I'm a brand new user, have some findings and a Ticker demo AV

Hello folks,

I'm not sure if this is the right place to reach the Streema support.
I am testing the TeeGrid, under FMX at the moment and how to comments on this.

1. I'm sorry to say, but the install experience is a little bit poor, not the non-brainer I expected.
The setup requires .NET 3.5 SDK, which I usually have not install, to keep my VM's clean.
So I have to evaluate a process, in which I copy the files from another VM to the desired VM without Delphi with Delphi 11.3

This was my process:
- Install on machine VM1 which may have .NET 3.5 installed
- install .NET3.5 if needed, after such new install a re-boot OS is needed
- create the desired "fake" folder structure, under which you want to install TeeGrid
- install TeeGrid under thisdesired folder
- accept Direct internet ( the proxy was untested )
- install on VM1 ( without Delphi )

- copy sources from VM1 to VM2, where Delphi is installed under desired folder
- Run TeeGridRecompile.exe, to install and compile in Delphi
- Choose # IDE-Version
- Choose the right platforms ( Remove Macos ARM, iOS ARM Simulator and Linux, in my case )
- Choose # Install packages into IDE
- Choose # Debug packages compilation
- Choose # Verbose
- Choose # Packages TeeGrid for Firemonkey ( in my case )
- Choose # Use LiveBindings ( in my case )
- BUILD
- if Destination folder does not exists, create it and re-try BUILD

At least, this process worked for me.

I found that afterwards the following environment variables were added:
GRID_INCPATH d:\Projects\Library\Steema\TeeGrid\Sources\..\Compiled\Delphi28.win32\Include
GRID_LIBPATH d:\Projects\Library\Steema\TeeGrid\Sources\..\Compiled\Delphi28.win32\Lib
GRID_SRCPATH d:\Projects\Library\Steema\TeeGrid\Sources
Please note the \..\ , this looks like a bug to me.
Not sure if that works.

Nevertheless, those environmental variables seems not to be used.
The folders under Delphi path were added hard-coded
- Library Path d:\Projects\Library\Steema\TeeGrid\Compiled\Delphi28.win32\Lib
- Browsing Path d:\Projects\Library\Steema\TeeGrid\Sources
- Debug DCU Path d:\Projects\Library\Steema\TeeGrid\Compiled\Delphi28.win32\Lib

After running the tests, under Win32 first, I found some issues with the TickerDemo, from the TeeGridFeatures application.
That is a very nice feature, unfortunately when closing, the app it might throw an AV randomly.
After a fast check, I found a possible workaround in the Tee.Grid.Ticker unit.

Code: Select all

Destructor TGridTicker.Destroy;
begin
  Enabled := False;   //Fix AV, Disable
  IThread.Terminate;  //Fix AV, Terminate myself
  IThread.WaitFor;    //Fix AV, Wait until last loop finished

  IThread.Free;
  FLowerBrush.Free;
  FHigherBrush.Free;
  inherited;
end;

I would love to see the next version installer without requirement for .NET 3.5.
I hope that comments here help to improve the TeeGrid.

Still more tests will come, but I'm quite happy with that nice grid so far.
Looks exactly what I was looking for, for the cross-platform and VCL support.
Thanks for that nice component.

Hello,

Sorry for the delayed reply here.
We are still studying all the issues reported but we'll do some changes, hopefully in all of them.

- .NET dependency.
I think we'll be able to change the utility to avoid that dependency.

- Environment variables and paths.
We have to revise the creation of all these variables and registry keys.

- Access Violation at Ticker.
I've been able to reproduce the problem (#2668), and I can confirm the code suggested fixes it, so I'll add it.

Thanks for the feedback.
