[Insight-users] How to update an exeption to a GUI?

[Luis Ibanez]

Hi Joris,

ITK exceptions are more than simple strings, they can not
be directly assigned to a string.

However they provide the following methods

   1)  const char * GetDescription()
   2)  const char * GetLocation()
   3)  const char * what()
   4)  unsigned int GetLine()
   5)  const char * GetFile()

http://www.itk.org/Insight/Doxygen/html/classitk_1_1ExceptionObject.html

Use them at your discretion in order to compose
a message that you can display in your GUI.


Regards,


   Luis
