	import React from 'react';
	import { editor } from 'monaco-editor';
	import IMouseTarget = editor.IMouseTarget;
	import IStandaloneCodeEditor = editor.IStandaloneCodeEditor;
	import IContentWidget = editor.IContentWidget;

	const { ContentWidgetPositionPreference } = editor;

	export type TDropHandler = (e: React.DragEvent, target: IMouseTarget, instance: IStandaloneCodeEditor) => void;
	export type TInstanceGetter = () => IStandaloneCodeEditor;
