用Ehlib二次开发报表打印程序,实现财务凭证的打印(三)

 2006-02-04 13:38:10 来源:WEB开发网   
核心提示: 4、打印表头,我将表头的各个部分划成了几部分,用Ehlib二次开发报表打印程序,实现财务凭证的打印(三),如我的凭证打印的地方,我就划成了五部分,,)6、打印汇总栏内容(代码较多,每部分按占百分比多少计算,如编制单位就占页面宽度的40%等PRocedure TF_printpreview.printpageheade
 

4、打印表头,我将表头的各个部分划成了几部分,如我的凭证打印的地方,我就划成了五部分,每部分按占百分比多少计算。如编制单位就占页面宽度的40%等

PRocedure TF_printpreview.printpageheader(pageheader: Tstrings);
var
  Headrect:Trect;
  count:integer;
begin
  pp_pz.Printer.Canvas.Font.Name:='宋体';
  pp_pz.Printer.Canvas.Font.Color:=clblack;
  pp_pz.Printer.Canvas.Font.Size:=9;
  pp_pz.Printer.Canvas.Font.Style:=[];
  gettextinfo;
  Amountprint:=Amountprint+round(0.8*textheight);//当前逻辑尺的位置
  for  count:=0 to pageheader.Count-1 do
  begin
   case count of
    0:
    HeadRect:=Rect(round(pp_pz.Printer.PageSet.LeftMargin),Amountprint,round(pp_pz.Printer.PageSet.LeftMargin+round(0.4*(pp_pz.Printer.PageWidth))),Amountprint+textheight);//编制单位比例
    1:
    HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right+round(0.16*(pp_pz.Printer.PageWidth)),Amountprint+textheight);//凭证日期比例
    2:
    HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right+round(0.14*(pp_pz.Printer.PageWidth)),Amountprint+textheight);//帐套号比例
    3:
    HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right+round(0.2*(pp_pz.Printer.PageWidth)),Amountprint+textheight);//凭证号比例
    4:
    HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right+round(0.1*(pp_pz.Printer.PageWidth)),Amountprint+textheight);//分页数号比例
   end;
   pp_pz.Printer.Canvas.TextOut(Headrect.left,headrect.top,pageheader[count]);
  end;
end;

5、打印表格头

procedure TF_mxzprint.printdetailheader(detailheader: Tstrings);
var
  drect,srect,jrect:Trect;
begin
   pp_pz.Printer.Canvas.Font.Name:='宋体';
   pp_pz.Printer.Canvas.Font.Color:=clblack;
   pp_pz.Printer.Canvas.Font.Size:=9;
   pp_pz.Printer.Canvas.Font.Style:=[];
   gettextinfo;
   Amountprint:=Amountprint+textheight;
   pp_pz.Printer.Canvas.Font.Size:=11;
   drect:=rect(PageRect.Left,Amountprint,PageRect.Left+round(0.3*(PageRect.Right-PageRect.Left)),Amountprint+2*textheight);
   drawtext(pp_pz.Printer.Canvas.handle,pchar('摘  要'),length('摘  要'),drect,DT_center or  DT_WordBREAK or DT_VCENTER or DT_SINGLELINE);
   addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom,drect.left,drect.top]);

   drect:=rect(drect.right,drect.Top,drect.right+round(0.4*(PageRect.Right-PageRect.Left)),srect.Bottom);
   drawtext(pp_pz.Printer.Canvas.handle,pchar('科目名称'),length('科目名称'),drect,DT_center or  DT_WORDBREAK or DT_VCENTER or DT_SINGLELINE);
   addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom,drect.left,drect.top]);
   drect:=rect(drect.right,drect.Top,drect.right+round(0.15*(PageRect.Right-PageRect.Left)),srect.Bottom);
   drawtext(pp_pz.Printer.Canvas.handle,pchar('借方金额'),length('借方金额'),drect,DT_center or  DT_WORDBREAK or DT_VCENTER or DT_SINGLELINE);

   addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom]);
   drect:=rect(drect.right,drect.Top,drect.right+round(0.15*(PageRect.Right-PageRect.Left)),srect.Bottom);
   addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom,drect.left,drect.top]);
   drawtext(pp_pz.Printer.Canvas.handle,pchar('贷方金额'),length('贷方金额'),drect,DT_center or  DT_WORDBREAK or DT_VCENTER or DT_SINGLELINE);

   addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom]);
   Amountprint:=amountprint+drect.Bottom-drect.Top;//+textheight;
end;

5、打印表格内容

(与上面相似,代码太多,略。。。)

6、打印汇总栏内容(代码较多,而且也相似,略)

7、执行打印功能

  pp_pz.Printer.BeginDoc;
  依次打印标题、打印、表头等

 PolyPolyline(pp_pz.Printer.Canvas.Handle,PolyPolyPoints.List^,PolyLengths.List^,PolyLengths.Count);  pp_pz.Printer.EndDoc;

关键:就两个函数PolyPolyline和DrawText而已!
