TQRChart constant flicker with version 7.07

CArends · Post by **CArends** » Tue Jun 13, 2006 1:57 am

I am having a problem with TeeChart 7.07 and TQRChart flicker. I have read other posts on this topic and cannot figure out how to solve this problem from the responses that I have read. The notes say it shouldn't happen, the administrators in this forum say it shouldn't happen, but it's happening for me in both BDS2006 and BCB6.

First, my license doesn't allow me access to the TeeChart source (I do have the TQRChart source though). This means that I do not have access to the TeeRecompile tool which one of the replies for a similar post referred to. So all compiling that goes on is done using the IDE.

I do not have duplicate .lib, .dcu, .obj, .dcp, .bpi, .bpl, or .pas files. When recompiling I have removed from the component palette, deleted all binary files, and performed a complete rebuild.

The flicker happens for me in the IDE and from an application in which I use QuickReport Design for design-time creation of reports. This application can be compiled with or without packages with the same flicker result. The reason I mention this is to emphasize that the problem is not due to duplicate BPL files since the standalone EXE doesn't make use of BPL files.

I have patched the problem by commenting out the contents of TQRDBChart.Invalidate. This causes the flicker to stop but I'm not sure this is the appropriate solution and I haven't fully tested it. For reference this is the code that I commented from TQRDBChart.Invalidate:

if AutoRepaint and Assigned(Parent) then
Parent.Invalidate;

I have TeeChart 7.07, and QuickReport 4.03.

Thank you for your time.

Hi CArends,

As said in this other message, the QrTee.pas version in the binary installers doesn't fix the issue. I have already sent you the QrTee.pas included in v7.07 sources which fixes the issue.

Thank you for the email and the new QrTee.pas file. By using this file the problem is fixed.

I had already read the forum thread you referred me to. There were no instructions in there (that I saw) on how to retrieve the correct QrTee.pas file other than to write a forum question or send a support email request. Perhaps Steema could put the file in the downloads area for people to download on their own.

Thanks again!

You're welcome CArends,

You are right, for now there is now other way to obtain that QrTee.pas version. We are thinking about what to do on that field and also some other issues found in v7.07.

I have the same problem.
I installed TeeChart7.07 and TQRChart flickers in design time and run-time.
I use BCB6.

Hi dg11,

I've just sent you the qrtee.pas version with the fix to your forums profile e-mail address.

Thank you for your fast reply.
I Solve the problem with "TeeChart7.07SourceCode".

1. Uninstall "TeeChart7.07Builder6" with Custom option.
2. Install "TeeChart7.07SourceCode"
3. Run "Steema TeeChart7.07Sourcecode\Recompile"

Then the problem didn't appear.

Hi dg11,

Yes, the issue is already solved in the source code release. In fact, the qrtee.pas version I sent is the one in the source code installer.

Hi Pep,

I have also the same problem with TeeChart7.07. I use BSB6 and TQRChart flickers in design time and run-time. I used TeeChart7.06 before (same problem).

Thanks for your assistance,
Ralf
