Qt widget

[Rui]

I've worked with Java Swing several times and there I can create JPanel's to be later included in my application as a normal component. The concept of widget in Qt means something like a JPanel? If so, can that be made graphically or only through code? If not, if there any similar approach like JPanel's and so on or other usual/correct way to do it in Qt?

take a look at Qt Designer.
