Class e.p.p.w.s.Square(Widget):

Part of elisa.plugins.pigment.widgets.size_enforcer View In Hierarchy

Widget that is constrained to be square, that is having an aspect ratio of 1:1. One can change its size as usual by setting its width or height. It will automatically resize itself to stay visually square.

Be careful, if the square is part of a group then its properties width and height might not be equal but still it will render visually square because these values are relative to the parent group.

When both width and height are changed at the same time the height has priority over the width.
