Question

i am having trouble with custom quick-fixes, which i want to provide in my Eclipse plug-in, and i’m hoping for someone more experienced than me in Eclipse PDE to have some hints for me on this issue.

As i have understood, i can provide custom so-called “quick fixes” (or “resolutions”, in Eclipse inside terminology), by extending the extension point org.eclipse.ui.ide.markerResolution for a specific marker id, such as for example some default Eclipse marker, org.eclipse.core.resources.problemmarker.

This works for me for the default marker types and for custom marker types, BUT:
The QuickFixes, which my IMarkerResolutionGenerator provides, are only accessible from the “Problems”-View, not from the Editor, in which my markers show up.

What i have: I create markers in the default text editor, which causes (1) an icon with the markers tooltip message to show up on the left editor ruler at the line, which the marker is assigned to, (2) a marker on the right side of the editor, (3) some underlined characters in the editor, and (4) an entry in the “Problems”-view.

What i want: Just like in Java IDE support, i want to press Strg+1, or Context-Menu->Quick Fix, or to click at the error icon on the left-side-ruler, to see the available quick-fixes and to select one.

However: Only in the Problems-View am i able to get the Quick-Fixes, by pressing Strg+1 or from the context menu.

Is this the normal behaviour, and do i have to access another extension point, or the specific editors features, to hook my quick fixes into them? I haven’t found anything much detailed about it, except that everybody seems to be pretty happy with this only extension point that i have mentioned above. What am i missing?

For completion, here is my extension point definition:

<extension point="org.eclipse.ui.ide.markerResolution">
    <markerResolutionGenerator
        class="com.markers.test.MarkerResolutionGenerator"
        markerType="org.eclipse.core.resources.problemmarker">
    </markerResolutionGenerator>
</extension>

I have the same problem and I’m not sure, if this is the right way, but at least it works:

If you want to see your quick fixes in the source viewer you have to set an QuickAssistAssistant for it. In your class implementing SourceViewerConfiguration override getQuickAssistAssistant. You can instantiate org.eclipse.jface.text.quickassist.QuickAssistAssistant, but you have to set a QuickAssistProcessor, so implement the org.eclipse.jface.text.quickassist.IQuickAssistProcessor interface, especially computeQuickAssistProposals to return your quick fix proposals.

public IQuickAssistAssistant getQuickAssistAssistant(ISourceViewer sourceViewer) {
  IQuickAssistAssistant quickAssist = new QuickAssistAssistant();
  quickAssist.setQuickAssistProcessor(new MyQuickAssistProcessor());
  quickAssist.setInformationControlCreator(getInformationControlCreator(sourceViewer));
  return quickAssist; 
}

Also have a look at the code in the last post here, it is a bit messy, but you will get it. And look at this code here for an example implementation of ICompletionProposal, which you will have to return in your QuickAssistProcessor.
