GI.Gtk.Declarative.Attributes.Collected

Internal helpers for applying attributes and signal handlers to GTK+ widgets.

Documentation

type CollectedProperties widget = HashMap Text (CollectedProperty widget)

A collected map of key/value pairs, where the type-level property names are represented as Text values. This is used to calculate differences in old and new property sets when patching.

data Collected widget event

All the collected properties and classes for a widget. These are based on the Attribute list in the declarative markup, but collected separately into more efficient data structures, optimized for patching.
