Weekly build notes listings

Question

Since there are major changes going on in the TLF weekly builds, and the ASDocs aren't up to date, and the changes made are not searchable, I thought people might want the list dumped on here so changes to particular classes would show up in a forum search.  To see the changes made in Build 360, check out the TLF Blog post on it ( http://blogs.adobe.com/tlf/2009/02/tlf_api_changes_in_build_370_1.html ).
Here's the list.  Maybe this could become a common practice.
Build 432, Fri May 15 2009
Changes in build 437 (2009/05/22)
    * remove flashx.textLayout.edit.UndoManager and flashx.textLayout.IUndoManager

    * Fix 2315119 - Graphic will be redrawn when link applied.
Changes in build 434 (2009/05/22)
    * Fix 2323921: RichText truncation doesn't work in all cases
Build 432, Fri May 15 2009
Changes in build 432 (2009/05/14)
    * Fixed regression that broke truncation feature
    * Added TextLineFactoryBase.isTruncated
    * Changed text line factory behavior such that scrolling is turned off when truncation options are set
Build 427, Fri May 8 2009
Changes in build 427 (2009/05/07)
    * Fix bug - RTE in computeSelectinIndexInContainer
    * Namespace change -- mxml namespace for TLF was "library:adobe/flashx/textLayout". Now it is: library://ns.adobe.com/flashx/textLayout".

Changes in build 426 (2009/05/06)
    * Fix bug - TextFlow double-deletes text when pressing the backspace or delete key
Build 422, Fri May 1 2009
Changes in build 422 (2009/04/30)
    * API Changes: TextContainerManager now has a getContentBounds function, in place of individual getters for contentLeft, contentTop, etc. ContainerController also now has a getContentBounds function, in place of individual getters. Added functions to TextContainerManager to support custom classes for ISelectionManager and IEditManager (see createSelectionManager and createEditManager).
    * API changes for TextContainerManager:
          o getInteractionManager renamed to beginInteraction(), and added a new function endInteraction() which clients should use after beginInteraction() to signal that they are done with selecting/editing. This tells the TextContainerManager that it can go back to factory mode, which is more efficient.
          o invalidateInteractionManager() removed and replaced with two new functions, invalidateSelectionFormats() which clients should called when SelectionFormats have changed, and invalidateUndoManager which clients should call to change the undo manager.
    * API Changes for InputManager
          o InputManager renamed as TextContainerManager
          o IInputManagerClient removed, now you can subclass InputManager and override its methods
    * API Changes:
          o InputManager
                + damaged property renamed to isDamaged() function
                + focusSelectionFormat renamed to focusedSelectionFormat
                + container retyped to Sprite
                + compositionWidth and compositionHeight removed as constructor parameters, now you need to set the properties on the InputManager you create
          o ContainerController
                + container retyped to Sprite
          o ISelectionManager
                + focusSelectionFormat renamed to focusedSelectionFormat
          o IConfiguration & Configuration
                + focusSelectionFormat renamed to focusedSelectionFormat
    * API Changes:
          o ISelectionManager
                + setSelection deselects if negative numbers are passed in.
                + selectAll removed, you can call ISelection.setSelection() to get the same behavior, if you need to redraw the selection, call ISelectionManager.textFlow.flowComposer.updateAllControllers().
                + flushPendingEvents moved to IInteractionHandler
                + notifyInsertOrDelete moved to IInteractionHandler
          o IUndoManager
                + clear renamed to clearAll().
                + undoLastOperation renamed to undo()
                + redoLastOperation renamed to redo()
    * API Change: SelectionEvent now contains a SelectionState, not an ElementRange; this is much cheaper for us to provide. ElementRange is now tlf_internal. ElementRange.firstLeafPosition renamed to absoluteStart, ElementRange.lastLeafPosition renamed to absoluteEnd.
    * API Change: TextScrap.copyTextScrap renamed to clone.
    * API Changes to InputManager. defaultInputManagerConfiguration renamed to defaultConfiguration. composeToController renamed to compose(), and updateToController renamed to updateContainer().
