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 via QQuickWindow::createRectangleNode () 或 QSGEngine::createRectangleNode ().

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
