For example, you can use GetAllText from RVGetText.pas:
function GetAllText(rv: TCustomRichView): String;

As for the second question, I need more details to answer.

In order to include picture names, you need to modify GetItemText from this unit ("or (rv.GetItem(ItemNo) is TRVGraphicItemInfo)" is added):

Code: Select all

function GetItemText(rv: TCustomRichView; ItemNo: Integer): String;
begin
  if (rv.GetItemStyle(ItemNo)>=0) or (rv.GetItem(ItemNo) is TRVGraphicItemInfo) then
    Result := rv.GetItemTextA(ItemNo)
  else if rv.GetItem(ItemNo).GetBoolValue(rvbpAlwaysInText) then
    Result := rv.GetItem(ItemNo).AsText(0, rv.RVData, rv.GetItemText(ItemNo), '', True, False)
  else    
    Result := '';
end;
The same change must be done in GetItemText2.

PS: This example assumes that the picture text (which you want to insert in string) is stored in the item name (the first parameter of InsertPicture, can be read by GetItemTextA, changed by SetItemTextA).
But probably you want to insert "alternative text", stored in rvespAlt property (this property was specially added to store a text representation of image). In this case, text for images must be retrieved using GetItemExtraStrProperty method.

About the second question. I wanted additional information from you :)
Generally, it's not possible to restore items from text.
