详细描述

QSGSimpleRectNode class is a convenience class for drawing solid filled rectangles using scenegraph.

警告： This utility class is only functional when running with the OpenGL or software backends of the Qt Quick scenegraph. For a proper cross-platform alternative prefer using QSGRectangleNode 凭借 QQuickWindow::createRectangleNode () 或 QSGEngine::createRectangleNode ().

成员函数文档编制

QSGSimpleRectNode:: QSGSimpleRectNode (const QRectF & rect , const QColor & color )

构造 QSGSimpleRectNode instance which is spanning rect with the color color .

QSGSimpleRectNode:: QSGSimpleRectNode ()

构造 QSGSimpleRectNode instance with an empty rectangle and white color.

QColor QSGSimpleRectNode:: color () const

Returns the color of this rectangle.

另请参阅 setColor ().

QRectF QSGSimpleRectNode:: rect () const

Returns the rectangle that this rect node covers.

另请参阅 setRect ().

void QSGSimpleRectNode:: setColor (const QColor & color )

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

另请参阅 color ().

void QSGSimpleRectNode:: setRect (const QRectF & rect )

Sets the rectangle of this rect node to rect .

另请参阅 rect ().

void QSGSimpleRectNode:: 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 .
