[vtkusers] newbie Q about widgets and WidgetsCxxTests

[kdsfinger at gmail.com]

hi, all

I have some questions about how to use the widgets (e.g.
vtkImagePlaneWidget) provided in VTK/Widgets. I am going to use them
in C++ program so the tcl and python is not considered. My questions
are:
1. Is the vtkImagePlaneWidget a "standard" class of vtk? As I checked
the doxygen file produced based on the VTK-binary, I can't find such a
class. (I have the vtkImagePlaneWidget.o in
VTK-binaryWidgets/CMakeFiles/vtkWidgets.dir and
vtkImagePlaneWidgetTcl.cxx in VTK-binary/Widgets) I also have the
WidgetsCxxTests in VTK-binary/bin. I don't have vtkImagePlaneWidget.h
and vtkImagePlaneWidget.cxx anywhere in VTK-binary. How can I know
what functions can be used with the vtkImagePlaneWidget and how to use
it in C++ program?
2. When I try to run the WidgetsCxxTests in VTK-binary/bin, it takes
arguments from the command line. Is there any hint what the arguments
are? (I guess it taks the name of the widget I want to test, but did
not work).
3. Should I produce doxygen docs based on VTK (the sorce) or
VTK-binary? I believe some of the source is not included in VTK-binary
based on the parameters set when run ccmake. If the doc is generated
based on the VTK, then some of the classes may no available in
VTK-binary.
Thanks ahead for your help.
