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 nonzero value

Text style properties can still be deleted after setting them

Hello, administrator.

My project is just text, and I can't use TSRVEdit. I set the [rvprDeleteProtect, rvprStyleSplitProtect, rvprConcateProtect] attribute you said, and it can be deleted in the text. Is there any other way to change?

Example: I just want to get the text content underlined in red in the attached image.

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 option allows deleting all characters, but empty text item is not deleted.

Sorry, I do not understand the example with red underline.

Hi administrator, the version number of my directory SRichViewEdit is v5.9.6. Do you need to upgrade?

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

Hello administrator,
I have updated the latest version I purchased, but I have set it as you said, I can still delete the rectification project, my code is as follows:

RVStyle1.TextStyles[11].EmptyWidth := 1;
RVStyle1.TextStyles[11].Protection := [rvprDeleteProtect, rvprStyleSplitProtect, rvprConcateProtect];

Can you create a simple project reproducing this problem and send it by email?


PS: after reading your post in the private forum, I think that there is a possibility that you still compile the project using older version of ScaleRichView. I may be the reason of this problem.
