| /** |
| * XAtom is a class that allows you to create and modify X Window properties. |
| * An X Atom is an identifier for a property that you can set on any X Window. |
| * Standard X Atom are defined by X11 and these atoms are defined in this class |
| * for convenience. Common X Atoms like <code>XA_WM_NAME</code> are used to communicate with the |
| * Window manager to let it know the Window name. The use and protocol for these |
| * atoms are defined in the Inter client communications converntions manual. |
| * User specified XAtoms are defined by specifying a name that gets Interned |
| * by the XServer and an <code>XAtom</code> object is returned. An <code>XAtom</code> can also be created |
| * by using a pre-exisiting atom like <code>XA_WM_CLASS</code>. A <code>display</code> has to be specified |
| * in order to create an <code>XAtom</code>. <p> <p> |
| * |
| * Once an <code>XAtom</code> instance is created, you can call get and set property methods to |
| * set the values for a particular window. <p> <p> |
| * |
| * |
| * Example usage : To set the window name for a top level: <p> |
| * <code> |
| * XAtom xa = new XAtom(display,XAtom.XA_WM_NAME); <p> |
| * xa.setProperty(window,"Hello World");<p></code> |
| *<p> |
| *<p> |
| * To get the cut buffer :<p> |
| * <p><code> |
| * XAtom xa = new XAtom(display,XAtom.XA_CUT_BUFFER0);<p> |
| * String selection = xa.getProperty(root_window);<p></code> |
