PageLayout Class

Extends Base
Defined in: src/gallery-layout/js/PageLayout.js:9
Module: gallery-layout

Manages header (layout-hd), body (layout-bd), footer (layout-ft) stacked vertically to either fit inside the viewport (fit-to-viewport) or adjust to the size of the body content (fit-to-content).

The body content is sub-divided into modules, arranged either in rows or columns. The layout is automatically detected based on the marker classes attached to the two layers of divs inside layout-bd: either layout-module-row > layout-module or layout-module-col > layout-module

Each module has an optional header (layout-m-hd), a body (layout-m-bd), and an optional footer (layout-m-ft). You can have multiple layout-m-bd's, but only one can be visible at a time. If you change the DOM in any way that affects the height of any module header, body, or footer, or if you switch bodies, you must call elementResized() to reflow the layout. (Technically, you do not have to call elementResized() if you modify a module body in fit-to-viewport mode, but if you later decide to switch to fit-to-content, your optimization will cause trouble.)

If you want a row, column, or module to have a fixed size, add the class layout-not-managed to the layout-module-row, layout-module-column, or layout-module. Then use CSS to set the width of layout-module (for a row) or layout-module-col (for a col), or the height of layout-m-bd.

If the body content is a single module, it expands as the content expands (fit-to-content) until it would push the footer below the fold. Then it switches to fit-to-viewport so the scrollbar appears on the module instead of the entire viewport. (If you do not want this behavior in a particular case, add the class FORCE_FIT to layout-bd.)

Note that a non-zero margin-top on the top element or a non-zero margin-bottom on the bottom element inside any container will break the layout because browsers lie about the total height of the container in this case. Use padding instead of margin on elements inside headers and footers.

If you wish to display a loading message that automatically disappears after the first time the layout is calculated, add the class layout-loading to the div containing the message. (To be visible, this div must not be inside the div with class layout-bd, since that has visibility:hidden.)

Methods

_addAttrs

(
  • cfgs
  • values
  • lazy
)
private

Inherited from AttributeCore: attribute/js/AttributeCore.js:854

Implementation behind the public addAttrs method. This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

  • cfgs Object
    An object with attribute name/configuration pairs.
  • values Object
    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
  • lazy Boolean
    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

_addLazyAttr

(
  • name
  • [lazyCfg]
)
private

Inherited from AttributeCore: attribute/js/AttributeCore.js:360

Finishes initializing an attribute which has been lazily added.

Parameters:

  • name Object
    The name of the attribute
  • [lazyCfg] Object optional
    Optional config hash for the attribute. This is added for performance along the critical path, where the calling method has already obtained lazy config from state.

_addOutOfOrder

(
  • name
  • cfg
)
private

Inherited from AttributeCore: attribute/js/AttributeCore.js:527

Utility method used by get/set to add attributes encountered out of order when calling addAttrs(). For example, if: this.addAttrs({ foo: { setter: function() { // make sure this bar is available when foo is added this.get("bar"); } }, bar: { value: ... } });

Parameters:

  • name String
    attribute name
  • cfg Object
    attribute configuration

_aggregateAttrs

(
  • allAttrs
)
Object private

Inherited from BaseCore: base/js/BaseCore.js:618

A helper method, used by _initHierarchyData to aggregate attribute configuration across the instances class hierarchy. The method will protect the attribute configuration value to protect the statically defined default value in ATTRS if required (if the value is an object literal, array or the attribute configuration has cloneDefaultValue set to shallow or deep).

Parameters:

  • allAttrs Array
    An array of ATTRS definitions across classes in the hierarchy (subclass first, Base last)

Returns:

Object: The aggregate set of ATTRS definitions for the instance

    width in pixels

addAttr

(
  • name
  • config
  • lazy
)
Object chainable

Inherited from AttributeCore: attribute/js/AttributeCore.js:157

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>
The initial value to set on the attribute
valueFn <Function | String>

A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.

valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.

readOnly <boolean>
Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.
writeOnce <boolean> or <string>
Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)

setter <Function | String>

The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.

setter can also be set to a string, representing the name of the instance method to be used as the setter function.

getter <Function | String>

The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.

getter can also be set to a string, representing the name of the instance method to be used as the getter function.

validator <Function | String>

The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.

validator can also be set to a string, representing the name of the instance method to be used as the validator function.

lazyAdd <boolean>
Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

  • name String
    The name of the attribute.
  • config Object
    An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

    NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.

  • lazy Boolean
    (optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object: A reference to the host object.

addAttrs

(
  • cfgs
  • values
  • lazy
)
Object chainable

Inherited from AttributeCore: attribute/js/AttributeCore.js:823

Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

Parameters:

  • cfgs Object
    An object with attribute name/configuration pairs.
  • values Object
    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
  • lazy Boolean
    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

Returns:

Object: A reference to the host object.

addTarget

(
  • o
)
chainable

Inherited from EventTarget: event-custom/js/event-facade.js:496

    The name of the event
  • fn Function
    The callback to execute in response to the event
  • [context] Object optional
    Override this object in callback

    Either the handle to the subscriber or the type of event. If the type is not specified, it will attempt to remove the listener from all hosted events.
  • fn Function
    The subscribed function to unsubscribe, if not supplied, all subscribers will be removed.
  • context Object
    The custom object passed to subscribe. This is optional, but if supplied will be used to disambiguate multiple listeners that are the same (e.g., you subscribe many object using a function that lives on the prototype)

Returns:

EventTarget: the host

detachAll

(
  • type
)

Inherited from EventTarget: event-custom/js/event-target.js:479

Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.

Parameters:

  • type String
    The type, or name of the event

elementResized

(
  • el
)
Boolean

Defined in src/gallery-layout/js/PageLayout.js:1156

Call this when something changes size, to request a reflow of the layout.

Parameters:

  • el String | Node

    element that changed size

Returns:

Boolean:

true if the element is inside the managed containers

expandModule

(
  • node
)

Defined in src/gallery-layout/js/PageLayout.js:1080

Expand the specified module.

Parameters:

  • node String | Node

    .layout-module

fire

(
  • type
  • arguments
)
Boolean

Inherited from EventTarget: event-custom/js/event-target.js:673

Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters. The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object. If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.

Parameters:

  • type String | Object
    The type of the event, or an object that contains a 'type' property.
  • arguments Object
    an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

Returns:

Boolean: True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

The properties which can be modified through this interface are limited to the following subset of attributes, which can be safely modified after a value has already been set on the attribute:

readOnly;
writeOnce;
broadcast; and
getter.

Note: New attributes cannot be added using this interface. New attributes must be added using {{#crossLink "AttributeCore/addAttr:method"}}addAttr{{/crossLink}}, or an appropriate manner for a class which utilises Attributes (e.g. the {{#crossLink "Base/ATTRS:property"}}ATTRS{{/crossLink}} property in {{#crossLink "Base"}}Base{{/crossLink}}).

EventHandle

Inherited from EventTarget: event-custom/js/event-target.js:188

Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object. this.on("change", this._onChange, this); Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() after the event name. To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback. this.on({ "attrChange" : this._onAttrChange, "change" : this._onChange }); You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback. this.on([ "change", "attrChange" ], this._onChange); Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. However, it is recommended to use the event methods whenever possible.

Parameters:

  • type String
    The name of the event
  • fn Function
    The callback to execute in response to the event
  • [context] Object optional
    Override this object in callback
