Member Function Documentation

Q3DSurface::Q3DSurface(const QSurfaceFormat *format = nullptr, QWindow *parent = nullptr)

Constructs a new 3D surface graph with optional parent window and surface format.

[virtual] Q3DSurface::~Q3DSurface()

Destroys the 3D surface graph.

void Q3DSurface::addAxis(QValue3DAxis *axis)

Adds axis to the graph. The axes added via addAxis are not yet taken to use, addAxis is simply used to give the ownership of the axis to the graph. The axis must not be null or added to another graph.

See also releaseAxis(), setAxisX(), setAxisY(), and setAxisZ().

void Q3DSurface::addSeries(QSurface3DSeries *series)

Adds the series to the graph. A graph can contain multiple series, but has only one set of axes. If the newly added series has specified a selected item, it will be highlighted and any existing selection will be cleared. Only one added series can have an active selection.

QList<QValue3DAxis *> Q3DSurface::axes() const

Returns the list of all added axes.

See also addAxis().

void Q3DSurface::releaseAxis(QValue3DAxis *axis)

Releases the ownership of the axis back to the caller, if it is added to this graph. If the released axis is in use, a new default axis will be created and set active.

If the default axis is released and added back later, it behaves as any other axis would.

See also addAxis(), setAxisX(), setAxisY(), and setAxisZ().

void Q3DSurface::removeSeries(QSurface3DSeries *series)

Removes the series from the graph.

QList<QSurface3DSeries *> Q3DSurface::seriesList() const

Returns the list of series added to this graph.

void Q3DSurface::setAxisX(QValue3DAxis *axis)

Sets axis as the active x-axis. Implicitly calls addAxis() to transfer the ownership of the axis to this graph.

If axis is null, a temporary default axis with no labels and an automatically adjusting range is created.

This temporary axis is destroyed if another axis is set explicitly to the same orientation.

Note: Setter function for property axisX.

See also axisX(), addAxis(), and releaseAxis().

void Q3DSurface::setAxisY(QValue3DAxis *axis)

Sets axis as the active y-axis. Implicitly calls addAxis() to transfer the ownership of the axis to this graph.

If axis is null, a temporary default axis with no labels and an automatically adjusting range is created.

This temporary axis is destroyed if another axis is set explicitly to the same orientation.

Note: Setter function for property axisY.

See also axisY(), addAxis(), and releaseAxis().

void Q3DSurface::setAxisZ(QValue3DAxis *axis)

Sets axis as the active z-axis. Implicitly calls addAxis() to transfer the ownership of the axis to this graph.

If axis is null, a temporary default axis with no labels and an automatically adjusting range is created.

This temporary axis is destroyed if another axis is set explicitly to the same orientation.

Note: Setter function for property axisZ.

See also axisZ(), addAxis(), and releaseAxis().
