  • [EXTJSIV-608] Fix issue when creating records at a remote source
  • [EXTJSIV-450] FocusManager will only add tabIndex to DOM nodes that really need them for programmatic focusing. This will ensure default tabIndicies will remain in tact
  • [EXTJSIV-589] CellEditing now fires beforeedit, validateedit and afteredit appropriately
  • [EXTJSIV-610] CellModel will now call its base Model's doSelect and doDeselect functions so it is maintaining the selected record along with the selected position (row/column)
  • [EXTJSIV-418] CheckColumn now will handle the Enter/Space keys for toggling its select state
  • [EXTJSIV-609] CellModel fires its select/deselect events now

  • [EXTJSIV-641] Fix an issue with creating items into a local storage object
  • [EXTJSIV-440][EXTJSIV-633] Fix Ext.ux.AnimatedDataView cross-browser issue
  • CellEditing will complete an edit before grabbing critical information about the next edit, since the view is refreshed upon edit completion
  • [EXTJSIV-371] CellEditing and CellModel will continue cell editing on tabs even across cells with no editor, and stop when the editing ends via a non-tab exit point such as blurring the field
  • [EXTJSIV-606] Constrained Windows no longer lose their center positioning
  • [EXTJSIV-508] Give a visual indication of a selected/focused tree node in the check-tree example
  • [EXTJSIV-508] Tree selection model handles enter/space to check any checkbox tree nodes
  • [EXTJSIV-663] Ensure ServerProxy checks if the value is defined as opposed to just truthy
  • [EXTJSIV-593] Numeric axis is now aware of chart substores, that way it can update when grouping/ungrouping time axis

• Enhancements
  • [EXTJSIV-73] Optimized class system performance - round 1
  • Added a simple Gauge Chart
  • Add Ext.Array.sort which is a guaranteed stable sort
  • [EXTJSIV-556] Implement a buffered grid example loading thousands records and buffering the rendering. Required minor changes to PagingScroller, BufferStore and related classes
  • [EXTJSIV-193] Put iconCls and tools into ghosted windows
  • [EXTJSIV-471] RowEditing will now scroll the buttons into view when they are out of sight due to being near the bottom. Also will enforce row selection and keeping a row in view when starting an edit for smoother animations
  • [EXTJSIV-426] Remove redundant validation for allowBlank in Ext.form.Text
  • [EXTJSIV-427] Date and Time would always return null from getValue if the raw value could not be parsed as a date; this was resulting in such values being treated as valid during validation and not being seen as dirty. Changed so that getValue will return the raw value if it cannot be parsed. Also added logic to attempt parsing of the 'value' config during init so that originalValue is a valid Date object for dirty comparison
  • [EXTJSIV-448] Implement readOnly and setReadOnly for Checkbox and Radio fields
  • [EXTJSIV-416] Give fields within fieldset an anchor so they get a width in IE6
  • [EXTJSIV-530] Added port number support to localhost detection
  • Add required classes to Chart LiveUpdate example
  • Increase LiveSearchGridPanel reactiveness
  • [EXTJSIV-529] Element.getColor() will properly accept an empty string as a prefix, which is needed for color animations
  • [EXTJSIV-529] Enable afterRepair fx on dd.DragZone and TreeViewDragZone
  • [EXTJSIV-38] TreeViewDropZone will now highlight successfully dropped nodes
  • [EXTJSIV-38] Use the selectedItemCls setting on TableView prototype to handle the quick remove/add of that cls when highlighting a repair
  • [EXTJSIV-38] TreeViewDragZone will highlight all records that were dragged, for the case of multiselect tree sel model
  • [EXTJSIV-185] Removed .png slicer images + changing to gif (we <3 IE6)
  • [EXTJSIV-346] adding gif versions of icons for treegrid example
  • [EXTJSIV-475] LoadMask may now be configured with a Component to mask as an alternative to just an element. If configured with a Component, it masks the Component's contentTarget. If the Component changes size during loading, the mask's message is recentered. DataView configures its LoadMask by passing itself if it is standalone, or its owning Container if it is inside a Container
  • [EXTJSIV-478] Added the empty cls to all browsers, not just browsers that do not support `placeholder`. this is because of a styling issue in webkit
  • [EXTJSIV-540] Button over when disabled will not apply the hover background linear gradient anymore. disabled classes now get cascaded priority over background-image
  • [EXTJSIV-457] The DragZone was triggering a selection change on mousedown, which was resulting in duplicate selection calls when the DataView was configured to select on click. Moved the former from the mousedown handler to the start of the drag to avoid duplicate selection
  • Improved some Loader's alias functions for performance
  • [EXTJSIV-258][EXTJSIV-259]Refactor Shadow for floating Components
  • [EXTJSIV-551] Menu should not fire click, mouseover, or mouseleave events when its disabled. Menu items will not get any interaction when the menu is disabled
  • Menu will only activate items that can be activated, however, always deactivate the active item when applicable
  • [EXTJSIV-502] Add comment in HtmlEditor explaining how forcing documentMode in the Web Developer Tools will override the mode used by the iframe, causing scrollbars in IE8
  • [EXTJSIV-543] Horizontal scrolling does not rely on having records within the body of the grid. It is calculated off of the headercontainer instead
  • [EXTJSIV-547] Added in browser check for Opera for Mousewheel. Found additional information about Opera and its' mousewheel implementation here: http://www.switchonthecode.com/tutorials/javascript-tutorial-the-scroll-wheel To quote the important parts... "The weirdness comes in because IE and Firefox have very different names for the scroll event. In Internet Explorer, the event is called onmousewheel, while in Firefox the event is called DOMMouseScroll. To make it even worse, Opera uses the Internet Explorer event name (without the 'on' part, so just mousewheel), but Opera needs to use the Firefox way of attaching event listeners."
