- RichView 1.9.10.2
- Full source code (without help and demo projects)
- -------------------------------------------------------
- HELP
- Help file:
- http://www.trichview.com/rvfiles/rvhelpfile.zip
- Demos for Delphi:
- http://www.trichview.com/rvfiles/delphidemos.zip
- Demos for C++Builder:
- http://www.trichview.com/rvfiles/cbdemos.zip
- All the files above in one zip:
- http://www.trichview.com/rvfiles/rvhelp.zip
- =====================================================
- COMPATIBILITY ISSUES:
- - HTML tag names, color constants, CSS names are saved in lower case
- - SaveHTMLEx does not use the following attributes for cells and tables any more:
- bordercolor, bordercolorlight, bordercolordark, background, bgcolor.
- CSS style is used instead. These attributes are not standard.
- - table layout algorithm: when there is not enough space for columns having
- widths specified in pixels, they are decreased proportionally
- (previously, only rightmost columns were decreased)
- - table grid is not shown in readonly editors any more
- =====================================================
- 1.9.10.2
- Processing for WM_GETTEXT, WM_GETTEXTLENGTH, WM_SETTEXT is disabled for Delphi 2005
- (because it conflicted with D2005 VCL's processing of these messages)
- 1.9.10 BETA
- impr: in loading indents of bullets&numbering from RTF saved by MS Word
- fix: TDBRichView, HTML export, bidirected Unicode text, adding Unicode text
- 1.9.9 BETA
- new: "smart popups" (analog of MS Office's "smart tags").
- It's a small button appearing in the corner of the current item.
- Only one such button can be displayed at the same time.
- new: property TRichViewEdit.SmartPopupProperties, contains subproperties:
- - Color, HoverColor, LineColor, HoverLineColor, ImageList, ImageIndex -
- define visual appearance of smartpopup button;
- - Hint - hint of smartpopup button;
- - ButtonType (DropDown (triangle)/ShowDialog (3 dots)/Simple) - defines
- how the popup button looks like in hot state
- - ShotCut (default Shift+Ctrl+Down) - allows using keyboard instead of mouse
- - Menu - popup menu to display on click (or on ShotCut)
- new: property SmartPopupVisible - shows/hides the popup button for the current
- (at the position of caret) item. Editor hides this button automatically
- on document change or clearing. Since smart popup works only for
- the current item, you must ensure that it is displayed for the current item -
- update it in OnCaretMove event. Even if this property is True, reassigning
- True to it makes sense, because it links the smart popup to the current item.
- new: event OnSmartPopupClick - allows implementing your own effect when clicking
- the smartpopup button (or on pressing ShortCut). If you use menu, it's not
- necessary to process this event.
- new TRichViewEdit.SmartPopupProperties.SetButtonState(Hot: Boolean);
- Call SetButtonState(True) to fix the button in the "hot" state. It's useful
- to do this when you display your own dropdown window for the button.
- Call SetButtonState(False) to return it back to normal.
- 1.9.8
- impr: Ctrl+Up and Ctrl+Down scroll the document down/up instead of moving caret.
- impr: Ctrl+Left, Ctrl+Right, Ctrl+Delete take Delimiters into account.
- fix: in db components
- chg: rvoFastFormatting is included in Options by default (it affects existing projects
- where TRichView has default value of Options)
- chg: support for C++Builder 1 and 3 is dropped (actually, it did not work since 1.9.3 or
- even before)
- 1.9.7 BETA
- impr: much faster reformatting! (thanks to Rob Schoenaker)
- It's faster by 50-100%.
- If you include rvoFastFormatting in Options, it will be faster up to 400%!
- (works only under WinNT/2k/XP;
- if this option is included, formatting procedure use a lot of system resources,
- but they are released immediately after finishing formatting).
- Highly recommended to try.
- This option can also be applied to TRVPrint (RVPrint.rv.Options) and
- TRVReportHelper (RVReportHelper.RichView.Options).
- new: new options for TRichView.BackgroundStyle: bsTopLeft, bsTopRight, bsBottomLeft,
- bsBottomRight (define the position of background bitmap).
- new: TRichView.LoadFromStream - loads data from the Stream autodetecting its format
- (RVF/RTF/text). The last parameter (IsTextUnicode) specifies is the text Unicode.
