* This class is the abstract superclass of all actual |
|
70 |
* implementations of the Abstract Window Toolkit. Subclasses of |
|
35667 | 71 |
* the {@code Toolkit} class are used to bind the various components |
2 | 72 |
* to particular native toolkit implementations. |
73 |
* <p> |
|
74 |
* Many GUI events may be delivered to user |
|
75 |
* asynchronously, if the opposite is not specified explicitly. |
|
76 |
* As well as |
|
77 |
* many GUI operations may be performed asynchronously. |
|
78 |
* This fact means that if the state of a component is set, and then |
|
79 |
* the state immediately queried, the returned value may not yet |
|
80 |
* reflect the requested change. This behavior includes, but is not |
|
81 |
* limited to: |
|
82 |
* <ul> |
|
83 |
* <li>Scrolling to a specified position. |
|
35667 | 84 |
* <br>For example, calling {@code ScrollPane.setScrollPosition} |
85 |
* and then {@code getScrollPosition} may return an incorrect |
|
2 | 86 |
* value if the original request has not yet been processed. |
21957 | 87 |
* |
2 | 88 |
* <li>Moving the focus from one component to another. |
89 |
* <br>For more information, see |

2 | 111 |
* the "glue" that joins the platform-independent classes in the |
35667 | 112 |
* {@code java.awt} package with their counterparts in |
113 |
* {@code java.awt.peer}. Some methods defined by |
|
114 |
* {@code Toolkit} query the native operating system directly. |

* loaded by the java.* classes, which do not necessarily know the |
|
1338 |

* would be to provide a separate library which defines java.awt.* |
