Re: [Interest] How to hide the QSGGeometryNode?

Please make a minimal testcase. The code above seems incomplete (e.g. no
calls to markDirty to update those dirty bits).

Hi. Yes, now I use this in a form of:
bool CurveNode::isSubtreeBlocked() const
{
return QSGGeometryNode::isSubtreeBlocked() || !m_visible;
}
void CurveNode::setVisible(bool visible)
{if (m_visible == visible)return;m_visible = visible;
if (!m_visible)m_dirtyState |= DirtySubtreeBlocked;else
m_dirtyState |= DirtyOpacity;
}
but, when I call the setVisible(true) infide of updatePaintNode(), then I
got an assert:
ASSERT: "shadowNode" in file scenegraph\coreapi\qsgbatchrenderer.cpp, line
1293
and, the node does not appeared again as a visible.

[Interest] How to hide the QSGGeometryNode?
Hi all. I have an own class, derived from the QQuIckItem. This class contains a multiple child QSGGeometryNode-s. Each node has own fragment && vertex shader. Each node draws a curves, which are specified by a points set to a vertex array. So, I need possibility to hide any selected QSGGeometryNode (i.e. do not draw it). How to do it in a right way?