    * API Changes:
          o ISelectionManager:
                + Event handling functions moved out of ISelectionManager into new interface, IInteractionHandler
                + selectionFormat renamed to currentSelectionFormat
                + selectionState renamed to function getSelectionState()
                + setSelection now takes default parameters to select the entire flow
                + noFocusSelectionFormat renamed to unfocusedSelectionFormat
          o SelectionFormat:
                + blockAlpha reanmed to rangeAlpha
                + blockBlendMode renamed to rangeBlendMode
                + blockColor renamed to rangeColor
          o IEditManager:
                + added get undoManager()
                + added changeElementID()
                + added changeElementStyleName()
          o SelectionManager:
                + activeMark and anchorMark are now private
                + selectionChanged is private
                + setSelectionState is tlf_internal
          o EditManager:
                + stage is private
                + ChangeElementIdOperation renamed to ChangeElementIDOperation
Changes in build 420 (2009/04/28)
    * API change: Removed the misleadingly named and superfluous TextFlowLine.textIndent. Documented and ensured consistent use of TextFlowLine.lineOffset as lhe line's offset in pixels from the appropriate container inset (as dictated by paragraph direction and container block progression), prior to alignment of lines in the paragraph.
    * API change: more changes to the factory classes. ITextLineCreator is now a property of the base class, so instead of passing it in the constructor you construct and then set the property in the factory. bounds property renamed to compositionBounds, and measuredBounds renamed to contentBounds. containerController property is now private.
    * API Change: moved ITextLineCreator interface from the elements package to the compose package.
    * PlainTextExporter is now public and has methods for controlling the paragraphSeparator and whether discretionary hyphens are included in the export. To use it, you can either construct it directly, or via the TextFilter class. Removed the newlineIndicator string from IConfiguration.
    * Fixed a bug where tabs in RTL text were being being offset by textIndent and marginRight values.
Changes in build 419 (2009/04/24)
    * Once a mouseWheel event has been handled, mark with preventDefault so client applications don't also try to handle it.
    * Don't start compose if text is already composed. Optimization for callers of composeToPosition.
    * Always call resetContentTopLeft, to give more accurate top left positions, particularly for cases where the text is outdented and left aligned.
    * API CHANGE: TextLineFactory revised. It is now split into 3 classes, TextLineFactoryBase, StringTextLineFactory, and TextFlowTextLineFactory. Use StringTextLineFactory for creating TextLines from a String. Use TextFlowTextLineFactory for creating TextLines from a TextFlow. Static methods have been removed, so create a new factory in order to create lines. One factory may be reused many times, just resetting the values (text, bounds, truncation options, etc.) in between. See StaticHelloWorld.as for a simple example of how this works for Strings, see StaticTextFlow.as for a simple example of it with TextFlows.
Build 418, Fri Apr 24 2009
Changes in build 418 (2009/04/23)
    * API CHANGE: TextLineFactory revised. It is now split into 3 classes, TextLineFactoryBase, StringTextLineFactory, and TextFlowTextLineFactory. Use StringTextLineFactory for creating TextLines from a String. Use TextFlowTextLineFactory for creating TextLines from a TextFlow. Static methods have been removed, so create a new factory in order to create lines. One factory may be reused many times, just resetting the values (text, bounds, truncation options, etc.) in between. See StaticHelloWorld.as for a simple example of how this works for Strings, see StaticTextFlow.as for a simple example of it with TextFlows.
Changes in build 417 (2009/04/22)
    * Fixed Vertical Justification behavior; it now increases the spacing between consecutive lines proportionally rather than spacing lines uniformly.
    * API Changes: Renamed DisplayObjectContainerController to ContainerController, and removed IContainerController and IInternalContainerController. Wherever you used to use "IContainerController" or "DisplayObjectContainerController" now just use "ContainerController".
          o Moved some functions that were public into the tlf_internal namespace: effectivePaddingLeft, effectivePaddingTop, effectivePaddingRight, and effectivePaddingBottom.
          o ColumnState.createColumnState removed. A ColumnState constructor now takes all the relevant values, so whereever you used to do this:
                + var columnState:ColumnState = ColumnState.createColumnState(...your values here...);
          o you can now do this:
                + var columnState:ColumnState = new ColumnState();
          o ColumnState.getColumnAtIndex(index) has been renamed to getColumnAt(index). So, once you have the columnState, you do, for instance:
                + var columnRect:Rectangle = getColumnAt(0);
    * Fixed bug where spaces at end of a line would "overflow" into neighboring columns. New code keeps drawing of cursor at the column boundary and limits block selection drawing to the same bounds.
