Early Easter Eggs

Articles from Qt Quarterly - Tue, 23/07/2002 - 9:00pm
Qt has a very flexible and powerful event system. In this article, we will use it to hide an Easter egg in an application -- too late for this year's Easter, but early enough for next year.

Data Sharing with Class

Articles from Qt Quarterly - Tue, 23/07/2002 - 9:00pm
Data sharing, or copy on write, is used throughout Qt to combine the memory and speed efficiency of pointers with the ease of use of plain values. This article explains how to write your own data-shared classes. The two techniques underlying data sharing -- d-pointers and reference counting -- are useful in many other contexts, so read on!

Abusing QMap

The QMap<Key, Value> class stores (key, value) pairs where each key is associated with a single value. This article presents a quick-and-dirty trick to make keys work with multiple values.

Sorting QListViews

Articles from Qt Quarterly - Tue, 12/02/2002 - 12:00am
The QListView widget provides both list and tree views. The class provides locale-aware Unicode sorting by any column, or no sorting at all. There are often situations where the sorting required must be more sophisticated than straightforward lexical sorting. This article explains how to take precise control of QListView's sorting.

Seriously Weird QRegExp

Articles from Qt Quarterly - Tue, 12/02/2002 - 12:00am
C++ programmers can use Perl-style regular expressions with Qt 3.0's completely rewritten QRegExp class. We present some of the practicalities of using regular expressions for parsing, validation, and filtering. We also look at how to optimize regular expressions, and finish off with some weird trivia.
