Thanks, TW

RVStyle.TextStyles[i].Free and RVS.Textstyles.Delete(I) are equivalent (in

older version of Delphi, collections did not have method Delete).

These operators deletes one collection item - one text style.

Yes, if you want to delete 3rd and 5th style, you need to call

RVS.Textstyles.Delete(3);

RVS.Textstyles.Delete(4);

(

or it's easier to use reverse order

RVS.Textstyles.Delete(5);

RVS.Textstyles.Delete(3);

)

Note: RichView text items stores indices in the collection of text styles.

If you'll delete some text style, indices will not be adjusted.

RichView.DeleteUnusedStyles deletes unused styles and adjusts indices in the

document.

But method RVS.DeleteText styles is really obsolete.
