【正文】 cluding the basic drawing operations and the certain classes in the package: Container, Window, Panel, Dialog, and Frame. Best of all possible approaches Swing does not pletely follow the Java language as a platform route. Instead, it bines the best of both approaches by offering a bridge back to the native platforms. The mechanism for establishing this bridge is referred to as Pluggable LookandFeels (which is pretty close to the concept of themes, popular in the Linux munity). Each Swing ponent has a model of its functionality and a separate appearance (the lookandfeel), which can be set in advance or changed on the fly. Swing provides a Java lookandfeel (previously known as Metal), separate ones for the Windows and Motif platforms, and one for the Macintosh platform (as an extra option). The platform lookandfeels don39。s graphical capabilities. Various technologies, such as Swing, were introduced as optional extensions. With the Java 2 platform, most of these extensions have found their way into the core as part of the Java Foundation Classes (JFC). JFC refers to the entire set of graphical and user interface technologies included in the Java 2 platform, including AWT and Swing. In this article, we39。 the rest are currently optional extensions, but some of them will no doubt find their way into the core in the future. The other APIs in this area are Java 3D, Advanced Imaging, Image I/O, the Java Media Framework (JMF), and Speech. Java 3D The Java 3D API provides a set of objectoriented interfaces that support a simple, highlevel programming model, enabling developers to build, render, and control the behavior of 3D objects and visual environments. The API includes a detailed specification document and implementation for packages and . Advanced Imaging Operations covered by this specification enhance a user39。在 Java2 平臺上,這些擴展中的大部分都可以在平臺的核心中找到它們的一席之地,成為 Java 基礎類( Java Foundation Classes, JFC)的一部分。當然,這也是問題開始的地方。為了實現(xiàn)這個目標,本機組件必須盡量地丟棄。 Swing 為 Windows 平臺和 Motif 平臺分別提供一個 Java lookandfeel(以前稱為 Metal),同時為 Macintosh 平臺提供一個 Java lookandfeel(作為額外選項)。為了集成本機平臺的拖放功能,它也可以以一種平臺相關的方式運行。這樣安排的原因是:向后兼容。例如,(x,y,w,h)將在 (x,y)點上構造一個以寬為 w、高為 h 的矩形為邊界的橢圓,其中 x、 y、 w 和 h 都為浮點值。它們包括: 使用抗鋸齒處理和微調( hinting)以達到更好的輸出質量 可以使用系統(tǒng)安裝的所有字體 可以將對圖形對象的操作(旋轉、縮放、著色、剪切等等)應用到文本上。它包括的操作有對比度增強、剪切、縮放、幾何彎曲和頻率范圍處理。 這個綜合 API 被分成幾個規(guī)范: Java Speech API 規(guī)范( Java Speech API Specification, JSAPI) Java Speech API 程序員指南 Java Speech API 語法格式規(guī)范( Java Speech API Grammar Format Specification, JSGF) Java Speech API 標記語言規(guī)范( Java Speech API Markup Language Specification, JSML) 這個 API 沒有 Sun 公司的參考實現(xiàn),但是有許多第三方實現(xiàn),包括 Speech for Java(可以從 IBM alphaWorks 獲得),它使用 ViaVoice 來支持語音命令識別、聽寫和文本到語音的合成。 Image I/O 這種 API 定義了一種可讀 /寫不同格式圖像的可插式框架。 先進的字體度量功能,超過舊的 類中的相應功能 排版功能可以實現(xiàn)單詞換行和調整多行文本 多媒體選項: Java Media API( Java 媒體 API) Java Media API 是一套涵蓋廣泛的多媒體技術領域的資源。仿射轉換指的是平行線在轉換后還保持平行。 盡管在 語言的當前版本中,這個對象真是一個 Graphics2D 對象。讓我們看一個示例。相反,它們使用輕量級組件,有和本機組件一樣的外觀。如果不包含 X System Window 的調用,您就不能在 UNIX 上顯示一個窗口。但隨著復雜性的增加,情況就不一樣了,這只是因為組件的不同,而且在某些情況下,不管修正了多少錯誤,并且 AWT 的部件被重寫了多少次,它們總會表現(xiàn)得有一點不同。在本文中,我們將討論 JFC 的每個主要組件,并討論一些可選的擴展。s Guide Java Speech API Grammar Format Specification (JSGF) Java Speech API Markup Language Specification (JSML) There is no Sun reference implementation for this API, but there are numerous thirdparty implementations, including Speech for Java (available from IBM alphaWorks), which uses ViaVoice to support voicemand recognition, dictation, and texttospeech synthesis.
