# Qt widgets for CSXCAD structures (tree, property and grid editors, VTK 3D view): the library behind AppCSXCAD.
# Third of the four openEMS packages. Built with Qt6 because the project's VTK 9.7 is; upstream's CMake takes
# the Qt version from VTK_QT_VERSION and links Qt6::Core5Compat for its QRegExp use.

# Pin the exact VTK ABI this package was built against. VTK freezes its soname at
# libvtk*.so.1 across all of 9.x, so rpm cannot tell 9.5 from 9.6 from 9.7: a consumer
# built against one installs cleanly against another and fails at LOAD with undefined
# symbols. %%vtk_abi comes from vtk-devel's macros.vtk; the %%build test catches a
# buildroot without it (see 3dslicer-igt.spec for why the check is not at parse time).
Requires:       vtk(abi) = %{?vtk_abi}%{!?vtk_abi:UNSET}

%description
QCSXCAD provides Qt widgets to display and edit CSXCAD structures: the
primitive/property tree, property and grid editors, a VTK-based 3D view with
mesh and field overlays, and X3D/POV-Ray export. AppCSXCAD is its viewer
application; openEMS scripts call it to inspect a model before solving.

%changelog
* Fri Oct 30 2026 Morgan Hough <morgan.hough@gmail.com> - 0.7.0-2
- Rebuild against Fedora's vtk 9.7.0 on rawhide. No spec change was needed: the
  mock build was clean and no binary needs libjava, libjvm or libvtkJava.

* Fri Oct 23 2026 Morgan Hough <morgan.hough@gmail.com> - 0.7.0-1
- Initial package: QCSXCAD 0.7.0 on Qt6 (Core5Compat) and the project's VTK 9.7 (vtk(abi) pin).
