pyqt5 layout

[Nickd12]

for anyone that knows about pyqt5 how can i set my BuildDateTime class in a box to group it together then place it in the Qmainwindow the window class to as a group that way if i wanted to move the class as a whole i would be able to for example once i put date and time in the class i can just put them in a box and move the boxes position and not the elements themselves