    * Enhancement to cursor navigation for Right to Left text systems. Previous code moved cursor according to logical order vs. visual order. Result was that a right arrow key press in Arabic, Hebrew or other RTL languages meant that the cursor actually moved left. New code moves cursor according to the visual order of the text based on the direction of the entire text flow. Note that changing the direction on a paragraph will not alter the behavior of the cursor, nor will the presence of LTR text within a RTL text flow. This means that if a TextFlow is set to Right to Left and a given paragraph is entirely in English and the paragraph is set to be Left to Right, the cursor will seem to move in the wrong direction. TLF does not support customization of cursor movement based on the locale or direction of anything except the parent TextFlow.
    * Fixed a bug that caused undoing an ApplyFormatToElementOperation to have no effect.
    * API Changes:
          o DisplayObjectContainer event handling functions renamed:
                + processMouseOverEvent -> mouseOverHandler
                + processMouseOutEvent -> mouseOutHandler
                + processMouseWheelEvent -> mouseWheelHandler
                + processMouseDownEvent -> mouseDownHandler
                + processMouseUpEvent -> mouseUpHandler
                + processMouseMoveEvent -> mouseMoveHandler
                + processMouseDoubleClickEvent -> mouseDoubleClickHandler
                + processFocusInEvent -> focusInHandler
                + processFocusOutEvent -> focusOutHandler
                + processActivateEvent -> activateHandler
                + processDeactivateEvent -> deactivateHandler
                + processKeyDownEvent -> keyDownHandler
                + processKeyUpEvent -> keyUpHandler
                + processTextInputEvent -> textInputHandler
                + processContextMenuSelectHandler -> menuSelectHandler
                + eventHandler -> editHandler
          o ISelectManager & SelectionManager & EditManager renamings:
                + eventHandler -> editHandler
    * API Changes: renamed IContainerController.scrollLines to getScrollDelta, renamed InputManager.scrollLines to getScrollDelta, and removed constants for default container width and height.
Changes in build 412 (2009/04/10)
    * API CHANGE: DisplayObjectContainerController methods processCopyEvent, processCutEvent, processPasteEvent, processSelectAllEvent collapsed into a single processEvent that handles all these basic events. Added to ISelectionManager a new function, processEvent for handling these same events in the SelectionManager, and removed processSelectAll, which is no longer used. cutTextScrap and pasteTextScrap moved from ISelectionManager to IEditManager, since these are editing operations.
Build 411, Fri Apr 10 2009
Changes in build 411 (2009/04/09)
    * Fixed a bug where noFocus selection format was not being set on re-activation
    * API CHANGES. These functions in IFlowComposer were renamed:
          o updateContainer -> updateToController
          o updateAllContainers -> updateControllers
          o composeContainer -> composeToController
          o composePosition -> composeToPosition
    * API CHANGE: Changing name of TextFlow.hostTextLayoutFormat to hostFormat
Changes in build 410 (2009/04/08)
    * Fix bug where leading info used for composing the next line was being saved prematurely, causing incorrect layout if the current line needed to be composed in multiple passes.
Build 409, Tue Apr 7 2009
Changes in build 409 (2009/04/07)
    * Fix bug where clicking on container when height or width NaN doesn't work. When measuring, transparent hit detect region wasn't being redrawn to correct size after composition.
    * API CHANGE: Plain-text import/export changes. Newline indicators exported based on setting in IConfiguration.newLineIndicator. On import, LF/CR/CR+LF are all recognized as new line indicators.
    * Compose to container size with scrolling on -- previously was composing to double composer size. This may flush out some invalid line bugs.
