Button resizing automatically

Question

I am using PyQt5 and I am trying to prevent push button from resizing automatically. So I used this code to achieve this. My goal was if I create a button with fixed size, it won't resize on its own. So I wrote the following code:

rect = QtCore.QRect()
rect.setSize(QtCore.QSize(5, 80))
button.setGeometry(rect)

But it doesn't work. The same resize issue is still there. What is going wrong there?

Answer 1

If you want a widget to maintain its size then you must use setFixedSize()

button.setFixedSize(QtCore.QSize(5, 80))

---

If your button is in a layout it will use the sizePolicy to determine the size behavior, in the case of the button it is:

• horizontal: QtWidgets.QSizePolicy.Minimum, which makes the widget take all the available width.
• vertical: QtWidgets.QSizePolicy.Fixed, that causes the widget to use the height defined by sizeHint() that depends on the content (text, font size, etc).

Therefore, the button is generally resized horizontally, and not vertically.
