How to access Qt components loaded from file?

[Juan Christian]

Thanks, it's working using QTimer. The thing is that whenever the program
is going to do something, in my case, draw a new QGroupBox with some
components inside and put it in the Form (I'm using VBoxLayout in the main
form) the program freezes, and I'm using very simple components just for
testing.This shouldn't be normal, right?

Am I doing something wrong?
