- \title An Overview of Qt's Examples
- \brief A short guide to the different categories of examples included with Qt.
- \ingroup howto
-
- Qt is supplied with a variety of examples that cover almost every aspect
- of development. These examples are ordered by functional area, but many
- examples often use features from many parts of Qt to highlight one area
- in particular.
-
- This document provides a brief overview of each example category and
- provides links to the more formal \l{Qt Examples}{list of examples}.
-
- \section1 \l{Qt Examples#Widgets}{Widgets}
-
- \l{Qt Examples#Widgets}{\inlineimage widget-examples.png
- }
-
- Qt comes with a large range of standard widgets that users of modern
- applications have come to expect.
-
- You can also develop your own custom widgets and controls, and use them
- alongside standard widgets.
-
- It is even possible to provide custom styles and themes for widgets that can
- be used to change the appearance of standard widgets and appropriately
- written custom widgets.
-
- \section1 \l{Qt Examples#Dialogs}{Dialogs}
-
- \l{Qt Examples#Dialogs}{\inlineimage dialog-examples.png
- }
-
- Qt includes standard dialogs for many common operations, such as file
- selection, printing, and color selection.
-
- Custom dialogs can also be created for specialized modal or modeless
- interactions with users.
-
- \section1 \l{Qt Examples#Main Windows}{Main Windows}
-
- \l{Qt Examples#Main Windows}{\inlineimage mainwindow-examples.png
- }
-
- All the standard features of application main windows are provided by Qt.
-
- Main windows can have pull down menus, tool bars, and dock windows. These
- separate forms of user input are unified in an integrated action system that
- also supports keyboard shortcuts and accelerator keys in menu items.
-
- \section1 \l{Qt Examples#Layouts}{Layouts}
-
- \l{Qt Examples#Layouts}{\inlineimage layout-examples.png
- }
-
- Qt uses a layout-based approach to widget management. Widgets are arranged in
- the optimal positions in windows based on simple layout rules, leading to a
- consistent look and feel.
-
- Custom layouts can be used to provide more control over the positions and
- sizes of child widgets.
-
- \section1 \l{Qt Examples#Painting}{Painting}
-
- \l{Qt Examples#Painting}{\inlineimage painting-examples.png
- }
-
- Qt's painting system is able to render vector graphics, images, and outline
- font-based text with sub-pixel accuracy accuracy using anti-aliasing to
- improve rendering quality.
-
- These examples show the most common techniques that are used when painting
- with Qt, from basic concepts such as drawing simple primitives to the use of
- transformations.
-
- \section1 \l{Qt Examples#Item Views}{Item Views}
-
- \l{Qt Examples#Item Views}{\inlineimage itemview-examples.png
- }
-
- Item views are widgets that typically display data sets. Qt 4's model/view
- framework lets you handle large data sets by separating the underlying data
- from the way it is represented to the user, and provides support for
- customized rendering through the use of delegates.
-
- \section1 \l{Qt Examples#Graphics View}{Graphics View}

- custom XML format.
-
- \section1 \l{Qt Examples#Tools}{Tools}
-
- \l{Qt Examples#Tools}{\inlineimage tool-examples.png
- }

- most appropriate formats.
-
- Drag and drop can also be implemented for internal use by applications.
-
- \section1 \l{Qt Examples#Threads}{Threads}
-
- \l{Qt Examples#Threads}{\inlineimage thread-examples.png
- }
-
- Qt 4 makes it easier than ever to write multithreaded applications. More
- classes have been made usable from non-GUI threads, and the signals and slots
- mechanism can now be used to communicate between threads.
-
- Additionally, it is now possible to move objects between threads.
