ShowEventDriver
VTKExamples/Cxx/Qt/ShowEventDriver
Description¶
Small example (not doing anything actually) to show the use of the overwritten QWidget::showEvent() function to initialize the VTK widget when it is actually used, not directly in the constructor.
Code¶
ShowEventDriver.cxx
#include <QApplication> #include "ShowEvent.h" int main(int argc, char *argv[]) { QApplication app(argc, argv); ShowEvent showEvent; showEvent.show(); return app.exec(); }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(ShowEventDriver) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(ShowEventDriver MACOSX_BUNDLE ShowEventDriver.cxx) target_link_libraries(ShowEventDriver ${VTK_LIBRARIES})
Download and Build ShowEventDriver¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
Click here to download ShowEventDriver and its CMakeLists.txt file. Once the tarball ShowEventDriver.tar has been downloaded and extracted,
cd ShowEventDriver/build
If VTK is 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 ..
Build the project:
make
and run it:
./ShowEventDriver
WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
