From 6b8e866391cf933f077756c8ad154683885ea07f Mon Sep 17 00:00:00 2001 From: Sze Howe Koh Date: Sat, 2 Nov 2013 10:13:45 +0800 Subject: Doc: Clean up threading examples MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Example 3 (Clock) is a collection of anti-patterns. - It implements a slot in a QThread subclass and then forces the new thread to use Qt::DirectConnection to invoke the slot in the "wrong" thread. - It talks about getting away with non-thread-safe usage - It uses a thread as a timer and then admits that it's an over- complicated approach. - Example 4 (Permanent Thread) is over-complicated yet incomplete. A better one exists in the QThread class ref. - Example 1 (Thread Pool) is covered by the QThreadPool class ref. - Example 2 (QtConcurrent::run()) is covered in the "Threading and Concurrent Programming Examples" page and the "QtConcurrentRun" page. - The undocumented "Hello Thread" example is covered in the QThread class ref. - These examples cannot be accessed from Qt Creator's Examples tool. - These examples are neither widget-related nor tutorials, contrary to their source paths.
