Here are a few of the issues that I have had with migrating a few plugins from
ParaView 3.10 to 3.12:
I now use EXTRA_EXTERNAL_PLUGIN_DIRS instead of EXTERNAL_MODULES.
Where I used to have code in my cmake files such as:
# -- Add the Server Manager XML
PARAVIEW_INCLUDE_SERVERMANAGER_RESOURCES( "${H5Vtk_SM_XML}" )
# -- Add the Client side xml
PARAVIEW_INCLUDE_GUI_RESOURCES( "${H5Vtk_Client_XML}" )
# -- Add the wrapped sources
PARAVIEW_INCLUDE_WRAPPED_SOURCES("${H5Vtk_SM_Wrapped_SRCS}")
# -- Add additional sources that are NOT wrapped
PARAVIEW_INCLUDE_SOURCES ("${H5Vtk_SRCS}")
I now have this code:
ADD_PARAVIEW_PLUGIN ("PVH5VtkPlugin" "1.0"
SERVER_MANAGER_SOURCES ${H5Vtk_Server_Wrapped_Sources}
SERVER_MANAGER_XML ${H5Vtk_SM_XML}
SERVER_SOURCES ${H5Vtk_Server_Sources}
GUI_RESOURCE_FILES ${H5Vtk_Client_XML}
REQUIRED_ON_SERVER )
I also have some Custom object panels I designed with QDesigner and I have
found I need to add the following to the constructor:
QMetaObject::connectSlotsByName(this);
in order to get the auto connect of signals/slots connected properly. After
those changes the plugins now seem to be working correctly.
The other comment I have is that the original CMake code I had to add a server
side "plugin" really just added additional code to one of the PVFilters targets
and then I compiled a separate plugin that had the gui code. The first
iteration of changes had me creating actual plugins for both the server and
client side which seemed even more confusing. After looking through some
additional plugins in the ParaView source directory I was able to extract the
needed cmake logic to compile the plugin with our without the GUI stuff
included based on if ParaView was being compile with Qt support. I think this
is the "preferred" way to do this now. If not, can someone with knowledge
please comment.
Hope that helps someone in the future.
