From 33743aeb2be37d166bcc3291a98dd22026871cef Mon Sep 17 00:00:00 2001 From: Cristian Maureira-Fredes Date: Fri, 5 Feb 2021 10:07:19 +0100 Subject: examples: directory structure When generating the gallery automatically, the structure of the examples was not the same for all the modules. This reorganization was made under the following assumption: An example requires: - its own directory, - a '.pyproject' file, - one or more '.py' files, - extra files (likes images, .rc, .ui, etc) Even for cases when subdirectories are made to depict categories, like 'widgets/state-machine/...', one directory is required per example. There should not be '.pyproject' files for categories, except for the general 'examples.pyproject' to open all of them.
