[Insight-users] Required QT Version For Building QT-Dependent Examples In InsightApplications?

[Luis Ibanez]

Hi Constantine,

Thanks a lot for trying the code and for reporting back.

Yes, It doesn't seem that we have the coloring working right yet.

I guess I need to look closer at the proper way of changing color
buttons in Qt4.


The fact that it crashes in Release, is usually an indication
that we are dealing with uninitialized variables... I'll run it
with Valgrind to see if something obvious shows up.


BTW, For any Qt4 gurus out there,....

  If you can advice on the proper way of implementing
  button color changes in Qt4, that will be very much
  appreciated.


Thanks

     Luis
