Label wrapped vertical size

[jamesdbrock]

This vertical size calculation is wrong if word_wrap=True.

pyedifice/edifice/base_components.py

Line 910 in 943bf85

self._set_size(size * len(str(self.props.text)), size, lambda size: (size * len(str(self.props.text)), size))

word_wrap=True size calculations seem to work okay if you don't set the "width" of Label directly, and instead set the "width" of its containing layout widget. (PySide6 v6.6.0)

“If you want the QLabel to fit the text then you must use adjustSize()”

“The use of rich text in a label widget can introduce some problems to the layout of its parent widget. Problems occur due to the way rich text is handled by Qt’s layout managers when the label is word wrapped.”

I've put C++ code at http://egret.psychol.cam.ac.uk/code/2017_01_16_qt_height_for_width/ for the following layouts:

• BoxLayoutHfw, VBoxLayoutHfw, HBoxLayoutHfw -- replacements for QBoxLayout etc.
• GridLayoutHfw -- replacements for QGridLayout.
• FlowLayoutHfw -- replacement for Qt's FlowLayout (http://doc.qt.io/qt-5/qtwidgets-layouts-flowlayout-example.html).
