Implemented state support as a mixin


Added html to each tab in the history example to make it clearer which tab is currently activated

FiltersFeature, a Ext.grid.Feature subclass, and ported it to work with

match

grid filter, even if it is an already instantiated Filter rather than a
filter config object

The Ext 3.x class ActionColumn has been implemented in 4.x as ActionHeader


Cleaned all locale packages files


Introduced a new getAssociatedData method on Model to make it easier to aggregate model data

Cleanup FocusManager's handling of component add/destroy when enabled


Convert TabBar to use FocusManager.subscribe instead of its own KeyNav


Grid Header needs to give visual
indication when it is focused, which will show the menu trigger. This
supports key navigation on grid headers and the ability to press down to
open the header menu. The menu needs the trigger to be shown since it
aligns itself to the trigger

text field value if it does not match the display value from the last
list selection or setValue call. Allows submitting values that do not
appear in the store


Enhance the appendChild, removeChild,
insertBefore code on the NodeInterface with suppressEvents capabilities.
This optimizes the performance of the initial Tree rendering
drastically


Implemented Grid RowEditing


Basic.updateRecord() will now use the
actual field data for updating the Model fields rather than the
submit-friendly string equivalent of the form field data. Certain string
encodings are not compatible with Model field covert methods if they
are not in the exact/proper format, e.g. Date fields


Remove Canvas support as it is not ready for release. SVG/VML still covers all desktop platforms.


API Changes


Moved methods slated for deprecation to the compat layer


Added a new ElementLoader class that is
the superclass of ComponentLoader. The purpose of this class is to
replace Ext.Updater. Updater is removed and the load method now points
to the new loader


Move model creation into the model itself, essentially deprecates regModel


Time axis now works with Dates and not formatted strings


Move Ext.util.Date methods over to Ext.Date. Changed all references to Ext.Date in code, examples and tests


Add workaround to
Ext.core.Element#getWidth to avoid Gecko bug where it returns an
offsetWidth that rounds down the actual width due to subpixel font rendering
. This logic was previously in a couple of components, this commit moves that up to Element.getWidth


Fix AbstractPanel.bodyCls to also support array values


Created an AbstractMixedCollection which MixedCollection extends from


Sortable refactored as a mixin


Refactored Sorting on MixedCollection, TreeStore, and TreePanel to use the new Sortable mixin


Absolute Layout will now always use setItemSize even if an anchor property isn't specified


Ensure the page parameter gets sent on remote data loading


Remove any trace of applyTo throughout the framework

Moved grid/CellSelectionModel.js to selection/CellModel.js,
grid/RowSelectionModel.js to selection/RowModel.js, and
grid/CheckBoxSelectionModel to selection/CheckBoxModel.js. Namespace
moved to Ext.selection as well


Set AjaxProxy as the default proxy


Normalize store aliases to be
store.name. Added the ability to specify a store configuration when
creating a data bound class. Note that this requires all of the stores
to be looked up using StoreMgr.lookup so that we can determine whether
we have received an id, a config or an instance


Enhance DataView UI event handling


Remove dependency of CellEditing on CellSelectionModel


Compatibility Changes


Implemented compat layer for PagingToolbar and MemoryProxy


Significant update to AbstractStore compat layer to handle different store/proxy/reader config setups
