Compatibility issues

The type of Sender parameter was changed from TSRichViewEdit to TCustomRichViewEdit for TSRichViewEdit.OnStyleConversion and OnParaStyleConversion events.
Two new parameters are added to TSRichViewEdit.OnPaintPage: Prepaint and Printing.
A new parameter is added to TSRichViewEdit.OnPaint: PaintRect.
The user can zoom the editor in/out using  Ctrl  + mouse wheel. So, if you assume that the editor has the fixed values of TSRichViewEdit.ViewProperty.ZoomPercent and ViewProperty.ZoomMode, assign ViewProperty.MouseWheelZoom = False.
TSRichViewEdit.ViewProperty.HeaderFooterShade is renamed to ViewProperty.MainDocumentShade. ViewProperty.HeaderFooterShade now has a different meaning.
TSRichViewEdit.PageProperty.PageWidth and PageHeight do not depend on the document display modes any more. Properties of the same names were added in TSRichViewEdit.ViewProperty.

Units of measurement

All properties and parameters measured in TSRichViewEdit.UnitsProgram have changed their types from Extended to TRVLength. At design time, you can see units of measurement for these properties in the Object Inspector.

By default, properties of all RVStyles in TSRichViewEdit are measured in pixels. To convert them to twips, call TSRichViewEdit.ConvertToTwips.

TsrvActionPageSetup displays values in TRVAControlPanel.UnitsDisplay, not in TSRichViewEdit.UnitsProgram.

To do: a precision of drawing and printing is still up to one screen pixel. A higher precision is planned in newer version.

Incremental printing

TSRichViewEdit has new properties: MinPrintedItemNo and MaxPrintedItemNo. If these properties define a subrange of items, only this subrange (and only the pages containing it) is printed.

These properties allow implementing an incremental printing: when the next portion of the document is ready, it can be printed below the previously printed fragment. This feature can be used for printing accounting journals, logs, etc.

New properties and methods

New properties:

TSRichViewEdit.BackgroundProperty.GlobalPageBackgroundColor allows to define document background color without saving it in RVF files.
TSRichViewEdit.ViewProperty.MouseWheelZoom allows to turn off a mouse wheel zooming

TSRichViewEdit.ViewProperty: MainPen, MainTitle, MainTitleColor, MainTitleFont allow drawing borders and label for the main document (like it is done for a header and a footer).
TSRichViewEdit.ViewProperty: PageWidth, PageHeight return page size as it is shown on the screen.

New methods of TSRichViewEdit:

GetItemAt returns the item at the specified coordinates.
Clear, Format (not new but improved) clears and format the editor completely, including header and footer

Flat makes the scrollbar look flat.

Modified methods of TSRichViewEdit:

GetItemPages, GetItemBounds, GetItemBounds100, GetItemCoords100 support item parts, so they can return more precise information.
