt2::MessageData::get()"`, `"Gkt2::MessageData::get_text()"` or `"Gkt2::MessageData::get_uris()"`.
