Hello,
I am developing a plugin that, for some action by the use, decorates some
projects with a special label and, on some other event, resets the
decoration. I want this to happen in the C/C++ Projects view also. I am
using the code given in the article on decorators. When the action is
taken, the labels in the navigator view get updated instantly, but the
ones in C/C++ projects view do not update. They do update in the C/C++
projects view when I restart eclipse. Here is my code ( I call the method
refreshProjectLabel() with the selected project as parameter when the
event occurs):
plugin.xml
<extension point="org.eclipse.ui.decorators">
<decorator
id="ProjectDecorator"
label="Project decorator"
state="true"
class="util.ProjectDecorator"
objectClass="org.eclipse.core.resources.IProject"
adaptable="true">
<description>
</description>
</decorator>
</extension>
class util.ProjectDecorator
package util;
import org.eclipse.core.resources.IProject;
import org.eclipse.jface.viewers.ILabelDecorator;
import org.eclipse.jface.viewers.ILabelProviderListener;
import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.jface.viewers.LabelProviderChangedEvent;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.widgets.Display;
import org.eclipse.ui.IDecoratorManager;
import org.eclipse.cdt.internal.core.model.CProject;
import projectProperties.AampBuildConfigurationPage;
import projectProperties.ConfigurationFilesPage;
public class ProjectDecorator extends LabelProvider implements
ILabelDecorator {
public ProjectDecorator() {
super();
}
// Method to decorate Image
public Image decorateImage(Image image, Object object) {
// Return null to specify no decoration
return null;
}
// Method to decorate Text
public String decorateText(String label, Object object) {
// return null to specify no decoration
IProject project = null;
if(object instanceof IProject)
project = (IProject) object;
else if(object instanceof CProject)
project = (IProject)(((CProject)object).getResource());
if(project!=null) {
try {
String selected = project.getPersistentProperty
(ConfigurationPage.lastSelectedName);
if(selected!=null)
return project.getName() + "(*)"
} catch(Exception e) {
}
}
return null;
}
public void addListener(ILabelProviderListener listener) {
super.addListener(listener);
}
public void dispose() {
}
public boolean isLabelProperty(Object element, String property) {
return false;
}
public void removeListener(ILabelProviderListener listener) {
super.removeListener(listener);
}
public static ProjectDecorator getProjectDecorator() {
IDecoratorManager manager =
cdtAampPlugin.getDefault().getWorkbench().getDecoratorManage r();
if(manager.getEnabled("aampProjectDecorator")) {
return
(ProjectDecorator)(manager.getLabelDecorator("aampProjectDecorator "));
}
return null;
}
public static void refreshProjectLabel(IProject project) {
System.out.println("Inside refresh 1");
if(getProjectDecorator()==null) {
System.out.println(" Decorator null for project "+project.getName());
return;
}
getProjectDecorator().refreshLabel(project);
}
public void refreshLabel(IProject project) {
final LabelProviderChangedEvent event = new
LabelProviderChangedEvent(getProjectDecorator(),new Object [] {project});
Display.getDefault().asyncExec(new Runnable() {
public void run() {
System.out.println(" Inside run");
fireLabelProviderChanged(event);
}
});
}

This is the same problem addressed by
https://bugs.eclipse.org/bugs/show_bug.cgi?id=36837
The c/c++ project view does not properly refresh the corresponding
ICElement in the view when the underlying IResource changes.
