[IGSTK-Users] A question about igstkEventTransductionMarco

[Vincent Gratsac]

Hi igstk-users,

There is two points I would like to discuss :

First, I have some problems with QTWidget and ViewNew available in IGSTK 
Sandbox.
I'm not able to display objects in these views, and I did not find 
example code which is working fine.
Could anyone tell me how to use these classes or show me a sample code ?

Second, I tried to use the igstkEventTransductionMacro and it seems that 
there is actually a bug. ProcessInputs() method is not called.
As Luis Ibanez adviced me, I added a call to this method in the macro, 
and now the problem is solved. So I think it would be nice to add this 
new line in each event transduction macro.

Vincent
