New-style Signal and Slot Support¶ This section describes the new style of connecting signals and slots introduced in PyQt4 v4.5.

How Qt Signals and Slots Work - Woboq Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood.
