Qt is equipped with a range of capable tool classes, from containers and iterators to classes for string handling and manipulation.
Other classes provide application infrastructure support, handling plugin loading and managing configuration files.
The Completer example shows how to provide string-completion facilities for an input widget based on data provided by a model.
The Custom Completer example shows how to provide string-completion facilities for an input widget based on data provided by a model. The completer pops up suggestions for possible words based on the first three characters input by the user and the user's choice of word is inserted into the TextEdit using QTextCursor.
This example shows how to create a Qt plugin.
The Internationalization (I18N) example demonstrates Qt's support for translated text. Developers can write the initial application text in one language, and translations can be provided later without any modifications to the code. It also demonstrates how to detect the system language settings and show the UI in the appropriate language.
Demonstrates how to extend Qt applications using plugins.
The QRegularExpression example shows how regular expressions in Qt are applied to text by providing an environment in which new regular expressions can be created and tested on custom text strings.
The Regular Expressions (RegExp) example shows how regular expressions in Qt are applied to text by providing an environment in which new regular expressions can be created and tested on custom text strings.
The Settings Editor example shows how Qt's standard settings support is used in an application by providing an editor that enables the user to view the settings for installed applications, and modify those that can be edited.
This example shows how to create a plugin that extends Qt with a new GUI look and feel.
The Tree Model Completer example shows how to provide completion facilities for a hierarchical model, using a period as the separator to access Child, GrandChild and GrandGrandChild level objects.
This example shows Qt's undo framework in action.
This example shows how to implement undo/redo functionality with the Qt undo framework.
