| 29 | * XAtom is a class that allows you to create and modify X Window properties. |
| 30 | * An X Atom is an identifier for a property that you can set on any X Window. |
| 31 | * Standard X Atom are defined by X11 and these atoms are defined in this class |
| 32 | * for convenience. Common X Atoms like <code>XA_WM_NAME</code> are used to communicate with the |
| 33 | * Window manager to let it know the Window name. The use and protocol for these |
| 34 | * atoms are defined in the Inter client communications converntions manual. |
| 35 | * User specified XAtoms are defined by specifying a name that gets Interned |
| 36 | * by the XServer and an <code>XAtom</code> object is returned. An <code>XAtom</code> can also be created |
| 37 | * by using a pre-exisiting atom like <code>XA_WM_CLASS</code>. A <code>display</code> has to be specified |
| 38 | * in order to create an <code>XAtom</code>. <p> <p> |
| 39 | * |
| 40 | * Once an <code>XAtom</code> instance is created, you can call get and set property methods to |
| 41 | * set the values for a particular window. <p> <p> |
| 42 | * |
| 43 | * |
| 44 | * Example usage : To set the window name for a top level: <p> |
| 45 | * <code> |
| 46 | * XAtom xa = new XAtom(display,XAtom.XA_WM_NAME); <p> |
| 47 | * xa.setProperty(window,"Hello World");<p></code> |
| 48 | *<p> |
| 49 | *<p> |
| 50 | * To get the cut buffer :<p> |
| 51 | * <p><code> |
| 52 | * XAtom xa = new XAtom(display,XAtom.XA_CUT_BUFFER0);<p> |
| 53 | * String selection = xa.getProperty(root_window);<p></code> |
