Just fin­ished speak­ing about PyQt pro­gram­ming in Lati­noWare.

It went ok, but I ran out of time, so no Q&A, and I could­n't show about 20% of the code. :-(

Any­way, here is the code in its dif­fer­ent stages, so you can see the "evo­lu­tion" of a sim­ple PyQt ap­p. I will prob­a­bly turn it in­to a re­al tu­to­ri­al in a few days and post it.

Here is the guide I was us­ing for my­self when do­ing the pre­sen­ta­tion:

1. 1. App back­­­end (1/­­to­­­do.py)

   2. Ba­sic win­­­dow with a treewid­get Col­umns Task/­­­Date/­­­Tags

   3. Com­pile archi­­­vo .ui, show how it works

   4. Tem­­­plate for main.py

2. 1. Load back­­­end da­­­ta in the task list

   2. Show in­­­ter­ac­­­tion is bro­ken

3. 1. Ex­­­plain sig­­­nal­s/s­lots

   2. Show dif­fer­­­ence be­tween 1/­­­main.py 2/­­­main.py

   3. Ex­­­plain au­­­to­­­con­nec­t, show on_lis­­­ta_item­Changed

   4. Show task per­­­sis­­­tence work­ing

4. 1. Fix tree dec­o­ra­­­tions

   2. Make items ed­itable

   3. Ex­­­plain changes in on_lis­­­ta_item­Changed

   4. Ex­­­plain the prob­lem with ed­it­ing date and tags in­­­­­line

   5. New idea: use a di­a­log to ed­it tasks (ed­i­­­tor.ui)

   6. Ex­­­plain lay­out man­agers

5. 1. Show changes in main.py

6. 1. Ac­­­tions

   2. Show ac­­­tions in de­sign­er

   3. Show ac­­­tions in main.py

7. 1. Tray

   2. Show tray class in main.py

   3. Show tray be­hav­iour

   4. Show dif­fer­­­ences in main.py
