[Chart Legend] Change cursor when over the legend

bertrod · Post by **bertrod** » Wed Feb 15, 2006 9:31 am

Hello,

Is it possible to change the cursor when the mouse is floating over the legend, like with the axis and series ? I can't find any cursor property in the legend class.

Hi bertrod,

Yes, you can do this:

Code: Select all

procedure TForm1.Chart1MouseMove(Sender: TObject; Shift: TShiftState; X,
  Y: Integer);
begin
  if Chart1.Legend.Clicked(X,Y) <> -1 then Chart1.OriginalCursor:=crNoDrop;
end;

Thanks.

I have also a problem with the annotations : if I change the annotation's cursor, the dragging action is not fluently anymore.

You can see this in the ChartOffice program : if you create an annotation and then change its cursor to handpoing, you'll see that there are little problems when you drag it. Is it a bug ? And is there a way to correct it ?

Hi bertrod,

I'm not able to reproduce that problem using TeeChartOffice v3 (the version shipped with TeeChart Pro v7 VCL). Which TeeChartOffice version are you using?

I have the version 3.0 of TeeChartOffice.

1. Create an annotation
2. Move it somewhere
3. Dbl-click on it to edit it
4. Change the cursor to Handpoint
5. Now click on the left of the annotation, and move it to the right

In my version, the annotation is moved only the mouse pointer is leaving the shape. So when i move the mouse, the annotation is moving in a jerky way, like stepwise, instead of fluently.

Hi bertrod,

I'm still unable to reproduce the problem here following your steps and using TeeChart Pro v7.06 VCL. Which TeeChart version are you using?

Thanks in advance.

I have TeeChart Pro v7 , i can't find the exact version number.

I noticed that this "jerky" dragging happens when I'm using a cursor which is not the default one. It happens only for annotations.

Is the annotation moving fluently in your version ?

Hi bertrod,

Yes, it moves fluently in my version whichever the cursor is. To know which TeeChart version you have you can right-click on a TChart in a form. However, you could try downloading v7.06 from our Customer Download Area.

I have the 7.04 version.

Can I be sure that upgrading my current version won't cause problems with the current code

Narcís · Post by **Narcís** » Wed Feb 15, 2006 3:15 pm

Yes, v7.06 is fully backwards compatible with v7.04 and has some additional features and bug fixes.
