Hi
I am developing an custom developer studio on the base of eclipse platform.
I need to insert piece of code into the current opend page editor(the current opend file for editing).

I fond this but i don't know how to use it. Also it may be wrong. Can anyone help?

IWorkbenchWindow window = wb.getActiveWorkbenchWindow();
IWorkbenchPage page = window.getActivePage();
IEditorPart editor = page.getActiveEditor();
IEditorInput input = editor.getEditorInput();

Thanks

It really depends on the kind of editor. But if it is the default text editor, there is API for working with it (TextEditor, ITextEditor, IDocumentProvider, IDocument).

If you mean the Java editor, that extends from the TextEditor to provide java specific APIs.

I figure it out Smile

IWorkbenchWindow window = wb.getActiveWorkbenchWindow();
IWorkbenchPage page = window.getActivePage();
IEditorPart editor = page.getActiveEditor();
if (!(editor instanceof AbstractTextEditor)) {
return;
}
IEditorInput input = editor.getEditorInput();

ITextEditor texteditor = (ITextEditor) editor;
IDocument document =
texteditor.getDocumentProvider().getDocument(input);
try {
ISelection selection =
texteditor.getSelectionProvider().getSelection();
int cursorOffset = ((ITextSelection) selection).getOffset();
// int line = ((ITextSelection) selection).getEndLine();
document.replace(cursorOffset, 0, key + "=" + keyCodes.get(key));
} catch (BadLocationException e) {
e.printStackTrace();
}
