Yes, I plan to improve OnURLNeeded event (probably completely remove it and

make a new event - OnWriteHyperlink).

But I think I hit the limit on incompatibilities for one version, so I'll

make changes only after the next release.

I do not think that there will be too many updates before the release (I

plan two).

Do the <span>s and <p>s really hurt your code?

Can you give an example?

Your code for loading and saving strings are correct.

Controls should be saved automatically, without raising events.

Did you register their classes with RegisterClasses?

This code extends selection to the complete item(s):

var StartNo, EndNo: Integer;

StartOffs, EndOffs: Integer;

rve: TCustomRichViewEdit;

rve := RichViewEdit1.TopLevelEditor;

rve.RVData.GetSelectionBoundsEx(StartNo, StartOffs, EndNo, EndOffs, True);

if (StartNo<>EndNo) or (StartOffs<>EndOffs) then begin

if StartOffs>=rve.GetOffsAfterItem(StartNo) then

inc(StartNo);

if EndOffs<=rve.GetOffsBeforeItem(EndNo) then

dec(EndNo);

end;

StartOffs := rve.GetOffsBeforeItem(StartNo);

EndOffs := rve.GetOffsAfterItem(EndNo);

rve.SetSelectionBoundsEx(StartNo, StartOffs, EndNo, EndOffs);

rve.Invalidate;

I hope this is what you want.

This example has a disadvantage: it always selects text from top to bottom,

even if the original selection was from bottom to top.
