/** |

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 |
|
35667 | 32 |
* for convenience. Common X Atoms like {@code XA_WM_NAME} are used to communicate with the |
2 | 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 |
|
35667 | 36 |
* by the XServer and an {@code XAtom} object is returned. An {@code XAtom} can also be created |
37 |
* by using a pre-exisiting atom like {@code XA_WM_CLASS}. A {@code display} has to be specified |
|
38 |
* in order to create an {@code XAtom}. <p> <p> |
|
2 | 39 |
* |
35667 | 40 |
* Once an {@code XAtom} instance is created, you can call get and set property methods to |
2 | 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> |
|
35667 | 45 |
* <pre>{@code |
46 |
* XAtom xa = new XAtom(display,XAtom.XA_WM_NAME); |
|
47 |
* xa.setProperty(window,"Hello World"); |
|
48 |
* }</pre> |
|
49 |
* <p> |
|
50 |
* <p> |
|
51 |
* To get the cut buffer: |
|
52 |
* <pre>{@code |
|
53 |
* XAtom xa = new XAtom(display,XAtom.XA_CUT_BUFFER0); |
|
54 |
* String selection = xa.getProperty(root_window); |
|
55 |
* }</pre> |
