A widget that is not embedded in a parent widget is called a + \l{Application Windows and Dialogs}{window}. + + \image parent-child-widgets.png A parent widget containing various child widgets. + + The QWidget class provides the basic capability to render to the screen, and to + handle user input events. All UI elements that Qt provides are either subclasses + of QWidget, or are used in connection with a QWidget subclass. Creating custom + widgets is done by subclassing QWidget or a suitable subclass and reimplementing + the virtual event handlers. + + \section1 Layouts + + \l{Layout Management}{Layouts} are an elegant and flexible way to automatically + arrange child widgets within their container. Each widget reports its size requirements + to the layout through the \l{QWidget::}{sizeHint} and \l{QWidget::}{sizePolicy} + properties, and the layout distributes the available space accordingly. + + \table + \row + \o \image qgridlayout-with-5-children.png + \o \image qformlayout-with-6-children.png + \endtable + + \l{Qt Designer Manual}{\QD} is a powerful tool for interactively creating and + arranging widgets in layouts. + + \section1 Widget Styles + + \l{Implementing Styles and Style Aware Widgets}{Styles} draw on behalf of widgets + and encapsulate the look and feel of a GUI. Qt's built-in widgets use the QStyle + class to perform nearly all of their drawing, ensuring that they look exactly like + the equivalent native widgets. + + \table + \row + \o \image windowsxp-tabwidget.png + \o \image plastique-tabwidget.png + \o \image macintosh-tabwidget.png + \endtable + + \l{Qt Style Sheets} are a powerful mechanism that allows you to customize the + appearance of widgets, in addition to what is already possible by subclassing QStyle. +*/ + +/*! + \page widget-classes.html + \title Widget Classes + + \contentspage Widgets and Layouts + \nextpage Layout Management + + Below you find a list of all widget classes in Qt.
