Hello all,

Is there a simple way of obtaining the IJavaElement associated with the
currently selected text? The only way I can accomplish this is using an
internal class, which I would like to avoid:

if (selection instanceof ITextSelection) {
ITextSelection textSelection = (ITextSelection) selection;
IWorkbenchPage activePage =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();
if (activePage != null) {
IEditorPart editor = activePage.getActiveEditor();
if (editor instanceof CompilationUnitEditor) {
CompilationUnitEditor unitEditor = (CompilationUnitEditor) editor;
IJavaElement element = (IJavaElement) unitEditor.getViewPartInput();
}
}
}

In the above code, CompilationUnitEditor is internal. Any help would be
appreciated.

Jeff

I'm not sure about which CompilationUnitEditor you're talking about but
the one I know does not have a getViewPartInput() method. Anyway, what
you should use ist:
typeRoot= org.eclipse.jdt.ui.JavaUI.getEditorInputTypeRoot(IEditorInpu t)
typeRoot.codeSelect(selectionOffset, selectionLength)

Hi Dani,

Thanks for the reply. CompilationUnitEditor is a class in the internal
package org.eclipse.jdt.internal.ui.javaeditor. I wanted to avoid using it.

The example code you gave uses JavaUI.getEditorInputTypeRoot(IEditorInput),
which is new in Eclipse 3.4. Is there a different way of accomplishing this
using Eclipse 3.3?

Thanks,

Jeff

I know that. But this one does not have a getViewPartInput() method.

org.eclipse.jdt.ui.JavaUI.getEditorInputJavaElement(IEditorI nput)

It is located in the super class (JavaEditor).
