And there are +additional examples in ../tools/designer/examples/ and in the +extensions subdirectories. The documentation contains two detailed Qt +tutorials and additional tutorials for Qt Designer. The examples here +are useful for learning particular Qt classes and techniques, but to +learn Qt itself we recommend starting with the documentation's short +"How to Learn Qt" document. + +It is best to run each example from its own directory since some of +them assume they are run from there. + + +aclock + This example displays an analog clock widget. + It shows how to create a custom widget (QWidget subclass) and how + to create a timer using QTimer. + +action + A single document interface application example with a menu bar, + tool bar and status bar that provides simple text editing. + It shows how to implement a typical modern application, how to + create a QMainWindow subclass, and how to create actions that can + be assigned to menus (QPopupMenu) and toolbars (QToolBar) using + QAction. It also shows how to print using QSimpleRichText. + +addressbook [obsolete] + +application [obsolete; see the action example instead] + +biff [Unix-specific] + Biff is a simple graphical program to indicate whether there is + new mail; it looks like xbiff but is much shorter. + +buttongroups + This examples shows different types of group boxes (QButtonGroup, + and QGroupBox), and different kinds of buttons (QCheckBox, + QRadioButton, and QPushButton). It also shows how to add a + QPopupMenu to a button. + +canvas + This examples demonstrates many of QCanvasView's facilities, but + by no means all of them. It uses QCanvasItem, QCanvasLine, + QCanvasRectangle, QCanvasEllipse, QCanvasSprite, and of course + QCanvas. + +chart + An application for maintaining simple numeric data and visualising + the data using pie and bar charts. + Tutorial #2 explains this application in detail. + +checklists + Shows two list views with check box and radio button items. (These + kinds of lists are often used with setup programs.) + Shows the use of QListView, QListViewItem, QCheckListItem, + QListViewItemIterator, and QValueList. + +cursor + This example shows how to set the mouse cursor for a widget. Shows + Qt's cursors and a custom cursor using QLabel and QCursor. + +customlayout + This examples demonstrates how to write a customized layout + (geometry) manager, like a Card-Layout, Border-Layout and + Flow-Layout. + +dclock + This example displays a digital LCD clock and can switch between + time and date. + It uses the QLCDNumber widget and a couple of QTimers. + +demo + Run this to see almost all of Qt's widgets in action, including + drag and drop, 2D graphics, etc. + +desktop + The desktop demo contains three routines, each of which draws + something on the desktop. It does some nice stuff with QPainter, + and also demonstrates how one can treat the desktop as a widget + like any other. + +directpainter [Qt/Embedded-specific] + Shows the use of QDirectPainter. + +dirview + This example program demonstrates how to use a QListView and + QListViewItems to build a multi-column hierarchical, memory- and + CPU-efficient directory browser. It also demonstrates how to use + Drag'n'Drop in a QListview. (See also the fileiconview example.) + +distributor + This is a utility program that can be used to modify the paths + used in the Qt library binary to make the binary suitable for + distribution. For experts only. + +dragdrop + Demonstrates image and text drag and drop. + +drawdemo + Draws a color wheel, text and shapes. This example demonstrates + several drawing functions and printer output using QPainter, + QWMatrix, QFont, QFontMetrics, QColor, QBrush, and QPrinter. You + can easily add you own drawing functions. See "ourDrawFunctions". + +drawlines + This example shows very simple mouse-based user interaction and + painting without any world transform matrix or other advanced + features. Run the program, click the button, move the mouse, + release the button, and watch the lines get drawn. + +extension + An extension dialog with simple and advanced appearances + controlled by a toggle button. + +fileiconview + This example partially implements a very basic file manager using + a widget derived from QIconView to display the current directory. + It uses the DirectoryView widget from the dirview example to + display the directory tree. + It also shows how to add a QComboBox to a QToolBar and how to + implement a context menu using QPopupMenu. + +fonts [obsolete; see the qfd example instead] + +forever + WARNING: this program has a strobe effect. + See how fast Qt can draw colored rectangles. This example + continuously draws rectangles in a window and has another widget + that counts the number of rectangles that are drawn per second. + +gridview + A QGridView with 100x100 cells. + +hello + Hello world with colored animated wavy text. + +helpdemo + Shows how to use Qt Assistant as an application's online help + tool. (See also the helpsystem example.) + +helpsystem + This example shows how to implement context-sensitive help in + various ways in a Qt application using QToolTip, QWhatsThis, and + QAssistantClient to control Qt Assistant. + +helpviewer + The HelpViewer example implements a simple HTML help browser using + Qt's richtext capabilities. + +i18n + This example shows how to internationalize applications. Start it with + ./i18n en + to run the application in English, and with + ./i18n de + to run it in German. Other languages are also available including, + Arabic (ar), French (fr), Italian (it), Japanese (jp), Korean + (ko), Norwegian (no), and Russian (ru). Some languages depend on + the availability of suitable fonts. + +iconview + This example implements a flexible icon view which can store lots + of icon items. It supports Drag'n'Drop and different selection + modes using QIconView. + +kiosk [Qt/Embedded-specific] + An MPEG player. + +launcher [Qt/Embedded-specific] + A program launcher. + +layout [obsolete] + This example shows simple and intermediate use of Qt's layout + classes, QGridLaout, QBoxLayout etc. + +life + An implementation of the life game with a Unix-flavor GUI. + +lineedits + This example shows how to use various properties of QLineEdit + including echo modes, input masks, and validators. + +listbox + Shows QListBox options. + +listboxcombo + This example shows how to use QListBox (with single selection and + multi selection) and QComboBox (editable and non-editable). + +listviews + This examples shows how to work with QListView (a tree view + widget) + +mdi + Similar to the action example, but this time using MDI (Multiple + Document Interface). It subclasses QMainWindow and uses the + QWorkspace class to provide MDI and shows how to implement an MDI + Window menu. + +menu + This example demonstrates the simple use of menus (a menu bar and + pull-down menus), and a context menu. (See also the popup + example.) + +movies + The Movies example displays animated GIF files using the QMovie + and QLabel classes. + +network/archivesearch + Shows how to use QHttp to request and receive data from a web + site. + +network/clientserver + Provides a client application and a server application that + communicate using QSocket and QServerSocket. + +network/ftpclient + A simple FTP client that uses QFtp to retrieve directory listings + and to download and upload files. + +network/httpd + An extremely simple HTTP daemon built using QServerSocket. + +network/infoprotocol + A more complex client/server example. + +network/mail + A simple mail client that can send email using the QSocket class. + +network/networkprotocol + A simple implementation of a subset of the NNTP protocol.

Two types of progress dialog + are offered, one that simply shows text, and a custom one that + shows an animation using a QLabel and a QTimer. + +progressbar + Shows how to use a QProgressBar. + +qdir + Shows how to use and customize QFileDialog. Run + qdir --help + for details. Also shows QFileInfo. + +qfd + This example program displays all the characters of a selected + font. It shows the use of QFontDialog, QFontMetrics and QFontInfo, + and a QTable subclass. + +qmag + This is a simple magnifier-type program.

You can draw + with different pen colors and widths and save the result as a + pixmap in various formats. It shows how to do drawing using a + QWidget subclass (rather than a QCanvas for example). It also + shows how to add a QSpinBox to a QToolBar and how to implement a + button that pops up a menu (using QPushButton and QPopupMenu), and + also how to use the QColorDialog. + +scrollview + This example shows one way of using a QScrollview.
