As part of the development for the forthcoming application Beaver, prototypes were made to investigate the best ways to handle things like gui design, internationalization, charting integration and so on.
These (deliberately simple) examples will be made available here in case someone else can find them useful.
Not a tutorial, but putting this here in case I need to refer back in future. Basically, a graphical user interface(GUI) Qt application needs to update/redraw itself...doing so every second can be a resource hogging process.
This short guide, called "Utiliser Py Qt4 avec Qt Designer" is made available online in pdf format (recommended) or in dark html, both including short code samples.
One of those described workflows goes like this: The example used is a very simple gui using layouts, with an edit box and a button which adds this entry to a list widget.
