The methods are for the input methods showing various information near your text. Not for general mouse event handling.
You still need to implement the mouse handling for selection with a custom code for your view.
To handle mouse events in a text input friendly way, you want to first pass all mouse events to -[NSTextInputContext handleEvent:].
If the method returned NO (meaning the text system didn't swallow the event), then, you can perform your custom mouse handling logic for that event.
