Incompatible error when calling VTAccessibilityFactory.GetAccessibilityFactory.CreateIAccessible(Self);

[maddsen]

Self=TVTBaseAncestorVcl

but ATree is expected.

TVTAccessibilityFactory.CreateIAccessible(ATree: TBaseVirtualTree): IAccessible;

So system hangs.

unit VirtualTrees.BaseAncestorVCL;
unit VirtualTrees.AccessibilityFactory;

Regarding Version Delphi 12 and VSV 8.03.
I see many changes that happens from the time I first loaded and the latest version of VirtualStringView 8.03.
so maybe its not possible to advice without all details .
How is it possible to findVirtual_Treeview version number in one or other units like VirtualTrees.pas? Or is it only headers in Git that show the version numbers?

It is not included there. It depends on which release you download.

I added the unit VirtualTrees.AccessibilityFactory to the demo project Advanced and here to the unit GeneralAbilitiesDemo and the project compiles, no compiler errors.
