Delphi XE2 and TeeChart 9

Question

i download TeeChart Pro v2012 Evaluation, i'm working with Delphi XE2. I run the demo exe i found with the product, and i tried to reproduce the code about Gantt charts, more precisely the part to drag and drop the element of the Gantt. I got the following error: "TGanttTool is not declared" I was unable to find this object anywhere in the code, any idea?

Answer 1

It seems to work fine for me here. Simplifying the Mouse dragging example to the maximum, creating everything at runtime, here it is the minimum code to have a Gantt dragging example. Does it work for you?

uses VCLTee.Chart, VCLTee.GanttCh, VCLTee.TeeGanttTool;

var Chart1 : TChart;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1:=TChart.Create(Self);
  Chart1.Parent:=Self;
  Chart1.Align:=alClient;

  Chart1.View3D:=False;
  Chart1.Zoom.Allow:=False;

  with Chart1.AddSeries(TGanttSeries) as TGanttSeries do
  begin
    FillSampleValues(5);
    Marks.Visible:=True;
  end;

  (Chart1.Tools.Add(TGanttTool) as TGanttTool).Series:=Chart1[0];
end;

Maybe the problem is just in the paths in your IDE. Please check there aren't wrong references present in the library/search path. And check the correct ones (referencing TeeChart) are ont he top of the lists.
