[vtkusers] Compile QT 4.4.

[Dongqing Chen]

Hi, Eric:

  Thanks for your instruction. 

  1). I downloaded and installed Qt 4.4.3 and VTK 5.2 on my computer. As before, I compiled VTK 5.2 using CMake2.4 and bulit using VC++ 6 sucessfully with with BUILD_EXAMPLES: ON and VTK_USE_INFOVIS: ON.

 2). After installing the Qt 4.4.3, I run the configure command under Qt folder.

 3). When I complied Qt 4.4.3 with VTK 5.2 using CMake 2.4 with VTK_USE_GUISUPPORT: ON and VTK_USE_QVTK: ON. Unfortunately, an error appeared and  the CMake could not find the desired Qt 4.4, which I specified in CMake. Please see the attached screen snapshot. 

4). Some patches of the CMakelists are listed as follows.

**********************************************************************************************************
 INCLUDE( ${CMAKE_ROOT}/Modules/FindQt${DESIRED_QT_VERSION}.cmake )

IF(NOT QT_FOUND)
  MESSAGE("Qt was not found")
ELSE(NOT QT_FOUND)
**********************************************************************************************************

Also the entire CMakelist.txt is attached. 

 Since it is my first time to compile QT, please forgive me for any ignorance. 

Best Wishes,

  Hello Dongqing, 


  I can't answer number 1, but as to number 2: There are two examples I have found especially helpful in compiling Qt along with VTK -- VTK/Examples/GUI/Qt/SimpleView and VTK/Examples/Infovis/Cxx/EasyView. Both of them have CMakeList.txt files which should help you get started using CMake to compile your project which includes both Qt and VTK. 


  You can try these applications out by compiling VTK with BUILD_EXAMPLES: ON and VTK_USE_INFOVIS: ON. To build the QVTKWidget, which can be used along with Qt Designer, build VTK with VTK_USE_GUISUPPORT: ON and VTK_USE_QVTK: ON.


  I know this doesn't give too many details, but I hope it helps get you started,
  -Eric
