LARS
LARS (Light Augmented Reality System) is an open-source framework for light-based interaction and real-time tracking in multi-robot experiments. Inspired by ARK, LARS extends the augmented reality paradigm to robotic collectives by projecting dynamic visual cues and environments onto the arena, enabling new experimental possibilities for collective robotics research, education, and outreach. LARS features integrated tracking, light projection, and modular experiment control with a user-friendly Qt GUI.

Detailed Description

The abstract base class for all entries in a QCPLegend.

It defines a very basic interface for entries in a QCPLegend. For representing plottables in the legend, the subclass QCPPlottableLegendItem is more suitable.

Only derive directly from this class when you need absolute freedom (e.g. a custom legend entry that's not even associated with a plottable).

You must implement the following pure virtual functions:

You inherit the following members you may use:

QCPLegend *mParentLegend A pointer to the parent QCPLegend.
QFont mFont The generic font of the item. You should use this font for all or at least the most prominent text of the item.

Constructor & Destructor Documentation

◆ QCPAbstractLegendItem()

QCPAbstractLegendItem::QCPAbstractLegendItem ( QCPLegend * parent)
explicit

Constructs a QCPAbstractLegendItem and associates it with the QCPLegend parent. This does not cause the item to be added to parent, so QCPLegend::addItem must be called separately.

Member Function Documentation

◆ applyDefaultAntialiasingHint()

void QCPAbstractLegendItem::applyDefaultAntialiasingHint ( QCPPainter * painter) const
protectedvirtual

Reimplemented from QCPLayoutElement.

◆ clipRect()

QRect QCPAbstractLegendItem::clipRect ( ) const
protectedvirtual

◆ deselectEvent()

void QCPAbstractLegendItem::deselectEvent ( bool * selectionStateChanged)
protectedvirtual

Reimplemented from QCPLayerable.

◆ draw()

virtual void QCPAbstractLegendItem::draw ( QCPPainter * painter)
protectedpure virtual

Reimplemented from QCPLayoutElement.

◆ selectEvent()

void QCPAbstractLegendItem::selectEvent ( QMouseEvent * event,
bool additive,
const QVariant & details,
bool * selectionStateChanged )
protectedvirtual

Reimplemented from QCPLayerable.

◆ selectionCategory()

QCP::Interaction QCPAbstractLegendItem::selectionCategory ( ) const
protectedvirtual

Reimplemented from QCPLayerable.

◆ selectionChanged

void QCPAbstractLegendItem::selectionChanged ( bool selected)
signal

This signal is emitted when the selection state of this legend item has changed, either by user interaction or by a direct call to setSelected.

◆ selectTest()

double QCPAbstractLegendItem::selectTest ( const QPointF & pos,
bool onlySelectable,
QVariant * details = nullptr ) const
virtual

Layout elements are sensitive to events inside their outer rect. If pos is within the outer rect, this method returns a value corresponding to 0.99 times the parent plot's selection tolerance. However, layout elements are not selectable by default. So if onlySelectable is true, -1.0 is returned.

See QCPLayerable::selectTest for a general explanation of this virtual method.

QCPLayoutElement subclasses may reimplement this method to provide more specific selection test behaviour.

Reimplemented from QCPLayoutElement.

◆ setFont()

void QCPAbstractLegendItem::setFont ( const QFont & font)

Sets the default font of this specific legend item to font.

See also
setTextColor, QCPLegend::setFont

◆ setSelectable()

void QCPAbstractLegendItem::setSelectable ( bool selectable)

Sets whether this specific legend item is selectable.

See also
setSelectedParts, QCustomPlot::setInteractions

◆ setSelected()

void QCPAbstractLegendItem::setSelected ( bool selected)

Sets whether this specific legend item is selected.

It is possible to set the selection state of this item by calling this function directly, even if setSelectable is set to false.

See also
setSelectableParts, QCustomPlot::setInteractions

◆ setSelectedFont()

void QCPAbstractLegendItem::setSelectedFont ( const QFont & font)

When this legend item is selected, font is used to draw generic text, instead of the normal font set with setFont.

See also
setFont, QCPLegend::setSelectedFont

◆ setSelectedTextColor()

void QCPAbstractLegendItem::setSelectedTextColor ( const QColor & color)

When this legend item is selected, color is used to draw generic text, instead of the normal color set with setTextColor.

See also
setTextColor, QCPLegend::setSelectedTextColor

◆ setTextColor()

void QCPAbstractLegendItem::setTextColor ( const QColor & color)

Sets the default text color of this specific legend item to color.

setFont, QCPLegend::setTextColor
