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

It is located in the super class (JavaEditor).

Thanks, that did the trick.
