This would be an extremely useful feature to be made available (for me, at least ;)). I'm working on a visual editor that has it's own problem marker types that are displayed in a standard java editor. Right now they look like any other java problem. It would be nice if I could provide my own images to distinguish between the two problem types.
If this were to be made API, some problems with it would need to be addressed. For example, items in the registry are currently ordered by declaring plugin id then by order of extension within that plugin, and the search for a marker image provider that matches the given marker's type is done in this order. This can make it appear not to work in some simple scenarios. For example: - plugin zzz defines marker type zzzMarker which is a subtype of core's Task marker type - plugin zzz also defines a markerImageProvider extension point that associates zzzMarker markers with an image In this scenario, the image returned will be the regular task marker image because org.eclipse.ui, which defines the markerImageProvider for Tasks, comes before zzz. I see two possible approaches: (1) find the marker image provider that most closely matches the given marker's type (i.e. fewest steps in the supertype chain) (2) introduce some other ordering criteria, e.g. markerImageProvider extension id (1) will require new core API to expose the marker type hierarchy (2) is also arbitrary, but gives the plugin developer more control since the id of the markerImageProvider need not prefixed by the containing plugin's id.
Note that the markerImageProvider extension point has moved to org.eclipse.ui.ide in 3.0.
This may have already been done. Not sure if it's exposed as API now.

Uh, I just came across this by chance... I'm not sure I understand this issue correctly, but the markerImageProviders extension point is public since 2.1: http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/extension-points/org_eclipse_ui_ide_markerImageProviders.html How well it works in practice may be another issue here, but as far as the extension point itself is concerned it seems to me that this bug can be closed.
IMarkerImageProvider is still internal
"As per http://wiki.eclipse.org/Platform_UI/Bug_Triage_Change_2009"

>IMarkerImageProvider is still internal And the extension point doc says at the bottom: "markerImageProvider is currently internal and should not be considered API. " JDT would like to use that extension point (see bug 308608). Boris, can we target this for 3.7?
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. If the bug is still relevant, please remove the "stalebug" whiteboard tag.
