TCustomRichViewEdit(RichViewEdit1.InplaceEditor) returns the inplace editor of table inside RichViewEdit1 (can be nil if inplace editor is not activated). This editor, in its order, can have its own inplace editor (for editing cell of nested table) and so on. The latest inplace editor is available a...

Nothing too complicated, of course.
The only problem - the positioning relative to the line bottom/middle/top must be done after the calculation of the line vertical position, while baseline-related position does not require a post processing.

This is quite a complicated logic, there are no methods to make it simple. General direction - in OnChange, use SearchText (or other method) to find the character, then use SetSelectionBounds, ApplyStyleConversion, InsertText. Similar work is performed in the simple RichViewEdit-based syntax highlig...

Unfortunately, generally it's not possible, if you do not know text height. Image can be positioned relative to the text base line, not relative to the middle of line. More options will be implemented in future, but not now. Properties for vertical text positioning: 1) VAlign has 2 values: - image b...

Hmm, it should be safe to free the old control here.
Calling TRichView(Sender).RemoveControl(lOldCtrl) is not needed. What if you remove it?

The seach selects the found string.
Call ApplyTextStyle or ApplyStyleConversion to change the selection font.
A simple example can be found in Demos\Delphi\MultiDemo\, the last subdemo.

Should it be an editing operation (that can be undone/redone by user)? If not, the code is below: procedure DeleteBlankLines(RVData: TCustomRVData); var i,r,c: Integer; table: TRVTableItemInfo; begin for i := RVData.ItemCount-1 downto 0 do if RVData.IsParaStart(i) and (RVData.GetItemStyle(i)>=0) and...

Well, really? :)

It's not so hard to make a "quick and dirty" solution for this problem.
So, if you are satisfied with other TRichView feature, consider this function done

Unfortunately, it's not so trivial.

OnSaveRTFExtra can be used to save plain text headers, or headers with some simple formatting.

Saving arbitrary TRichView document as RTF header is not possible in the current version.

But they will not be loaded as TCharts ...
