編程API

　　當(dāng)圖片創(chuàng)建程序被用于交互式繪制設(shè)計時，編程API可為程序提供一種與程序中的繪制進(jìn)行互動的方法。API是工具包中第二重要的元素。當(dāng)繪制功能內(nèi)置于一個應(yīng)用程序時，它能使您訪問在創(chuàng)建程序中創(chuàng)建的對象。

　　工具包為在應(yīng)用程序中部署工具包圖片提供了大量的本地編程存儲器，包括C/C++ 以及Java、Unix、Linux以及Windows：一個Motif/Gtk/Qt widget、一個MFC 類, Windows自定義控制、一個Java bean 以及類庫、一個ActiveX Control等。點這里以獲取更多關(guān)于編程存儲器以及部署選項的信息。

　　開發(fā)人員只需使用一個簡單的SetResource功能調(diào)用或程序就能設(shè)置任意的基于編程API資源結(jié)果的繪制資源。程序員只需知道給出資源的名稱，而不需要知道如FillColor等的直觀默認(rèn)設(shè)置或任何資源的自定義名稱。

　　編程API可用于在運行時修改繪制資源以及為實時更新提供動態(tài)數(shù)據(jù)。通過提供新的資源值，應(yīng)用程序只需注意程序本身。并且工具包引擎會處理低級別圖片與損壞修復(fù)的所有細(xì)節(jié)。更新通過數(shù)據(jù)驅(qū)動，所以如果數(shù)據(jù)不改變就不需要消耗CPU時間。

　　API同樣能用來處理用戶互動，如對象選擇或與按鍵的交互以及動態(tài)顏色滑塊與控制組件。不管屏幕尺寸大小或變焦?fàn)顟B(tài)，對象選擇通過工具包進(jìn)行透明處理。每當(dāng)選擇感興趣的對象時，會觸發(fā)具有所有選項信息的程序回調(diào)。

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.
