So part of the issue was that I was mixing `= object of RootObj` and `{.pure,
inheritable.}`.
But now I am having the following issue. I have:
type
NCollectionHandle*[T] {.importcpp: "NCollection_Handle<\'0>",
header: "NCollection_Handle.hxx", bycopy.} =
object of HandleStandardTransient
Run
When I compile this, I get the error:
Error: inheritance only works with non-final objects; for
HandleStandardTransient to be inheritable it must be 'object of RootObj'
instead of 'object'
Run
The way in which I have define this is:
type
Handle*[T] {.importcpp: "opencascade::handle<\'0>",
header: "Standard_Handle.hxx", bycopy, pure, inheritable.} =
object
[...]
type
StandardTransient* {.importcpp: "Standard_Transient",
header: "Standard_Transient.hxx", bycopy, pure,
inheritable.} = object
[...]
type
HandleStandardTransient* = Handle[StandardTransient]
Run
If I remove `pure,inheritable` from `StandardTransient`, it stops from
complaining on `NCollectionHandle`, but then it starts complaining on:
type
Graphic3dShaderProgram* {.importcpp: "Graphic3d_ShaderProgram",
header: "Graphic3d_ShaderProgram.hxx", bycopy.}
= object of StandardTransient
Run
because obviously `StandardTransient` stops being inheritable.
What would be the proper way to mark it as `inheritable`?
