<h3>TooltipToggle</h3>
<p>
Try hovering over {tooltip}. The child passed into TooltipToggle must be a react element (i.e. can't just be a string).
</p>
<p>
A TooltipToggle has four possible placements:
<TooltipToggle container={this} content="the human">
<strong>top (default)</strong>
</TooltipToggle>,
<TooltipToggle container={this} placement="left" content="torch was">
<strong>left</strong>
</TooltipToggle>,
<TooltipToggle container={this} placement="bottom" content="denied a">
<strong>bottom</strong>
</TooltipToggle>, and
<TooltipToggle container={this} placement="right" content="bank loan">
<strong>right</strong>
</TooltipToggle>.
</p>
<p>
Remember though, that touch-screen devices can't hover (and tooltips are a terrible pattern for mobile), so use them sparingly.
</p>
<p>
Make sure the container has enough padding underneath, as the tooltip will move vertically to stay within the confines of the container.
</p>
<h3>Dropdown</h3>
<p>
Very similar to TooltipToggle, but the children prop is the content you want inside the dropdown, and you pass in a trigger to open and close the dropdown.
</p>
<div style={{ textAlign: 'center' }}>
<Dropdown
trigger={
<Btn className={m.mbs}>Toggle dropdown <Icon name="triangle"/></Btn>
}
>
Some content inside the dropdown
</Dropdown>
<br/>
<Dropdown
placement="left"
container={this}
trigger={
<Btn className={m.mbs}>Toggle left <Icon className={m.rotate90} name="triangle"/></Btn>

trigger={
<Btn className={m.mbs}>Toggle top <Icon className={m.rotate180} name="triangle"/></Btn>
}
>

<p>
All of the above components will render via a portal to the document body by default. An optional <code>container</code> can be passed in, which is a node to mount the component into.

/**
* Summary of `ReactBrowserEventEmitter` event handling:
*
* - Top-level delegation is used to trap most native browser events. This
* may only occur in the main thread and is the responsibility of
* ReactEventListener, which is injected and can therefore support pluggable
* event sources. This is the only work that occurs in the main thread.
*
* - We normalize and de-duplicate events to account for browser quirks. This
* may be done in the worker thread.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.
*

* We listen for bubbled touch events on the document object.

* `Transaction` creates a black box that is able to wrap any method such that

* creation time. The `Transaction` class itself will supply one additional
* automatic invariant for you - the invariant that any transaction instance
* should not be run while it is already being run. You would typically create a
* single instance of a `Transaction` for reuse multiple times, that potentially
* is used to wrap several different methods. Wrappers are extremely simple -
* they only require implementing two methods.

* - Flushing a queue of collected DOM mutations to the main UI thread after a
* reconciliation takes place in a worker thread.
* - Invoking any collected `componentDidUpdate` callbacks after rendering new
* content.
* - (Future use case): Wrapping particular flushes of the `ReactWorker` queue
* to preserve the `scrollTop` (an automatic scroll aware DOM).
* - (Future use case): Layout calculations before and after DOM upates.
*

* - A module that has an `initialize` method that returns any precomputation.

* Extend an event with additional view-specific methods.

* group - Returns the currently active scenegraph group (if any).
* This method accepts a single string-typed argument indicating the name

* the item up towards the root to search for a matching group. If no
* argument is provided the enclosing group for the active item is
* returned, unless the item it itself a group, in which case it is
* returned directly.
* xy - Returns a two-element array containing the x and y coordinates for
* mouse or touch events. For touch events, this is based on the first
* elements in the changedTouches array. This method accepts a single
* argument: either an item instance or mark name that should serve as
* the reference coordinate system. If no argument is provided the
* top-level view coordinate system is assumed.
* x - Returns the current x-coordinate, accepts the same arguments as xy.
* y - Returns the current y-coordinate, accepts the same arguments as xy.
* @param {Event} event - The input event to extend.
* @param {Item} item - The currently active scenegraph item (if any).

