/**
* @class Ext.Fx
* A class to provide basic animation and visual effects support. Note: This class is automatically applied
* to the {@link Ext.Element} interface when included, so all effects calls should be performed via {@link Ext.Element}.
* Conversely, since the effects are not actually defined in {@link Ext.Element}, Ext.Fx must be
* {@link Ext#enableFx included} in order for the Element effects to work.
*
* Method Chaining
* It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
* they return the Element object itself as the method return value, it is not always possible to mix the two in a single
* method chain. The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
* Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately. For this reason,
* while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
* expected results and should be done with care. Also see {@link #callback}.
*
* Anchor Options for Motion Effects
* Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
* that will serve as either the start or end point of the animation. Following are all of the supported anchor positions:
Value Description
----- -----------------------------
tl The top left corner
t The center of the top edge
tr The top right corner
l The center of the left edge
r The center of the right edge
bl The bottom left corner
b The center of the bottom edge
br The bottom right corner
* Note: some Fx methods accept specific custom config parameters. The options shown in the Config Options
* section below are common options that can be passed to any Fx method unless otherwise noted.
*
* @cfg {Function} callback A function called when the effect is finished. Note that effects are queued internally by the
* Fx class, so a callback is not required to specify another effect -- effects can simply be chained together
* and called in sequence (see note for Method Chaining above), for example:
* el.slideIn().highlight();
*
* The callback is intended for any additional code that should run once a particular effect has completed. The Element
* being operated upon is passed as the first parameter.
*
* @cfg {Object} scope The scope of the {@link #callback} function
*
* @cfg {String} easing A valid Ext.lib.Easing value for the effect:
* - backBoth
* - backIn
* - backOut
* - bounceBoth
* - bounceIn
* - bounceOut
* - easeBoth
* - easeBothStrong
* - easeIn
* - easeInStrong
* - easeNone
* - easeOut
* - easeOutStrong
* - elasticBoth
* - elasticIn
* - elasticOut
*
*
* @cfg {String} afterCls A css class to apply after the effect
* @cfg {Number} duration The length of time (in seconds) that the effect should last
*
* @cfg {Number} endOpacity Only applicable for {@link #fadeIn} or {@link #fadeOut}, a number between
* 0 and 1 inclusive to configure the ending opacity value.
*
* @cfg {Boolean} remove Whether the Element should be removed from the DOM and destroyed after the effect finishes
* @cfg {Boolean} useDisplay Whether to use the display CSS property instead of visibility when hiding Elements (only applies to
* effects that end with the element being visually hidden, ignored otherwise)
* @cfg {String/Object/Function} afterStyle A style specification string, e.g. "width:100px", or an object
* in the form {width:"100px"}, or a function which returns such a specification that will be applied to the
* Element after the effect finishes.
* @cfg {Boolean} block Whether the effect should block other effects from queueing while it runs
* @cfg {Boolean} concurrent Whether to allow subsequently-queued effects to run at the same time as the current effect, or to ensure that they run in sequence
* @cfg {Boolean} stopFx Whether preceding effects should be stopped and removed before running current effect (only applies to non blocking effects)
