In TeeChart Pro 7.07 version for C++Builder6
Cursor tool has property TSnapStyle:SnapStyle

ChartTool1->SnapStyle = ssVertical;

There is no such property in the version of a component for C++Builder2007
(TeeChart Pro v.7.12 Win32).
Without this property the cursor is drawn not on a series line.
Please back this property for version of a component for C++Builder2007 or fix this problem.

To Narcís: In my previous topic (21 Feb 2008 08:22 Cursor tool have't snap style... )
i have made a typing error. I have written "Style: TCursorToolStyle" though wished to write "SnapStyle: TSnapStyle". I ask to excuse.

Hi GAN,

yes, using this property in C++2007 there's an ambiguity with the 'Stdctrls::ssVertical'.
I've added this issue on our bug/wish to modify it for the next releases. In meantime a solution is to assign it by using :

Code: Select all

ChartTool1->SnapStyle = TSnapStyle(2);  // for Vertical..

Hi Pep,
Please, look into TeeTools.hpp (from TeeChart Pro v.7.12 Win32 C++Builder2007)
There is no SnapStyle property.
Compiler message: 'SnapStyle' is not a member of 'TCursorTool'!
Please back this property for version of a component for C++Builder2007

Hi GAN,

As you can see here, SnapStyle property was implemented for TeeChart Pro v8 VCL.

We have also checked that neither v7.07 for C++ Builder 6 nor v7.12 for C++ Builder 6 and 2007 have this property on their TeeTools.hpp.

Could it be possible that you used an evaluation version of v8 and their hpp replaced v7's?

Posted: **Fri Mar 07, 2008 10:47 am**

Hi Narchs!
No, i'm not using an evaluation version of v8.
v7.07 for BCB 6 has SnapStyle. And this is the last version with SnapStyle for BCB6.
v7.07 for BCB 2007 and any other has not SnapStyle.
Tell me please, have you any plans to add this property to v7 Pro?
Or i need to buy v8 Pro?

Posted: **Fri Mar 07, 2008 11:13 am**

Hi GAN,

I've checked revisions of v7 and v8 source code and I can confirm that SnapStyle was implemented in v8.

Could you please post the installer where you say this property appears to a place where we can download it and send us its URL at info at steema dot com?

Thanks in advance.

Hi Narchs!

You can download it from
http:\\www.diatehnn.ru\files\TeeChart7.07Builder6.exe

And you can see a little screen shot

Hi GAN,

Thanks for the information. We have added SnapStyle property in our v7 sources. I'll send you necessary files. You can use TeeRecompile tool for compiling and installing them on your IDE.

Hi Narcis, biggest thanks! The problem with cursor snap style is resolved.

But there is another one. In v7.12 for BCB 2007 and BCB6 center of cursor (crosshair) draws not on a series line.
It was before update of my installation and still after.

You can download example (source and executable) of this problem from
http:\\www.diatehnn.ru\files\CursorTest.zip

Hi GAN,

Hi Narcis, biggest thanks! The problem with cursor snap style is resolved.

You're welcome. I'm glad to hear that.

But there is another one. In v7.12 for BCB 2007 and BCB6 center of cursor (crosshair) draws not on a series line.
It was before update of my installation and still after.

This is because the chart is in 3D. Cursor is plotted at Z=0 coordinate while series doesn't have 3D dimensions as it is a TFastLineSeries. You have 2 options to solve this:

1. Set chart to 2D:

Code: Select all

	Chart1->View3D = false;

2. Change the TFastLineSeries to a TLineSeries.

Yes, you are right!
Thanks!

Hi, I've been looking for this SnapStyle property and I couldn't find it in my TeeChart 7.12 ver.

I can see that it suppose to be in 7.07, but how come it doesn't exist in my 7.12?

I have search through TeeChart 7.12 Full source code in the TeeTools.pas and SnapStyle just isn't there.

Thank you.

Hi ChainSmokinCoder,

I just sent you same files I sent to GAN.

Posted: **Mon Apr 06, 2009 9:07 pm**

I have received the files, much appreciated. However why aren't these put into TeeChart 7?

Please back SnapStyle property to TChartTool v.7.12 and high
