Change RTF document

Post by darkducke »

Hello, I am testing the component for the first time, looking for a solution that meets me, I need is change a few words in an RTF document and insert a table of items that are in a TStringGrid, the document already exists, must open to changes to save, without user intervention. I've seen some examples nothing like this can give me the ropes?
Thank you very much!

1) About headers and footers.
If you will use ScaleRichView, you can define headers and footers in a single editor, TSRichViewEdit. This is the simplest solution.
If you use TRichViewEdit, you need a separate editor for each header and footer. In the simplest case: one TRichViewEdit for the main document, one TRichViewEdit for header, one TRichViewEdit for footer. However, documents may have special headers for the first page and for even pages, so you need up to 7 TRichViewEdit controls. You can find an example in Demos\DelphiUnicode\Assorted\Printing\Headers

2) This procedure creates a table from a string grid:

Code: Select all

function ConvertStringGridToTable(Grid: TStringGrid; Edit: TCustomRichViewEdit;
  StyleNo, ParaNo: Integer): TRVTableItemInfo;
var r,c: Integer;
begin
  Result := TRVTableItemInfo.CreateEx(Grid.RowCount, Grid.ColCount, Edit.RVData);
  for r := 0 to Grid.RowCount-1 do
    for c := 0 to Grid.ColCount-1 do begin
      Result.Cells[r,c].Clear;
      Result.Cells[r,c].AddTextNL(Grid.Cells[c,r], StyleNo, ParaNo, ParaNo);
    end;
end;
Adding to the end of TRichViewEdit:

Code: Select all

var Table: TRVTableItemInfo;
begin
  Table := ConvertStringGridToTable(StringGrid1, RichViewEdit1, 0, 0);
  // define table properties, including column widths, here
  RichViewEdit1.AddItem('', Table);
  RichViewEdit1.Format;
end;
Adding to the end of TSRichViewEdit:

Code: Select all

var Table: TRVTableItemInfo;
begin
  Table := ConvertStringGridToTable(StringGrid1, SRichViewEdit1.RichViewEdit, 0, 0);
  // define table properties, including column widths, here
  SRichViewEdit1.RichViewEdit.AddItem('', Table);
  SRichViewEdit1.Format;
end;
3) For RTF, both loading and saving is supported. For DocX, only saving (it's possible to load DocX using converters and TRVOfficeConverter component, but converters may lose some formatting)
