DESCRIPTION

A large number of GUI 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 functions. It also provides two feel options: Motif and Windows.

Although it is not possible to fully enumerate the look of graphical elements and the feel of widgets in a GUI, QStyle provides a considerable amount of control and customisability.

In Qt 1.x the look and feel option for widgets was specified by a single value: the GUIStyle. Starting with Qt 2.0, this notion was expanded to allow the look to be specified by virtual drawing functions.

Derived classes may reimplement some or all of the drawing functions to modify the look of all widgets that use those functions.

Languages written from right to left (such as Arabic and Hebrew) usually also mirror the whole layout of widgets. If you design a style, you should take special care when drawing asymmetric elements to make sure that they also look correct in a mirrored layout. You can start your application with -reverse to check the mirrored layout. Also notice, that for a reversed layout, the light usually comes from top right instead of top left.

The actual reverse layout is performed automatically when possible. However, for the sake of flexibility, the translation cannot be performed everywhere. The documentation for each function in the QStyle API states whether the function expects/returns logical or screen coordinates. Using logical coordinates (in ComplexControls, for example) provides great flexibility in controlling the look of a widget. Use visualRect() when necessary to translate logical coordinates into screen coordinates for drawing.

In Qt versions prior to 3.0, if you wanted a low level route into changing the appearance of a widget, you would reimplement polish(). With the new 3.0 style engine the recommended approach is to reimplement the draw functions, for example drawItem(), drawPrimitive(), drawControl(), drawControlMask(), drawComplexControl() and drawComplexControlMask(). Each of these functions is called with a range of parameters that provide information that you can use to determine how to draw them, e.g. style flags, rectangle, color group, etc.

For information on changing elements of an existing style or creating your own style see the Style overview.

Styles can also be created as plugins.

The rect r should be in logical coordinates. Reimplementations of this function should use visualRect() to change the logical coordinates into screen coordinates when using drawPrimitive() and drawControl().

The how argument is used to control how the ComplexControl is drawn. Multiple flags can OR'ed together. See the table below for an explanation of which flags are used with the various ComplexControls.

The widget argument is a pointer to a QWidget or one of its subclasses. The widget can be cast to the appropriate type based on the value of control. The opt argument can be used to pass extra information required when drawing the ComplexControl.

Style_Down Set if the toolbutton is down (i.e., a mouse button or the space is pressed). Style_On Set if the toolbutton is a toggle button and is toggled on. Style_AutoRaise Set if the toolbutton has auto-raise enabled. Style_MouseOver Set if the mouse pointer is over the toolbutton. Style_Raised

void QStyle::drawControlMask ( ControlElement element, QPainter * p, const QWidget * widget, const QRect & r, const QStyleOption & opt = QStyleOption::Default ) const [pure virtual]

The rect r should be in screen coordinates.

void QStyle::drawItem ( QPainter * p, const QRect & r, int flags, const QColorGroup & g, bool enabled, const QPixmap * pixmap, const QString & text, int len = -1, const QColor * penColor = 0 ) const [virtual]

By default, if both the text and the pixmap are not null, the pixmap is drawn and the text is ignored.  

void QStyle::drawPrimitive ( PrimitiveElement pe, QPainter * p, const QRect & r, const QColorGroup & cg, SFlags flags = Style_Default, const QStyleOption & opt = QStyleOption::Default ) const [pure virtual]

The rect r should be in screen coordinates.

The flags argument is used to control how the PrimitiveElement is drawn. Multiple flags can be OR'ed together.

For example, a pressed button would be drawn with the flags Style_Enabled and Style_Down.

The opt argument can be used to control how various PrimitiveElements are drawn. Note that opt may be the default value even for PrimitiveElements that make use of extra options. When opt is non-default, it is used as follows:
