Activate find / replace for jface TextViewer eclipse worbench action

Question

I created an eclipse plugin with the TextViewer interface to display a text document, but the standard search / replace will remain grayed out.

Answer 1

I assume that you are using TextViewer in the view, not in the editor. In this case:

• Your view, which uses TextViewer, should "adapt" to org.eclipse.jface.text.IFindReplaceTarget , i.e. its getAdapter() should return the target from the viewer.
• You need to explicitly register a handler for the org.eclipse.ui.edit.findReplace command (which can be org.eclipse.ui.texteditorFindReplaceAction ). Check out the Platform Command Framework to get started.

Answer 2

I used Martia Kayarik pointers to answer this question. I have work with the following code, which, however, uses the internal string identifier from TextEditor. However, here everything goes.

• getAdapter() in the view should be implemented as follows ( viewer is an instance of TextViewer )

   public Object getAdapter(Class adapter) { if (IFindReplaceTarget.class.equals(adapter)) { if (viewer != null) { return viewer.getFindReplaceTarget(); } } return super.getAdapter(adapter); } 

• In the createPartControl() your view, add this code:

   FindReplaceAction findAction= new FindReplaceAction(ResourceBundle.getBundle("org.eclipse.ui.texteditor.ConstructedTextEditorMessages"), null, this); IHandlerService handlerService= (IHandlerService) getSite().getService(IHandlerService.class); IHandler handler= new AbstractHandler() { public Object execute(ExecutionEvent event) throws ExecutionException { if (viewer != null && viewer.getDocument() != null) findAction.run(); return null; } }; handlerService.activateHandler("org.eclipse.ui.edit.findReplace", handler); 

• XML is not required.
