[override virtual] QSGRectangleNode:: ~QSGRectangleNode ()

Destroys the instance of QSGRectangleNode. The destructor is virtual.

[pure virtual] QColor QSGRectangleNode:: color () const

Returns the color of this rectangle.

另请参阅 setColor ().

[pure virtual] QRectF QSGRectangleNode:: rect () const

Returns the rectangle that this rect node covers.

另请参阅 setRect ().

[pure virtual] void QSGRectangleNode:: setColor (const QColor & color )

Sets the color of this rectangle to color . The default color will be white.

另请参阅 color ().

[pure virtual] void QSGRectangleNode:: setRect (const QRectF & rect )

Sets the rectangle of this rect node to rect .

另请参阅 rect ().

void QSGRectangleNode:: setRect ( qreal x , qreal y , qreal w , qreal h )

这是重载函数。

Sets the rectangle of this rect node to begin at ( x , y ) and have width w 和高度 h .
