/**
|
|
* 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} 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} object is returned. An {@code XAtom} can also be created
|
|
* by using a pre-exisiting atom like {@code XA_WM_CLASS}. A {@code display} has to be specified
|
|
* in order to create an {@code XAtom}. <p> <p>
|
|
*
|
|
* Once an {@code XAtom} 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>
|
|
* <pre>{@code
|
|
* XAtom xa = new XAtom(display,XAtom.XA_WM_NAME);
|
|
* xa.setProperty(window,"Hello World");
|
|
* }</pre>
|
|
* <p>
|
|
* <p>
|
|
* To get the cut buffer:
|
|
* <pre>{@code
|
|
* XAtom xa = new XAtom(display,XAtom.XA_CUT_BUFFER0);
|
|
* String selection = xa.getProperty(root_window);
|
|
* }</pre>