  • [EXTJSIV-564] Implement index support in selectRange rather than requiring the developer to pass a record instance
  • Updated grid row selection stuff to support IE better
  • [EXTJSIV-447] Add fieldStyle config and setFieldStyle method to Ext.form.BaseField, to allow direct manipulation of the inputEl CSS style
  • Legacy code in the widgets directory removed
  • RowEditor offsets itself by using bottom instead of top, in case of tall rows
  • [EXTJSIV-567] Table State implementation now restores width and visibility
  • [EXTJSIV-532] Add tooltip support on Radar series
  • [EXTJSIV-559][EXTJSIV-373]Provide accurate repair position for Header Drag Zones
  • [EXTJSIV-358] HeaderContainer will disable checkbox in column menu when there is only a single header
  • [EXTJSIV-582] Add Ext.Error custom error reporting class
  • [EXTJSIV-574] Add an alias for all series and handle custom series creation and adding them in an imperative way
  • [EXTJSIV-514] Reimplement rendering of Checkbox and Radio to use a custom image rather than native controls, for greater styling control and consistency across browsers
  • [EXTJSIV-241] Lots of cleanup on Component destroy method
  • [EXTJSIV-599] Make node loaded a field in NodeInterface. When appending a child to a node, mark it as loaded
  • Add the ability to pass a url to the load method on a Store with a ServerProxy defined on it
  • [EXTJSIV-394] Added itemTpl support for DataView
  • Add method to allow destroying the field layout's singleton QuickTip instance
  • [EXTJSIV-604] Allow height to be set on text fields
  • The footer toolbar's (fbar/buttons cfg) spacer shouldn't be focusable anymore
  • Button now has a visual state when focused, which currently mirrors the mouseover state. Also removed a focus/blur method in Button that was unnecessary
  • [EXTJSIV-450] FormPanel will provide default tab stops for its fields and buttons, so that all fields are tabbed through first, and then buttons second
  • [EXTJSIV-450] AbstractPanel and AbstractDock will return/render docked items in their visual representative order, respectively. Docked items have a default weighting, so that they are returned/rendered in (t,l,r,b) order. In the case of a Dock layout, the top/left items are rendered before any existing DOM nodes in the render target (body el, in the case of a Panel), and right/bottom items are rendered after the existing DOM nodes. This keeps our DOM nodes in order of their visual representation to support tab stops, ARIA readers, etc. Also, getDockedItems/getRefItems of AbstractPanel will return the same type of ordering by default to support logical ordering of ComponentQuery's and FocusManager navigation
  • Move FocusManager's tabIndex whitelist to the prototype so it's not defined over and over again for each call to setFocus
  • [EXTJSIV-418] Added keydown event handling to DataView
  • [EXTJSIV-600] Allow form fields to display all errors returned from getErrors at once, rather than only displaying the first
  • [EXTJSIV-304] Grid reconfigure method implemented
  • [EXTJSIV-498] Changed DataView to store the internal record IDs on the view DOM nodes for lookup by record and vice versa. This matters since blockRefresh's can happen and the store becomes out of sync with the DOM nodes, such as was the case with the Animated DataView plugin
  • [EXTJSIV-483] Implement expanded cls for rows inside collectData instead of getRowClass. This allows the user to override getRowClass without them having to worry about expanded state
  • [EXTJSIV-628] Added remove and destroy methods in Sprite.