    * Fixed a bug with blockProgression="rl" and compositionWidth=NaN, lines were getting improperly clipped out so that no text appeared.
    * API CHANGE: Renaming functions in IFormatResolver. invalidateAllTargets is now invalidateAll, and invalidateTarget is now invalidate. resolveTextLayoutFormat is now resolveFormat.
    * API CHANGE: eventMirror on FlowLeafElement and SubParagraphGroupElement is now tlf_internal.
    * API CHANGE: Moving TextRange from the edit package to the elements package.
Changes in build 406 (2009/04/02)
    * API CHANGE: Renaming DamageEvent.damageStart to damageAbsoluteStart.
    * API Change: IConfiguration.includePartialLine renamed to overflowPolicy. Defined new class OverflowPolicy that describes the different policies that can be used to control whether lines that fall at the end of the container are included in the container, or not.
Changes in build 405 (2009/04/01)
    * API CHANGE: IFlowComposer.firstDamagePosition renamed to damageStartPosition.
    * API CHANGE: Rename GeometryUtil.getRangeBounds to GeometryUtil.getHighlightBounds.
    * API CHANGE: ParagraphElement.getText now takes an additional optional parameter that specifies the terminator for the paragraph. By default, this is the Unicode paragraph terminator character (\u2029), but you can make it whatever you want, including a simple newline by passing a String for the paragraphTerminator. This change is backwards compatible for current callers of getText().
    * Fix clipping problem when text is placed above the container (6 lines aligned verticalAlign = bottom in a space that fits 4 lines).
Changes in build 404 (2009/03/31)
    * Updating typgraphic case --Markup and API Change-- Now uses a new class TLFTypographicCase, and has different options. Support for "title" and "caps" dropped. Use TLFTypographicCase with TLF in preference to flash.text.engine.TypographicCase. "smallCaps" renamed to "capsToSmallCaps". "capsAndSmallCaps" renamed to "lowercaseToSmallCaps". Also made AUTO the default setting for kerning, which matches FXG spec.
Changes in build 403 (2009/03/30)
    * format Markup Changes:
          o <TextLayoutFormat> now <format>
          o When referring to a format id, don't use brackets. So this:
            <TextLayoutFormat id="english" locale="en" fontFamily="Minion Pro"/>
            <p marginBottom="15" ><span format="{english}">This text is supposed to be in Minion Pro via a named character attribute</span></p>
            Is now this:
            <format id="english" locale="en" fontFamily="Minion Pro"/>
            <p marginBottom="15" ><span format="english">This text is supposed to be in Minion Pro via a named character attribute</span></p>
    * API Changes:
          o Rename FlowElement.textLayoutFormat -> format
          o Rename FlowElement.computedTextLayoutFormat -> computedFormat
          o Rename IContainerController.textLayoutFormat -> format
          o Rename IContainerController.textLayoutFormat -> computedFormat
          o Rename DisplayObjectContainerController.textLayoutFormat -> format
          o Rename DisplayObjectContainerController.textLayoutFormat -> computedFormat
Changes in build 402 (2009/03/27)
    * verticalAlign of "middle" or "bottom" will now align to the compositionHeight (or compositionWidth in vertical text) even if the height of the text exceeds the compositionHeight. This means that lines that don't fit may be get pushed above the box, or (for middle) pushed both above and below. It also means that all lines will forced to compose to the end, so it will be quite slow to use verticalAlign in large text flows. Made some corresponding fixes to scrolling to make it work with text off the start of the container. Added some new test cases to exercise this functionality in all the different alignment settings.
    * Scrolling fixes for next/previous line with arrow keys. Fix a bug where the arrow key would move to the end of the line if the line required composition (e.g., the line was not previously in view). Also fixed a bug when scrolling up by a line where it would scroll down instead.
    * doOperation used to return an SelectionState, but with the exception of two places that were using it internally, all external callers only checked to see if it was null or not. null was being used to indicate failure, or nothing changed, which means that the operation is not placed on the undo stack. Now it returns a Boolean, true for success, false for failure. There may be further changes in this area to make FlowOperations simpler.
