Loading Icons From Another Plugin [message #333718]

Hi Guys,

I have been struggling with this one for a while so any help would be
appreciated.

Basically, I wish to access some of the standard JDT icons for use within
my own plugin such as field_private_obj.gif. (I wish to find the URL - not
load the ImageDescriptor)

If I copy the jdt jar which contains the icons into my own plugin
classpath I can access the icons via ......

URL theURL = FileLocator.find(MyPlugin.getDefault().getBundle(), new
Path("icons/full/obj16/field_private_obj.gif"),null);

However, its not very clean to copy the icons and I would prefer to access
the originals. The issue is I cant seem to find the appropriate JDT class
to substitute. JDIDebugPlugin does not seem to work - if indeed this is
the right route to go down.

i.e.

URL theURL = FileLocator.find(<<Some JDT Plugin
Class>>.getDefault().getBundle(), new
Path("icons/full/obj16/field_private_obj.gif"),null);

Any thoughts on which plugin class to use or if there is a completely
separate mechanism. Please note - I want to find the URL not the swt image
descriptor or load the images from an image directory.

Kind Regards,

Mathew

You can use the platform URL:
http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclips e.platform.doc.isv/reference/misc/platform-scheme-uri.html

i.e. new URL("platform:/plugin/com.myplugin/icons/me.gif");

This is already supported (although not by the tooling) in most of the
org.eclipse.ui extension points that have "icons" type attributes as
well, or any other plugins that use
org.eclipse.ui.plugin.AbstractUIPlugin.imageDescriptorFromPl ugin(String,
String)

Is it that you want to load it from the URL over simply getting a
framework supplied ImageDescriptor? Or that you aren't using SWT at
all, and need the URL and its InputStream?

Although once you have the URL you can use
ImageDescriptor.createFromURL(*) to get the image descriptor.
