Update libraries to latest stable released version (except gnomecanvasmm, which is strangely packaged...). Fixes building (at least here). git-svn-id: svn://localhost/ardour2/trunk@2790 d708f5d6-7413-0410-9779-e7cbd77b26cf

/** The Clipboard object represents a clipboard of data shared between different processes or between
|
|
* different widgets in the same process. Each clipboard is identified by a name encoded as a GdkAtom. *
|
|
* (Conversion to and from strings can be done with gdk_atom_intern() and gdk_atom_name().) The default
|
|
* clipboard corresponds to the "CLIPBOARD" atom; another commonly used clipboard is the "PRIMARY" clipboard,
|
|
* which, in X, traditionally contains the currently selected text.
|
|
*
|
|
* To support having a number of different formats on the clipboard at the same time, the clipboard mechanism
|
|
* allows providing callbacks instead of the actual data. When you set the contents of the clipboard, you can
|
|
* either supply the data directly (via functions like set_text()), or you can supply a callback
|
|
* to be called at a later time when the data is needed (via set().) Providing a callback also avoids having to
|
|
* make copies of the data when it is not needed.
|
|
*
|
|
* Requesting the data from the clipboard is essentially asynchronous. If the contents of the clipboard are
|
|
* provided within the same process, then a direct function call will be made to retrieve the data, but if they
|
|
* are provided by another process, then the data needs to be retrieved from the other process, which may take
|
|
* some time. To avoid blocking the user interface, the call to request the selection, request_contents() takes
|
|
* a callback that will be called when the contents are received (or when the request fails.) If you don't want
|
|
* to deal with providing a separate callback, you can also use wait_for_contents(). This runs the
|
|
* GLib main loop recursively waiting for the contents. This can simplify the code flow, but you still have to
|
|
* be aware that other callbacks in your program can be called while this recursive mainloop is running.
|
|
*
|
|
* Along with the functions to get the clipboard contents as an arbitrary data chunk, there are also functions
|
|
* to retrieve it as text, request_text() and wait_for_text(). These functions take
|
|
* care of determining which formats are advertised by the clipboard provider, asking for the clipboard in the
|
|
* best available format and converting the results into the UTF-8 encoding.