Changes in build 397 (2009/03/20)
    * Made DisplayObjectContainerController's and FlowElement's TextLayoutFormat properties read/write (used to be write-only).
    * Merge ContainerControllerBase class into DisplayObjectContainerController.
    * Mark TextFlow class as final
Changes in build 396 (2009/03/19)
    * Fix RTE in StandardFlowComposer.releaseLines
    * Fix possible source of the RTE on null reference from findFirstAndLastVisibleLines in ContainerControllerBase.
Changes in build 394 (2009/03/17)
    * Fix issue with changes made in StatusChangeEvent to embedded graphics by blocking recursive composition. Bug 2298043
    * Add IFlowComposer.composeInProcess property.
    * Fixed problem where first part of a link could not be replaced by a new link. New code allows partial replacement of a link element with a selection which starts at the first character.
    * Fixed a problem where the cursor was getting set to the I-beam, and wouldn't set back.
Changes in build 393 (2009/03/16)
    * Fix a bug where keyboard navigation with linked containers was causing a scroll because it was trying to scroll to a position not in the container.
Changes in build 392 (2009/03/13)
    * Removed optimization that was preventing scrolling in the logical width direction if scrolling in the logical vertical direction was turned off.
    * Removed the container-level mouseMove and rollOver handlers which were changing the link state. These are now part of the LinkElement, and added only when they are needed.
Changes in build 390 (2009/03/11)
    * Fix for application of attributes to a point selection where only the last attribute would be applied. New code applies all attributes applied to the point.
    * IContainerController.contentWidth (or contentHeight in vertical text) is now based on the actual text width, not the unjustified text width. This fixes some problems where scrolling wasn't working correctly because the reported width of the text was greater than the compositionWidth, but lines were wrapped. It does mean that to get the unjustified width you will have to set the textAlign to something other than "justify", recompose, and then get the resulting width.
    * Fix for unintended scroll when at the end of a TextFlow.
    * Fix for RTE when dragging over text generated from a factory, or non-TLF TextLines.
    * Changes for alignment and measurement. You can now set NaN for compositionWidth or compositionHeight, and TLF will compose and use the generated contentWidth or contentHeight for alignment, scrolling, etc. The composer now generates a topLeft for the bounds, so you can make a full "content bounds" using contentLeft, contentTop, contentWidth, and contentHeight.Note that this is logical bounds and not inked bounds, so there are some circumstances where ink will not fit in the content bounds.Fixed bugs in how the factory was doing vertical alignment that caused it to be a few pixels off.Fixed some incosistencies between how the standard flow composer worked and how the factory's simple composer works -- composition results should now be more uniform. Added a new test program, MeasurementGrid, for testing all this. It's still a work in progress.
Changes in build 388 (2009/03/09)
    * Fixed issue where applying link or TCY to the last span of a paragraph caused a dangling span to remain with the para terminator.
    * Fixed issue where text would go into a link when it was the last element in a paragraph. Newly typed text now goes into a new span when the selection marker is at the last index.
Changes in build 386 (2009/03/06)
    * Fixed issue with placement of underline and strikethrough on inline images.
    * Fixed placement of underline and strikethrough on text which has a baseline shift applied to it.
Changes in build 385 (2009/03/04)
    * Combined SWC 'textLayout.swc' now included in the libs directory of the build. This includes everything from textLayout_core, textLayout_edit, and textLayout_conversion.
    * Combined RSLs now included in the rsl directory of the build. Both an unsigned SWF and signed SWZ are created. These include everything from textLayout_core, textLayout_edit, and textLayout_conversion.
Changes in build 382 (2009/03/02)
    * Fix issue with composing a TextFlow containing just an empty ParagraphElement.
    * TextLineFactory will generate lines that included InlineGraphics whose source is a "class" - normally an embedded graphic.
    * Expose eventMirrors - use FlowElement.getEventMirror function to access the eventMirror.
Changes in build 381 (2009/02/27)
    * Fixed issue with graphic assigned to ILG getting the wrong sizing.
    * Factory instance functions renamed to textLinesFromString and textLinesFromTextFlow. Static functions renamin unchanged.
