48 \class QSGSimpleRectNode
50 \brief The QSGSimpleRectNode class is a convenience class for drawing
51 solid filled rectangles using scenegraph.
58 Constructs a QSGSimpleRectNode instance which is spanning \a rect with
61 QSGSimpleRectNode::QSGSimpleRectNode(const QRectF &rect, const QColor &color)
62 : m_geometry(QSGGeometry::defaultAttributes_Point2D(), 4)
64 QSGGeometry::updateRectGeometry(&m_geometry, rect);
65 m_material.setColor(color);
66 setMaterial(&m_material);
67 setGeometry(&m_geometry);
73 Constructs a QSGSimpleRectNode instance with an empty rectangle and
76 QSGSimpleRectNode::QSGSimpleRectNode()
77 : m_geometry(QSGGeometry::defaultAttributes_Point2D(), 4)
79 QSGGeometry::updateRectGeometry(&m_geometry, QRectF());
80 setMaterial(&m_material);
81 setGeometry(&m_geometry);
87 Sets the rectangle of this rect node to \a rect.
89 void QSGSimpleRectNode::setRect(const QRectF &rect)
91 QSGGeometry::updateRectGeometry(&m_geometry, rect);
92 markDirty(QSGNode::DirtyGeometry);
98 Returns the rectangle that this rect node covers.
100 QRectF QSGSimpleRectNode::rect() const
102 const QSGGeometry::Point2D *pts = m_geometry.vertexDataAsPoint2D();
103 return QRectF(pts[0].x,
106 pts[3].y - pts[0].y);
111 Sets the color of this rectangle to \a color. The default
114 void QSGSimpleRectNode::setColor(const QColor &color)
116 if (color != m_material.color()) {
117 m_material.setColor(color);
118 markDirty(QSGNode::DirtyMaterial);
125 Returns the color of this rectangle.
127 QColor QSGSimpleRectNode::color() const
129 return m_material.color();
