public class Selection


The X selection mechanism provides a way to transfer arbitrary chunks of data between programs. A selection is a essentially a named clipboard, identified by a string interned as a GdkAtom. By claiming ownership of a selection, an application indicates that it will be responsible for supplying its contents. The most common selections are PRIMARY and CLIPBOARD.

The contents of a selection can be represented in a number of formats, called targets. Each target is identified by an atom. A list of all possible targets supported by the selection owner can be retrieved by requesting the special target TARGETS. When a selection is retrieved, the data is accompanied by a type (an atom), and a format (an integer, representing the number of bits per item). See Properties and Atoms for more information.

The functions in this section only contain the lowlevel parts of the selection protocol. A considerably more complicated implementation is needed on top of this. GTK+ contains such an implementation in the functions in gtkselection.h and programmers should use those functions instead of the ones presented here. If you plan to implement selection handling directly on top of the functions here, you should refer to the X Inter-client Communication Conventions Manual (ICCCM).