Changes in build 380 (2009/02/26)
    * Made backgroundColor work with TextLineFactory. This required an API change - the callback to the factory now must take a DisplayObject as its parameter, since it won't always be passed TextLines. Also, the background shapes themselves no longer include leading, so they do not exactly coincide with the selection bounds. This was another change to support calculating the shapes during composition as opposed to afterward. Also added a snapshot test as part of FactoryImportTest that uses backgroundColor, in addition to updating the existing unit tests.
Changes in build 379 (2009/02/25)
    * Fixed for multiple containers ( we were getting incorrect textLength in the containers), as well as a fix that forces scrollToPosition to compose if the text isn't composed yet.
    * Fix so that we scroll to the active position of the selection after we extend the selection with a keyboard event. Also fixed some of the TextRangeUtil functions used for nextLine, etc. to make sure text is composed through selection before processing that depends on composition results.
    * Plain text import now consistently converts \r to space; previously it was converting only the first one. Still not clear what correct behavior should be.
Changes in build 377 (2009/02/23)
    * Fix bug with importing trailing empty div elements.
Changes in build 374 (2009/02/18)
    * Added support for TextField-style leading. A new leading model value allows lineHeight to be interpreted as the distance of line's ascent from the previous line's descent. Further, lineHeight can be negative. which specifies the criteria for truncation, the string used to indicate truncation and the format for this string.
Changes in build 372 (2009/02/16)
    * Added "enableAccessibility" property to IConfiguration, defaults to false. Allows clients to avoid paying price for TextAccImpl objects unless needed.
    * Added support for truncation for text composed using TextLineFactory. The TextLineFactory methods now take a truncation options parameter, which specifies the criteria for truncation, the string used to indicate truncation and the format for this string.
Changes in build 371 (2009/02/13)
    * Fixed a number of bugs relating to scrolling by line.
    * Measurement changes. Changed the way contentHeight and contentWidth are calculated, now they reflect the size of the text, regardless of alignment. Eliminated unjustifiedContentHeight and unjustifiedContentWidth; use contentHeight and contentWidth instead.
    * Fix RTE in damage when we try to damage back one line, for textFlow that doesn't have any leaf nodes.
    * Changed InlineGraphicElement so that GraphicElements (and the TextBlocks they are part of) don't get released. Fixes RTE on null pointer in places where we access the GraphicElement.
    * Fix bug deleting all of the last Span of a paragraph, plus some of the following paragraph.
Changes in build 370 (2009/02/12)
    * Removed textFlow property from CompositionCompletionEvent. Use event.target to get to the TextFlow.
Changes in build 369 (2009/02/11)
    * Fix issues in usage of hostTextLayoutFormat
    * Fix FXG export to not export styles with value "inherit"
    * lineBreak property no longer inherits by default
Changes in build 368 (2009/02/10)
    * Fix for RTE that happens after cancelling an operation (calling preventDefault on a FlowOperationEvent).
Changes in build 367 (2009/02/09)
    * ported to Flex 4.0.0.4836. All SWCs now build with this SDK.
Changes in build 366 (2009/02/06)
    * FlowGroupElement addChild, addChildAt and replaceChildren methods now automatically delete new elements from any existing parents. Previously the code would test for parent on new elements and throw.
    * mxmlChildren FlowElement property which is normally used for mxml compilation of TextFlow objects now always deletes existing children
    * Fix a memory leak issue with the TextLayoutFormat cache
    * Fix cascade bug with non-inheriting attributes getting inherited
Changes in build 365 (2009/02/05)
    * Changed TextLayoutFormat.backgroundColor to allow setting value of "transparent" (now the default). Because of this new value for backgroundColor, backgroundAlpha now defaults to 1.
Changes in build 364 (2009/02/04)
    * Performance improvement for handling of TextFlow.hostTextLayoutFormat. The code now assumes that once set by the client the supplied object won't be changed. This avoids a copy.
Changes in build 363 (2009/02/03)
    * Performance work. Remove getCanonical from TextLayoutFormat.
    * Fix for RTE cancelling SplitParagraphOperation.
    * Fixing some float bugs.
