A legend item representing a plottable with an icon and the plottable name.
This is the standard legend item for plottables. It displays an icon of the plottable next to the plottable name. The icon is drawn by the respective plottable itself (QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable. For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the middle.
Legend items of this type are always associated with one plottable (retrievable via the plottable() function and settable with the constructor). You may change the font of the plottable name with setFont. Icon padding and border pen is taken from the parent QCPLegend, see QCPLegend::setIconBorderPen and QCPLegend::setIconTextPadding.
The function QCPAbstractPlottable::addToLegend/QCPAbstractPlottable::removeFromLegend creates/removes legend items of this type in the default implementation. However, these functions may be reimplemented such that a different kind of legend item (e.g a direct subclass of QCPAbstractLegendItem) is used for that plottable.
Since QCPLegend is based on QCPLayoutGrid, a legend item itself is just a subclass of QCPLayoutElement. While it could be added to a legend (or any other layout) via the normal layout interface, QCPLegend has specialized functions for handling legend items conveniently, see the documentation of QCPLegend.
| QCPPlottableLegendItem::QCPPlottableLegendItem | ( | QCPLegend * | parent, |
| QCPAbstractPlottable * | plottable | ||
| ) |
Creates a new legend item associated with plottable.
Once it's created, it can be added to the legend via QCPLegend::addItem.
A more convenient way of adding/removing a plottable to/from the legend is via the functions QCPAbstractPlottable::addToLegend and QCPAbstractPlottable::removeFromLegend.

Returns the minimum size this layout element (the inner rect) may be compressed to.
if a minimum size (setMinimumSize) was not set manually, parent layouts consult this function to determine the minimum allowed size of this layout element. (A manual minimum size is considered set if it is non-zero.)
