## Description

A Cytoscape.js extension that wraps the [qTip jQuery library](http://qtip2.com)

**It is recommended that, where possible, you use [`cytoscape-popper`](https://github.com/cytoscape/cytoscape.js-popper) with `tippy.js` instead of `cytoscape-qtip`.**

- The [`qtip2`](https://github.com/qTip2/qTip2) library that this extension wraps is no longer maintained by its author.
- `qtip2` does not have proper support for npm+webpack and npm+browserify, whereas `cytoscape-popper` does -- as do `popper.js` and `tippy.js`.
- `cytoscape-popper` does not require `jquery`.
- `qtip2` requires the use of `jquery@1` or `jquery@2`, which are both no longer maintained.


## Dependencies

 * jQuery ^2.0 || ^1.10.0, as qTip requires it
 * qTip ^3.0 || ^2.2.0
 * Cytoscape.js ^2.2.0 || ^3.0.0


## Usage instructions

Download the library:
 * via npm: `npm install cytoscape-qtip`,
 * via bower: `bower install cytoscape-qtip`, or
 * via direct download in the repository (probably from a tag).

`require()` the library as appropriate for your project:

CommonJS:
```js
var cytoscape = require('cytoscape');
var cyqtip = require('cytoscape-qtip');

cyqtip( cytoscape ); // register extension
```

AMD:
```js
require(['cytoscape', 'cytoscape-qtip', 'jquery'], function( cytoscape, cyqtip, jquery ){
  cyqtip( cytoscape, jquery ); // register extension
});
```

Note that `jquery` must point to a jQuery object with `.qtip()` registered if AMD is used.

Plain HTML/JS has the extension registered for you automatically, because no `require()` is needed.


## API

This extension wraps the qTip API so it can be used on Cytoscape.js graph elements instead of HTML DOM elements.

You can call qTip on graph elements:
```js
eles.qtip({ /* options ... */ });
```

You can call qTip on the core:
```js
cy.qtip({ /* options ... */ });
```

See the [qTip API for details on configuration](http://qtip2.com/options).

If you want to access the qTip API for an element:
```js
var api = ele.qtip('api');
```

If you want to access the qTip API for the core:
```js
var api = cy.qtip('api');
```

See the [qTip docs for details on the API](http://qtip2.com/api).  If you create more than one qTip on an element and use its API, you'll have to cache the `api` references after creating each qTip.


## API restrictions

You may not use `options.position.target`.  If you require a different value, like `'body'` or `'mouse'`, you don't need this extenstion -- you can simply use the qTip APIs directly on a DOM element.


## API additions

These are additional options you can use for convenience.  Remember: This extension is just a wrapper to qTip.  If you require more complex behaviour, you should manually use the [qTip API](http://qtip2.com/api).

 * `options.position.adjust.cyViewport` : When `true`, updates element qTip position on zoom and pan.  Note you'll need your own mechanism to hide out-of-bounds qTips, such as customising the parent container.

 * `options.show.cyBgOnly` : When `true`, shows core qTips only for events originated on the core (not bubbled).  Useful for "background" events.

 * `options.hide.cyBgOnly` : When `true`, hides core qTips only for events originated on the core (not bubbled).  Useful for "background" events.

 * `options.hide.cyViewport` : When `true`, hides qTips when the viewport is manipulated (i.e. zoom/pan).
