The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.
\inmodule QtWidgets
Qt contains a set of QStyle subclasses that emulate the styles of the different platforms supported by Qt (QWindowsStyle, QMacStyle etc.). By default, these styles are built into the Qt GUI module. Styles can also be made available as plugins.
Qt's built-in widgets use QStyle to perform nearly all of their drawing, ensuring that they look exactly like the equivalent native widgets. The diagram below shows a QComboBox in nine different styles.
Nine combo boxes

Draws the given control using the provided painter with the style options specified by option.
The widget argument is optional and can be used as aid in drawing the control.
The option 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 option 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 \l {QStyle::StateFlag}{style flags} that are used when drawing.

Returns the area within the given rectangle in which to draw the provided text according to the specified font metrics and alignment.
The enabled parameter indicates whether or not the associated item is enabled.
If the given rectangle is larger than the area needed to render the text, the rectangle that is returned will be offset within rectangle according to the specified alignment. For example, if alignment is Qt::AlignCenter, the returned rectangle will be centered within rectangle. If the given rectangle is smaller than the area needed, the returned rectangle will be the smallest rectangle large enough to render the text.

Returns the value of the given pixel metric.
The specified option and widget can be used for calculating the metric. The option can be cast to the appropriate type using the qstyleoption_cast() function. Note that the option may be zero even for PixelMetrics that can make use of it. See the table below for the appropriate option 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.

Initializes the appearance of the given widget.
This function is called for every widget at some point after it has been fully created but just before it is shown for the very first time.
Note that the default implementation does nothing. Reasonable actions in this function might be to call the QWidget::setBackgroundMode() function for the widget. Do not use the function to set, for example, the geometry. Reimplementing this function provides a back-door through which the appearance of a widget can be changed, but with Qt's style engine it is rarely necessary to implement this function; reimplement drawItemPixmap(), drawItemText(), drawPrimitive(), etc. instead.
The QWidget::inherits() function may provide enough information to allow class-specific customizations. But because new QStyle subclasses are expected to work reasonably with all current and future widgets, limited use of hard-coded customization is recommended.

Converts the given logicalValue to a pixel position.
The min parameter maps to 0, max maps to span and other values are distributed evenly in-between.
This function can handle the entire integer range without overflow, providing that span is less than 4096.
By default, this function assumes that the maximum value is on the right for horizontal items and on the bottom for vertical items. Set the upsideDown parameter to true to reverse this behavior.

Uninitialize the given {widget}'s appearance.
This function is the counterpart to polish(). It is called for every polished widget whenever the style is dynamically changed; the former style has to unpolish its settings before the new style can polish them again.
Note that unpolish() will only be called if the widget is destroyed. This can cause problems in some cases, e.g, if you remove a widget from the UI, cache it, and then reinsert it after the style has changed; some of Qt's classes cache their widgets.
