Can I have problem marks in the Resource Navigator icons? [message #771990]

I have extended the CommonNavigator and LabelProvider and ResourceExtensionLabelProvider supplies correct icons for my editable files. I want to the file and all its parent folders decorated with error marks, when problems happen.

I have just realized that it is "Project Explorer" that normally provides the error mark decorations. Can I subclass from "Project Explorer" rather than from CommonNavigator?

I see that Project Explorer is defined in org.eclipse.ui.navigator.resources:

final class ProjectExplorer extends CommonNavigator

Subclassing the ProjectExplorer is not going to get what you want. Unfortunately, though it's possible to add problems markers to the CommonNavigator, it's not currently easy. You will need to look at the JDT code for how they do it. There is an outstanding bug on this to make it more easy.

I have discovered that NavigatorContentService.findPossibleLabelExtensions returns my custom NavigatorContentDescriptor and "Resources" whereas ProjectExplorer resources are described by "Working Set" and "Java Elements" extensions. Java Elements have the ProblemLabelDecorator.

How do I use it for my resources by default, so that if no custom label provider is found - use Java Elements?

After a while of hacking, I obtained the problem markers. In order to get them, you need

<contentExtension pattern="org.eclipse.jdt.java.ui.javaContent"/>

in the

<viewerContentBinding viewerId="your navigator id">
<includes>

Nice job, and my answer was probably not too helpful. I was thinking of it in terms of general problem markers and not the ones generated by JDT. Of course you are right.

You can even have markers in the title of you Editor!

Unfortunately, the icons disappear for text files in some environments,

But, there is only one thing that I do not understand: Why this stuff is part of JDT rather than the basic TextEditor and CommonNavigator? If default TextEditor does not show error marks in the title, might be it should not show the annotations in the margins either?
