i want to get to use the haptic device's button.

now i can control a object with Haptic device , here is the core code. referenced the example “ObjectController”

`auto server = std::make_shared();

auto client = server->makeDeviceClient(phantomOmni1Name);

auto controller = std::make_shared(object, client);

scene->addController(controller);

viewer->addChildThread(server);`

but when i want to get button's event. i read some source code about imstk like "imstkHapticDeviceManager.cpp" "imstkHapticeDeviceClient.cpp"

besides, i also read example code about HDAPI Graphics Examples, HDAPI Console Examples.

in my openion, i need to write HDcallback function to get the button event. like this

` HDCallbackCode HDCALLBACK CallbackFunction(void* pData){*******}

`

in main function

` hdStartScheduler();

hdScheduleAsynchronous(releaseHotFieldCallback, 0, HD_MAX_SCHEDULER_PRIORITY); `

here is the thing, if i want to run with out error, i need to initialize the haptic device whit this line code

HHD hHD = hdInitDevice(HD_DEFAULT_DEVICE);

but it's conflict with client code , Cannot exist together auto client = server->makeDeviceClient(phantomOmni1Name);

also i noticed that in "imstkHapticDeviceManager.cpp" there has function "initialize()" to initialize the client which called

"imstkHapticDeviceClient.cpp" m_handle = hdInitDevice(this->getDeviceName().c_str());

but when i add this line "server->initialize()" to my code, the application will crashed.

what should i do to solve this problem, thank for any adcice.
