## Detailed Description
该QStyleOption类存储所使用的参数[QStyle](qstyle.html)功能。
QStyleOption及其子类包含的所有信息,[QStyle](qstyle.html)功能需要绘制的图形元素。
出于性能方面的原因,也有一些成员函数和访问成员变量是直接的(即使用`.` or `->`操作符)。这种低层次的感觉,使结构简单的使用,并强调这些只是所用的样式函数的参数。
的调用者[QStyle](qstyle.html)功能通常在栈上创建QStyleOption对象。这种结合Qt的广泛使用[implicit sharing](index.htm)对于类型如[QString](qstring.html),[QPalette](qpalette.html)和[QColor](qcolor.html)确保没有内存分配不必要的发生。
下面的代码片段显示了如何使用特定QStyleOption子类来绘制一个按钮:
```
void MyPushButton.paintEvent([QPaintEvent](qpaintevent.html) *)
{
[QStyleOptionButton](qstyleoptionbutton.html) option;
option.initFrom(this);
option.state = isDown() ? [QStyle](qstyle.html).State_Sunken : [QStyle](qstyle.html).State_Raised;
if (isDefault())
option.features |= [QStyleOptionButton](qstyleoptionbutton.html).DefaultButton;
option.text = text();
option.icon = icon();
[QPainter](qpainter.html) painter(this);
style()->drawControl([QStyle](qstyle.html).CE_PushButton, &option, &painter, this);
}
```
在我们的例子中,控制是一个[QStyle.CE_PushButton](qstyle.html#ControlElement-enum),并根据该[QStyle.drawControl](qstyle.html#drawControl)( )文档对应的类是[QStyleOptionButton](qstyleoptionbutton.html)。
当重新实现[QStyle](qstyle.html)它接受一个QStyleOption参数功能,你经常需要转换QStyleOption到一个子类。为安全起见,你可以使用[qstyleoption_cast](qstyleoption.html#qstyleoption_cast)( ),以确保该指针的类型是正确的。例如:
```
void MyStyle.drawPrimitive(PrimitiveElement element,
const QStyleOption *option,
[QPainter](qpainter.html) *painter,
const [QWidget](qwidget.html) *widget)
{
if (element == PE_FrameFocusRect) {
const [QStyleOptionFocusRect](qstyleoptionfocusrect.html) *focusRectOption =
qstyleoption_cast<const [QStyleOptionFocusRect](qstyleoptionfocusrect.html) *>(option);
if (focusRectOption) {
// ...
}
}
// ...
}
```
该[qstyleoption_cast](qstyleoption.html#qstyleoption_cast)()函数将返回0,如果该对象,其中`option`点是正确的类型。
举一个例子展示风格选择如何使用,请参阅[Styles](index.htm)例子。
