And an SPI that provides the icons for X. In the LSP client you'd implement the same. Any such API/SPI could use the existing URLs (file locations) as a backup ID to aid transition. So both needs would benefit from migrating to a logical ID, as well as being able to query that ID, without any icon being loaded. Yes, something like this would be exactly what I'd have in mind for this. > that would require to change UIManager.getIcon|Image to "something different" that would involve that loading SPI (an implementation could do UIManager.get* and return the image/icon with 'logical ID' ) - the change would need to be done throughout the codebase, right ? I think the existing APIs could be just fine initially. Just keep loading icons by URL; after all, there needs to be a default icon file in the NetBeans codebase for each logical icon ID in any case. But there could indeed be an SPI that ImageUtilities will check to see if a given URL should be resolved to a different Icon instance. > Good; and what should we do with Swing calling UIManager.get() from its own code ? For this, just modify the icon in UIDefaults, like Swing intended. We already do this e.g. from Windows8LFCustoms. -- This is an automated message from the Apache Git Service.
