61 |
* This class is the abstract superclass of all actual |
|
62 |
* implementations of the Abstract Window Toolkit. Subclasses of |
|
63 |
* the <code>Toolkit</code> class are used to bind the various components |
|
64 |
* to particular native toolkit implementations. |
|
65 |
* <p> |
|
66 |
* Many GUI events may be delivered to user |
|
67 |
* asynchronously, if the opposite is not specified explicitly. |
|
68 |
* As well as |
|
69 |
* many GUI operations may be performed asynchronously. |
|
70 |
* This fact means that if the state of a component is set, and then |
|
71 |
* the state immediately queried, the returned value may not yet |
|
72 |
* reflect the requested change. This behavior includes, but is not |
|
73 |
* limited to: |
|
74 |
* <ul> |
|
75 |
* <li>Scrolling to a specified position. |
|
76 |
* <br>For example, calling <code>ScrollPane.setScrollPosition</code> |
|
77 |
* and then <code>getScrollPosition</code> may return an incorrect |
|
78 |
* value if the original request has not yet been processed. |
|
| 21957 | 79 |
* |
| 2 | 80 |
* <li>Moving the focus from one component to another. |
81 |
* <br>For more information, see |

|
94 |
* <code>setLocation</code> on a <code>Window</code>, |
|
95 |
* <code>Frame</code> or <code>Dialog</code> are forwarded |
|
96 |
* to the underlying window management system and may be |
|
97 |

* <p> |
|
101 |
* Most applications should not call any of the methods in this |
|
102 |
* class directly. The methods defined by <code>Toolkit</code> are |
|
103 |
* the "glue" that joins the platform-independent classes in the |
|
104 |
* <code>java.awt</code> package with their counterparts in |
|
105 |
* <code>java.awt.peer</code>. Some methods defined by |
|
106 |
* <code>Toolkit</code> query the native operating system directly. |

* WARNING: This is a temporary workaround for a problem in the |
|
1614 |
* way the AWT loads native libraries. A number of classes in the |
|
1615 |
* AWT package have a native method, initIDs(), which initializes |
|
1616 |
* the JNI field and method ids used in the native portion of |
|
1617 |
* their implementation. |
|
1618 |
* |
|
1619 |
* Since the use and storage of these ids is done by the |
|
1620 |
* implementation libraries, the implementation of these method is |
|
1621 |
* provided by the particular AWT implementations (for example, |
|
1622 |
* "Toolkit"s/Peer), such as Motif, Microsoft Windows, or Tiny. The |
|
1623 |
* problem is that this means that the native libraries must be |
|
1624 |
* loaded by the java.* classes, which do not necessarily know the |
|
1625 |
* names of the libraries to load. A better way of doing this |
|
1626 |
* would be to provide a separate library which defines java.awt.* |
|
1627 |
* initIDs, and exports the relevant symbols out to the |
|
1628 |
* implementation libraries. |
|
1629 |
* |
|
1630 |
* For now, we know it's done by the implementation, and we assume |
|
1631 |
* that the name of the library is "awt". -br. |
|
1632 |
* |
|
1633 |
* If you change loadLibraries(), please add the change to |
|
1634 |
* java.awt.image.ColorModel.loadLibraries(). Unfortunately, |
|
1635 |
* classes can be loaded in java.awt.image that depend on |
|
1636 |
* libawt and there is no way to call Toolkit.loadLibraries() |
