编程API

　　当图片创建程序被用于交互式绘制设计时，编程API可为程序提供一种与程序中的绘制进行互动的方法。API是工具包中第二重要的元素。当绘制功能内置于一个应用程序时，它能使您访问在创建程序中创建的对象。

　　工具包为在应用程序中部署工具包图片提供了大量的本地编程存储器，包括C/C++ 以及Java、Unix、Linux以及Windows：一个Motif/Gtk/Qt widget、一个MFC 类, Windows自定义控制、一个Java bean 以及类库、一个ActiveX Control等。点这里以获取更多关于编程存储器以及部署选项的信息。

　　开发人员只需使用一个简单的SetResource功能调用或程序就能设置任意的基于编程API资源结果的绘制资源。程序员只需知道给出资源的名称，而不需要知道如FillColor等的直观默认设置或任何资源的自定义名称。

　　编程API可用于在运行时修改绘制资源以及为实时更新提供动态数据。通过提供新的资源值，应用程序只需注意程序本身。并且工具包引擎会处理低级别图片与损坏修复的所有细节。更新通过数据驱动，所以如果数据不改变就不需要消耗CPU时间。

 　　API同样能用来处理用户互动，如对象选择或与按键的交互以及动态颜色滑块与控制组件。不管屏幕尺寸大小或变焦状态，对象选择通过工具包进行透明处理。每当选择感兴趣的对象时，会触发具有所有选项信息的程序回调。

Programming API

　　While the Graphics Builder is used for interactive design of drawings, the Programming API provides a way for the program to interact with the drawing from a program. The API is the second crucial element of the Toolkit, and provides programming access to objects created in the Builder when the drawing is embedded into an application.

　　The Toolkit provides a number of native programming containers for deploying the Toolkit's graphics in an application, both C/C++ and Java, Unix, Linux and Windows: a Motif/Gtk/Qt widget, an MFC class, Windows custom control, a Java bean and class library, an ActiveX Control and more. Click here for more information on available programming containers and deployment options.

　　A developer will only need to use a single SetResource function call or method to set any of the drawing's resources, which is a result of the resource based Programming API. The programmer needs to know only the name of a given resource, either an intuitive default such as FillColor, or any custom name given to the resource.

　　The Programming API may be used to modify resources of the drawing at run-time and supply dynamic data for real-time updates. The application needs to concern itself only with supplying new resource values, and the Toolkit's engine handles all details of the low-level graphics and damage repair. The updates are data-driven, so no CPU time is consumed if the data does not change. Click here for more information.

　　The API may also be used to handle user interaction, such as object selection or interaction with buttons, sliders and other controls. The object selection is handled transparently by the Toolkit, regardless of the screen size or zooming state, and the program's callback is invoked with all selection information every time an object of interest is selected.
