java equivalent panels in qt

Question

I would like to know the Java panel equivalent in QT. I mean which class do we need to use in QT, i.e. qframe or qwidget. I need to add many panels to my QT mainwindow.

Answer 1

QFrame, QScrollArea, etc. have properties that handle panel appearance and are suitable for component containers and form layout.

QWidget has no frameShape(), frameShadow(), or lineWidth(), but it has layout and size operation methods, so it can also be used as a panel if you do not need borders, scroll, docking or other additional behavior.
