public class QCommonStyle
The QCommonStyle class encapsulates the common Look and Feel of a GUI.
This abstract class implements some of the widget's look and feel that is common to all GUI styles provided and shipped as part of Qt.
Since QCommonStyle inherits QStyle, all of its functions are fully documented in the QStyle documentation.

protected QIcon standardIconImplementation(QStyle.StandardPixmap standardIcon, QStyleOption opt, QWidget widget)
standardIconImplementation
in class QStyle
public void drawComplexControl(QStyle.ComplexControl cc, QStyleOptionComplex opt, QPainter p, QWidget w)
Draws the given cc using the provided p with the style options specified by opt.
The w argument is optional and can be used as aid in drawing the control.
The opt parameter is a pointer to a QStyleOptionComplex object that can be cast to the correct subclass using the qstyleoption_cast() function. Note that the rect member of the specified opt must be in logical coordinates. Reimplementations of this function should use visualRect to change the logical coordinates into screen coordinates before calling the drawPrimitive or drawControl function.
The table below is listing the complex control elements and their associated style option subclass. The style options contain all the parameters required to draw the controls, including QStyleOption::state which holds the style flags that are used when drawing. The table also describes which flags that are set when casting the given opt to the appropriate subclass.

drawPrimitive
in class QStyle
public QPixmap generatedIconPixmap(QIcon.Mode iconMode, QPixmap pixmap, QStyleOption opt)
This function is reimplemented for internal reasons.
generatedIconPixmap
in class QStyle
public int hitTestComplexControl(QStyle.ComplexControl cc, QStyleOptionComplex opt, QPoint pt, QWidget w)
Returns the sub control at the given pt in the given complex cc (with the style options specified by opt).
Note that the pt is expressed in screen coordinates.
The opt argument is a pointer to a QStyleOptionComplex object (or one of its subclasses). The object can be cast to the appropriate type using the qstyleoption_cast() function. See drawComplexControl for details. The w argument is optional and can contain additional information for the function.
hitTestComplexControl
in class QStyle
public int pixelMetric(QStyle.PixelMetric m, QStyleOption opt, QWidget widget)
Returns the value of the given pixel m.
The specified opt and widget can be used for calculating the metric. In general, the widget argument is not used. The opt can be cast to the appropriate type using the qstyleoption_cast() function. Note that the opt may be zero even for PixelMetrics that can make use of it. See the table below for the appropriate opt casts:
Some pixel metrics are called from widgets and some are only called internally by the style. If the metric is not called by a widget, it is the discretion of the style author to make use of it. For some styles, this may not be appropriate.
pixelMetric
in class QStyle
public QSize sizeFromContents(QStyle.ContentsType ct, QStyleOption opt, QSize contentsSize, QWidget widget)
Returns the size of the element described by the specified opt and ct, based on the provided contentsSize.
The opt argument is a pointer to a QStyleOption or one of its subclasses. The opt can be cast to the appropriate type using the qstyleoption_cast() function. The widget is an optional argument and can contain extra information used for calculating the size.
See the table below for the appropriate opt casts:
sizeFromContents
in class QStyle
public int styleHint(QStyle.StyleHint sh, QStyleOption opt, QWidget w, QStyleHintReturn shret)
Returns an integer representing the specified style sh for the given w described by the provided style opt.
Note that currently, the shret and w parameters are not used; they are provided for future enhancement. In addition, the opt parameter is used only in case of the SH_ComboBox_Popup, SH_ComboBox_LayoutDirection, and SH_GroupBox_TextLabelColor style hints.
