How does one get an Editor instance for use in the plugin.
已回答
The following code was working , yes one of those :). The entire file is here: https://gist.github.com/digitalrinaldo/be9418b1769bb8b87d64e123a808e02f
@Override
public void update(@NotNull final com.intellij.openapi.actionSystem.AnActionEvent e) {
// Get required data keys
final Project project = e.getProject();
final Editor editor = e.getData(com.intellij.openapi.actionSystem.CommonDataKeys.EDITOR);
System.out.println ( "editor:" + editor );
//Set visibility only in case of existing project and editor
e.getPresentation().setEnabledAndVisible(project != null && editor != null);
editorMouseListener = new LocalEditorMouseListener();
editor.addEditorMouseMotionListener(editorMouseMotionListener);
final CaretModel caretModel = editor.getCaretModel();
caretModel.addCaretListener(caretListener);
}
}
Is this the correct way to get the editor instance? I am getting a null.
final Editor editor = e.getData(com.intellij.openapi.actionSystem.CommonDataKeys.EDITOR);
System.out.println ( "editor:" + editor );
The provided plugin code has a few deprecations.
This is the log for startup, Is this expected all the warnings.

Also why is the above bold text missing "a"?

Rinaldo,
Getting the Editor from the event using getData will work if you've invoked such an event in the proper context.
You can access the current Editor (s) with:
Regarding the missing "a" - warnings above are cut on the left as well - it's just a matter of the available space, presentation - don't worry about that.
What does it mean to invoke the event in the "proper context"?
When I look at https://plugins.jetbrains.com/docs/intellij/basic-action-system.html#determining-the-action-context it states that this sort of data should be available in `onUpdate`? I'm defining an `AnAction` in a custom editor and I need the instance of the editor back so that I don't need to keep state in the `AnAction`.
