WorkbenchImages介绍

[英]This class provides convenience access to many of the resources required by the workbench. The class stores some images as descriptors, and some are stored as real Images in the registry. This is a pure speed-space tradeoff. The trick for users of this class is that images obtained from the registry (using getImage()), don't require disposal since they are shared, while images obtained using getImageDescriptor() will require disposal. Consult the declareImages method to see if a given image is declared as a registry image or just as a descriptor. If you change an image from being stored as a descriptor to a registry image, or vice-versa, make sure to check all users of the image to ensure they are calling the correct getImage... method and handling disposal correctly. Images: - use getImage(key) to access cached images from the registry. - Less common images are found by calling getImageDescriptor(key) where key can be found in IWorkbenchGraphicConstants This class initializes the image registry by declaring all of the required graphics. This involves creating image descriptors describing how to create/find the image should it be needed. The image is not actually allocated until requested. Some Images are also made available to other plugins by being placed in the descriptor table of the SharedImages class. Where are the images? The images (typically png file) are found the plugins install directory How to add a new image Place the png file into the appropriate directories. Add a constant to IWorkbenchGraphicConstants following the conventions Add the declaration to this file
[中]此类提供了对工作台所需的许多资源的方便访问。该类将一些图像存储为描述符，而一些图像则作为真实图像存储在注册表中。这是一种纯粹的速度空间权衡。此类用户的诀窍是，从注册表（使用getImage（））获取的图像不需要处理，因为它们是共享的，而使用getImageDescriptor（）获取的图像则需要处理。请参阅declareImages方法，查看给定图像是声明为注册表图像还是仅声明为描述符。如果将图像从作为描述符存储更改为注册表图像，或者反之亦然，请确保检查图像的所有用户，以确保他们调用的getImage是正确的。。。方法和正确处理。图像：-使用getImage（键）从注册表访问缓存的图像。-通过调用getImageDescriptor（key）可以找到不太常见的图像，其中key可以在iWorkbenchGraphic常量中找到。此类通过声明所有必需的图形来初始化图像注册表。这涉及到创建图像描述符，描述如何创建/查找需要的图像。在请求之前，不会实际分配映像。通过将一些图像放在SharedImages类的描述符表中，其他插件也可以使用这些图像。图像在哪里？图像（通常是png文件）可以在插件安装目录中找到。如何添加新图像将png文件放入适当的目录中。向iWorkbenchGraphic常量中添加一个常量按照约定将声明添加到此文件
