Re: How to set an item can not be deleted, but can edit the content inside

You use very old version of ScaleRichView. Currently, the newest version is 8.5. So I highly recommend to upgrade.

Re: TRichView toolbar icon set - 2

Yes, we have plans for a new set that can be available as SVG too. But I cannot tell when it will be ready.

Re: Watermarking

You can remove background bitmap by assigning
RichViewEdit1.BackgroundBitmap := nil;
Or you can hide by assigning
RichViewEdit1.BackgroundStyle := bsNoBitmap;

Re: Watermarking

Do you want to draw this text in a background? You can assign a background bitmap with this text, or you can use OnPagePrepaint event to draw it when printing (or exporting to PDF using third-party tools).

Re: Version 17.6 and Addict 4

This is a normal way of switching between 64 and 32-bit platforms for a project.
It's usually safe, but as you can see, it's very simple to get round the "not compatible with 64-bit" mark of components. So you must be sure that the components in the project are 64-bit compatible.

Re: How to set an item can not be deleted, but can edit the content inside

Probably, I do not understand your requirements. rvprDeleteProtect must prevent the text item from deletion. But it does not protect from modifications, including character deletion. Normally, this option allows deletion of all characters except for the last character. But it EmptyWidth > 0, this op...

Re: How to set an item can not be deleted, but can edit the content inside

The simplest solution would be inserting an edit control in TSRichViewEdit, preferably TSRVEdit. If you want to implement it using a text item, assign the following properties of a text style for this item: Protection : [rvprDeleteProtect, rvprStyleSplitProtect, rvprConcateProtect] EmptyWidth : some...

Re: Undeclared Identifier 'ERichViewError' in RVColorCombo.pas

It was renamed to RVRulerBase.pas, to prevent name conflict with other third-party components. If you created a project with older version of TRichView, please read information about possible compatibility issues in the help file: https://www.trichview.com/help/version_history.html - for TRichView h...

Re: Performance of TRVMathItemInfo

You are right, the list of font names should be made global. Currently, a list of fonts is stored only if TRVMathDocObject is added to TRichView.DocObjects.

I made the changes, they will be included in the next update.

Re: Undeclared Identifier 'ERichViewError' in RVColorCombo.pas

ERichViewError is defined in RVTypes unit. RVTypes is included "uses" of RVColorCombo.pas. As I understand, the components were successfully installed, including RichViewActions. This means that Delphi was able to compile RichViewActions, including RVColorCombo.pas. And the problem is in the specifi...

Re: Unsupported Picture Format (Trial limitation?)

1) TRichView supports Delphi 10. As well as Delphi 10.1, 10.2, 10.3. Everything is included in TRichView trial, so you can test TRichView in new versions of Delphi. 2) Your file contains PNG and JPEG image. In Delphi 5, JPEG images are supported, because Delphi 5 includes TJPEGImage class. However, ...

Re: LoadFFMpegLibraries fails for a specific path

I think the best solution would be switching the current directory to the FFmpeg directory, load libraries, then switch the current directory back.
