Detailed Description

Base class for all objects that can be placed on layers.

This is the abstract base class most visible objects derive from, e.g. plottables, axes, grid etc.

Every layerable is on a layer (QCPLayer) which allows controlling the rendering order by stacking the layers accordingly.

For details about the layering mechanism, see the QCPLayer documentation.

Constructor & Destructor Documentation

QCPlot::QCPLayerable::QCPLayerable

(

QCustomPlot *

parentPlot

)

Creates a new QCPLayerable instance.

Since QCPLayerable is an abstract base class, it can't be instantiated directly. Use one of the derived classes.

Member Function Documentation

void QCPlot::QCPLayerable::setAntialiased

(

bool

enabled

)

Sets whether this object will be drawn antialiased or not.

Note that antialiasing settings may be overridden by QCustomPlot::setAntialiasedElements and QCustomPlot::setNotAntialiasedElements.

bool QCPlot::QCPLayerable::setLayer

(

QCPLayer *

layer

)

Sets the layer of this layerable object.

The object will be placed on top of the other objects already on layer.

Returns true on success, i.e. if layer is a valid layer.

bool QCPlot::QCPLayerable::setLayer

(

const QString &

layerName

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Sets the layer of this layerable object by name.

Returns true on success, i.e. if layerName is a valid layer name.

void QCPlot::QCPLayerable::setVisible

(

bool

on

)

Sets the visibility of this layerable object.

If an object is not visible, it will not be drawn on the QCustomPlot surface, and user interaction with it (e.g. click/selection) is not possible.
