Druckfunktion fragen

  Alt 13. Dez 2006, 12:34
ich habe diese Druckfunktion gefunden zum ListView drucken
Damit habe ich 2 Probleme

a) die linien die da gezeichnet werden sidn mir zu dünn!
b) Möchte ich in jeder Zeile ne Linie!

wer kann mir dabei helfen?

Delphi-Quellcode:
procedure PrintListview(oListView: TListView; PrintDialog: TPrintDialog; lvTitel: string);
var
  pWidth, pHeight, i: Integer;
  v, h: Real;
  CurItem, iColumnCount: Integer;
  aCols: array of Integer; // Delphi 5
  iTotColsWidth, iInnerWidth, TopMarg, LinesOnPage, CurLine, TekstHeight, CurCol: Integer;
  CurRect: TRect;
  CurStr: string;
  CurLeft, NumPages, TmpPos: Integer;

begin
  if PrintDialog.Execute then
  begin
    iColumnCount := oListview.Columns.Count;
    SetLength(aCols, iColumnCount + 1);

    pWidth := Printer.PageWidth;

    v := (pHeight + (2 * GetDeviceCaps(Printer.Handle, PHYSICALOFFSETY))) / (29.7 * 0.95);
    //0.95 is a strange correction factor on the clients printer
    h := (pWidth + (2 * GetDeviceCaps(Printer.Handle, PHYSICALOFFSETX))) / 21;

    // calculate total width
    iTotColsWidth := 0;
    for i := 0 to iColumnCount - 1 do
      iTotColsWidth := iTotColsWidth + oListView.Columns[i].Width;

    // calculate space between lMargin and rMargin
    aCols[0] := Round(1.5 * h); //left margin ?
    aCols[iColumnCount + 0] := pWidth - Round(1.5 * h); //rigth margin ?
    iInnerWidth := aCols[iColumnCount + 0] - aCols[0]; // space between margins ?

    //calculate start of each column
    for i := 0 to iColumnCount - 1 do
      aCols[i + 1] := aCols[i] + Round(oListView.Columns[i].Width / iTotColsWidth * iInnerWidth);