- It can be one of:
- rvynaNo - read text as ANSI
- rvynaYes - read text as Unicode
- rvynaAuto - autodetects ANSI/Unicode (false detection is very possible)
- impr: table.VisibleBorders is saved to HTML and RTF
- fixes
- 1.9.6 BETA
- new: TJvGIFImage (from Project JEDI's JVCL, http://jvcl.sourceforge.net) animation.
- To enable it, include RVJvGifAnimate in your project. More info: see in v1.9.5
- impr: rvespAlt (see TRVExtraItemStrProperty type) property can be applied
- to bullets and hotspots
- new: Hint: String property for table cells (unlike item hints, they cannot
- be altered by OnItemHint event)
- impr: you can define which characters to show in ShowSpecialCharacters mode.
- They are listed in RVVisibleSpecialCharacters (global variable in RVStyle.pas)
- It's a set of (rvscSpace, rvscNBSP, rvscParagraph, rvscSoftHyphen).
- By default, it lists all the options.
- impr: you can allow saving explicit page breaks in text files/streams.
- Set the global variable RichViewSavePageBreaksInText (from CRVData.pas) to True.
- new: the following Windows messages are processed by TRichView:
- EM_GETSEL, EM_SETSEL, EM_GETTEXTRANGE, WM_GETTEXTLENGTH, WM_GETTEXT, WM_SETTEXT.
- If you do not need these messages, you can define RVDONOTUSELINEARPOSITIONS in RV_Defs.inc.
- It slightly reduces exe-file size.
- new: ability to delete unused styles even if they are used by several documents.
- New methods:
- MarkStylesInUse(data) - marks all styles used in RichView.
- DeleteMarkedStyles(data) - the first call deletes the marked styles from RVStyle.
- All calls adjust references to styles in documents.
- See Examples.txt.
- fix: in editing and RTF export
- 1.9.5 BETA
- new: ANIMATION: direct support for animated images.
- New property: AnimationMode:
- - rvaniDisabled: all animation is completely disabled.
- If images are added/updated in this mode, they cannot be
- animated (even if different mode is set later).
- This mode saves system resources.
- - rvaniManualStart (default): animation starts when calling
- StartAnimation and stops when calling StopAnimation.
- - rvaniOnFormat: animation starts when calling Format and
- stops when calling Clear. StartAnimation and StopAnimation
- work as well.
- rvaniManualStart is set by default because rvaniOnFormat
- may cause problems in some existing applications.
- Animation must be stopped when you call viewer-style
- methods like DeleteItems. If you simply load and edit
- documents, set this mode to rvaniOnFormat.
- Supported animations:
- 1) TGifImage by Anders Melander.
- http://www.torry.net/vcl/graphics/gif/gifimage.exe (original)
- http://www.trichview.com/resources/thirdparty/gifimage.zip (update)
- Include RVGifAnimate.pas in your project to enable this animation.
- 2)TBitmap. Bitmap is sliced into frames (rvepImageWidth x rvepImageHeight)
- arranged in rows and columns. Animation is enabled if you set nonzero
- rvepAnimationInterval in positive value (animation delay in 1/100 of second)
- See the help file on TRVExtraItemProperty type about rvep*** values.
- Known problems: such bitmaps are still printed and exported stretched
- instead of exporting one frame.
- Note: unlike drawing/saving/loading of images, there is no standard
- graphic methods for animation. Because of this, a special
- wrapping code is required for supporting each new animation type.
- You can post your requiest for new animation types in newsgroups or
- svt@trichview.com.
- fix: RTF export
- 1.9.3 BETA
- impr: support for the word joiner Unicode character (code $2060).
- This character is invisible and it disallows line breaking
- before and after it. A speciall support is required because
- almost no font has a glyph for this character.
- Note: it works propely only if inserted in the middle of a
- text item.
- chg: if image was not returned in OnRVFPictureNeeded event, this event
- is called second time with the value of rvespImageFileName property
- in the Name parameter (if value of this property was stored for
- this item).
- fix: keep-with-next option did not work for paragraphs before tables
- (if tables were printed on several pages)
- test: if you set RichViewShowGhostSpaces variable to True, spaces hidden between
- lines will be shown in rvoShowSpecialCharacters is in TRichView.Options
- 1.9.2.1 BETA
- fix: in table.VisibleBorders implementation
- chg: table grid is not shown in readonly editors any more
- More exactly, it is shown using global variable RichViewTableGridStyle2 (default value: psClear).
