Several calls of this event make no problem in all demos and real applications that use TRichViewEdit/ScaleRichView. And none of them implement special processing for this.
This event is never called with incorrect parameters, so they are called several times with the same value of CurTextStyleNo.

Certainly, TrvActionPrint, TrvActionQuickPrint, TrvActionPrintPreview, TrvActionPageSetup do not work with ScaleRichView properly. It's obvious, because they use TRVPrint's repagination procedure and properties instead of ScaleRichView's procedure and properties. The most of these actions can be imp...

Similar code can be used to change controls to images. In this code, GetControlGraphic is your function returning graphic representation of the given control. You can use DrawControl function from CtrlImg unit, but it is not able to create images for all types of controls. { Inserting graphic item i...

Do you want to create PDF document consisting of several TRichView documents, with (or without) page breaks between them?
I am not sure how eDocEngine generates document, so I suggest simply to add all documents in the same TRichView, see http://www.trichview.com/forums/viewtopic.php?p=1002

Is it possible to create a project reproducing the problem and send it to me? You can use this code to detect error. It checks if the RichViewEdit1 content's Unicode mode corresponds to TextStyles[].Unicode. Only the first item is checked. uses RVItem; RichViewEdit1.Format; if (RichViewEdit1.GetItem...

Controls are saved in RVF by default (all their published properties are stored, except for links to other components and events).
In order to load controls, they must be registered using RegisterClass.
For example:
RegisterClass(TButton);
Call registering code one time before the first RVF loading.

Controls are not saved in RTF.
If you need to save them, you can use OnSaveComponentToFile event. You need to know RTF format to implement this event.
But there is still no way to load controls back from RTF.
If you need to store controls, use RVF (RichView Format) instead.

For the last page, you can use RVReportHelper.GetLastPageHeight.

This behavior is inherited from TRichViewEdit. Yes, in some cases, OnCurTextStyleChange can be called several times.
I do not think that this is a serious problem.

You use Lazarus version of TRichView. This is a port of the old freeware version of TRichView. It cannot load RTF.
As for printing, [rvdoImages, rvdoComponents, rvdoBullets] must be used instead of rvdoAll.

This bug is already fixed in the newer version of RVRuler.
No, I believe that TRichView.Get*** methods must generate exception when called with incorrect item index.

This code must work. But if you want to replace content of Document, call: Document.Clear; VRichView.SaveRVFToStream( Document, False ); instead of VRichView.SaveRVFToStream( Document, True ); Without clearing the stream, new information will be written to the end of the existing content. It may pro...

Please note that trial again requires new version of TRichView and RichViewActions

In addition, you can:
- for TRVTabItemInfo items, add #9 in text
- if objCell.GetRVData.IsFromNewLine(intCount), add #13#10
