.SH DESCRIPTION
Encapsulates common Look and Feel of a GUI.
.PP
While it is not possible to fully enumerate the look of graphic elements and the feel of widgets in a GUI, a large number of elements are common to many widgets. The QStyle class allows the look of these elements to be modified across all widgets that use the QStyle methods. It also provides two feel options - Motif and Windows.
.PP
In previous versions of Qt, the look and feel option for widgets was specified by a single value - the GUIStyle. Starting with Qt 2.0, this notion has been expanded to allow the look to be specified by virtual drawing functions.
.PP
Derived classes may override some or all of the drawing functions to modify the look of all widgets which utilize those functions.
.PP
Examples:

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QStyle::~QStyle () \fC[virtual]\fR"
Destructs the style.
.SH "QRect QStyle::buttonRect ( int x, int y, int w, int h ) \fC[virtual]\fR"
Returns the rectangle available for contents in a push button. Usually this is the entire rectangle but it may also be smaller when you think about rounded buttons.
