我现在装了rc1,好像多出了个preferences,里面多了个语言选择.
是不是Qt的这些工具要出中文版了?

加入了QtScript和SSL是这好东西。
还发现加入了QWizard/QWizardPage类，这样用来构造向导式的应用就方便得多了。

哎，本来说我也来说下，结果被你们抢现了。
我要说的好处是现在FC下的QT4。3。0把显示不了中文的问题给解决了。
我现在FC7，QT4。3。0，今天突然发现运行的程序终于出现了中文。。。不会再出现以前的［］了
就是字体很难看，全是小楷。。。。。

Main Window Styles
The main window classes now provide support for different main window paradigms, such as those found in Visual Studio or KDevelop.
Dock widgets occupying the same area can now be arranged in horizontal, vertical or collapsible tabs. Collapsible tabs are oriented according to the location of dock widgets around the main window's central area. suitable


API improvements to QDockWidget enable dock widgets to be given custom title bars and window styles, and also include support for vertical title bars.

Additionally, support for animations has been extended to tool bars, resulting in more sophisticated effects when tool bars and dock widgets are rearranged. See the Main Window demonstration for an extensive tour of these new features.
QtScript - Application Scripting with ECMAScript
This release introduces the QtScript module, providing an script engine for the ECMAScript language, based on the ECMA-262 standard, that is designed to enable easier integration of scripting facilities into end-user applications.

Scripts access application functionality via QObjects that are specifically created and exposed by each application. Information about the available child object ..

版本变更的中文翻译已经出来了
• 加强对Windows Vista™ 本地应用的支持
• QtScript 集成的ECMA 标准脚本引擎
• 加强对SSL（安全套接字层）通讯的支持
• 使用改进的OpenGL® 引擎，更快，更高质量地绘制3D 图形
• 更加灵活的主窗口架构
• 使用新一代SVG 文件，能渲染并生成SVG矢量图形图象
• 改进了Qtopia Core，包括新字体系统和加强了对OpenGL ES 的支持
加强了对Vista 本地应用开发的支持
增加了对Vista 风格、控制和动画的综合支持，从而Qt开发者能在下一代Windows 平台上开发出具有良好外观和感觉的应用。有了Qt 4.3, 基于Qt的应用现在已经完全符合Vista的风格准则，而且还利用了最新的Vista 创新。实际上，Qt Linguist 已经凭借4.3 版本获得了Vista 认证，标明它已经满足了微软Vista 兼容性准则的要求。
奇趣科技开发工具产品总监Naren Karattup 说道，“奇趣科技会不断努力使得跨平台软件开发更容易，更有力。我们在这方面的成就表现在Qt 4.3 Linguist 已经获得了Vista 认证。有了Qt 4.3，在所有主要操作系统上，创造出具有本地外观和感觉的应用将不再有障碍。除Linux 和Mac平台之外，开发者还可以轻松地把开发选定在为Vista 和以前的Windows 版本之上。”
Qt 4.3集成了新的ECMA脚本引擎
Qt 4.3 中加入了与ECMA标准兼容的全新脚本引擎QtScript。QtScript与Qt 创新的信号-槽机制（Signals and Solts mechanism）集成，可更方便地进行对象之间的通信，QtScript还集成了Qt应用中的C＋＋和脚本编码。QtScript作为Qt 4.3桌面版的部分， 可供Qt商业客户使用；作为Qt 开源版的部分时，供开源开发者使用。QtScript是基于ECMA脚本（Java脚本）最通用版本－ECMA Standard 262之上的。