* @ngdoc overview
* @module knalli.angular-vertxbus
* @name knalli.angular-vertxbus
* @description
*
* Client side library using VertX Event Bus as an Angular Service module
*
* You have to define the module dependency, this module is named `knalli.angular-vertxbus`.
*
* <pre>
* angular.module('app', ['knalli.angular-vertxbus'])
* .controller('MyCtrl', function(vertxEventBus, vertxEventBusService) {
*
* // using the EventBus directly
* vertxEventBus.send('my.address', {data: 123}, function (reply) {
* // your reply comes here
* });
*
* // using the service
* vertxEventBusService.send('my.address', {data: 123}, {timeout: 500})
* .then(function (reply) {
* // your reply comes here
* })
* .catch(function (err) {
* // something went wrong, no connection, no login, timed out, or so
* });
* });
* </pre>
*
* The module itself provides following components:
* - {@link knalli.angular-vertxbus.vertxEventBus vertxEventBus}: a low level wrapper around `vertx.EventBus`
* - {@link knalli.angular-vertxbus.vertxEventBusService vertxEventBusService}: a high level service around the wrapper
*
* While the wrapper only provides one single instance (even on reconnects), the service supports automatically
* reconnect management, authorization and a clean promise based api.
*
* If you are looking for a low integration of `vertxbus.EventBus` as an AngularJS component, the wrapper will be your
* choice. The only difference (and requirement for the wrapper actually) is how it will manage and replace the
* underlying instance of the current `vertx.EventBus`.
*
* However, if you are looking for a simple, clean and promised based high api, the service is much better you.

* @ngdoc service
* @module knalli.angular-vertxbus
* @name knalli.angular-vertxbus.vertxEventBusService
* @description
* A service utilizing an underlying Vert.x Event Bus
*
* The advanced features of this service are:
* - broadcasting the connection changes (vertx-eventbus.system.connected, vertx-eventbus.system.disconnected) on $rootScope
* - registering all handlers again when a reconnect had been required
* - supporting a promise when using send()
* - adding aliases on (registerHandler), un (unregisterHandler) and emit (publish)
*
* Basic usage:
* <pre>
* module.controller('MyController', function('vertxEventService') {
* vertxEventService.on('my.address', function(message) {
* console.log("JSON Message received: ", message)
* });
* vertxEventService.publish('my.other.address', {type: 'foo', data: 'bar'});
* });
* </pre>
*
* Note the additional {@link knalli.angular-vertxbus.vertxEventBusServiceProvider configuration} of the module itself.

If any column is configured with a `nodeFormatter`, the `modelList` is"," iterated again to apply the `nodeFormatter`s.",""," Supported properties of the column objects include:",""," * `key` - Used to link a column to an attribute in a Model."," * `name` - Used for columns that don't relate to an attribute in the Model"," (`formatter` or `nodeFormatter` only) if the implementer wants a"," predictable name to refer to in their CSS."," * `cellTemplate` - Overrides the instance's `CELL_TEMPLATE` for cells in"," this column only."," * `formatter` - Used to customize or override the content value from the"," Model. These do not have access to the cell or row Nodes and should"," return string (HTML) content."," * `nodeFormatter` - Used to provide content for a cell as well as perform"," any custom modifications on the cell or row Node that could not be"," performed by `formatter`s. Should be used sparingly for better"," performance."," * `emptyCellValue` - String (HTML) value to use if the Model data for a"," column, or the content generated by a `formatter`, is the empty string,"," `null`, or `undefined`."," * `allowHTML` - Set to `true` if a column value, `formatter`, or"," `emptyCellValue` can contain HTML. This defaults to `false` to protect"," against XSS."," * `className` - Space delimited CSS classes to add to all `<td>`s in a"," column.",""," Column `formatter`s are passed an object (`o`) with the following"," properties:",""," * `value` - The current value of the column's associated attribute, if"," any."," * `data` - An object map of Model keys to their current values."," * `record` - The Model instance."," * `column` - The column configuration object for the current column."," * `className` - Initially empty string to allow `formatter`s to add CSS"," classes to the cell's `<td>`."," * `rowIndex` - The zero-based row number."," * `rowClass` - Initially empty string to allow `formatter`s to add CSS"," classes to the cell's containing row `<tr>`.",""," They may return a value or update `o.value` to assign specific HTML"," content. A returned value has higher precedence.",""," Column `nodeFormatter`s are passed an object (`o`) with the following"," properties:",""," * `value` - The current value of the column's associated attribute, if"," any."," * `td` - The `<td>` Node instance."," * `cell` - The `<div>` liner Node instance if present, otherwise, the"," `<td>`.
