Download and Build EventQtSlotConnectDriver

Click here to download EventQtSlotConnectDriver and its CMakeLists.txt file. Once the tarball EventQtSlotConnectDriver.tar has been downloaded and extracted,

 cd EventQtSlotConnectDriver/build

This example requires Qt and VTK.

If VTK and Qt are installed:

 cmake ..

If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:

 cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

If Qt is not found on your system, you will need to tell CMake where to find qmake:

cmake -DQT_QMAKE_EXECUTABLE:FILEPATH=/usr/something/qmake  ..

Build the project:

make

and run it:

./EventQtSlotConnectDriver

WINDOWS USERS

Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time. You may also need to add a Qt related path.
