Still cannot use palette tool

[johnnix]

Fresh installation of 10.4.1, only component installed TChart and I still get the error message.

Hello,

Are you trying to add the Legend Palette tool into a new chart? I'm doing that in a new application without errors.
If that works in a new application but still fails in a more complex one, please try to arrange a simple example project we can run as-is to reproduce the problem here.

After 2 years, a new fresh Delphi 11 installation and fresh TeeChart installation (latest source code) I still cannot use this tool.

Hello,

I've tried it again without issues.
Please provide more information as asked in my previous message so we can take a deeper look.

Some time ago I sent you a sample project, here is a new one, it will most probably work ok with you. I need someone to provide some insights on how to succesfully locate the source of the issue.

[Yeray]

Hello,

Indeed, I couldn't reproduce any error with that project.
Could you please try creating it by code?

Code: Select all

var ChartTool1: TLegendPaletteTool;

procedure TForm1.FormCreate(Sender: TObject);
begin
  ChartTool1:=TLegendPaletteTool.Create(Chart1);
  Chart1.Tools.Add(ChartTool1);
  ChartTool1.Series:=Series1;
end;

... once the mouse enters the chart area the same happens

Hello,

... once the mouse enters the chart area the same happens

No errors here with v2022.34 or v2022.35 in RAD 11.1.

it will most probably work ok with you

Do you have any idea why the same project would work fine in one environment and not in a different machine with the same environment?
I can only think on trying to find differences between both environments.

Hello,

I have no idea what is going on, I get the same behavior under my Windows 10 VM running Delphi 10.4, under my Windows 11 VM running Delphi 11 and under my desktop computer. I have no other computer to try it ...

Can you please send me a simple executable to run here?

[Yeray]

Hello,

Sorry for the delay here.

Can you please send me a simple executable to run here?

Sure, find it here. I've tested it in a Win11 VM and it seems to work fine.

[johnnix]

Hello,

No problem, as I suspected the error is still here! Now what?!

[Yeray]

Hello,

I'm sorry for the lack of reply here.
Have you found any configuration that may be explaining this?

[johnnix]

Nothing so far

Hello,

I have tried this in a new environment. Runs ok. Is it possible that your test machines are running security software that may be inhibiting the creation of windows objects/handles? Perhaps running the example across several machines may give a hint by more easily identifying what machines generate/don't the error. I'm assuming that you have machines that do not all run the same setup and that are able to run the example without an issue.
