Python – PyQt5 QWidget sets the fixed width to the smallest available size

I

have a layout where I add a bunch of widgets (now QPushButton, but it can be any QWidget element) that by default fill the entire width when added. Since my custom sizing handles use this width to move elements, they register each element as the same size as the layout, which causes my function to move them even though they get smaller after I resize.

So, when I add a widget, is there a way to shrink it to the minimum size to accommodate the content? Stuff along the line:

item = QPushButton("somestuff") # | QLabel | QWidget | etc
item.setFixedWidth(item.contents.size().width())

To calculate the minimum width, you can use QFontMetrics

item = QPushButton("somestuff") # | QLabel | QWidget | etc
fm = QFontMetrics(item.font())
item.setFixedWidth(fm.width(item.text()))
