About a year ago, Josh Berkus was reviewing some Bricolage SQL code, looking to optimize it for PostgreSQL. One of the things he noticed was that we were fetching a lot more rows for an object than we needed to. The reason for this is that an object might be associated with one or more groups, and to get back a list of all of the group IDs, we were getting multiple rows. For example, if I wanted to fetch a single story with the ID 10, I might get back rows like this: SELECT s.id, s.title, grp.id FROM story s, member m, grp g WHERE s.id = m.story_id AND m.grp_id = g.id AND s.id = 10; s.id | s.title | grp.id -----+---------------------+-------- 10 | The Princess Bride | 23 10 | The Princess Bride | 24 10 | The Princess Bride | 25 10 | The Princess Bride | 26 10 | The Princess Bride | 27 Just a Theory

wxGlade: a GUI builder for wxWidgets/wxPython NOTE: This version of the tutorial is in sync with the current wxGlade on CVS, so some parts of it might not apply to the latest release. wxGlade Tutorial The aim of this minimal tutorial is to give an overview of wxGlade and its functionalities: despite its very short length, it is (hopefully) complete enough to make you understand how the application works, through a step-by-step description of the creation of a frame containing a notebook with some controls, a menubar and a statusbar.
