详细描述
The QSGSimpleRectNode class is a convenience class for drawing solid filled rectangles using scenegraph.
Warning: 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() or QSGEngine::createRectangleNode().
成员函数
QSGSimpleRectNode::QSGSimpleRectNode(const QRectF &rect, const QColor &color)
Constructs a QSGSimpleRectNode instance which is spanning rect with the color color.
QSGSimpleRectNode::QSGSimpleRectNode()
Constructs a QSGSimpleRectNode instance with an empty rectangle and white color.
QColor QSGSimpleRectNode::color() const
Returns the color of this rectangle.
参见 setColor().
QRectF QSGSimpleRectNode::rect() const
Returns the rectangle that this rect node covers.
参见 setRect().
void QSGSimpleRectNode::setColor(const QColor &color)
Sets the color of this rectangle to color. The default color will be white.
参见 color().
void QSGSimpleRectNode::setRect(const QRectF &rect)
Sets the rectangle of this rect node to rect.
参见 rect().
void QSGSimpleRectNode::setRect(qreal x, qreal y, qreal w, qreal h)
This is an overloaded function.
Sets the rectangle of this rect node to begin at (x, y) and have width w and height h.
