Here is a quick  tour of what you missed if you did not make it to my Guadec talk this year.

It was a bit different from my usual ‘state of the union’ or ‘GTK+ roadmap’ presentations. Instead, I showed a selection of tips and tricks, things you perhaps didn’t know yet how to do with GTK+.

Scrollbar steppers still exist

Context menus on scrollbars

Adding items to context menus and popovers

Decorative overlays

Custom spin buttons

Discrete scales

Markup in text views

Filter models with extra columns

The slides are here, and if you want to study the examples in more detail, they are all available in gtk3-demo in GTK+ master.