- The same pen style is used for drawing table grid in viewer.
- For editors, RichViewTableGridStyle variable is used (default value: psDot)
- 1.9.2 BETA
- new: packages for Delphi 2005 (Win32): RVPkgD9 and RVDBPkgD9.
- new: table.VisibleBorders property having the same meaning as cell.VisibleBorders.
- Direct assignment to this property cannot be undone/redone, use table.SetTableVisibleBorders
- for that
- new: TRichViewEdit events: OnOleDragEnter, OnOleDragOver, OnOleDragLeave, OnOleDrop.
- These events are called when user drags and drops data in the given RichViewEdit.
- These events are related to OLE d&d used by TRichView (VCL d&d events - OnDragOver,
- OnDragDrop - are called when dragging Delphi component over TRichViewEdit. VCL d&d
- is not processed by TRichViewEdit itself)
- OnOleDragEnter - user drags the mouse into the editor. Indicates whether a drop
- can be accepted, and, if so, the effect of the drop.
- OnOleDragOver - user moves the mouse over the editor. Called only if the dragging
- was accepted in OnOleDragEnter.
- OnOleDragLeave - user drags the cursor out of the editor or cancels the current d&d operation.
- OnOleDrop - the user completes the d&d operation into the editor. Allows you to insert
- data in your own format.
- Parameters of these events:
- DataObject: IDataObject - dragged data (IDataObject is declared in ActiveX unit);
- Shift: TShiftState - keyboard state;
- PossibleDropEffects: TRVOleDropEffects - a list of allowed operations, set of
- rvdeCopy, rvdeMove, rvdeLink.
- DropEffect - on input, a d&d operation which editor would choose by default.
- On output: For OnOleDragEnter and OnOleDragOver, the operation that you want to
- do with the dragged data (one of PossibleDropEffects, or rvdeNone if you
- do not want to accept it).
- For OnOleDrop, the operation that you have performed (one of PossibleDropEffects,
- or rvdeNone if you cancelled the insertion). If it is rvdeMove, it instructs
- to delete the dragged object from its source location. This value is
- used only if you set DoDefault=False, otherwise the editor does the default
- processing. If you insert some data in RichViewEdit in this event, they are
- automatically selected afterwards.
- Limitation: when dragging from the same editor, it decides by itself
- whether it should move or copy data, and it ignores DropEffect returned by OnOleDrop.
- new: rvtoNoCellSelect option for TRVTableItemInfo.Options.
- If included, multicell selection by mouse is not allowed (remove also
- rvtoRowSelect, rvtoColSelect to disallow making multicell selection completely).
- fix: fixes and tweaks in table layout algorithm.
- fix: sometimes a wrong code page was chosen for the conversion when applying
- Unicode style to non-Unicode text.
- 1.9.1.8
- new: TRichView.RTFReadProperties.StoreImagesFileNames: Boolean (default False).
- If you set it to True, filenames of external RTF images will be stored in
- rvespImageFileName item property of read images, and you will be able to use
- them when storing HTML.
- fixes
- 1.9.1.7
- new: loading and saving PNG images in RTF.
- To enable this feature, call the procedure RV_RegisterPngGraphic
- for the class representing PNG image. For example, if you use
- PngObject (http://pngdelphi.sourceforge.net/), call
- RV_RegisterPngGraphic(TPngObject);
- fixes
- 1.9.1
- new: rvsoXHTML option for SaveHTMLEx (ignored by SaveHTML).
- If set, output is XHTML.
- new: rvsoUTF8 option for SaveHTML and SaveHTML.
- If set, HTML/XHTML file has UTF-8 encoding
- Pros and cons:
- pro: if you use Unicode, this option generates much more compact files
- (for non-Western languages)
- pro: if you do not use Unicode but use text of different charsets,
- this option allows saving multilingual HTML (was not possible before)
- con: if you do not use Unicode this option may generate files of larger
- size (for non-Western languages). So the only case when it's not very good -
- if your document is not Unicode and all text is of the same charset.
- con: RvHtmlImporter does not support UTF-8 yet
- fix: minor fixes
