Ok, let we have RichViewEdit1: TRichViewEdit, linked to RVStyle1: TRVStyle. TextStyle: TFontInfo; // form's variable Reading current text format: TextStyle.Free; TextStyle := TFontInfo.Create(nil); TextStyle.Assign(RVStyle.TextStyles[RichViewEdit1.CurTextStyleNo]); Applying to the selection: var Sty...

As for copying from TRichEdit, it's simple.
Use RichEdit.Lines.SaveToStream to write, and RichView.LoadRTFFromStream to read.
Formatting will be kept, assuming that
1) RichEdit.PlainText = False
2) RichView.RTFReadProperties.TextStyleMode= RichView.RTFReadProperties.ParaStyleMode=rvrsAddIfNeeded.

As for the given visual layout, you can implement it using tables. Table with 2 columns and 1 row. In the first cell: 'Contest:' In the second cell: field which will be replaced to the formatted document. As for implementing fields where values are arbitrary formatted documents, see Demos\Delphi\Ass...

j&b, so, as I understand, you need to create a paragraph style with the given tab stops to add some text lines formatted with this paragraph style. { This function returns index of paragraph style with the specified collection of tabs. If such paragraph style does not exist, this function adds i...

Pieter, your code clears all existing tabs and then adds new tabs. My code adds new tabs in addition to the existing tabs. Without clearing, you should search if some tab exists at the given position (using ParaInfo.Tabs.Find), and, if exists, update its properties instead of adding a new tab. Using...

Ok. Assuming that you do not use RichViewActions... All editing operations on paragraph attributes, including tabs, must be implemented using ApplyParaStyleConversion procedure + OnParaStyleConversion event. How to add this command to the demo in Demos\Delphi\Editors\Editor 2\: Open Unit1.pas. Find ...

GetTextLen simple uses WM_GETTEXTLENGTH message. Processing of WM_GETTEXT, WM_GETTEXTLENGTH, WM_SETTEXT was disabled for Delphi 2005 and 2006, because it conflicted with VCL implementation. Sorry, I do not plan to restore them. EM_GETTEXTLENGTHEX is not supported. Use the functions RVGetTextRange an...

Confirmed. It may happen when previewing text formatted with raster (not TrueType) font.
Fix: Open RVStyle.pas, find two calls of RVU_GetTextExtentExPoint, change the 3rd parameter from Width*2 to $FFFFFFF.

You should be able too see it now.

Sorry, no

As en edting operation (which can be undone by user)? For the selected paragraphs?

Yes, document should be reformatted after changing "show special characters" mode. Showing/hiding spaces and paragraph marks does require reformatting, but showing/hiding some Unicode characters (such as soft hyphens) requires reformatting.

Call RichViewEdit.Reformat.

Sorry, I am not sure that I understand the question.
1) What code is in this button's OnClick
2) Please give me examples of document text:
a) text what you want
b) text what appears

This problem was easy to fix. In CRVData.pas, in TCustomRVData.SaveRTFToStream, the following code if (Level=0) and (StartItem<>EndItem) and IsParaStart(EndItem) and (GetItemStyle(EndItem)>=0) and (Items[EndItem]='') then RVFWrite(Stream, '\par'); was changed to: if (Level=0) then RVFWrite(Stream, '...

Format does not store the caret position, because Format is usually called when document is not formatted, so the caret position is undefined before its call.
If document is already formatted, why do you can Format?