  • [EXTJSIV-55] Add boxLabelAlign config to allow the user to place the boxLabel before or after the checkbox/radio
  • [EXTJSIV-517] Optimized buffering of requests in PagingScroller
  • [EXTJSIV-596] border:false on a Window removes borders from the body. The Window itself remains framed
  • [EXTJSIV-523] Use the verticalScrollers calculated height when available rather than the raw dom
  • [EXTJSIV-315] Updated access theme to have better styling across all components
  • [EXTJSIV-613] Move extraParams onto the object instead of being per request
  • RowEditor now transitions the error summary tip properly on back-to-back invalid records
  • Remove the inline unselectable cls, and instead call unselectable() on the table view's el after it's been rendered. This fixes a selection problem in Chrome when double clicking in a grid
  • [EXTJSIV-527] Add a workaround for the WebKit MarginRight bug with Anchor Layouts to make them much faster
  • [EXTJSIV-527] Componentlayout.afterLayout will now only be called when a ComponentLayout occurs
  • [EXTJSIV-527] Ensure Card.setActiveItem calls onLayout properly
  • Moved all locking behavior out of the LockingGridPanel subclass
  • [EXTJSIV-660] Add startDay to Date Field
  • [EXTJSIV-653] Added DirectStore shortcut
• API Changes
  • [EXTJSIV-276] The "headers" config in GridPanel has been renamed to the 3.x compatible "columns". All supporting classes are now named XxxxxColumn and are in the Ext.grid.column package. Column xtypes are the same as they were in 3.x
  • [EXTJSIV-562] Added hideEmptyLabel config which automatically collapses the label space when fieldLabel is empty. Made this the default behavior everywhere; this is a slight change from the old form layout which defaulted to maintaining the space unless hideLabel=false
  • [EXTJSIV-59] Rename some methods in Menu to be consistent with framework standards
  • Modified field layout to avoid setting styles when not needed. The fieldLabel element's styles are now applied during render in the template and not in the layout. Fields whose size are not managed by a container no longer set their internal element sizes during layout this can result in wrapping since fields are floated
  • Add inverse iteration support to Ext.Array.each
  • Rename hlColor to repairHighlightColor for Tree DragSource
  • [EXTJSIV-38] TreeViewDDPlugin now has "nodeHighlightColor" which is used on repairs and drops, if applicable. Passing it as the "repairHighlightColor" to the drag zone in this commit. Will be passed to drop zone as "dropHighlightColor"
  • [EXTJSIV-38] Renamed hlDrop to nodeHighlightOnDrop and nodeHighlightOnRepair on the TreeViewDDPlugin class. They are routed to the TreeViewDragZone and TreeViewDropZone as repairHighlight and dropHighlight respectively
  • [EXTJSIV-552] Rename MessageBoxWindow to MessageBox
  • Move all locales package from core to extjs
  • [EXTJSIV-548] Add allowDrag config option on NodeInterface. Set it to false by default for root nodes
  • [EXTJSIV-549] Change the names for the relayed events from TreeStore to TreePanel so that they don't collide with Panel's events
  • [EXTJSIV-602] Put GridViewDDPlugin and TreeViewDDPlugin into proper namespaces (Ext.grid.plugin)
  • [EXTJSIV-269] Renamed enableCacheBuster to disableCaching, added disableCachingParam config
  • [EXTJSIV-581] Fixed up the API for TreeStore, TreeView and TreePanel. Also fixed some bugs related to changing the root node dynamically, loading data after TreePanel has already been created and expanding a node while its loading
  • [EXTJSIV-598] We no longer use the global QuickTips singleton for form error tips. We now create a QuickTip singleton just for the field layout, with the proper baseCls for framing, and register it to respond to an 'errorqtip' property
  • [EXTJSIV-534] Refactor Lockable into mixin
  • AbstractSummaryFeature, ChunkingFeature, GroupingFeature, RowSummaryFeature, RowBodyFeature, RowWrapFeature, and SummaryFeature moved to the Ext.grid.feature namespace
  • Rename locked from Header/Column to ddLock so that it doesnt conflict with the new locking functionality
• Compatibility Changes
  • Removed compat reversing of El.down/El.child - There are too many places in Ext itself that use these calls, and reversing them in the compat layer to match 3.x behavior breaks some Ext 4 code. This will have to remain a documented breaking change in the migration guide
  • Set up compat code for TreePanel, AsyncTreeNode, TreeLoader and TreeSorter
