In Eclipse RCP plug-in development, reference the picture resources packaged in the plugin directory

RCP developed with Eclipse plug-in technology, if you use relative home/absolute path access to file resources such as pictures, running in the eclipse environment is no problem, but when you lead to plug-in plugins, they all lead to a jar file, Then the code that turns out to be working correctly will go wrong.

The solution to this problem is simple, using the Imagedescriptorfromplugin method of the Org.eclipse.ui.plugin.AbstractUIPlugin class provided by Eclipse, the sample code is as follows:

String imagePath = "icons/logo.png"; //要读取的图片 文件的路径
ImageDescriptor descriptor = AbstractUIPlugin.imageDescriptorFromPlugin ("com.untworld.esystem.launcher",imagePath); //com.untworld.esystem.launcher是我的插件名称，Eclipse queries the corresponding location based on this name

This way you can access the package in the plug-in jar of the picture Resources!
