[ITK Community] [Insight-users] registration using Mutual Information

[Luis Ibanez]

Hi Massi,

This error message:

*QWidget: Must construct a QApplication before a QPaintDevice*

seems to be more closely related to Qt than to ITK.

You may want to modularize your application, to separate the
ITK image analysis from the Qt GUI, and in this way, make
easier to debug the combined application.


    Regards,

        Luis
