Detailed Description

Copy and paste feature implementations.

Implements the following functionality a. select, copy/cut and paste b. clipboard c. drag and drop in order to share data across application windows.

Contains functions to select text or a portion of data, send it to a buffer, and paste the data into a target.

elm_cnp provides a generic copy and paste facility based on its windowing system. It is not necessary to know the details of each windowing system, but some terms and behavior are common. Currently the X11 window system is widely used, and only X11 functionality is implemented.

In X11R6 window system, CopyPaste works like a peer-to-peer communication. Copying is an operation on an object in an X server. X11 calls those objects 'selections' which have names. Generally, two selection types are needed for copy and paste: The Primary selection and the Clipboard selection. Primary selection is for selecting text (that means highlighted text). Clipboard selection is for explicit copying behavior (such as ctrl+c, or 'copy' in a menu). Thus, in applications most cases only use the clipboard selection. As stated before, taking ownership of a selection doesn't move any actual data. Copying and Pasting is described as follows:

1. Copy text in Program A : Program A takes ownership of the selection
2. Paste text in Program B : Program B notes that Program A owns the selection
3. Program B asks A for the text
4. Program A responds and sends the text to program B
5. Program B pastes the response More information is on

TODO: add for other window system.
