Detailed Description

The QSGBasicGeometryNode class serves as a baseclass for geometry based nodes.

\inmodule QtQuick

The QSGBasicGeometryNode class should not be used by itself. It is only encapsulates shared functionality between the QSGGeometryNode and QSGClipNode classes.

Note

All classes with QSG prefix should be used solely on the scene graph's rendering thread. See \l {Scene Graph and Rendering} for more information.

Constructor & Destructor Documentation

~QSGBasicGeometryNode()

QSGBasicGeometryNode::~QSGBasicGeometryNode ( )

override

Deletes this QSGBasicGeometryNode.

If the node has the flag QSGNode::OwnsGeometry set, it will also delete the geometry object it is pointing to. This flag is not set by default.

Definition at line 698 of file qsgnode.cpp.

Here is the call graph for this function:

QSGBasicGeometryNode() [1/2]

QSGBasicGeometryNode::QSGBasicGeometryNode ( NodeType type )

protected

Creates a new basic geometry node of type type.

Member Function Documentation

clipList()

QSGClipNode * QSGBasicGeometryNode::clipList ( ) const

inline

Will be set during rendering to contain the clip of the geometry for that rendering pass.

Here is the caller graph for this function:

geometry() [1/2]

QSGGeometry * QSGBasicGeometryNode::geometry ( )

inline

Returns this node's geometry.

The geometry is null by default.

inline

Returns this node's geometry.

The geometry is null by default.

matrix()

QMatrix4x4 * QSGBasicGeometryNode::matrix ( ) const

inline

Will be set during rendering to contain transformation of the geometry for that rendering pass.

Definition at line 163 of file qsgnode.h.

Referenced by QSGBatchRenderer::Element::computeBounds(), QSGBatchRenderer::Batch::isSafeToBatch(), and QSGBatchRenderer::qsg_matrixForRoot().

Here is the caller graph for this function:

setGeometry()

void QSGBasicGeometryNode::setGeometry

(

QSGGeometry *

geometry

)

Sets the geometry of this node to geometry.

If the node has the flag QSGNode::OwnsGeometry set, it will also delete the geometry object it is pointing to. This flag is not set by default.

If the geometry is changed without calling setGeometry() again, the user must also mark the geometry as dirty using QSGNode::markDirty().
